Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`static void`	`create()` RPCRequest shouldn't be created directly.
`java.lang.String`	`getActionURL()` Overrides RPCManager.actionURL for this request only.
`java.lang.Boolean`	`getAllowIE9Leak()` Advanced flag to avoid a potential memory leak in Internet Explorer 9 for requests with JSON formatted responses.
`java.lang.Boolean`	`getBypassCache()` For xmlHttp transport + httpMethod: "GET" only, set to true to force a conditional GET request even if the browser thinks it has a current cached response.
`java.lang.String`	`getCallbackParam()` For use only with the `scriptInclude` transport, this attribute specifies the name of the URL parameter which is used to specify the callback function that the server is expected to call by writing out JavaScript code.
`java.lang.Boolean`	`getContainsCredentials()` For use during `Relogin`, this property marks this request an attempt to login, therefore a response containing the `loginRequiredMarker` is a normal condition and should result in the status code `STATUS_LOGIN_INCORRECT` rather than a call to `loginRequired()`.
`java.lang.String`	`getContentType()` Valid with the xmlHttpRequest transport only and only when `httpMethod` is set to "POST".
`com.google.gwt.core.client.JavaScriptObject`	`getData()` Returns the payload of this request to be sent to the server, as a JavaScriptObject.
`java.lang.String`	`getDataAsString()`
`java.lang.Boolean`	`getDownloadResult()` If enabled, causes the RPCRequest to download the requested resource as a file, either showing the browser's Save dialog or displaying the file-content in `a new browser window`.
`java.lang.Boolean`	`getDownloadToNewWindow()` When `downloadResult` is true, setting this attribute to true causes the content of the downloaded file to be displayed in a new browser window.
`java.lang.Boolean`	`getEvalResult()` This works similarly to `serverOutputAsString` except the resulting String is automatically evaluated as JavaScript.
`java.util.Map`	`getHttpHeaders()` HTTP headers to send, as a Object mapping Header name -> Header value, eg { "Content-Type" : "text/xml" }
`java.lang.String`	`getHttpMethod()` Selects the HTTP method that will be used for the request.
`java.lang.String`	`getHttpProxyURL()` The proxy URL to use for this request (if `useHttpProxy` is set for this request).
`java.lang.Boolean`	`getIgnoreTimeout()` When set to true, no reply is expected from the server.
`java.lang.Boolean`	`getOmitNullMapValuesInResponse()` If enabled, the server omits any key/value pairs in map that have null values from the response.
`static RPCRequest`	`getOrCreateRef(com.google.gwt.core.client.JavaScriptObject jsObj)`
`java.util.Map`	`getParams()` Values to be sent as simple HTTP params, as a JavaScript Object where each property/value pair will become an HTTP parameter name and value.
`java.lang.String`	`getPrompt()` Overrides RPCManager.defaultPrompt for this request only.
`java.lang.String`	`getPromptCursor()` Controls the cursor shown when `promptStyle` is set to `"cursor"` for this request only.

`java.lang.Boolean`	`getSendNoQueue()` When set to true, this request is sent to the server immediately, bypassing any current queue.
`java.lang.Boolean`	`getServerOutputAsString()` Setting this flag makes the body of the HTTP response available as a String in the `callback` as `RPCResponse.data`.
`java.lang.Boolean`	`getShowPrompt()` Overrides `RPCManager.showPrompt` for this request only.
`java.lang.Boolean`	`getSuppressAutoDraw()` If `evalResult` is set, setting this property to true causes `Canvas.autoDraw` to be set to false for the duration of the result evaluation - which is generally what you want if you're returning new components from the server.
`java.lang.Integer`	`getTimeout()` Sets the timeout on this request.
`RPCTransport`	`getTransport()` Selects the transport used for this RPCRequest.
`java.lang.Boolean`	`getUseHttpProxy()` Indicates whether this request should use the HttpProxyServlet in order to enable contacting hosts other than the origin server (available only in Pro Edition or better).
`java.lang.Boolean`	`getUseSimpleHttp()` When set to true, assume the request is not going to the Smart GWT server, and hence send a simple HTTP request that does not use Smart GWT-specific request encoding.
`java.lang.Boolean`	`getWillHandleError()` With willHandleError:false, rpcResponses that indicate an error go through centralized handling in the RPCManager and rpcRequest.callback is never invoked.
`java.lang.Boolean`	`getWithCredentials()` In browsers that support Cross-Origin Resource Sharing and XMLHttpRequest 2, and where the service at the `actionURL` allows the origin to send credentials (see `Access-Control-Allow-Credentials`), should user credentials such as cookies, HTTP authentication, and client-side SSL certificates be sent with the actual CORS request?

Method Detail

getOrCreateRef

public static RPCRequest getOrCreateRef(com.google.gwt.core.client.JavaScriptObject jsObj)

setActionURL
```
public void setActionURL(java.lang.String actionURL)
```
Overrides RPCManager.actionURL for this request only. If you're using queuing, note that queues as per-URL - in other words all RPCRequests in a queue must go to a single URL. If you attempt to send a request with an actionURL that is different from those already in the queue, it will be sent to the server separately, ahead of the queue, and a warning will be logged to the Developer Console.

Parameters:

actionURL - Default value is RPCManager.actionURL

See Also:

com.smartgwt.client.rpc.RPCManager#actionURL

getActionURL
```
public java.lang.String getActionURL()
```
Overrides RPCManager.actionURL for this request only. If you're using queuing, note that queues as per-URL - in other words all RPCRequests in a queue must go to a single URL. If you attempt to send a request with an actionURL that is different from those already in the queue, it will be sent to the server separately, ahead of the queue, and a warning will be logged to the Developer Console.

Returns:

String

setAllowIE9Leak
```
public void setAllowIE9Leak(java.lang.Boolean allowIE9Leak)
```
Advanced flag to avoid a potential memory leak in Internet Explorer 9 for requests with JSON formatted responses.
This attribute may be set to false to explicitly enable the workaround described here for this request, avoiding a potential memory leak in Internet Explorer 9.
This workaround has a limitation in that if parsing the JSON response generates certain object types including JavaScript Date or function objects, attempts to interact with these objects can subsequently lead to a JavaScript error with the message "Can't execute code from a freed script".
This workaround therefore may not be suitable for all transactions or dataSources within a given application.
This property may also be set globally within an application (via allowIE9Leak)_.
Note: This memory leak and workaround is discussed further in the online Smart GWT FAQ.
Note : This is an advanced setting

Parameters:

allowIE9Leak - Default value is null

getAllowIE9Leak
```
public java.lang.Boolean getAllowIE9Leak()
```

Returns:

Boolean

setBypassCache
```
public void setBypassCache(java.lang.Boolean bypassCache)
```
For xmlHttp transport + httpMethod: "GET" only, set to true to force a conditional GET request even if the browser thinks it has a current cached response.
Note : This is an advanced setting

Parameters:

bypassCache - Default value is false

getBypassCache
```
public java.lang.Boolean getBypassCache()
```
For xmlHttp transport + httpMethod: "GET" only, set to true to force a conditional GET request even if the browser thinks it has a current cached response.

Returns:

Boolean

setCallbackParam
```
public void setCallbackParam(java.lang.String callbackParam)
```
For use only with the scriptInclude transport, this attribute specifies the name of the URL parameter which is used to specify the callback function that the server is expected to call by writing out JavaScript code. The actual function to call is automatically generated and differs for every request (to allow concurrency).
For example, with callbackParam set to it's default value of "callback", the server might be contacted with a URL like:
```
     loadData?callback=isc_scriptIncludeCallback_5
  
```
.. then the server's response should look like:
```
     isc_scriptIncludeCallback_5({ .. data .. });
  
```
The name "isc_scriptIncludeCallback_5" is automatically generated and will differ each time the server is contacted.
Smart GWT makes of this server-provided callback mechanism, then calls callback normally.
rpcRequest.callbackParam is ignored by all transport other than scriptInclude.
Parameters:

callbackParam - Default value is "callback"

getCallbackParam
```
public java.lang.String getCallbackParam()
```
For use only with the scriptInclude transport, this attribute specifies the name of the URL parameter which is used to specify the callback function that the server is expected to call by writing out JavaScript code.

```
.. then the server's response should look like:
```
     isc_scriptIncludeCallback_5({ .. data .. });
  
```
The name "isc_scriptIncludeCallback_5" is automatically generated and will differ each time the server is contacted.
Smart GWT makes of this server-provided callback mechanism, then calls callback normally.
rpcRequest.callbackParam is ignored by all transport other than scriptInclude.
Returns:

String

setContainsCredentials
```
public void setContainsCredentials(java.lang.Boolean containsCredentials)
```
For use during Relogin, this property marks this request an attempt to login, therefore a response containing the loginRequiredMarker is a normal condition and should result in the status code STATUS_LOGIN_INCORRECT rather than a call to loginRequired().
It is not required to set containsCredentials, however, it does typically simplify relogin logic by separating the handling of RPCs that are login attempts from RPCs that are not.
Note : This is an advanced setting

Parameters:

containsCredentials - Default value is false

See Also:

Relogin overview and related methods

getContainsCredentials
```
public java.lang.Boolean getContainsCredentials()
```
For use during Relogin, this property marks this request an attempt to login, therefore a response containing the loginRequiredMarker is a normal condition and should result in the status code STATUS_LOGIN_INCORRECT rather than a call to loginRequired().
It is not required to set containsCredentials, however, it does typically simplify relogin logic by separating the handling of RPCs that are login attempts from RPCs that are not.

Returns:

Boolean

setContentType
```
public void setContentType(java.lang.String contentType)
```
Valid with the xmlHttpRequest transport only and only when httpMethod is set to "POST".

Parameters:

contentType - Default value is "application/x-www-form-urlencoded"

getContentType
```
public java.lang.String getContentType()
```
Valid with the xmlHttpRequest transport only and only when httpMethod is set to "POST".

Returns:

String

setData

public void setData(java.lang.String data)

This attribute specifies the payload of the RPCRequest. When using the Smart GWT server, objects sent to the server as request.data will be available on the server-side RPCRequest object as Java Objects. This is achieved by serializing the client side data in a JSON type format and generating Java Objects on the server from this serialized data.

If the client side request.data is set to a Java object in your SmartGWT code it will be serialized as JSON as follows:
- Numeric client side values (int, Integer, etc) will be serialized as JavaScript numbers.
- String values will be serialized as JavaScript strings.
- Date values will be serialized as JavaScript dates.
- Maps or Record objects will be serialized as JavaScript Objects.
- Arrays or Lists will become JavaScript arrays
Serialization of Maps and Arrays is recursive - each entry in an Array, or attribute on a Map will also be serialized according to the above rules.
Note that you can also set request.data directly to a JavaScriptObject, and use the JSOHelper class or SomeObject.getJSObj() to perform your own data conversions on the client. The serialized JavaScript will then be converted back to Java on the server according to the following rules.

Here are the mapping of JavaScript types to their corresponding server object types:

JS Type	Java Type
Object: {}	Map
Array: []	List
String	String
Number	Long\|Double
Boolean	Boolean
Date	java.util.Date
String	com.smartgwt.client.types.ValueEnum

Note that the order of keys/values in the Maps created on the server is not guaranteed because JavaScript Object literals do not guarantee order.

When using JPA or Hibernate Java value used can be affected by the Java Bean declaration. See DsRequestBeanTypes for details.

Server->client conversion follows this table as well, with some extras. See the toJS() method on JSTranslater in the server documentation for a description of additional behaviors.

When not communicating with the Smart GWT server, rpcRequest.data becomes simple HTTP parameters or an HTTP request body - see useSimpleHttp for details.

Parameters:: data - Default value is null
See Also:: com.smartgwt.client.rpc.RPCResponse#setData

public void setData(Record data)

Here are the mapping of JavaScript types to their corresponding server object types:

JS Type	Java Type

Parameters:: data - Default value is null
See Also:: com.smartgwt.client.rpc.RPCResponse#setData

setDownloadResult
```
public void setDownloadResult(java.lang.Boolean downloadResult)
```
If enabled, causes the RPCRequest to download the requested resource as a file, either showing the browser's Save dialog or displaying the file-content in a new browser window.
Setting this attribute to true means that no callback will be fired and implies that the request will silently use transport: "hiddenFrame".
Note : This is an advanced setting

Parameters:

downloadResult - Default value is false

getDownloadResult
```
public java.lang.Boolean getDownloadResult()
```
If enabled, causes the RPCRequest to download the requested resource as a file, either showing the browser's Save dialog or displaying the file-content in a new browser window.
Setting this attribute to true means that no callback will be fired and implies that the request will silently use transport: "hiddenFrame".

Returns:

Boolean

setDownloadToNewWindow
```
public void setDownloadToNewWindow(java.lang.Boolean downloadToNewWindow)
```
When downloadResult is true, setting this attribute to true causes the content of the downloaded file to be displayed in a new browser window.
Note : This is an advanced setting

Parameters:

downloadToNewWindow - Default value is false

getDownloadToNewWindow
```
public java.lang.Boolean getDownloadToNewWindow()
```
When downloadResult is true, setting this attribute to true causes the content of the downloaded file to be displayed in a new browser window.

Returns:

Boolean

setEvalResult
```
public void setEvalResult(java.lang.Boolean evalResult)
```
This works similarly to serverOutputAsString except the resulting String is automatically evaluated as JavaScript. The result of the evaluation is then passed to any specified callback as RPCResponse.data.
This feature can be used to dynamically load new application modules into a running application. An RPCRequest with evalResult enabled can be used to fetch a static .js file or JavaScript dynamically generated by the server. The returned JavaScript can contain anything that a JavaScript file loaded at init time can contain, including new views and new Smart GWT class definitions.
Example usage with RPCManager.sendRequest():
```
  isc.RPCManager.sendRequest({
      evalResult:true,
      actionURL:"js/loadLabel.js",
      evalVars:{var1:"A Value"}
  });
  
```
This call would execute the code from loadLabel.js, and make the variable var1 available to that code. Therefore if the .js file contained this code:
```
  isc.Label.create({
      contents:var1
  })
  
```
A label would be created with contents set to the value of var1 - the string "A Value".
This feature relies on the XMLHttpRequest object which can be disabled by end-users in some supported browsers. See PlatformDependencies for more information.
Note : This is an advanced setting
Parameters:

evalResult - Default value is false

setEvalVars
```
public void setEvalVars(java.util.Map evalVars)
```
If you've set evalResult : true, then the property values of this object will be available in the evaluation scope of the result under the variable names specified by the property names.
So e.g. if evalVars is: {foo: "bar"} then a reference to the variable foo in the result will evaluate to "bar".
Note : This is an advanced setting

Parameters:

evalVars - Default value is null

setHttpHeaders
```
public void setHttpHeaders(java.util.Map httpHeaders)
```
HTTP headers to send, as a Object mapping Header name -> Header value, eg

Valid with the xmlHttpRequest transport only.

Returns:

Map

setHttpMethod
```
public void setHttpMethod(java.lang.String httpMethod)
```
Selects the HTTP method that will be used for the request. Typical values are "POST" and "GET".

setIgnoreTimeout
```
public void setIgnoreTimeout(java.lang.Boolean ignoreTimeout)
```
When set to true, no reply is expected from the server. However, if a reply is received, it will be processed.
Note: setting this to true, forces sendNoQueue to true for this request.
Note : This is an advanced setting

Parameters:

ignoreTimeout - Default value is false

getIgnoreTimeout
```
public java.lang.Boolean getIgnoreTimeout()
```
When set to true, no reply is expected from the server. However, if a reply is received, it will be processed.
Note: setting this to true, forces sendNoQueue to true for this request.

Returns:

Boolean

setOmitNullMapValuesInResponse
```
public void setOmitNullMapValuesInResponse(java.lang.Boolean omitNullMapValuesInResponse)
```
If enabled, the server omits any key/value pairs in map that have null values from the response. This can reduce the size of the response when many fields have null values.
To enable this globally for all responses you can set RPCManager.omitNullMapValuesInResponse in server.properties.
Note : This is an advanced setting

Parameters:

omitNullMapValuesInResponse - Default value is false

getOmitNullMapValuesInResponse
```
public java.lang.Boolean getOmitNullMapValuesInResponse()
```
If enabled, the server omits any key/value pairs in map that have null values from the response. This can reduce the size of the response when many fields have null values.
To enable this globally for all responses you can set RPCManager.omitNullMapValuesInResponse in server.properties.

Returns:

Boolean

setParams
```
public void setParams(java.util.Map params)
```
Values to be sent as simple HTTP params, as a JavaScript Object where each property/value pair will become an HTTP parameter name and value. These parameters are then accessible on the server, for example, using servletRequest.getParameter(paramName) in Java Servlets.
Array-valued parameters will be submitted as multiple instances of the same parameter, similar to an HTML form with a multi-select (?paramName=value1&paramName=value2 ...), accessible as getParameterValues(paramName) in Java Servlets. Any non-atomic type, such as an Object, will be serialized to JSON by the JSONEncoder. If this isn't desirable, serialize the data in advance so that the value provided in rpcRequest.params is a String.
Note that this API is primarily used in combination with useSimpleHttp - when contacting the Smart GWT Server, use data instead, which provides full JavaScript <-> Java translation of arbitrary structures. rpcRequest.params can also be used with the Smart GWT Server, where it provides an an opportunity to send additional data aside from the main data payload. This is useful for adding data to DataSource requests which will be kept separate from the automatically sent DataSource data, or for making parts of the request visible in the URL for HTTP-level logging or layer 4 switches.
Note that in contrast to data object, the data in rpcRequest.params is not deserialized by the Smart GWT server, and all values arrive on the server as String type (like HTTP parameters always do).

Note: The params are submitted once per http transaction. If you are using request queuing to bundle multiple RPCRequests or DSRequests into a single HTTP turnaround, the params from the various RPCRequests will be merged, with the later-queued transactions winning on parameter name collisions. A warning will be logged in the Developer Console if multiple RPCRequests specified params.

Parameters:

params - Default value is null

getParams
```

setSendNoQueue
```
public void setSendNoQueue(java.lang.Boolean sendNoQueue)
```
When set to true, this request is sent to the server immediately, bypassing any current queue.
Note : This is an advanced setting

Parameters:

sendNoQueue - Default value is false

getSendNoQueue
```
public java.lang.Boolean getSendNoQueue()
```
When set to true, this request is sent to the server immediately, bypassing any current queue.

Returns:

Boolean

setServerOutputAsString
```
public void setServerOutputAsString(java.lang.Boolean serverOutputAsString)
```
Setting this flag makes the body of the HTTP response available as a String in the callback as RPCResponse.data. This is typically only useful if you are sending a request that will not be received by the Smart GWT Java Server, however in that case, set useSimpleHttp:true instead, which implies serverOutputAsString:true.
serverOutputAsString:true allows you to, for example, load the contents of static files off your webserver into a string for processing on the client with no server support. The actionURL must be in the same domain as the current page for this to work.
This feature relies on the XMLHttpRequest object which can be disabled by end-users in some supported browsers. See PlatformDependencies for more information.
Generally this API is used for either non-Java backends or for advanced usage such as content that requires processing before it can be used in Smart GWT components (such as client-side web scraping). Note that Smart GWT provides higher-level APIs for loading common types of data, see eg HTMLFlow for HTML content, ViewLoader for loading Smart GWT components, XMLTools.loadXML() for loading XML, evalResult for loading JSON, and DataSource for loading structured data in various formats.
Note : This is an advanced setting

Parameters:

serverOutputAsString - Default value is false

getServerOutputAsString

Returns:

Boolean

setShowPrompt
```
public void setShowPrompt(java.lang.Boolean showPrompt)
```
Overrides RPCManager.showPrompt for this request only.
If you're using queuing, note that if any of the requests in the queue specify showPrompt:true, then a prompt will be shown for the entire queue with the prompt text of the first request in the queue to specify a custom prompt if promptStyle is set to "dialog".
If promptStyle is set to "cursor" for the request that specified showPrompt: true, then the entire queue uses the "cursor" style for the prompt.

Parameters:

showPrompt - Default value is null

See Also:

com.smartgwt.client.rpc.RPCManager#showPrompt, RpcPrompt overview and related methods

getShowPrompt
```
public java.lang.Boolean getShowPrompt()
```
Overrides RPCManager.showPrompt for this request only.
If you're using queuing, note that if any of the requests in the queue specify showPrompt:true, then a prompt will be shown for the entire queue with the prompt text of the first request in the queue to specify a custom prompt if promptStyle is set to "dialog".
If promptStyle is set to "cursor" for the request that specified showPrompt: true, then the entire queue uses the "cursor" style for the prompt.

Returns:

Boolean

See Also:

setSuppressAutoDraw
```
public void setSuppressAutoDraw(java.lang.Boolean suppressAutoDraw)
```
If evalResult is set, setting this property to true causes Canvas.autoDraw to be set to false for the duration of the result evaluation - which is generally what you want if you're returning new components from the server.
This also effects components loaded via the RPCManager.loadScreen() API.
Note : This is an advanced setting

Parameters:

suppressAutoDraw - Default value is true

getSuppressAutoDraw
```
public java.lang.Boolean getSuppressAutoDraw()
```
If evalResult is set, setting this property to true causes Canvas.autoDraw to be set to false for the duration of the result evaluation - which is generally what you want if you're returning new components from the server.
This also effects components loaded via the RPCManager.loadScreen() API.

Returns:

Boolean

setTimeout
```
public void setTimeout(java.lang.Integer timeout)
```
Sets the timeout on this request. Default is to use defaultTimeout.
If you're using queuing, note that the timeout setting derived from the last request in the queue is used for the entire queue. If you want to override the timeout for the queue, make sure to set your override at least on the last request in the queue.
For the "xmlHttpRequest" transport, this timeout can only happen if the server actually fails to respond within the specified number of milliseconds. For the "hiddenFrame" transport, this timeout will occur for non-200 (HTTP_OK) responses.
If timeout is set to zero, the RPCManager will not enforce a timeout for this request. However, note that all browsers enforce their own timeouts on HTTP requests, and may have different timeouts for different kinds of failures (no response at all from server, hung response after receiving headers, hung response after receiving partial data, etc). Also, intervening web proxies or firewalls may impose timeouts of their own.
As a rough rule of thumb, if your server response will have a lengthy pause before data begins to be sent, 1-2 minutes is the maximum allowable pause for a public site and still may not work for a minority of users, but up to 4 minutes may be allowable in a controlled environment (intranet or extranet with well-known user base).
Above these limits, your code should return some kind of immediate response to the browser, then kick off a server-side process to complete processing. The browser can then either poll for completion, or use a server-push notification system such as Smart GWT Real-Time Messaging (see http://smartclient.com/product).
Note : This is an advanced setting

Parameters:

timeout - Default value is null

See Also:

com.smartgwt.client.rpc.RPCManager#defaultTimeout

getTimeout
```
public java.lang.Integer getTimeout()
```
Sets the timeout on this request. Default is to use defaultTimeout.

setTransport
```
public void setTransport(RPCTransport transport)
```
Selects the transport used for this RPCRequest. If unset, the value of defaultTransport will be used.
If you're using queueing, note that all requests in the queue must use the same transport. If you attempt to send a request via a different transport than those that are currently on the queue, it will be sent to the server separately, ahead of the queue, and a warning will be logged to the Developer Console.
If you specify an unknown transport, an error will be logged to the DeveloperConsole and defaultTransport will be used instead.
If you specify the xmlHttpRequest transport and it is not available, a warning will be logged to the Developer Console and the RPCManager will attempt to use the hiddenFrame transport instead for this request. Note that some features like serverOutputAsString require the xmlHttpRequest transport and will not work if the xmlHttpRequest transport is unavailable (this can happen if the end user is using Internet Explorer and has disabled ActiveX). You can check whether or not the xmlHttpRequest transport is currently available by calling RPCManager.xmlHttpRequestAvailable().
Note : This is an advanced setting

Parameters:

transport - Default value is RPCManager.defaultTransport

See Also:

com.smartgwt.client.rpc.RPCManager#defaultTransport

getTransport
```
public RPCTransport getTransport()
```

setUseHttpProxy
```
public void setUseHttpProxy(java.lang.Boolean useHttpProxy)
```
Indicates whether this request should use the HttpProxyServlet in order to enable contacting hosts other than the origin server (available only in Pro Edition or better).
When various UI components issues requests automatically, or when a call to RPCManager.sendProxied() is made, the HttpProxy will automatically be used for a URL that starts with "http" and uses a hostname other than "localhost" or window.location.hostname, or if the port number differs.
rpcRequest.useHttpProxy should only be used to force requests to go through the HttpProxy when the above rules don't work, or to avoid using the HttpProxy when contacting hosts that allow cross-site calls via the Http Access Control standard.
You can also set useHttpProxy:false to avoid ever using the HttpProxyServlet.

Parameters:

useHttpProxy - Default value is null

getUseHttpProxy
```
public java.lang.Boolean getUseHttpProxy()
```
Indicates whether this request should use the HttpProxyServlet in order to enable contacting hosts other than the origin server (available only in Pro Edition or better).
When various UI components issues requests automatically, or when a call to RPCManager.sendProxied() is made, the HttpProxy will automatically be used for a URL that starts with "http" and uses a hostname other than "localhost" or window.location.hostname, or if the port number differs.

You can also set useHttpProxy:false to avoid ever using the HttpProxyServlet.

Returns:

Boolean

setUseSimpleHttp
```
public void setUseSimpleHttp(java.lang.Boolean useSimpleHttp)
```
When set to true, assume the request is not going to the Smart GWT server, and hence send a simple HTTP request that does not use Smart GWT-specific request encoding.
Values specified in params are sent to to the server as HTTP request parameters. If httpMethod is "GET", parameters appear in the request URL, otherwise if httpMethod is "POST", parameters are encoded in the request body (exactly like an HTML form does). These parameters are then accessible via typical server-side APIs for retrieving HTTP parameters, eg, servletRequest.getParameter(paramName) in Java Servlets.
Note that if httpMethod method is POST and data is supplied, data is assumed to be a string to post as the HTTP request body, and params are sent as URL parameters instead. This usage is for sending custom request bodies such as the XML payloads used for SOAP. In this case, contentType is typically also set to indicate the content type of the request body.
Setting useSimpleHttp to true also automatically sets serverOutputAsString to true as well.
Note : This is an advanced setting

Parameters:

useSimpleHttp - Default value is false

getUseSimpleHttp
```
public java.lang.Boolean getUseSimpleHttp()
```

setWillHandleError
```
public void setWillHandleError(java.lang.Boolean willHandleError)
```
With willHandleError:false, rpcResponses that indicate an error go through centralized handling in the RPCManager and rpcRequest.callback is never invoked.
Setting willHandleError:true means that your rpcRequest.callback will receive rpcResponses that have an error status and must handle them.
See also the error handling section in the RPCManager docs.

Parameters:

willHandleError - Default value is false

See Also:

RPCManager, ErrorHandling overview and related methods

getWillHandleError
```
public java.lang.Boolean getWillHandleError()
```

setWithCredentials
```
public void setWithCredentials(java.lang.Boolean withCredentials)
```
In browsers that support Cross-Origin Resource Sharing and XMLHttpRequest 2, and where the service at the actionURL allows the origin to send credentials (see Access-Control-Allow-Credentials), should user credentials such as cookies, HTTP authentication, and client-side SSL certificates be sent with the actual CORS request?
This setting only applies when the request transport is RPCTransport.XMLHTTPREQUEST.
Note that Internet Explorer 10 and 11 do not send cookies as part of user credentials: IE10 doesn't support cookies on cross origin XMLHttpRequest withCredentials=true.
Note : This is an advanced setting

Parameters:

withCredentials - Default value is null

getWithCredentials
```
public java.lang.Boolean getWithCredentials()
```
In browsers that support Cross-Origin Resource Sharing and XMLHttpRequest 2, and where the service at the actionURL allows the origin to send credentials (see Access-Control-Allow-Credentials), should user credentials such as cookies, HTTP authentication, and client-side SSL certificates be sent with the actual CORS request?
This setting only applies when the request transport is RPCTransport.XMLHTTPREQUEST.
Note that Internet Explorer 10 and 11 do not send cookies as part of user credentials: IE10 doesn't support cookies on cross origin XMLHttpRequest withCredentials=true.

Returns:

Boolean

create
```
public static void create()
```
RPCRequest shouldn't be created directly. Instead, pass Properties to RPCManager.sendRequest() and RPCManager.send().

setData

public void setData(com.google.gwt.core.client.JavaScriptObject data)

If the client side request.data is set to a Java object in your SmartGWT code on the client side, logic in your server side code will be passed the following equivalent objects:

Client	Server Type
boolean primitive or Boolean	Boolean
Non-fractional numeric value (e.g: int, Integer, long, Long)	Long
Fractional numeric value (e.g:float, Float, double, Double)	Double
String	String
Date	Date
List, Set, Iterator	List
Map	Map
Record	Map
RecordList	List of Map
ResultSet	List of Map (containing only loaded rows if the ResultSet has a partial cache on the client)

Note that the order of keys/values in the Maps created on the server is not guaranteed because JavaScript Object literals do not guarantee order.

Server->client conversion follows this table as well, with some extras. See the toJS() method on JSTranslater in the server documentation for a description of additional behaviors.

When not communicating with the Smart GWT server, rpcRequest.data becomes simple HTTP parameters or an HTTP request body - see useSimpleHttp for details.

Parameters:: data - data Default value is null
See Also:: RPCResponse.getDataAsMap(), RPCResponse.getDataAsObject(), RPCResponse.getDataAsString()

getData

public com.google.gwt.core.client.JavaScriptObject getData()

Returns the payload of this request to be sent to the server, as a JavaScriptObject.

When using the Smart GWT server, objects sent to the server as request.data will be available on the server-side RPCRequest object as Java Objects. This is achieved by serializing the client side data in a JSON type format and generating Java Objects on the server from this serialized data.

If the client side request.data is set to a Java object in your SmartGWT code on the client side, logic in your server side code will be passed the following equivalent objects:

Client	Server Type
boolean primitive or Boolean	Boolean
Non-fractional numeric value (e.g: int, Integer, long, Long)	Long
Fractional numeric value (e.g:float, Float, double, Double)	Double
String	String
Date	Date
List, Set, Iterator	List
Map	Map
Record	Map
RecordList	List of Map
ResultSet	List of Map (containing only loaded rows if the ResultSet has a partial cache on the client)
