public class WebService
extends BaseClass

Class representing a WebService definition derived from a WSDL file.

A Web Service object allows you to invoke operations (via callOperation()), inspect schema declared in the WSDL file (getSchema()), and perform simple read-only databinding getFetchDS().

Once a WebService has been loaded, a DataSource can be declared with a serviceNamespace to connect it to the web service, allowing DataSource data to be loaded and saved to the web service using operationBindings.

callOperation

public void callOperation(java.lang.String operationName,
                          java.util.Map paramData,
                          java.lang.String resultType,
                          WebServiceCallback callback)

Invoke a web service operation.

The data parameter will be serialized to XML to form the input message for
the operation, as described by ${isc.DocUtils.linkForRef('method:DataSource.xmlSerialize')}. Namespacing,
element ordering, and SOAP encoding rules are automatically followed. If the web
service you are trying to contact requires a complicated nested structure, consider
using WSRequest.setUseFlatFields(Boolean) to simplify the required JavaScript input data.

The resultType selects what part of the message should be decoded to
JavaScript and made available as the "data" variable in the callback. The
resultType parameter can be either:

• an XPath. "data" will be always be an Array, containing the selected elements as
  decoded by XMLTools.toJS. All properties will have String value.
  
• the name of an XML Schema type found somewhere in the response. You can use the
  WSDL tab of the Developer Console to analyze the WSDL file for an appropriate type name.
  "data" will be an Array, containing the decoded elements as decoded by
  DataSource.recordsFromXML(Object) . In this case, since the XML Schema type of the
  selected data is known, properties will have correct type (eg "date" fields will
  have JavaScript Date objects)
  
• null. "data" will an Object representing the entire <SOAP:Body> as decoded
  to JavaScript. As above, properties will have correct type.
  

In the callback, you also receive the XML document returned by the web service as
"xmlDoc".

NOTE: callOperation() is appropriate for simple operations that do not
involve DataBound Components, such as logging into a web service, or retrieving simple
String data. callOperation() can also be used to retrieve small, read-only
datasets such as the option list for a SelectItem, but only if the dataset is guaranteed
to remain small enough for paging to be unnecessary. For any larger datasets or
anything that will be edited, DataSource integration is more appropriate.

Parameters:

operationName - Name of the operation to invoke

paramData - data to serialize as XML to form the inbound message of the operation

resultType - Type, Element name, or XPath that should be selected from the result

callback - Callback to invoke on completion

paramData - data to serialize as XML to form the inbound message of the operation

resultType - Type, Element name, or XPath that should be selected from the result

callback - Callback to invoke on completion

wsRequestProperties - Additional properties for the WSRequest, such as HTTPHeaders

setLocation

public void setLocation(java.lang.String url)

Set location can be used when the actual URL where a service will be accessible isn't known until runtime, or changes at runtime, hence can't be embedded in the service definition.
With an operation parameter, setLocation() can be used to set a distinct URL for each web service operation. This is a development-time only feature that allows XML flat files to be placed at various URLs on a server, to serve as spoofed responses for each web service operation.

Parameters:

url - the URL where web service can be contacted

setLocation

public void setLocation(java.lang.String url,
                        java.lang.String operation)

Set location can be used when the actual URL where a service will be accessible isn't known until runtime, or changes at runtime, hence can't be embedded in the service definition.
With an operation parameter, setLocation() can be used to set a distinct URL for each web service operation. This is a development-time only feature that allows XML flat files to be placed at various URLs on a server, to serve as spoofed responses for each web service operation.

Parameters:

url - the URL where web service can be contacted

operation - optional operation name to set the location for, for debugging only

getInputDS

public DataSource getInputDS(java.lang.String operationName)

Get a DataSource representing the input message to a web service operation. This DataSource is suitable for use as form.dataSource for a form that the user fills out when providing inputs to call this web service operation.

Parameters:

operationName - name of the web service operation whose inputs the returned DataSource will represent

Returns:

DataSource representing the input message of a web service operation

getFetchDS

public DataSource getFetchDS(java.lang.String operationName,
                             java.lang.String resultType)

Retrieve a DataSource that provides read-only access to records returned by a web service operation.
DataBound Components can be bound to the returned DataSource, and the fetchData() method can be invoked to retrieve data from the web service.
The returned DataSource is only capable of the "fetch" DataSource operation, not "update", "add" or "remove". To create a DataSource capable of full read-write access, use DataSource.operationBindings with the wsOperation property set to associate each DataSource operation with a web service operation.

Parameters:

operationName - name of the web service operation to invoke to fetch records

resultType - tag or type name of the XML element to be returned as DataSource records

Returns:

dDataSource representing the fetch message of a web service operation

getFetchDS

public DataSource getFetchDS(java.lang.String operationName,
                             java.lang.String resultType,
                             OperationBinding operationBindingProperties)

Retrieve a DataSource that provides read-only access to records returned by a web service operation.
DataBound Components can be bound to the returned DataSource, and the fetchData() method can be invoked to retrieve data from the web service.
The returned DataSource is only capable of the "fetch" DataSource operation, not "update", "add" or "remove". To create a DataSource capable of full read-write access, use DataSource.operationBindings with the wsOperation property set to associate each DataSource operation with a web service operation.

Parameters:

operationName - name of the web service operation to invoke to fetch records

resultType - tag or type name of the XML element to be returned as DataSource records

operationBindingProperties - additional properties for the operationType:"fetch" operationBinding which this method automatically creates. This can be used to set properties such as com.smartgwt.client.data.OperationBinding#setUseFlatFields(Boolean) or OperationBinding.setRecordXPath(String)

Returns:

dDataSource representing the fetch message of a web service operation

getSchema

public DataSource getSchema(java.lang.String schemaName)

Get the schema definition of any complexType or element of complexType defined in any blocks in the WSDL file this WebService represents.

Parameters:

schemaName - name of type or element

Returns:

requested schema

getSchema

public DataSource getSchema(java.lang.String schemaName,
                            java.lang.String schemaType)

Get the schema definition of any complexType or element of complexType defined in any blocks in the WSDL file this WebService represents.

Parameters:

schemaName - name of type or element

schemaType - optional type of schema to return, either "element" for xs:element definitions only or "type" for xs:complexType definitions. If unspecified, either will be returned, with types preferred if names collide

Returns:

requested schema

get

public static WebService get(java.lang.String serviceNamespace)

Retrieve a WebService object by the targetNamespace declared on the element in the WSDL file from which the WebService was derived.

Parameters:

serviceNamespace - uri from the "targetNamespace" attribute of the element in the WSDL file

Returns:

the requested WebService, or null if not loaded

getSoapMessage

public java.lang.String getSoapMessage(WSRequest wsRequestProperties)

Return the SOAP message that will be formed from this WSRequest.

Parameters:

web - service request object

Returns:

SOAP message
