public OperationBinding setDataProtocol(DSProtocol dataProtocol)
When a DataSource operation such as fetchData() is
invoked on this DataSource or a component bound to this DataSource, the data passed to the operation, if any, will be
sent to the dataURL
. The dataProtocol
property controls the format in which the data is sent:
SOAP message, HTTP GET or POST of parameters, etc.
The dataProtocol
property need not be set for a
DataSource with a WebService ( DataSource.serviceNamespace
is set), in this case, SOAP messaging is used by default.
Developers may completely
bypass the Smart GWT comm system by setting dataProtocol to "clientCustom"
. In this case Smart GWT will not
attempt to send any data to the server after calling DataSource.transformRequest()
. Instead the developer is expected to implement transformRequest()
such that
it performs the necessary data action outside of Smart GWT, and then calls DataSource.processResponse()
, passing in the DSRequest.requestId
and an appropriate set of DSResponse properties to
indicate the result of the action.
NOTE: when dataFormat
is "iscServer", dataProtocol
is not consulted. Instead, Smart GWT uses a proprietary wire
format to communicate with the Smart GWT server, and the server-side DSRequest and DSResponse objects should be used to
access request data and form responses.

You can also configure the style of line-breaks to use when generating the output. See

Additionally, custom server code may set export-related properties on the

public OperationBinding setRecordXPath(java.lang.String recordXPath)
For example, an "ItemSearch" web service might return a "Results" structure containing metadata along with the set of Items that one might want to display in a grid. An XPath expression like "/Results/Items" could be used to retrieve just the Items, which would then become DataSource records.
For a JSON web service, the recordXPath
is
applied to the returned JSON data via XMLTools.selectObjects()
.
Only limited XPath syntax is allowed; see selectObjects()
for
details.
For processing XML results, see xmlNamespaces
for information on the namespaces that are available in this XPath expression. If you are contacting a
WSDL web service, note that recordName
is an alternative
way to specify which records should be selected by their tagName or type, and this is usually simpler.

this flag means the DataSource doesn't actually attempt to contact the server but generates a sample response instead,
based on the XML Schema of the response message embedded in the WSDL. The spoofed response will include all complexType elements and will fill in appropriate values by type for all simpleType elements, although the spoofed data will not conform to all xs:restriction declarations (eg xs:pattern).
Note that if your WSDL does not fully describe
the response format (some WSDL services just have a placeholder <xs:any> element), Smart GWT can only produce a
partial response. To use a hand-generated sample response, just save an XML file to disk and use the dataURL
setting to point to it.

public OperationBinding setUseFlatFields(boolean useFlatFields)
useFlatFields
on an operationBinding is equivalent to setting DSRequest.useFlatFields
on all DataSource requests with the same
operationType
as this operationBinding
.
Typical usage is to combine operationBinding.useFlatFields with searchForm.useFlatFields
, with the SearchForm
bound to the input
message
of the web service operation set as wsOperation
. This allows gratuitous nesting to be consistently bypassed in both the user presentation and in the
actual XML messaging.
Note that useFlatFields
is not generally recommended for use with input messages
where multiple simple type fields exist with the same name, however if used in this way, the first field to use a given
name wins. "first" means the first field encountered in a depth first search. "wins" means only the first field will
be available in data binding, and only the first field will be populated in the generated XML message.

public OperationBinding setWsOperation(java.lang.String wsOperation)
Valid only for
a DataSource that has a WebService (DataSource.serviceNamespace
is set). Otherwise, use dataURL
.
Setting wsOperation
means that DSRequest.data
will be serialized as the request message for the specified web service operation, with namespacing and
soap encoding handled automatically. See DataSource.transformRequest()
for how to customize what data is sent to the server.

public OperationBinding setXmlNamespaces(XmlNamespaces xmlNamespaces)
recordXPath
and
DataSourceField.valueXPath
XPath expressions.
xmlNamespaces
should be specified as a mapping from namespace prefix to
namespace URI, for example:
xmlNamespaces : { az : "http://webservices.amazon.com/AWSECommerceService/2005-03-23" }By default, all namespaces declared on the document element (outermost element of the response) are made available with the prefix used in the document itself.
Then, for non-WSDL-described XML results, if there is a default namespace on the document element, it is made available with the special prefix "default".
For results of WSDL-described operations, the prefix "service" means the service namespace, that is, the "targetNamespace" on the <definitions> element from the WSDL file. The prefix "schema" means the namespace of the outermost element in the output message for the current operation. "default" will be the schema namespace if there is one, otherwise the service namespace.
