public class WebServiceTemplate
extends WebServiceAccessor
implements WebServiceOperations

The central class for client-side Web services. It provides a message-driven approach to sending and receiving WebServiceMessage instances.

Code using this class need only implement callback interfaces, provide Source objects to read data from, or use the pluggable Marshaller support. For invoking the marshalling methods, the marshaller and unmarshaller properties must be set.

This template uses a SoapFaultMessageResolver to handle fault response messages. Another FaultMessageResolver can be defined with with faultMessageResolver property. If this property is set to null, no fault resolving is performed.

This template uses the following algorithm for sending and receiving.

1. Call createConnection().
2. Call createWebServiceMessage() on the registered message factory to create a request message.
3. Invoke doWithMessage() on the request callback, if any. This step stores content in the request message, based on Source, marshalling, etc.
4. Invoke handleRequest() on the registered interceptors. Interceptors are executed in order. If any of the interceptors creates a response message in the message context, skip to step 7.
5. Call send() on the connection.
6. Call hasError() to check if the connection has an error. For an HTTP transport, a status code other than 2xx indicates an error. However, since a status code of 500 can also indicate a SOAP fault, the template verifies whether the error is not a fault.
• If the connection has an error, call the handleError() method, which by default throws a WebServiceTransportException.
• If the connection has no error, continue with the next step.
7. Invoke receive on the connection to read the response message, if any.
• If no response was received, return null or false
• Call hasFault() to determine whether the response has a fault. If it has, call ClientInterceptor.handleFault(MessageContext) and the handleFault() method.
• Otherwise, invoke ClientInterceptor.handleResponse(MessageContext) and extractData() on the response extractor, or doWithMessage on the response callback.
8. Call to close on the connection.

getMarshaller

public org.springframework.oxm.Marshaller getMarshaller()

Returns the marshaller for this template.

setMarshaller

public void setMarshaller(org.springframework.oxm.Marshaller marshaller)

setUnmarshaller

public void setUnmarshaller(org.springframework.oxm.Unmarshaller unmarshaller)

getFaultMessageResolver

public FaultMessageResolver getFaultMessageResolver()

Returns the fault message resolver for this template.

setFaultMessageResolver

public void setFaultMessageResolver(FaultMessageResolver faultMessageResolver)

Sets the fault resolver for this template. Default is the SoapFaultMessageResolver, but may be set to null to disable fault handling.

setCheckConnectionForError

public void setCheckConnectionForError(boolean checkConnectionForError)

Indicates whether the connection should be checked for error indicators (true), or whether these should be ignored (false). The default is true.

When using an HTTP transport, this property defines whether to check the HTTP response status code is in the 2xx Successful range. Both the SOAP specification and the WS-I Basic Profile define that a Web service must return a "200 OK" or "202 Accepted" HTTP status code for a normal response. Setting this property to false allows this template to deal with non-conforming services.

See Also:

• hasError(WebServiceConnection, WebServiceMessage)
• SOAP 1.1 specification
• WS-I Basic Profile

setCheckConnectionForFault

public void setCheckConnectionForFault(boolean checkConnectionForFault)

Indicates whether the connection should be checked for fault indicators (true), or whether we should rely on the message only (false). The default is true.

When using an HTTP transport, this property defines whether to check the HTTP response status code for fault indicators. Both the SOAP specification and the WS-I Basic Profile define that a Web service must return a "500 Internal Server Error" HTTP status code if the response envelope is a Fault. Setting this property to false allows this template to deal with non-conforming services.

See Also:

• hasFault(WebServiceConnection,WebServiceMessage)
• SOAP 1.1 specification
