Class WsdlDefinitionHandlerAdapter

java.lang.Object
  extended by org.springframework.xml.transform.TransformerObjectSupport
      extended by org.springframework.ws.transport.http.LocationTransformerObjectSupport
          extended by org.springframework.ws.transport.http.WsdlDefinitionHandlerAdapter
All Implemented Interfaces:
InitializingBean, HandlerAdapter

public class WsdlDefinitionHandlerAdapter
extends LocationTransformerObjectSupport
implements HandlerAdapter, InitializingBean

Adapter to use the WsdlDefinition interface with the generic DispatcherServlet.

Reads the source from the mapped WsdlDefinition implementation, and writes that as the result to the HttpServletResponse.

If the property transformLocations is set to true, this adapter will change location attributes in the WSDL definition to reflect the URL of the incoming request. If the location field in the original WSDL is an absolute path, the scheme, hostname, and port will be changed. If the location is a relative path, the scheme, hostname, port, and context path will be prepended. This behavior can be customized by overriding the transformLocation() method.

For instance, if the location attribute defined in the WSDL is http://localhost:8080/context/services/myService, and the request URI for the WSDL is http://example.com/context/myService.wsdl, the location will be changed to http://example.com/context/services/myService.

If the location attribute defined in the WSDL is /services/myService, and the request URI for the WSDL is http://example.com:8080/context/myService.wsdl, the location will be changed to http://example.com:8080/context/services/myService.

When transformLocations is enabled, all location attributes found in the WSDL definition are changed by default. This behavior can be customized by changing the locationExpression property, which is an XPath expression that matches the attributes to change.

                           throws Exception
Transforms all location attributes to reflect the server name given HttpServletRequest. Determines the suitable attributes by evaluating the defined XPath expression, and delegates to transformLocation to do the transformation for all attributes that match.

This method is only called when the transformLocations property is true.

Throws:
Exception
