public class MessageDispatcherServlet
extends FrameworkServlet

Servlet for simplified dispatching of Web service messages.

This servlet is a convenient alternative to the standard Spring-MVC DispatcherServlet with separate WebServiceMessageReceiverHandlerAdapter, MessageDispatcher, and WsdlDefinitionHandlerAdapter instances.

This servlet automatically detects EndpointAdapters, EndpointMappings, and EndpointExceptionResolvers by type.

This servlet also automatically detects any WsdlDefinition defined in its application context. This WSDL is exposed under the bean name: for example, a WsdlDefinition bean named 'echo' will be exposed as echo.wsdl in this servlet's context: http://localhost:8080/spring-ws/echo.wsdl. When the transformWsdlLocations init-param is set to true in this servlet's configuration in web.xml, all location attributes in the WSDL definitions will reflect the URL of the incoming request.

Since:

1.0.0
