The Web services handler, which is built from the JAX-WS technology, is a message interceptor that can be used at JAX-WS runtime by the Web services connector to enhance the processing and transmission of messages between a WebSphere® Multichannel Bank Transformation Toolkit application and Web services. Because JAX-PRC does not have a mechanism for message interception, WebSphere Multichannel Bank Transformation Toolkit provides the JaxRpcServiceProcessor as well as the Web services handler.
