Dynamic and static clients

The dynamic client programming API for JAX-WS is called the dispatch client (javax.xml.ws.Dispatch). The dispatch client is an XML messaging oriented client. The data is sent in either PAYLOAD or MESSAGE mode:

PAYLOAD: When using the PAYLOAD mode, the dispatch client is only responsible for providing the contents of the <soap:Body> element and JAX-WS adds the <soap:Envelope> and <soap:Header> elements.

MESSAGE: When using the MESSAGE mode, the dispatch client is responsible for providing the entire SOAP envelope including the <soap:Envelope>, <soap:Header>, and <soap:Body> elements and JAX-WS does not add anything additional to the message. The dispatch client supports asynchronous invocations using a callback or polling mechanism.

The static client programming model for JAX-WS is the called the proxy client. The proxy client invokes a Web service based on a service endpoint interface (SEI) which is generated or provided.
