Provider Services

Messaging Modes

Overview

Objects that implement the Provider interface have two messaging modes:

• Message mode
• Payload mode

The messaging mode you specify determines the level of messaging detail that is passed to your implementation.

Message mode

When using message mode, a Provider implementation works with complete messages. A complete message includes any binding specific headers and wrappers. For example, a Provider implementation that uses a SOAP binding would receive requests as fully specified SOAP message. Any response returned from the implementation would also need to be a fully specified SOAP message.

You specify that a Provider implementation uses message mode by providing the value java.xml.ws.Service.Mode.MESSAGE as the value to the javax.xml.ws.ServiceMode annotation.

@WebServiceProvider
@ServiceMode(value=Service.Mode.MESSAGE)
public class stockQuoteProvider implements Provider<SOAPMessage>
{
  ...
}

Payload mode

In payload mode a Provider implementation works with only the payload of a message. For example, a Provider implementation working in payload mode works only with the body of a SOAP message. The binding layer processes any binding level wrappers and headers.

You specify that a Provider implementation uses payload mode by providing the value java.xml.ws.Service.Mode.PAYLOAD as the value to the javax.xml.ws.ServiceMode annotation.

@WebServiceProvider
@ServiceMode(value=Service.Mode.PAYLOAD)
public class stockQuoteProvider implements Provider<DOMSource>
{
  ...
}
