Setting Up a Handler
To create and implement a handler, you need to:
1. Build the services for handling a request, handling a response, and handling a fault. Use the pub.soap.handler:handlerSpec specification as the signature for a service that acts as a header handler.
2. Register the combination of those services as a header handler. For more information, see Registering a Handler.
3. Assign the header handler to the web service descriptor. For more information, see webMethods Service Development Help.
