A JAX-WS handler is a Java™ class that performs a range of handling tasks. For example: logging messages, or transforming their contents, or terminating an incoming request. You can create JAX-WS handlers, chain them together in the form of a handler list, then apply the handler list to a Version 7.0 WS-Notification service point (for inbound invocation handling) or WS-Notification service (for outbound invocation handling).
The Java API for XML-based Web Services (JAX-WS) provides you with a standard way of developing interoperable and portable web services. To create a JAX-WS handler, you can use a tool such as IBM® Rational® Application Developer. To enable handlers to undertake more complex operations, you chain them together into handler lists. You associate each handler list with one or more Version 7.0 WS-Notification services or service points, so that the handler list can monitor WS-Notification activity and take appropriate action depending upon the sender and content of each inbound or outbound message.
Detailed instructions on how to configure JAX-WS handlers and handler lists for use with Version 7.0 WS-Notification services are provided in the following topics:
A JAX-WS handler interacts with messages through a Version 7.0 WS-Notification service point (for inbound invocation handling) or WS-Notification service (for outbound invocation handling), therefore you must make the handler class available to the server or cluster that hosts the WS-Notification service point or service that you want to monitor.
