JAR / WAR / EAR中的MessageHandler

Question

I am making a PEP Server which intercepts the SOAP messages, and checks them against WS-Policies defined in a separate database. It is divided in 3 compontents:

1) PEP (Policy enforcemenet point) intercepts the messages with a message handler

2) sends it to the -> PDP (Policy decision point) decides which message gets through

3) this by using the PIP (Policy information point) which has a database with the policies.

If the policies are correct, the message gets send further to the web service. Now I was wondering how it would be possible to package this PEP in a JAR file (or WAR/EAR? I am new to this so I am not sure in which kind of package it should come). The PEP is a messagehandler, so the Web service will have to specify a @HandlerChain(file = "handler.xml")

Would it now be possible to include this PEP in the xml file, if its in contained in a jar file?

I recommend using JAX-WS for creating and invoking Java Web Services.

There's a nice tutorial about creating both a service and a client to invoke the service. In your case, you'd want to zero in on the "A Simple JAX-WS Client" section. They outline how to do this with NetBeans but you can get the general idea and then revamp for your particular situation.

Here's the link for the tutorial: Creating a Simple Web Service and Client with JAX-WS

I'm thinking in your situation that you can just create a Java client that gets packaged as a JAR.
