Interceptor for JBossWS

[pramod_bs]

How I can write an Interceptor for a web service. Here is the scenario:
I have a service with WS-Security. After the JBossWS authenticated the user I need to intercept for applying policy using XACML. Ay ideas will be greatly appreciated.

Did you already take a look at the handler documentation? http://jbws.dyndns.org/mediawiki/index.php?title=JAX-WS_User_Guide#Handler_Framework

I looked at the doc. I might have got lost. My confusion is how to include my XACML policy validation inside the handler chain after JBossWS handles the username token authentication. Or is there another better way of handling this?
