Previously, Teiid was running in its own VM, so we provided custom web service client code using the JAX-WS "Dispatch" interface and Axis2's Call interface to invoke the web-service calls along with Teiid's own configuration.

In this environment, we feel it is probably verbose for us to provide yet another way to configure web-service client. We want to use any predefined methods that are in work through JBossWS project.

Dispatch is perfect, but all examples show them how to use in the code, not through configuration. We are willing to extend any technique to fit our needs. Any advise for us?

JBossWS implements JAX-WS API, hence that's what you should be using. Speaking of client side, yes dispatch is probably the solution that gives you better flexibility, as you basically send the xml message you want. Besides that, there're jbossws specific configurations for advanced things like ws-security, mtom, ... you should refer to the documentation for that ( http://community.jboss.org/wiki/JBossWS http://community.jboss.org/wiki/JBossWS)
I might be missing the real point here, but if you're looking for "predefined", "smart", "different" ways for defining a client, you might want to look at what JBoss ESB does. Also JBoss Wise might be interesting to you, given its facilities for simplified jaxws client programming.
DocLit vs Wrapped is not a problem at all, supported by JBossWS implementation.
JAX-RPC is implemented by JBossWS-Native and available with CXF and Metro based stack starting from AS 6 M3.
REST is out of scope for JBossWS, you should refer to RestEasy project.
