That would be ideal, but the way Eclipse WTP framework works and is being used it is not possible for the
AS runtime to know which jars from the runtime it should expose or not.

JPA, WS and JSF is something commonly provided by the runtime in j2EE, Seam and other frameworks are not. They are bundled with the app.

Suggestions welcome ;)
