WS client and service endpoints are fundamentally disconnected. To provide a WS4EE service endpoint on JBoss is one ball game. Connecting from a WS4EE client to an external web service is another. Both parties should not care what technology the other uses.

1) yes

2ab) only if it is a WS4EE client running on JBoss
