I advise against creating Java client stubs from Java server artifacts
because they make a tight coupling between client and server-side code
(but see later).

Human readable documentation of the service to be read by the
developer. Because the client is separated from the server you can
also do:
wr = client.resource("
http://localhost:8080/pe-backend/resources/activities
");
activityArray = wr.get(Activity[].class);
or perhaps use a different version of Activity (JAXB is somewhat
flexible in terms of consuming documents with additional XML it does
not understand). Or use some XPath on DOM.
WADL can be used to help create the human readable documentation that
can be served as part of the service. Jersey dynamically creates a
WADL description of the service, see also here:
http://wikis.sun.com/display/Jersey/WADL
If you really want static client stubs you could use the wadl2java
facility available from:
