Hi Ahmed,
does your Member class contain associations to other classes? If yes,
I guess to have to repackage the lists as well... (i.e. create a new
Hashtable and so on). Another question could be if you can have
annotated classes on the client or you have to copy those classes as
well, i.e. have a plain pojo and an annotated pojo... - you could just
try with a few samples...
Hope this helps
Sebastian
