--------------------------------------------------------------
the root problem described in the 1st post is solved, it was the import of the client-jars from JBoss.
but i dont have a clue about the 2nd problem.
imho the situation is the following (i assume):
Client knows his Classes (also Entities, because would have crashed earlier).
Server knows his classes too (same as above).

at the call with the company as argument client tries to marshal company c with classes of JBoss but did not get access via RMI (i dont know WHY the JBoss tries to return a class to the client, because the client have these class and my entity implements Serializable).

Full Stacktrace:
