I feel a bit sheepish about it.But the Failure was much simpler then
you all could imagine (obviously):
simply i missed "extends RemoteService" !
but now it seems i got a real problem: the 3rd party class the server
side uses jpa2 as mentioned before. and its code now throws "no
persistence unit found". But the unit exists: in fact this 3rd party
jar is executable and its running fine stand alone (the
persistence.xml is contained in jar file, packed by maven-assembly-
plugin).
so it seems that the access to "persistence.xml" is some how
restricted if the jar is accessed thru jetty/myApp?
