For the record... My Problem actually had nothing to do with what the exception said... (as usual :-))
My Route now looks like this: from(routeStart). transacted().routeId("pserun.fullrun.route").inOut(). to("zlog:com.innoq.zifs?level=info"). setHeader("chunksize", constant(sizeofchunk)). bean(bean, "createNewPSERun"). bean(bean, "getActivePSERun"). bean(bean, "createNewChunks"). split(body()). to(ExchangePattern.InOnly, wlDistributor). setBody().simple(STARTED); The important change is that i told the jms-producer to have a MEP INONLY, whereas the whole route is MEP INOUT. I tried that out because of a "gut feeling" and it turned out to be the solution.... pfff... Although i still don't understand why it did get to that exception... -- View this message in context: http://old.nabble.com/Method-setExceptionListener-not-permitted-in-J2EE-Servers-tp28693246p28739896.html Sent from the Camel - Users mailing list archive at Nabble.com.
