Subject Re: persistence problems in consumer having java exception
Date Thu, 23 Oct 2008 13:54:28 GMT

Thank you for the replied Hans,

i used version 5.1.
it's during MessageConsumer.receive()
just simply have NullPointerException. at first, i got XFireRuntimeException
when i try to visit web service at consumer code by use xfire.
these only one way i can get a persist message at db is i mark a debugging
at consumer code to stop the consumer thread, and i keep running the
producer thread, then i got the persist message. even though, it still won't
persist the first message. which mean after i stop consume 3 message, these
are only 2 message will persist at db.

thank you for the help...

David
