Basic MDB Question

[Renato J. Mascardo]

Using WLS 7.0 and JBuilder 7

I've created a MDB in JBuilder 7 and auto deployed it into an already
running instance of WLS 7.0. The MDB simply has a System.out in the
onMessage() method.

From within the WLS 7.0 Console i've configured the following settings ...
- JMS Connection Factory
- JMS Store
- JMS Server w/ JMS Topic

All the JNDI names are correct and the bean deploys normally.
I've also created a client which simply sends a message to the topic.

Problem:
WLS recieves the messages but they are never sent to the MDB and onMessage()
is never called. Is there a setting that I am missing. This example works
fine in WLS 6.1 but I can't seem to get it to work in 7.0.

After some time I get the following error:
<Jul 19, 2002 11:32:26 AM PDT> <Error> <Management> <140001> <Error getting

Don't know off hand. It seems tranage that you get the MDB error in the log
file, yet the stack trace is in a JSP. You might try posting to web
services or EJB.
