Security Problems

[Caroline Wood <Ca...@cpp.co.uk>]

I've written a JMS appender which has passed test and seemed to work fine.
Yesterday, however, when integrating the appender with a different
application, it fell over with the following error:

log4j:ERROR Could not publish message in JMSAppender [mAppender].

Now, the user cpp and the group PPSGroup are set up on my weblogic server.
Why is there a problem here?

Thanks.
