When I posted a link on how to use the JBoss forums, I meant for you to post
more information, not post in the beginners forum.
Your post contains no useful information, it mentions neither a jboss error message
or a jboss stacktrace.
i.e. what is HL7ToQueueMsgAdaperService? - it is certainly not a part of jboss.
I suspect HL7ToQueueMsgAdapter is part of a third-party product to handle Health Level 7 XML messages.
If this is the case, you should probably take this up with the vendor/project that provided your HL7 messaging capability.
If HL7ToQueueMsgAdapterService is something you developed in-house, you should definitely go through the code and make sure the run() method passes a non-null Exception to every invocation of error().
