Hello MQ Gurus,

I looked around the forum for information on the below but was of no help. I am getting the following error when I get a message from MQ server to my WL bridge. The exception just says java.lang.NullPointerException without any more stack trace information as to which information is missing.


2009.02.17 11:30:17 MQJMS1016E an internal error has occurred. Please contact your system administrator. Detail: java.lang.NullPointerException

tor. Detail: java.lang.NullPointerException



Is there any flags in weblogic startup script I can use to debug this more?
Currently I have the following setup

set SYSPROP=%SYSPROP% -Dweblogic.Debug.DebugMessagingBridgeStartup=true
set SYSPROP=%SYSPROP% -Dweblogic.Debug.DebugMessagingBridgeRuntime=true
set SYSPROP=%SYSPROP% -Dweblogic.Debug.DebugMessagingBridgeRuntimeVerbose=true
set SYSPROP=%SYSPROP% -Dweblogic.debug.DebugJMSBackEnd=true
set SYSPROP=%SYSPROP% -Dweblogic.log.StdoutSeverity="Debug"

OR

is there anything I shoudl be aware of?

Please help if possible.

-Cheers
BDB

You could try trapping the linked exception, which often contains more information including the MQ Reason code.

It is not even reaching the MDB. I tried to let my MDB catch the LinkedException. My bridge starts transferring and it shows in my console.
Any ideas?

Ok... I just saw this in my trace...
