Deployment Problem NullPointerException

[naumankhanca]

Hi,
I'm deploying a cmp bean in Jboss 3.2.1 and I made changes in standardjaws.xml and standardjbosscmp-jdbc.xml file but getting the NullPointerException. Does anyone has any idea,please let me know.
Regards,
Nauman

Please submit a bug report on the NPE with the package you're trying to deploy to sourceforge bug tracker (and the changes you made to standardxxx files).
