java.lang.reflect.InvocationTargetException on WebLogic 8.1 SP5 & Oracle 9i

[Migrated From Jforum.net]

Hi, I successfully installed JForum v2.16 using the manual method (not using data source) on WebLogic 8.1 SP5 with Oracle 9i. But when I tried to register, I was presented with the following error messages:

An error has occurred.

For detailed error information, please see the HTML source code, and contact the forum Administrator.

java.lang.reflect.InvocationTargetException

And following is the error stack trace:

In addition to the above error, I realised I (as administrator) can only see a category in the category listing only if I created it under the group "Administration", not so if under "General". Is this a problem or the standard behaviour of JForum?

This exceptions may be related to some security policies of the machine. I have seen this problems in red hat fedora as well, because some missing libs.

About the Category question: try resaving the permissions: Admin Panel -> Groups -> Permissions

Sorry that I had forgotten to mention the machine is installed with SunOS 5.8 (Solaris 8 equivalent). Can this problem be potentially related to missing X11 libraries as I have read in other posts? If it related to security policies, which area should I start investigating?

Thanks for the prompt reply.
