Arullis,
I presume the packages whose names start with "com.atroad" (that appear in the stack trace you provided) are your classes (as opposed to WebLogic's classes). If that is correct, then I suggest you compile your classes with the "-g" flag. Then, in the stack trace, instead of "Unknown source", you will see the name and line-number of the offending source code. This may make it easier for you to debug your code.

Secondly, since you didn't post the part of your code that is causing the error, I can only suggest the obvious: are you closing your "ResultSet"s, "Statement"s and [database] "Connection"s?

Good Luck,
Avi.
