What can I say? Your code has a NullPointerException somewhere. It's in a method named saveGLData. It's at line 167, too, but that isn't going to help you unless you can find the
Java code that Websphere converted your JSP to. That's pretty much it. Good luck. Hopefully the method isn't too long.
This is one reason why you shouldn't put that sort of logic into a JSP. If you can't find the problem, I would suggest refactoring the JSP. Extract all that SAP update logic into a
servlet, where you have a much better chance of locating the problem. Have it forward or redirect to a JSP whose job is limited to displaying HTML to the client.
