1.) Is that the full stacktrace that is displayed?
2.) When is the exception thrown? What will the other users be trying to do when the exception is thrown?
3.) What's special about the users who are getting the exception?

I just removed your other identical thread. Please don't do that: it confuses other
forum members and they might do work that has been done already in your
other thread.

kind regards,

You've decided to answer only one of the questions I asked above?
From that trace you can see of course that it's the famous nullpointer which is hitting you from the BCHelpform JSP. A few printlns in there and you be knowing exactly which object is null too.
