I am having a problem that I do not know how to fix or even find the cause. I have some code that takes an existing pdf file, fills out the fields and saves it as a new pdf file. I'm using the big faceless organization libraries for editing the pdf. When I run this code in a JSP page on Wesphere 3.5 it works fine. When I run the same code in Websphere 4.0 I get a null pointer exception. Does anyone have any idea how to find the cause of this problem? Could it be that the jdk was changed from 3.5 to 4.0 and IBM left something out? As a side note, I can create a new pdf in 3.5 and 4.0, the problem only occurs when I try to edit a pre-existing pdf.
Any help would be greatly appreciated. Thanks in advance.

WAS 3.5 is using JSP).91 & 1.0 where as WAS 4.X uses JSP 1.1,t his might cause some problem.

You will have to provide more information about the problem. Can you put in the stack trace so that we can have a look as to which class is giving the NullpointerException
