Helloooo,
Can anyone help a newbie with how to interpret an exception stack? I have
had some luck debugging previous problems, when the exception occured in my
own code, as the stack info usually points to a line number or variable in
the source file causing the problem. However, for an exception like below,
how do I have any idea where the error is occuring, much less the possible
cause? I am assuming the "257" is pointing to the line of source in a
struts framework module, so it is not of use to me. Is that correct? If
it helps with the answer, I use the NetBeans IDE.
Thanks!
