Simple thing like
response.setIntHeader("Expires", -1);
cause Exception in Jrun but not in resin. I am not saying Resin is better
than Jrun. Jrun is a great product as well. But I have no way to debug these
kind of exception because "response.setIntHeader("Expires", -1);" makes
perfect sense.

=>I can't help you if you don't pare down your JSP to a
=>reasonable size and post
=>it or send it to me or something. If the JRun errors are any
=>indication, you
=>have like 5 forwards in a single JSP, which could indicate a
=>pretty complex JSP
=>that you aren't able to debug or reduce. If that's so,
=>you'll blindly go from
=>one JSP engine to the next until one works. But given that
=>JRun and Resin are
=>two of the best, I don't think you'll get that lucky. So
=>you'll eventually have
=>to analyze the JSP and figure out what's wrong with it
=>anyway. Those "funny
=>exceptions" could be the key to your problem.
