Re: Random ArrayIndexOutOfBoundsException

[Gabriel Egolf]

Sadly, I don't think it's gonna be a fix for this problem.  I ran the 
Environment Check stylesheet and it looks like my servlet engine is 
using the correct Xalan version - 2.3.1.  I'll attach the relevant XML 
output at the end.

There was an observation that I might have some threadsafe coding 
problems.  Most of the errors appear in pages where simple 
transformations (XML + XSL -> XHTML) are happening.  I really am rather 
at a loss.  Any other ideas?

Really?  I don't recognize that error as the typical endorsed lib
problem, and thought Jetty handled endorsed libs differently and
so didn't suffer this problem.  Gabriel, did this work?

Hello Gabriel,

you seem to have the infamous endorsed libs problem. Try the environment
check mentioned at
http://wiki.cocoondev.org/Wiki.jsp?page=NoMoreDtmIdError to be sure.
Also a short overview about solutions is given. A more complete
description of the problem can be found at
http://wiki.cocoondev.org/Wiki.jsp?page=EndorsedLibsProblem.

Hello all.

I'm in the last stages of development on a rather large
     

project, and for
   

some time now have been plagued by a rather annoying problem.  I'm not
sure even how the problem began, but I'll try to give as much
information as possible and hopefully one of you has run across it in
the past.  Generally, the problem manifests itself as a blank page
containing nothing but the XML PI (<?xml version="1.0"
encoding="utf-8"?>).  Occasionally, I'll get the contents of 2
     

unrelated
   

pages together.  Unfortunately, this problem seems to be a completely
random occurence, and usually a server restart will solve it
     

temporarily.
   

Here's my software environment:
JDK 1.4.1_02
Jetty 4.2.9
Cocoon 2.0.4
I've supplied an error trace from my error.log at the end of this
message.  If you've seen this before, please let me know how
     

you fixed it.
   

Thanks.
