RE: Coocoon NullPointerException Version 1.5
First question that comes to my mind: Would it be possible for you to test on a plain tomcat instance and see if you get the same nullpointer? If it works fine there you already have some idea on where to continue the investigation.

RE: Coocoon NullPointerException Version 1.5
The fact that you are not able to reproduce this on your test environment does in some way already give some hint. Although I must admit some problems (concurrency, memory, ...) only reveal themselves on production environments. A few other questions: - are you using the same setup on test and prod (application container + version, OS, ...) - are there any dependencies which could cause a nullpointer (missing property, perhaps missing value in database) - is the exact same war file deployed AS IS from TEST to PROD? - is the app interfacing with other systems that could behave differently? ... From the stacktrace I can't really make out a lot so I think it makes sense to analyze what that xsp is doing and check at what line in the xsp the exception is thrown to get more clues.

RE: Coocoon NullPointerException Version 1.5
One other remark: Although it's been at least 6 years ago I've written xsp's, I do however remember that it was possible to overwrite the xsp's in the exploded war folder. Maybe you need to set some flag somewhere in order for Cocoon to recompile them on-the-fly..not sure though. I would add some extra logging statements to that xsp just for debugging purposes to find out what line is causing the nullpointer and start investigating from there. And you can safely replace the original xsp back after you're done.
