Re: File upload servlet won't run on AS/400 butrunsOKonPCconfiguredidentically - resolved

YES!!!!!!!!!! I had a copy of cos.jar in /QIBM/UserData/Java400/ext. I deleted it and it works now.

A big thank-you to everyone who responded, especially Johnny!

The exact same version you have - 4.1.12.

I also initially tried shared/lib, but it didn't work. I also needed to
end and restart Tomcat to get it to work.

One other thought - do you have cos.jar anywhere else, like in
/QIBM/UserData/Java400/ext or any of the other system class path
directories? That may interfere as well. I think it has something to do
with the cos.jar classes being available to the system class loader versus
the Tomcat custom class loader... If they're available to the system class
loader (that loads Tomcat when starting), you have problems when Tomcat
tries to load them with it's own custom class loader... I'm a bit fuzzy on
exactly how that all works, but maybe someone on the list has a better
understanding of it?

Good luck!
Johnny

I've tried putting cos.jar in common/lib with no luck and I've tried
/shared/lib and no luck.

You've got yours working now? If so what version of Tomcat?

Thanx, PLA

I had the exact same experience... I never discovered (or understood?)

why

it was happening, but I was able to fix it by putting the cos.jar
(com.oreilly.servlets classes) in the /jakarta-tomcat-4.1.12/common/lib
directory. My gut feel is it has something to do with the tomcat class
loader, but I don't know enough about that to really know what was
happenning.

Good luck!

Hi

I've got a file upload servlet that works fine running on a PC with
Tomcat
4.1.12 but I get the error below on the AS/400 running Tomcat 4.1.12.
I've
written hundreds of servlets on the AS/400 and the PC and I've never

had

one beat me like this one. The error says "NoClassDefFoundError:
javax/servlet/http/HttpServletRequest" but that is not logical since I
have dozens of servlets running OK. Any one have any suggestions?

Thanx, PLA
