Re: File upload servlet won't run on AS/400 but runs OKonPCconfigured identically

Patrick:

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!
Johnny

   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
