Re: File upload servlet won't run on IBM AS/400 but runs OK on PCconfigured identically - resolved

[Patrick L Archibald]

I had a duplicate copy of cos.jar in the /QIBM/UserData/Java400/ext directory. I deleted it and it works now.

A big thank-you to everyone who responded!

I have servlet.jar in other directories but there is only one within the "/jakarta-tomcat-4.1.12" directory. I've tried putting cos.jar in common/lib and shared/lib. No difference.

Thanx, PLA

I have gotten weird errors when more than one classloader loads a class.

With that in mind, is the servlet.jar in more than one place? Check in
$CLASSPATH, $CATALINA_HOME/common/lib, $CATALINA_HOME/server/lib,
$CATALINA_HOME/shared/lib, your applications WEB-INF/lib, and the
$JRE/lib/ext directory.

You might also check the location of the jar containing the
com/oreilly/servlet/MultipartRequest class. I would try to put it in
common/lib (the only place that servlet.jar should be) to make sure they
are loaded by the same classloader.

Hi

I'm stumped on this problem. 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

IBM 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
