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
