Class Not Found Error for WebApp

Hi,

I am using Tomcat4.1, Apache2.0.4, Linux Redhat9.0,
j2sdk1.4.2, and WebApp connector I downloaded from
CVS.

I created webapp.so module and .jar file and place it
in server/lib and I am gettint error class not found
when trying to start Tomcat4. I tried puting classes
directory from warp/build/ to /var/tomcat4/common and
it didn't help. Here is the error trace from log file
(catalina.out):

Re: Class Not Found Error for WebApp

Caused by: java.lang.NoClassDefFoundError:

NoClassDefFoundError != ClassNotFound

The two are different.  NoClassDef means that the class that is being 
found is not the one that is expected, not that the class is not found. 
   This comes up weekly at least, if not more often, try searching the 
archives.
