Getting ClassNotFoundException for JasperLoader12 and AdaptiveClassLoader12

First, here is my system:

SuSE: 7.2
Apache: Apache/1.3.19 (Unix)  (SuSE/Linux)
Java: JDK1.3
Jakarta: Jakarta-3.2.1

I'm running a JSP engine/Apache web server
environment. Everything seems to be working fine
except I get the following exception while it's
loading the initial applets. Despite getting this
exception, tomcat does not die and proceeds to operate
OK.

Just wondering if anyone knew what this meant. The
exception is:

>>>>>>>>>>>>

Re: Getting ClassNotFoundException for JasperLoader12 and AdaptiveClassLoader12

Posted by Chris Yunker <ch...@yahoo.com>.

Well, I just downloaded Tomcat 3.2.3 and that solved
the problem. This version includes the class files
which were missing (and causing the exception below)
in version 3.2.1.
