[users@httpd] Error: 500

Hello,

I am using Apache 1.3.14 and Tomcat as a Servlet  Server
and I am getting the following error:

Error: 500
Location: /servlet/What
Internal Servlet Error:
java.lang.NoClassDefFoundError: org/apache/xerces/dom/NamedNodeMapImpl
           at java.lang.Class.forName0(Native Method)

I am a newbie with this web server stuff,  so any direction as to how to
troubleshoot this problem is very
much appreciated.

The error_log file does not have any entries,  but the access_log file has
the following:

10.100.138.65 - - [30/Aug/2002:10:48:48 -0700] "GET /servlet/What HTTP/1.1"
401 483

HTTP/1.1" 500 1254

Looks like your servlet is failing because it can't find a library it
requires (most likely the whole xerces is missing). Download xerces.jar and
put it in the lib directory of your webapp.

Anyway, this question will be better answered at the Tomcat user list
(tomcat-user@jakarta.apache.org)
