error with loading webapp when using certain libs

           Summary: error with loading webapp when using certain libs
           Product: Tomcat 4
           Version: 4.0.1 Final
          Platform: Other
        OS/Version: Linux
            Status: NEW

I have the following java jar files in my WEB-INF/lib directory:
jaxp_1.1.jar
jdom.jar 
xalan_2.1.jar  
xerces.jar

Every time my web application attempts to startup (when tomcat starts up) I get 
the following error messages:

2002-02-14 16:15:44 StandardContext[/mywebapp]: Servlet /mywebapp threw load()

It appears that maybe my xml classes are causing a problem with the classloader 
for catalina/tomcat?  Not sure why this would be since my classes are in the 
location that should provide isolation and not affect the internal workings?

Thanks,
Tony
