Subject RE: Tomcat 4.0 and Struts.

I had the same problem. I removed jaxp.jar from the tomcat lib directory, as
it seemed to be conflicting with Xerces. Removing Xerces from the classpath
also works, but I use another library that depends on it.

Cheers,
Brett

I made a mistake when writing about the location of the xml parser...

It is Xerces 1.4.1 and is placed in $TOMCAT/webapps/myapp/WEB-INF/lib

Is there any issue regarding the use of Tomcat 4.0 and struts when dealing
with the "digester parsing" of the struts-config.xml ?

This is what´s been written to log file in tomcat 4.0
