That was really bad advice - please forget I said it.
 
While it worked for me at home, it won't work here.
 
I'll continue to look into it, and let you know.
 
Cheers,
Brett

There is no jaxp.jar in $TOMCAT/lib but these files:
 
jasper-runtime.jar
naming-factory.jar
 
In $TOMCAT/commons/lib are the crimson files:
 
crimson.jar and jaxp.jar , but don't know if you are talking about these
files.
 
Thanks.

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

This app was running well in tomcat 3.3 b2 

jakarta-struts and jakarta-commons jar files are from September 19th. 

XML SAX parser is Xerces 1.4.1 whose jar file is in 
$TOMCAT/webapps/myapp/lib 

O.S. Windows Millenium 

Java version is 1.4 beta2 

Any suggestions ?
