I had this problem the other day and martin cooper helped me out with it.
Tomcat 3.2.3 has an earlier version of jaxp in it's lib directory. I
replaced Tomcat's jaxp with a newer one and got past that problem. This
was with Struts 1.1 nightly build - with Struts 1.0 and Tomcat 3.2.3 I have
had no problems at all. Unfortunately, after I got past the Namespace
problem I ran into a problem with class not found on ActionFormBean that
several others have also had (see thread : Digester throwing
ClassNotFoundException for ActionFormBean). I then tried Struts 1.1 with
Tomcat 4.0 beta 7, and ran into yet another problem related to the action
servlet initialization (mappings and/or formBeans collections null) that
has been much posted of late.
I read the tea leaves and gave up on Struts 1.1 for the time being - I
didn't have time to fool around with classpath / classloading issues. I
went back to Struts 1.0. I'm keeping an eye out here to see if there are
ever any definitive explanations / solutions for the Struts 1.1 / Tomcat
3.2.3 errors though, so if you get it working - please post!

Hi,
I am trying to run latest version of struts on Tomcat 3.2.3 (standalone)
mode and getting the following error when I try to startup the Tomcat.
I downloaded latest version of Xerces parser and Jaxp-1.1 but it doesn't
work with anyone of these. (I copied the parser jar files in my
tomcat/webapps/struts-example/web-inf/lib directory). I am running this on
Windows 2000. Please let me know where I am making a mistake.
