I have a webapp under Tomcat which includes in its WEB-INF/lib directory 
xerces.jar from Xerces-J v. 1.1.3. Whe I try to access my JSPs I get the error 
which is included bellow this description.Everything worked fine with Tomcat 
4.0.1 (I haven't seen it documented anywhere, but I think Tomcat 4.0.1 uses 
Xerces v 1.4.3 and Tomcat 4.0.2 and 4.0.3 includes Xerces v 1.4.4).

There's an obvious workaround which is removing xerces.jar from WEB-INF/lib 
(which makes everything work fine), but shouldn't it work anyway? I understand 
Jasper uses a different ClassLoader in order to have no interference from 
different XML parsers used by the webapps.
