endorsed classes

I read a post stating the endorsed directories have a higher class loading 
priority than any of the Tomcat class loaders in Tomcat 4.1.

I found this in the link from 
http://tomcatfaq.sourceforge.net/classnotfound.html entitled "Another 
answer to a classloader issues."

Does this mean you can never override the Xerces version (xercesImpl.jar) 
or parser APIs (xmlParserAPIs.jar) since these are in 
$CATALINA_HOME/common/endorsed?

If so, this is the source of my problem trying to use Xerces 1.4.4 and JAXP 
1.1.
I get a VerifyError each time I try to use the 
setErrorHandler(org.xml.sax.ErrorHandler) method in my application.
This worked fine with Tomcat 3.2.4 in-process but fails every time in 
Tomcat 4.1.24 out-of-process.

Please help.  I have been stumped by this VerifyError for over a week now.

Thanks.

You have code compiled against Xerces 1.4.4 and wish to run in tomcat4 which 
has xerces 2.3?

I don't have an answer but am curious in this thread.
