Re: Selecting the correct version of XercesJ

Hi Desmond,

You're essentially asking how to keep a set of classes (could be Xerces; 
could be anything) local to your application running in Tomcat. If there's 
a built-in mechanism for doing that you should ask about it on the Tomcat 
mailing list(s), otherwise you would probably need to write your own 
ClassLoader if you don't want to use the Endorsed Standards Override 
Mechanism [1].

Thanks.
