[jdom-interest] JDOM Xerces and Xalan versions

[Joel P. Worrall]

Greetings:

I am experiencing ClassCastException when attempting to use the JDOM
SAXBuilder with Tomcat 4.0.1 on the JDK 1.4.  It's trying to cast a
SAXParser to an XMLReader (which I have built the source for and know it
implements... very strange)

A couple questions.  Is JDOM capable of working with both those products?

Also, what are the versions of xerces and xalan that ship with jdom7?  Can
they work with the latest of both thsoe projects?

Exception below:

org.jdom.JDOMException: Error in building:
