Background :
============

I'm porting Batik to Jesktop.  It's 99% finshed and quite a whopper of an 
application.

Problem :
=========

Included in Batik is org.xml.sax classes.  The factory tries to dynamically 
load a parser.  Batik
wants crimson (crimson-parser.jar).  Avalon already has org.xml.sax in 
classpath, so classloader
uses the factory from the one with Avalon, not the classes loaded by a 
different (leaf)
classloader for Batik in Jesktop in Avalon.  Of course that's right (security), 
but wrong becase
the top level, Avalon, classloader knows nothing of the leaf classloader and 
it's clearly visible
crimson jar.  

Solution #1
===========

Talk to the poeple at www.xml.org and get them to add a classloader param to the
XMLReaderFactory.createXMLReader() method.  Same trick as used for Repository 
(talked of recently)

Solution #2
===========

Delete org.xml from my fork of Batik, place crimson-parser in pheonix's libs 
directory.

Summary
=======

Naturely I opted for solution #2, but it feels hacky.  I'll email David 
Megginson (Mr SAX).

Incidentally, the classes are marked as...

  // NO WARRANTY!  This class is in the Public Domain.

... which surely means that all GPL cannot import it ;-)

Regards,
