[jdom-interest] IllegalAccessError

[Jason Hunter]

If you look at XMLOutputter you'll see a little trick regarding how
NamespaceStack is made accessible.  Seems like Tomcat's funky class
loader strategy may cause this problems.  You're going to need a
classloader superguru to identify the cause.

Meanwhile, be careful: if you output <BR> instead of <BR/> you're no
longer writing XML.
