This is a classloader incompatibility between JBoss and Apache. I don't have
the code in front of me, but looking at the stack trace, there should be a
point where the digester is set up, but before it is really used to do
anything, most likely in com.fgm.web.menu.MenuRepository.load(). So you need
to add the last line:
...
Digester digester = new Digester();
digester.push(this);
->> digester.setClassLoader( getClass().getClassLoader() ); <<-
...
It might already even be in there, waiting for you to uncomment it.
I have no clue why this problem keeps coming up with Digester, but it's
pretty tiresome.
