#1 Problem starting HelloWorld portlet

[Onno Scheffers]

I read in the feature requests about the Digester not
being able to validate the portlet.xml when you're
after a corporate firewall.

I think I had the same problem, I got 403 errors when
trying to start JBoss, but after I put the dtd locally
I got another exception from the digester:

15:17:54,733 ERROR [Digester] Begin event threw exception
java.lang.ClassNotFoundException: No ClassLoaders found
