[jboss-user] [Beginners Corner] - Help understanding 'No ClassLoaders found for ...'

[giannidoe]

I'm trying to load up some configuration data in a web app from an xml file using Commons Digester and I get the following exception.
I'm a bit perplexed as the class is present in my war and it works fine under another application server.
