Re: [jboss-dev] Howto debug jndi lookup issues?
Adding this to every test would be real ugly, but as a quick debug
you can catch this and invoke Reference.getFactoryClassName(). It's the
absence of that factory class that causes
javax.naming.spi.NamingManager.getObjectInstance() to return the passed
in Reference instance of creating the desired object.
I opened a JIRA to have the JBoss NamingContext class detect this
situation and add some useful debug output:

Still, is there a way to know what class is missing exactly?
