Try by deleting jbossweb.deployer/ directory.
Then probably other things that might depend on services inside this dir will fail,
try removing them as well, until things work w/o dependency errors.
Or you could try the other way around -- starting from minimal conf, and adding services on top.
You have to remove (from all configuration) jmx-console, manangement, admin-console, jbossweb.sar, jbossws.sar.
jbossweb.deployer (answer from Justin) sounds like JBoss4.x
But be aware you don't have a Browser interface to look after health and statistics of your JBoss!
