Hi I can't help I'm afraid but am having a similar problem. 3.2.2 says that it has deployed the jar and added to the classpath. However I then get a class not found error on one of the classes.
Can anybody suggest what might be causing problem, I know Jboss had a lot of different class loaders is that issue?
JBoss 3.2.2 seems to be slightly sensitive to WAR classloading. This may have to do with work performed to address other classloading issues. The only clear-cut solution I have found is to place the JAR in JBOSS_HOME/server/default/lib or whatever is appropriate for your run-time instance of JBoss (all, default, minimal).
You might also consider jboss-web.xml with a <class-loading java2ClassLoadingCompliance='false'/> element to force classloading to operate up the hierarchy instead of down it. i.e. Start within the WAR scope and then move upward. YMMV.
