You are getting a NameNotFoundExcpetion, which means that the name you are looking up in JNDI is not correct. See http://wiki.jboss.org/wiki/DebugBindException for steps on debugging this error. Also, I assume that com.b2b.emonitor.util.dispatch.ControllerHome FactorySingleton is one of your classes. You really should compile your classes using the debug compiler option. With that option the line numbers will show up in the stack trace, letting you know which line in that classes source file you are doing the lookup.
