No Class Def Found Error when deploying the OIM web service

I got this error when i deployed OIM SPML webservice. And i was able to resolve this by appending the JBOSS_CLASSPATH with E:\jboss-4.0.2\client\commons-discovery.jar;E:\oim\jboss-4.2.3.GA-jdk6\client\commons-logging.jar; in the jboss run.bat.
