Below code will add role to user, Revoke role from user, Fetch Role from user
======================================================================
For Client Code below JAR need to be added in Eclipse or JDeveloper.

1) commons-logging.jar
2) jrf-api.jar
3) oimclient.jar
4) spring.jar
5) wlfullclient.jar
