Hi Everybody,
I am new to deploy EJB in JBOSS Application Server. I am succeeded to run configur JAAS in my JBOSS and abeled to run

it successfully. I have created my own Login Module and abled to authenticate it successfully by retreving the username and

password from database using. Now i want to call an ejb from login module instead of calling database directly. When i am

calling the Remote Ejb to get the instance of EjbBean i am getting the exception like Insufficient method permissions,

principal=null, ejbName=UserAuthentication_Session, method=create, interface=HOME, requiredRoles=[], principalRoles=[]

Here is the configurations in xml files....
