[jboss-user] [EJB/JBoss] - Problm while calling EJB

[murthy_j2ee]

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....

    ejb-jar.xml
   
   
    <ejb-jar >
 	   <enterprise-beans>
	      
        	 UserAuthentication_Session

        	 com.prospecta.WSOProject.User_Authentication.ejb.UserAuthentication_SessionHome
	         com.prospecta.WSOProject.User_Authentication.ejb.UserAuthentication_Session
	         <ejb-class>com.prospecta.WSOProject.User_Authentication.ejb.UserAuthentication_SessionBean</ejb-class>
        	 <session-type>Stateless</session-type>
