[murthy_j2ee]

  Hi All,
	Can any body please tell me how to call ejb from a java bean. I have done it it as below.
  
  Here is the client calling an EJB.............. 
               {   
  
  		Context ctx = new InitialContext();
		Object obj = ctx.lookup("UserAuthentication_Session");
		UserAuthentication_SessionHome                home=(UserAuthentication_SessionHome)javax.rmi.PortableRemoteObject.narrow(obj,UserAuthentication_SessionHome.class);
		UserAuthentication_Session rem = home.create();
		loginValue=rem.validateLoginDetails(username,password);
	       }

  Here is ejb-jar.xml..............................

      
         UserAuthentication_Session
         <ejb-name>UserAuthentication_Session</ejb-name>
         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>
         <transaction-type>Container</transaction-type>
      
  Here is jboss.xml to specify the jndi name for my EJB.......................................
      
      
         <ejb-name>UserAuthentication_Session</ejb-name>
         <jndi-name>UserAuthentication_Session</jndi-name>
      
 
  Here is the error trace....................................
               
          Throwable while attempt to get a new connection..
 
  please tell me what was the problem, and also please tell me how to configure it in jboss.
