Alan still my question is not answered or i haven't got ur point

    I got why  role mapping have to be  inside openejb-jar.xml .

    but why it has to  inside every EJB in openejb-jar.xml.
     
    if i have 10 beans do i have to declare my role mapping in each
and every bean.
    
    Aren't role mappings independent of ejb security. I mean we define
the ejb security in method-permissions using role names.And role
mappings is just to bind principals with a role names.
