    Can't help much on this, except point you to Oracle Application Server Container for J2EE Security Guide:

  3. well[ Go to top ]

    i dont know much about oracle but usually

    the java:/ name space is for components on the server

    the / "empty" name space is for everyone

    and the java:comp name space represents the component name space

    remote ejbs sould use the "/" empty namespace in order to be accessed from remote

    Hi Srini,

    Which user are you looking up the EJB as and have you setup any permissions for the ejbs as follows in the ejb-jar.xml?

     <security-role>
         <role-name>BeanUsers</role-name>
        </security-role>
        <method-permission>
          <role-name>BeanUsers</role-name>
          <method>
            <ejb-name>SystemTimeSLSB</ejb-name>
            <method-name>*</method-name>
          </method>
        </method-permission>
      </assembly-descriptor>


    Make sure that your user is in the group that is mapped to the role. The role to groups mapping are done in orion-ejb-jar.xml as follows:

    <assembly-descriptor>
        <security-role-mapping name="BeanUsers">
          <group name="systimeBeanUsers" />
        </security-role-mapping>
      </assembly-descriptor>


    And the security provider either JAZN-XML or LDAP is defined in the orion-application.xml.

    Can you try accessing the ejb as admin user and see whether you can invoke the EJB ?

    For details you can see this how to http://www.oracle.com/technology/tech/java/oc4j/htdocs/how-to-security-JAAS.html
