This graphic illustrates security mapping within the EJB Deployment Descriptor. The following sample code is shown:

    <enterprise-benas>
    ...
       <security-role-refs
          <role-name>POMgr</role-name>
          <role-link>myMgr</role-link>
       </security-role-refs>
    ...
    </enterprise-beans>
    <assembly-descriptor>
    ...
       <security-role>
          <role-name>myMgr</role-name>
       </security-role>
       <method-permission>
          <role-name>myMgr</role-name>
          <method>. . .</method>
       </method-permission>
    ...
    </assembly-descriptor>

This is an arrow from the `<role-link>myMgr</role-link>` line to the first `<role-name>myMgr</role-name>` line, and a second arrow from the first `<role-name>myMgr</role-name>` line to the second `<role-name>myMgr</role-name>` line.
