I think, that could be useful implement support for security in visual editor
for ejb-jar.xml.
Especially visual editor for these elements:
  <assembly-descriptor>
    <security-role>
      <role-name>USERS</role-name>
    </security-role>
    <method-permission>
      <role-name>USERS</role-name>
      <method>
        <ejb-name>AccountStateBean</ejb-name>
        <method-name>*</method-name>
      </method>
    </method-permission>

The security should be editable also for methods .
