u can do this declarativlly like this:

1- in ur ejb.jar.xml:

  <assembly-descriptor>
......
    <security-role>
      <role-name>myMgr</role-name>
    </security-role>
    <method-permission>
      <role-name>myMgr</role-name>
      <method>
        <ejb-name>UrEjbName</ejb-name>
        <method-intf>Local {or Remote or Both}</method-intf>
        <method-name>generateBilling</method-name>
      </method>
.....
    </method-permission>

2- in ru orion-ejb-jar.xml do this:

    <assembly-descriptor>
        <security-role-mapping name="myMgr">
            <group name="myMgr" />
        </security-role-mapping>
        <default-method-access>
            <security-role-mapping name="&lt;default-ejb-caller-role&gt;" impliesAll="true" />
        </default-method-access>
    </assembly-descriptor>

3- in ur oc4j j2ee\home\config\principals.xml add a user and a group:

        <group name="myMgr">
            <description>myMgr</description>
        </group>

        <user username="MyMgrUser" password="password">
            <description>no description</description>
            <group-membership group="myMgr" />
        </user>

then u r sure that only member of MyMgr group can access the EJB API

u can also check that programatically if u called:

EJBContext.isCallerInRole("myMgr");
