# Via xml

The above @EJB annotation usage is 100% equivalent to the following xml.

    <ejb-ref>
        <ejb-ref-name>myFooEjb</ejb-ref-name>
        <remote>org.superbiz.refs.FooRemote</remote>
    </ejb-ref>
    <ejb-ref>

    <ejb-ref-name>org.superbiz.refs.MyEjbRemoteRefBean/myBarEjb</ejb-ref-name>
        <remote>org.superbiz.refs.BarRemote</remote>
        <injection-target>
          <injection-target-class>org.superbiz.refs.MyEjbRemoteRefBean</injection-target-class>
          <injection-target-name>myBarEjb</injection-target-name>
        </injection-target>
    </ejb-ref>
