WebLogic network-access-point

If you need to invoke operations (EJB, WS...) on a specific IP different from the main listen address / port of WLS, you can create inside config.xml a network-access-point and give it a mnemonic name like "INT-Channel" :

   <network-access-point>
      <name>INT-Channel</name>
      <protocol>t3s</protocol>
      <listen-address>1.2.3.4</listen-address>
      <enabled>true</enabled>
      <two-way-ssl-enabled>true</two-way-ssl-enabled>
      <client-certificate-enforced>true</client-certificate-enforced>
    </network-access-point> 

and configure your component in your weblogic-ejb-jar.xml with a clause:

<weblogic-enterprise-bean>
     <network-access-point>INT-Channel</network-access-point>
</weblogic-enterprise-bean>
