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>
