JDev 10.1.3 embedded OC4J: How to run HTTP in port 80 without conflicts?

Question

Hi
I need to run the HTTP protocol using port 80 in the OC4J embedded version that JDeveloper 10.1.3 brings. I don't want the port to be decided at run time. I'm trying to configure it to use port 80, but I get conflicts and the port reconfigures to another value (1024). I need the port to be 80 in order to be consistent to the production port. (Why? Because I'm using SSLEXT, for those who are familiar with it).
How can I understand the conflictand resolve it? How can I know the conflicting process that demands the port 80?

Only way you can change this is to hack jdeveloper...
in jdev.jar (or jdev-sr.jar if you have service pack) find Oc4jPortConflictUtil.class and replace it with compiled code below.
package oracle.jdevimpl.runner.oc4j;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.ServerSocket;

            ArrayList portConflicts = new ArrayList();
            _admin.setHttpPort(reservePort(0, _admin.getHttpPort(), 23, portConflicts));

            _admin.setJmsPort(reservePort(2, _admin.getJmsPort(), 25, portConflicts));

                _admin.setIiopPort(reservePort(3, iiopPort, 26, portConflicts));
