Unique IP Address Is Needed to Create an Application Server Connection
In Oracle JDeveloper, when you create a connection to a 10.1.3 application server that has multiple IP addresses, the Test Connection function returns the following error message:
Error getting OC4J Process for: ... : Error connecting to OPMN (is it running?): Connection refused: connect

You must specify a unique IP address when creating a connection to the server from Oracle JDeveloper.

具体修改如下

In $ORACLE_HOME/opmn/conf/opmn.xml there is a <notification-server> element, by default it looks something like this:
   <notification-server>
      <port local="6100" remote="6200" request="6003"/>
      <ssl enabled="true" wallet-file="$ORACLE_HOME\opmn\conf\ssl.wlt\default"/>
   </notification-server>


I added a ip-addr tag as follows:
   <notification-server>
   <ipaddr remote="0.0.0.0" request="0.0.0.0"/>
      <port local="6100" remote="6200" request="6003"/>
      <ssl enabled="true" wallet-file="$ORACLE_HOME\opmn\conf\ssl.wlt\default"/>
   </notification-server>


That way the opmn server listens to all IP adresses instead of just to 127.0.0.1 (which apparently is the default). Note that there may be security issues with this as I haven't looked into that (my goal was just to get it working).

After changing the config you'll have to reload opmn.xml (or just reset opmn) and voila.
