Starting the Derby Network Server on a new port

I was testing WSO2 ESB on IBM Websphere and I could not get the Derby server inside Websphere running and therefore wanted to start a new Derby server outside Websphere. I was struggling to get this working till I came across a link which was specified by one of my colleges in one of the WSO2 ESB forum posts. In that article it clearly specifies how you can start a new Derby server on a new port.

NetworkServerControl start -p 1528

Generally when you start up WSO2 ESB it would start a Derby database which is embedded inside WSO2 ESB. Therefore if you want the ESB instance to listen to the new Derby server which you started on port 1528 then all you have to do is set the following property to false of the ESB_HOME/webapp/WEB-INF/classes/conf/server.xml file.

<StartEmbeddedDerby>false</StartEmbeddedDerby>
