Ion Olaru on "Changing the Jetty port"

Hi

I am trying to deploy 2 instances of Cassandra 1.2.5 + their respective agents + 1 opscenter on the same box, my local development box, I know this is weird, but I would like to have this configured locally before I move forward.

WARN [Jetty] 2013-05-24 23:02:46,794 FAILED org.eclipse.jetty.server.Server@4c18e99: java.net.BindException: Address already in use

My error now is the Jetty server Exception coming form the 2nd agent on start:
I was wondering if I have any control on what port jetty should run.

Thanks
