Hi Bryan, I've done this in the past by creating a custom ServiceSocketFactory [1] and using that when creating the TcpServerEnpoint:
ServerSocketFactory factory = new PortRangeServerSocketFactory(start, end); TcpServerEndpoint.getInstance(address.getHostAddress(), 0, null, factory); HTH Dennis 1. https://github.com/dreedyman/Rio/blob/master/rio-platform/src/main/java/org/rioproject/net/PortRangeServerSocketFactory.java On Nov 11, 2013, at 1208PM, Greg Trasuk <tras...@stratuscom.com> wrote: > > Hi Bryan: > > Yes, you can create multiple Exporters around one TcpServerEndpoint, so you > should be able to simply create an endpoint with the port you need, and then > use it multiple times.
