Hi Rogerio
You have to designate one of your Shoal processes as a virtual multicast
router for this purpose by passing in a Properties object using the
following keys:
Properties p = new Properties();
p.put(ServiceProviderConfigurationKeys.IS_BOOTSTRAPPING_NODE.toString(), "true");
p.put(ServiceProviderConfigurationKeys.VIRTUAL_MULTICAST_URI_LIST.toString(),
"comma separated tcp://ipaddress:port uri list");
The above tcp://ipaddress:port url should be passed to all processes at startup.
The port can be any unbound available port.
At the moment, only the first uri in the list is used inside shoal. We are yet to
add support for handling multiple uris acting as software routers.
Could you take a look at the cross subnet demo code from the shoal
sources located under shoal/gms cvs and follow the convention for using
the appropriate ServiceProviderConfigurationKeys ?

Let us know how it goes.

I'm trying to solve the communication problem. After it I'm going to test the application again in different machines, If the problem persists I'll send you the logs.

I'll have only CORE members (n), but only the leader will have the power to do things such as connecting to other systems, etc. When I test the application running many instances (members) in the same machine, the application works well, but when I test each instance running in different machines at the same network, the application doesn't work well, sometimes it elects more than one leader, which couldn't happen in my application logic. Do you have any idea of what is happening?
