Hi,
I am now initializing GMS as follows:
Properties props = new Properties();
props.put("LOOPBACK", "true");
props.put("MULTICASTADDRESS", "127.0.0.1");
props.put("MULTICASTPORT", "2299");
return (GroupManagementService)
GMSFactory.startGMSModule(serverName,
groupName, GroupManagementService.MemberType.CORE, props);
and I have opened up UDP and TCP port 2299 (should I open TCP or UDP?).
With this configuration, it still doesn't work and I have to shutdown
the firewall to get it working.
What am I doing wrong here?
Cheers
Erik
