lidgaca, I had the same issue and resolved it by specifying the rmi server host name in "bin/run.sh". open that file and add the following line: -Djava.rmi.server.hostname=localhost In the alpha release the problem was fixed by injecting the hostname into the naming service from the configuration object. I talked to Celbert about the problem, I guess they didnt have time to fix it yet but you can use this as a workaround. I have to say that JBM2 team did an amazing job, I was playing with it for a while now and I am getting great results, I cant wait to try the cluster - I tried the Beta release from the trunk and was not able to make the cluster work - I guess I have to wait.
