Jade DispatcherException problem when using remote Containers

Question

I have two virtual machines in a private cloud, and I want to execute Jade both of them. They can access each other without problems. I started in one of them the Main Container, and in the other a Container which would connect to the main. However, I get a Dispatcher exception when this connection tries to take place:

In the other node I get the following:

Any ideas about what I am doing wrong?

Thank you very much in advance,

I managed to solve the problem. It did not work because in the local-host parameter the value was localhost. I changed it to the External IP Address and it worked — Javier J. Salmeron Garcia, Jun 22 '11 at 15:12
Hi Javier, you might think about writing up the solution you found if you think it might be helpful to others, or consider closing or removing the question. — Peter Coulton, Jun 24 '11 at 00:20

To me, this worked

String[] container = {
        "-gui",
        "-local-host 127.0.0.1",
        "-container",
        "Agent1:jogo.agents.Agent1;Agent2:jogo.agents.Agent2"   // <- Your custom agents
    };  
Boot.main(container);

The problem was that in the node I put:

local-host:127.0.0.1

This was solved by putting

local-host: <actual IP of the machine\>
