Jade Framework (two containers)

Question

I have expertise in using Jade in the same host (my laptop) as I can handle all interactions between agents; But I have to run the MainContainer in my laptop and the second container in a Raspberry Pi. I started to try a simple example by creating 2 agents, the first on the main container and the second on the container that will run on Raspberry Pi. But it doesn't work.

the following code is for the main container including agent1 which will send message to agent2

Runtime runtime = Runtime.instance();

Properties properties = new ExtendedProperties();
properties.setProperty(Profile.GUI, "true");
Profile profile = new ProfileImpl(properties);
AgentContainer agentContainer1=runtime.createMainContainer(profile);
Container.start();
AgentController agent1=agentContainer1.createNewAgent("Agent1","Connexion.Agent1",new Object[]{});    
agent1.start();

Code of the second container:

Runtime runtime=Runtime.instance();
Profile profile=new ProfileImpl();
profile.setParameter(profile.MAIN_HOST, "192.168.0.164"); //Raspberry Pi host
AgentContainer agentContainer1=runtime.createAgentContainer(profile);
AgentController agent2=agentContainer1.createNewAgent("Agent2","Connexion.Agent2",new Object[]{});
agent2.start();
agentContainer1.start();

• agent1 send message to agent2 every 15seconds.

There isn't any problem with the main container code but when I run the raspberry container using deployAndBrickPun ( ev3dev-lang-java ), it show me the following error:

I need to solve this errors, so I asking for your help please;

Thank you in advance.

Answer 1

you lack information within your profiles.

1. You need to defined IP,port, hostname on both (main-container and distant-containers). Not doing it on the main-c will create pb for it to run, but you will not be able to join it from the pi.

2. The IP given on the pi-container should be the one of the main-container. Not sure if its the case in your example.

You can give a look at the open-source project startJade that intends to offer several running examples. The "Platform creation" example covers this case.
