[jade-develop] agent communication

[fatma chamekh]

Hi all,
I am a little bit confused in the way to send message between agent. I
think there is two differents way : if agents are in the same container, or
if they are in differents containers.
should i use the same code in each case
like for exemple :(sure after registration in DF)

sender
ACLMessage msg = new ACLMessage(ACLMessage.INFORM);

msg.addReceiver(tet2o);
msg.setLanguage("StringLanguage");

msg.setContent(res.getLabel().toString());
msg.setDefaultEnvelope();

Receiver
ACLMessage msg = blockingReceive();
if (msg!=null System.out.println(getLocalName()+ " rx
msg"+msg.getContent());

I tried those instructions, it doesn't work.
I don't know what is wrong.
Thanks

Hi,

Yes! From the programming point of view communication is fully transparent with respect to the fact that the agents are in the same or in different containers.
Of course I suppose in the sender code you also call send(msg) ☺.

What do you mean by “it doesn’t work”?

You can use the Sniffer and the Introspector tools to investigate the problem:
The former lets you know if the message was actually delivered from the sender to the receiver.
The latter lets you see if the message is still pending in the receiver’s message queue.

Bye,

Giovanni

P.S. If you are dealing with agents living in different containers of the same platform and unless you have special requirements you don’t need to deal about the message Envelope --> msg.setDefaultEnvelope() is useless.
