RequestServer.java (1.0)

class RequestServer extends CyclicBehaviour {

protected ACLMessage makeReply(ACLMessage msg) {
String info = msg.getContent();
System.out.println("content = " + info);
ACLMessage reply = msg.createReply();
reply.setPerformative(ACLMessage.INFORM);
reply.setContent("hello from " + myAgent.getLocalName());
return reply;
}


public RequestServer(Agent a) { super(a); }
public RequestServer() { }

public void action() {
ACLMessage msg = myAgent.receive();
if (msg != null) myAgent.send(makeReply(msg));
block();
}
}

ListenerAgent.java

package demos;

import jade.core.*;
import jade.core.behaviours.*;
import jade.lang.acl.*;

public class ListenerAgent extends Agent {

protected void setup() {
System.out.println("Agent " + getLocalName() + " is ready!");
addBehaviour(new demos.RequestServer(this));
}

// put agent cleanup operations here:
protected void takeDown() {
System.out.println(
"Agent " + getLocalName() + " is shutting down");
}
}

Sending messages with the dummy agent

(Hint: Right click in Receivers window)

Sending messages through AMS

public class Sender extends Agent {

protected void setup() {
ACLMessage msg = new ACLMessage(ACLMessage.REQUEST);
msg.setContent( "Help me" );
msg.addReceiver( new AID( "phil", AID.ISLOCALNAME) );
send(msg);
msg= blockingReceive();
if (msg!=null)
System.out.println( "Answer: "
+ msg.getContent() + " from "
+ msg.getSender().getName() );
doDelete();
}
}

Output

Agent phil is ready!
content = Help me
Answer: hello from phil from phil@DELL-LAPTOP2:1099/JADE
