A simple example using 2 agents one of them with a Java class

This examples shows 2 Jason agents interacting by internal messages and one of them has a Java class where an interface is shown. The user can interact with the agents by a button.

This project can run in Eclipse using JasonIDE plugin of by JEdit.

Project code (project.mas2j file):
MAS jasonEmbedded {
infrastructure: Centralised
agents:
a1;
a2 agentArchClass agent2;
aslSourcePath:
"src/asl";
}

Agent1 code (a1.asl file):
!start.

+!start : true 
<- .print("Hello, I am here!").

+!goalPerformed[source(X)] : true

<- .send(X, achieve, beReady).

Agent2 code (a2.asl file):

!start.

+!start : true 

<- .print("Hello, I am here!").

@doSomething

+!doSomething : true   // this goal is created by the GUI of the agent 

<- .print("Agent 2 is performing something.");

.send(a1, achieve, goalPerformed).

    

@beReady

+!beReady : true

<- .print("I am ready for the next task!").

Agen2 java class (agent2.java file):

import java.awt.BorderLayout;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import jason.architecture.*;

import jason.asSyntax.ASSyntax;

import jason.asSyntax.Literal;

import javax.swing.*;

/** example of agent architecture's functions overriding */

public class agent2 extends AgArch {

  JTextArea jt;

  JFrame f;

  JButton button;

  public agent2() {

    jt = new JTextArea(10, 30);

    button = new JButton("Perform goal 1");

    button.addActionListener(new ActionListener() {

      public void actionPerformed(ActionEvent e) {

        Literal goal = ASSyntax.createLiteral("doSomething");

jt.append("\n\rPerforming goal 1...");

getTS().getC().addAchvGoal(goal, null);

      }

    });

    f = new JFrame("Agent2");

    f.getContentPane().setLayout(new BorderLayout());

    f.getContentPane().add(BorderLayout.CENTER, new JScrollPane(jt));

    f.getContentPane().add(BorderLayout.SOUTH, button);

    f.pack();

    f.setVisible(true);

  }

  @Override

  public void stop() {

    f.dispose();

    super.stop();

  }

}
