JADE: installation and “Hello World” application Fabiano Dalpiaz Agent-Oriented Software Engineering (AOSE)

F. Dalpiaz - AOSE 2009 What is JADE? JADE - Java Agent DEvelopment Framework is a framework to develop and run multi-agent systems in compliance with the FIPA specifications. – Developed by Telecom – Distributed under LGPL Can be downloaded from Free registration is required

F. Dalpiaz - AOSE 2009 Again, what is JADE? Agents JADE

F. Dalpiaz - AOSE 2009 Where can I find help? JADE administrator guide JADE programmer guide Examples & tutorials The JADE book Developing Multi-Agent Systems with JADE Fabio Bellifemine, Giovanni Caire, Dominic Greenwood Editor: WILEY ISBN:

F. Dalpiaz - AOSE 2009 Main features of JADE JADE is a middleware that facilitates the development of multi-agent systems. It includes – A runtime environment where JADE agents can “live” and that must be active on a given host before one or more agents can be executed on that host. – A library of classes that programmers have to/can use (directly or by specializing them) to develop their agents. – A suite of graphical tools that allows administrating and monitoring the activity of running agents.

F. Dalpiaz - AOSE 2009 FIPA-compliance JADE complies with the FIPA standards – FIPA = Foundation for Intelligent Physical Agents – Its standards include: Agent communication (ACL) Agent management Agent message transport Abstract architecture Applications –

F. Dalpiaz - AOSE 2009 JADE distributed architecture Platforms Containers

F. Dalpiaz - AOSE 2009 Containers and Platforms A JADE platform enables agents' execution. Platforms are composed of one or more containers A main container differs from normal containers as it holds two special agents (automatically started when the main container is launched). The AMS (Agent Management System) provides the naming service (i.e. ensures that each agent in the platform has a unique name) and represents the authority in the platform (for instance it is possible to create/kill agents on remote containers by requesting that to the AMS). The DF (Directory Facilitator) provides a Yellow Pages service by means of which an agent can find other agents providing the services he requires in order to achieve his goals.

F. Dalpiaz - AOSE 2009 Agent lifecycle Agents are “born”, “live”, and eventually “die”

F. Dalpiaz - AOSE 2009 Installing JADE 1) Download and install JAVA JDK 2) Go to 3) Register (create your user) 4) Login and download jadeAll.zip 5) Extract jadeAll.zip to a folder (e.g., c:\jade, /home/user/jade) – We will refer that folder JADE_HOME from now on 6) Add the following files to CLASSPATH: –. – JADE_HOME/lib/http.jar – JADE_HOME/lib/iiop.jar – JADE_HOME/lib/jade.jar – JADE_HOME/lib/jadeTools.jar Windows: SET CLASSPATH=%CLASSPATH%;.; c:\jade\lib\http.jar; c:\jade\lib\iiop.jar; c:\jade\lib\jade.jar; c:\jade\lib\jadeTools.jar;

F. Dalpiaz - AOSE 2009 Installing JADE Test your JADE installation: execute java jade.Boot -gui

F. Dalpiaz - AOSE 2009 Did it work? JADE is running properly if this GUI is shown JADE can run without GUI

F. Dalpiaz - AOSE 2009 The JADE GUI anatomy Basic operations on agents: Start Kill Suspend Resume Send Message Migrate Clone Debugging/runtime tools: Sniffer (“interaction spy”) Dummy agent Log Manager Introspector (agents internals) Add platform Active agents

F. Dalpiaz - AOSE 2009 A simple exercise with the GUI TODO: – Repeat the same exercise with two providers – Run the sniffer to monitor what happens da0 da1

F. Dalpiaz - AOSE 2009 Next classes We will cover the main topics of JADE Hands on! – Exercises – Discussion Project assignments – Simulation of a real-life scenario as a multi-agent system – You will receieve detailed specification – Creativity is required to simulate at best – 2-3 members per team – We will give you hints and check the progress of your projects
