我想在同一台PC上使用JADE将一个代理程序的文件发送给另一个代理程序。这里执行期间会出现一些错误。

接收方：通过使用JADE从发送代理接收文件

package sendmessage;

import jade.lang.acl.MessageTemplate;
import java.io.File;

/**

public class B extends Agent {

    protected void setup() {
        this.addBehaviour(new MyBehaviour(this));
    }

    private static class MyBehaviour extends Behaviour {
        MessageTemplate mt = MessageTemplate.MatchPerformative(ACLMessage.REQUEST);
        public MyBehaviour(B aThis) {

        }

        @Override
        public void action() {
//            ACLMessage acl = myAgent.receive(mt);
//            if (acl!= null) {
//                System.out.println(myAgent.getLocalName()+ " received a message: "+acl.getContent());
//                ACLMessage rep = acl.createReply();
//                rep.setPerformative(ACLMessage.INFORM);
//                rep.setContent("ok, i received a message!");
//                myAgent.send(rep);

        ACLMessage msg = receive("Yes Received your file");
                if (msg != null) {
                  String fileName = msg.getUserDefinedParameter("a.txt");
                  File f = "a.txt"; // create file called fileName
                  byte[] fileContent = msg.getByteSequenceContent();
                  // write fileContent to f
                }
             else {
                this.block();
            }
        }
        @Override
        public boolean done() {
            return false;
        }
    }
}

如果您打算在周围交换文件，可能需要为您的代理系统创建一个Ontology。 JADE提供了使用OntologyBean类作为代理通信方法（真正简化事物）的表示的能力。

BeanOntology类以谓词，概念等形式添加自定义语言。在这些自定义语言描述中，您可以放置一个对象以及您可能希望与其一起指定的任何其他信息。如果您按照JADE提供的文档进行操作实际上非常简单 - ＆gt; tutorial here

祝你好运！
