Question

我正在尝试在同一主机上生成更多的Jade实例。我知道可以通过cmd行，但是我无法使用某些Java代码来做到这一点。我无法在Java中运行命令行，因为这样一来，我可能会丢失一些有关platfomr的信息。有人可以帮助我吗？在我的代码和错误下方：

public class MainCMD_ {

static String classAgentName= "Agents.MyAgent";
static int agentNum=6;

public static void main(String[] args) throws IOException {
    // TODO Auto-generated method stub
    String platformHost= "localhost";
    String platformName="Platform_";
    int platformPort= 2000;


    for (int i =1; i<3;i++) {
        platformName="Platform_"+i;
        while(!isAvailablePort(platformPort)){
            platformPort++;
        }

        //new jade.Boot3(new String[] {"-local-host",platformHost,"-local-port",Integer.toString(platformPort),"-name",platformName,"-gui"}); 
        genPlatform(platformHost,platformName,platformPort);

        System.out.println("Platform "+platformName+" created!"); 

    }
}


private static void genPlatform (String platformHost, String platformName, int platformPort) {

    Runtime runtime = Runtime.instance();

    ProfileImpl profile = new ProfileImpl(); 

    profile.setParameter(Profile.PLATFORM_ID, platformName); 
    profile.setParameter(Profile.LOCAL_HOST, platformHost); 
    profile.setParameter(Profile.LOCAL_PORT, Integer.toString(platformPort)); 
    profile.setParameter(Profile.GUI, "true");
    profile.setParameter(Profile.MAIN, "false");
    //profile.setParameter(Profile.CONTAINER_NAME, "MainContainer");
    //System.out.println(profile.getProperties());

    ContainerController cc = runtime.createMainContainer(profile);  

    AgentController ac;

    for(int i = 1; i<agentNum;i++) {
    try {
        ac=cc.createNewAgent("MyAgent"+i, classAgentName, null);
        ac.start();

    } catch (StaleProxyException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    }
}


private static boolean isAvailablePort(int port) {
    //metodo per verificare che la porta sia disponibile

        ServerSocket ss = null;
        DatagramSocket ds = null;
        try {
            ss = new ServerSocket(port);
            ss.setReuseAddress(true);
            ds = new DatagramSocket(port);
            ds.setReuseAddress(true);
            return true;
        } catch (IOException e) {
        } finally {
            if (ds != null) {
                ds.close();
            }
            if (ss != null) {
                try {
                    ss.close();
                } catch (IOException e) {
                }
            }
        }
        return false;

    }
}

Answer 1

关于您的最后一个问题：是的，有可能。

假设您使用Eclipse，则可以有两个（或更多）Run Configurations。每个配置的参数部分都应不同（对应于main方法中的args数组）。使用这些参数，您应该能够区分平台及其配置。

正如Runtime.instance();访问指示的那样，通过代码进行的JADE平台处理由Singleton实现。因此，一个JVM中将不能拥有多个JADE平台。使用上述方法，每个运行配置将产生一个JVM，并且您确实可以发送ACL消息，而不是在平台上移动消息（如果要在同一平台的代理之间发送消息，JADE不会序列化/反序列化消息）

希望这会有所帮助！
