[英]JADE agents - Exception message: Dispatcher error - Caused by: DispatcherException in remote site. No skeleton for object-id
I'm attempting setup 2 agents(DFSearchAgent) and another agent that registers a service by type (DFRegisterAgent).我正在尝试设置 2 个代理(DFSearchAgent)和另一个按类型注册服务的代理(DFRegisterAgent)。
However, I cannot launch "peripheral container" or an extra container that hosts a 2nd agent.但是,我无法启动“外围容器”或托管第二个代理的额外容器。
Assumptions:假设:
Initially, I launch DFSearchAgent and DFRegisterAgent in the same "MainController" using the JADE GUI options with steps: , right click, MainContainer, chose "Start New Agent", then selected DFSearchedAgent from the pre-packaged examples:最初,我使用 JADE GUI 选项在同一个“MainController”中启动 DFSearchAgent 和 DFRegisterAgent,步骤如下: ,右键单击 MainContainer,选择“Start New Agent”,然后从预打包的示例中选择 DFSearchedAgent:

Now to the problem...现在问题...
If I re-attempt the above steps, however with two different containers 1 MainContainer and 1 peripheral, then I get an exception (DispatcherException in remote site. No skeleton for object-id).如果我重新尝试上述步骤,但是使用两个不同的容器 1 MainContainer 和 1 个外围设备,那么我会得到一个异常(远程站点中的 DispatcherException。没有 object-id 的骨架)。
Attempt #1 (Using 1 Main-Container, 1 Peripheral Container, same machine) Steps:尝试#1(使用1个主容器,1个外围容器,同一台机器)步骤:
OR或者

关闭旧容器并通过 java

Launch 2nd peripheral container via command line run:通过命令行运行启动第二个外围容器:

Attempt 4 (via code):尝试 4(通过代码):
I also attempt the same steps by setting up Java projects and instantiating the DFRegisterAgent and register (DFRegisterAgent in 1 MainContainer & instantiating the DFSearchAgent and register DFSearchAgent in 2 MainContainer.我还尝试通过设置 Java 项目并实例化 DFRegisterAgent 并注册(DFRegisterAgent 在 1 MainContainer 中并实例化 DFSearchAgent 并在 2 MainContainer 中注册 DFSearchAgent)来尝试相同的步骤。
Register the DFRegisterAgent:注册 DFRegisterAgent:
package com.example.yellowpages;
import jade.util.leap.*;
import jade.core.Profile;
import jade.core.ProfileImpl;
import jade.wrapper.*;
/**
* Hello world!
*/
public final class App {
private App() {
}
/**
* Says hello to the world.
* @param args The arguments of the program.
*/
public static void main(String[] args) {
System.out.println( "Start test..." );
Properties pp = new Properties();
pp.setProperty(Profile.GUI, Boolean.TRUE.toString());
Profile p = new ProfileImpl(pp);
jade.wrapper.AgentContainer ac = jade.core.Runtime.instance().createMainContainer(p);
try {
ac.acceptNewAgent("DFRegisterAgent",new DFRegisterAgent()).start();
} catch (StaleProxyException e) {
throw new Error(e);
}
System.out.println( "Test is complete..." );
}
}
Register DFSearchAgent:注册 DFSearchAgent:
package com.example.yellowpages;
import jade.util.leap.*;
import jade.core.Profile;
import jade.core.ProfileImpl;
import jade.wrapper.*;
/**
* Hello world!
*/
public final class App {
private App() {
}
/**
* Says hello to the world.
* @param args The arguments of the program.
*/
public static void main(String[] args) {
System.out.println( "Start test..." );
Properties pp = new Properties();
pp.setProperty(Profile.GUI, Boolean.TRUE.toString());
Profile p = new ProfileImpl(pp);
jade.wrapper.AgentContainer ac = jade.core.Runtime.instance().createMainContainer(p);
try {
ac.acceptNewAgent("DFSearchAgent",new DFSearchAgent()).start();
ac.acceptNewAgent("DFSubscribeAgent",new DFSubscribeAgent()).start();
} catch (StaleProxyException e) {
throw new Error(e);
}
System.out.println( "Test is complete..." );
}
}
I ran 2 programs, in 2 separate shell windows (1st ran the DFRegisterAgent, then the DFSearchAgent) using:我在 2 个单独的 shell windows 中运行了 2 个程序(第一次运行 DFRegisterAgent,然后是 DFSearchAgent),使用:
java -cp target/demo-1.jar com.example.yellowpages.App java -cp target/demo-1.jar com.example.yellowpages.App
1st console output snippet:第一个控制台 output 片段:
Agent container Main-Container@137.79.225.104 is ready.
--------------------------------------------
Test is complete...
Agent DFRegisterAgent registering service "unknown" of type "weather-forecast"
2nd console output snippet:第二个控制台 output 片段:
INFO: --------------------------------------
Agent container Main-Container@137.79.225.104 is ready.
--------------------------------------------
Agent DFSearchAgent searching for services of type "weather-forecast"
Test is complete...
Agent DFSearchAgent did not find any weather-forecast service
Looking at the GUI, both agents were registered.查看 GUI,两个代理都已注册。
The agents cannot see each other, when the agents are registered in separate containers & I cannot launch a peripheral container as a workaround.当代理在单独的容器中注册并且我无法启动外围容器作为解决方法时,代理无法看到彼此。
How can I fix the search agent to find a registered agent?如何修复搜索代理以找到注册代理?
Appreciated.赞赏。
The error you report occurs when you launch a peripheral container without a main already active.当您启动外围容器时,会出现您报告的错误,而主容器尚未处于活动状态。 Be sure your main is up and running before starting the peripheral container with the search agent on top.
在启动外围容器之前,请确保您的 main 已启动并运行,搜索代理位于顶部。
Bye,再见,
