基於無線通信從基於Web的應用基於桌面的應用

我的工作它由兩個部分的應用的一個基於Web的和其他的桌面應用程序，基於Web的應用程序將桌面呼叫應用兩種機器都在局域網。應用程序是用Java編寫的。有人建議我使用RMI。當基於Web的應用程序會像RMIClient和桌面應用程序會爲RMIServer。基於Web的應用程序，我們使用Spring框架Spring provied爲RMI服務以自己的方式在內部使用的Java RMI。我決定根據這種模式進行原型設計。基於無線通信從基於Web的應用基於桌面的應用

我現在已經創建了RMIClient使用Spring請參閱下面的代碼： -

package com.rmi.client; 
import org.springframework.context.ApplicationContext; 
import org.springframework.context.support.ClassPathXmlApplicationContext; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
@Controller 
public class MainController { 

@RequestMapping("/callrmiserver") 
public void callRMISever(){ 
    ApplicationContext ctx = new ClassPathXmlApplicationContext("ServiceBean.xml"); 
    System.out.print("before getbean"); 
    Hello hello = (Hello) ctx.getBean("helloService"); 
    System.out.print("i am greeting from "+hello.greeting()); 
    } 

}

ServiceBean.xml文件是這樣的：

<?xml version="1.0" encoding="UTF-8"?> 
    <beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:p="http://www.springframework.org/schema/p" 
xmlns:context="http://www.springframework.org/schema/context" 
xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 

<bean id="Helloservice" class="org.springframework.remoting.rmi.RmiProxyFactoryBean"> 
    <property name="serviceUrl" value="rmi://localhost:1009/Services" /> 
    <property name="serviceInterface" value="com.rmi.client.Hello" /> 
</bean>

界面是這樣的：

package com.rmi.client; 

public interface Hello { 
    String greeting(); 
}

桌面基礎的RMIServer就像

package rmiapplication; 
import java.net.MalformedURLException; 
import java.rmi.Naming; 
import java.rmi.RemoteException; 
import java.rmi.registry.LocateRegistry; 
public class RMIServer { 
    public static void main(String[] args) throws RemoteException, MalformedURLException { 
     System.out.println("server conf..."); 
       LocateRegistry.createRegistry(1009); 
       Hello hello = new HelloImpl(); 
       Naming.rebind("Services", hello); 
       System.out.println("server.RMI Server is ready."); 
     } 

    }

方法的實現部分是： -

package rmiapplication;

進口java.rmi.RemoteException異常; 進口java.rmi.server.UnicastRemoteObject;

公共類HelloImpl擴展了UnicastRemoteObject實現您好{

private static final long serialVersionUID = 6789759288861838122L; 

public HelloImpl() throws RemoteException { 
    } 

    public String greeting() throws RemoteException { 
     System.out.print("i am at server side call"); 
     return "greeting"; 
    } 

    }

當我運行是整個安裝，先從rmiregistry中，爲RMIServer然後基於Web的應用程序我在這裏得到java.rmi.NotBoundException充滿堆棧跟蹤： -

現在，我不知道是什麼讓錯誤在這方面，我曾嘗試谷歌，但我已經在此基礎上

點的問題沒有得到任何成功的現在

如何刪除上述異常，我也試過用局域網中的不同機器
什麼是我們最好的方式從基於Web的應用程序觸發桌面應用程序，以便它開始執行。完整的問題陳述是我們有一個基於Web應用程序和本地計算機

謝謝您對遵守代碼運行運行編譯器，

我得到了解決，如果有人面臨着與春天的Web應用程序的任何問題並使用RMI非簧桌面應用程序通信寄給我

感謝您對社區的支持

發現有一些情況下春天服務器和非簧客戶端通過RMI創建問題。但是這是可能的，當你使用非彈性的服務器和客戶端的彈簧（Web服務器到桌面應用程序）。在我的情況，而使用

這裏有問題就是我的客戶

public void getRMIServer(){ 
    Registry registry = null; 
    Hello stub; 
    try { 
     System.out.println("IN RMI CLients"); 
     registry = LocateRegistry.getRegistry("localhost"); 
     stub = (Hello) registry.lookup("yash"); 
     System.out.println(stub.greeting()); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
}

這裏是我的服務器

public static void main(String[] args){ 
    try { 
     System.out.println("RMI Server Started"); 
     HelloImpl hello = new HelloImpl(); 
     UnicastRemoteObject.unexportObject(hello, true); 
     Hello stub = (Hello) UnicastRemoteObject.exportObject(hello, 0); 
     Registry reg = LocateRegistry.createRegistry(1098); 
     reg.rebind("yash", stub); 
     System.out.println("server.RMI Server is ready."); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

}

我們還需要共享的資源，將駐留在服務器和客戶端上的是什麼但通用接口

package shared; 
import java.rmi.Remote; 
import java.rmi.RemoteException; 
import java.util.Map; 
    public interface Start extends Remote{ 
    public void startRMI(Map<Object,Object> m) throws RemoteException; 
    public void stopRMI() throws RemoteException; 
}

共享資源是接口，即分機結束遠程接口

如果工作需要有人解決方案，請讓我知道
