Jboss服務器中的RMI部署

Question

我想使用Jboss RMI（或JNDI）端口1099部署RMI。當Jboss服務器不在圖片中時（即使用主程序），每件事情都正常工作。爲了部署在服務器上，我嘗試了兩種方法。

1）獲取Jboss註冊表端口並將RMI註冊表綁定到該端口。 以下是我已經寫在servlet的 的init方法的代碼（這裏服務器是我的接口，擴展Remote，ServerImplementor是類實現服務器）

 

    public void init() throws ServletException { 
      { 
      Server implementor=new ServerImplementor(); 
      Remote obj = UnicastRemoteObject.exportObject(implementor, 0); 
      Registry r=LocateRegistry.getRegistry(); 
      System.out.println("Registry post::"+r.REGISTRY_PORT); 
      r.bind("TestRMI", obj); 
      } 
      catch(Exception e) 
      { 
       e.printStackTrace(); 
      } 
     } 

這種方法的問題是，當我運行客戶端用下面的代碼：

 

    registry = LocateRegistry.getRegistry("localhost",1099); 
      hello = (Server) (registry.lookup("TestRMI")); 

The error which i get is: java.rmi.ConnectIOException: non-JRMP server at remote endpoint 

2) The 2nd approach which i tried is using JNDI, exposing a RMI(This is one approach which i came to know through googling) 
Following is the code for the init method of servlet.Here the protocol used is jnp 

 

    try { 
      Server remoteObj=new ServerImplementor(); 
      Properties properties=new Properties(); 
      properties.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); 
      properties.put("java.naming.provider.url", "jnp://localhost:1099"); 
      properties.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces"); 

      InitialContext initialContext=new InitialContext(properties); 
      initialContext.rebind("TestRMI", remoteObj); 
      System.out.println("server up"); 

     } catch (RemoteException e) { 
      e.printStackTrace(); 
     } 
     catch(NamingException n) 
     { 
      n.printStackTrace(); 
     } 

When i run the client for the 2nd approach it gives error "TestRMI is not bound" 
    Client code is: 

 

    main(){ 
         Properties properties=new Properties(); 
      properties.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); 
      properties.put("java.naming.provider.url", "jnp://localhost:1099"); 
      properties.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces"); 
      InitialContext initialContext=new InitialContext(properties); 
      Server server=(Server)PortableRemoteObject.narrow(initialContext.lookup("TestRMI"), Server.class); 
    } 

So, i am not able to figure out what is the correct approach for deploying RMI in Jboss. Is it correct to write code in Servlet init method and create a registry.Or we have to use EJB,etc.. If any one have done this before please help me. 

Thanks

您可以檢查端口1099是否存在。 也許，港口已經被捆綁起來了。 嘗試通過以下方式指定端口：

LocateRegistry.createRegistry(port);
