Java rmi聊天室无法向服务器发送数据

我正在开发一个带有GUI的rmi聊天室。我必须从客户端获取输入并将其发送到服务器。但我无法使用从Jtextfield读取的值。有谁能帮助我如何使用用户的读取输入发送到服务器

import java.applet.Applet;
import java.awt.*
import java.rmi.Naming;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import javax.swing.*;

public class MyChatClient extends UnicastRemoteObject{

     JFrame F = new JFrame("Chat room");
 JTextField T = new JTextField(25); 
 JPanel pane = new JPanel(new GridBagLayout());
 JButton B = new JButton("submit");
 JPanel pane2 = new JPanel(new GridBagLayout());
 TextArea TA = new TextArea(15,50);
 String response;

protected  MyChatClient() throws RemoteException {


    F.setSize(400,400);
    pane.add(T);
    pane.add(B);
    F.add(pane, BorderLayout.SOUTH);

    TA.setEditable(false);
    TA.setBackground(Color.WHITE);

    pane2.add(TA);
    F.add(pane2, BorderLayout.BEFORE_FIRST_LINE);
    F.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    F.setVisible(true);


        B.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e) {
                response = T.getText();  // I am not able to send this to server                                                                  

             }});
    }

   public static void main(String[] args) throws RemoteException {

    MyChatClient mc = new MyChatClient();
    try{
        //System.setSecurityManager(new RMISecurityManager());
        //Registry reg = LocateRegistry.getRegistry("localhost");

       ServerImpl svr = (ServerImpl)Naming.lookup("rmi://localhost/ChatServer") ;
                    System.out.println("Server found"); 
             svr.sendMessage(response); // here is the problem

     }catch(Exception e){
        System.err.print(e);
    }

    }

 }

我想你的行动听众永远不会被召唤。试着检查一下

B.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e) {
                response = T.getText(); 
                System.out.println("inside action");                                                 

             }});

或者添加一个按钮并在其click事件中执行此操作。祝你好运

看起来您是在问如何延迟调用

sendMessage

，直到调用

actionPerformed

之后。这就是你的问题所在，还是我误解了？即使是tat也会发问，但我必须从textfield中阅读并将其发送到服务器这里的问题是什么？如何从JTextField中获取数据？我需要将在textfield中输入的数据保存到一个变量中，然后发送到服务器，问题是？
