我正在通过rmi创建桌面共享小工具，除了它不响应关键事件之外，每件事都很好。我不明白我缺少的地方..
这是服务器代码..
public class ServerInterface extends UnicastRemoteObject implements System_Behav {
private static final long serialVersionUID = 1L;
public static Robot robo=null;
public static int height;
public static int width;
protected ServerInterface() throws RemoteException {
super();
}
public static void main(String[] args) {
// TODO Auto-generated method stub
if(System.getSecurityManager()==null)
System.setSecurityManager(new RMISecurityManager());
height=Toolkit.getDefaultToolkit().getScreenSize().height;
width=Toolkit.getDefaultToolkit().getScreenSize().width;
try{
System_Behav system_server=new ServerInterface();
Registry r=LocateRegistry.createRegistry(1099);
r.bind("system_server", system_server);
GraphicsEnvironment g=GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd=g.getDefaultScreenDevice();
robo=new Robot(gd);
System.out.println("server bound");
}catch(Exception e)
{
System.err.println("Computeappengine exception"+e.getMessage());
e.printStackTrace();
}
}
public void MouseMove(int x,int y,int w,int h) throws RemoteException {
// TODO Auto-generated method stub
x=x*(height/h);
y=y*(width/w);
robo.mouseMove(x, y);
}
public void Mousepress(int a) throws RemoteException {
// TODO Auto-generated method stub
robo.mousePress(a);
}
public void MouseRelease(int a) throws RemoteException {
// TODO Auto-generated method stub
robo.mouseRelease(a);
}
@Override
public void KeyPress(int a) throws RemoteException {
robo.keyPress(a);
}
@Override
public void KeyRelease(int a) throws RemoteException {
// TODO Auto-generated method stub
robo.keyRelease(a);
}
@Override
public byte[] getScreen() throws RemoteException {
Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
Rectangle rectangle = new Rectangle(dim);
BufferedImage bi= robo.createScreenCapture(rectangle);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
try {
ImageIO.write(bi, "PNG", bytes);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return bytes.toByteArray();
}
}
这是客户端代码
public class ClientInterface{
/**

private static final long serialVersionUID = 1L;
public static JPanel contentPane;
public static System_Behav sb=null;
/**

*/
public static void main(String[] args) {

System.setSecurityManager(new RMISecurityManager());
try{

sb=(System_Behav)Naming.lookup(name);
try {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
frame.setContentPane(contentPane);
frame.setVisible(true);
new screen(contentPane,sb);
new command(contentPane,sb);
} catch (Exception e) {
e.printStackTrace();
}
}catch(Exception e)

System.err.println("Computeappengine exception"+e.getMessage());
e.printStackTrace();
}
}
