我照着《VRML与Java编程技术》，写了这样的一个程序，但是没效果出来

请高手们指教啊！！！

vrml文件：

ROUTE Touch1.isActive TO openWnd.clicked

ROUTE Touch2.isActive TO openWnd.clicked2

Java窗体程序：

import java.awt.*;

import javax.swing.*;

public class TheFirstWindow extends Frame{

public static void main(String args[]){

TheFirstWindow opp = new TheFirstWindow();

opp.show();

opp.resize(500,400);

opp.setTitle("我的窗口");

}

public TheFirstWindow(){

Label labely = new Label("欢迎进入我的第一个窗口",Label.LEFT);

add(labely);

Panel pp = new Panel();

pp.add(new Button("打开"));

pp.add(new Button("关闭"));

pp.add(new Button("更多内容"));

pp.setBackground(Color.red);

add(pp);

Panel p = new Panel();

p.add(new TextArea("",6,25));

p.add(new Button("保存"));

p.add(new Button("我要留言"));

p.add(new Button("全部删除"));

p.setBackground(Color.green);

setLayout(new FlowLayout());

add(p);

}

public boolean handleEvent(Event e){

TextField t = new TextField();

switch(e.id){

case Event.WINDOW_DESTROY:

dispose();

System.exit(0);

default:

return super.handleEvent(e);

}

}

}

与vrml通信的程序：

import vrml.*;

import vrml.field.*;

import vrml.node.*;

public class layOut extends Script{

TheFirstWindow myWindow;

public void initialize()

{

myWindow = new TheFirstWindow();

}

public void processEvent(Event e)

{

ConstSFBool v = (ConstSFBool)e.getValue();

if(v.getValue())

{

if(e.getName().equals("clicked") == true)

{

myWindow.show();

}

else

{

myWindow.hide();

}

}

}

}
