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：

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();
}
}
}
}
