大家好!

请教大家一个问题!我在运行gwt-ext中的例子时报错!程序:

package cn.itcast.button.client;

import com.google.gwt.core.client.EntryPoint;

import com.google.gwt.user.client.ui.RootPanel;
import com.gwtext.client.widgets.CycleButton;
import com.gwtext.client.widgets.Panel;
import com.gwtext.client.widgets.event.CycleButtonListenerAdapter;
import com.gwtext.client.widgets.menu.CheckItem;

public class TestButton implements EntryPoint{

public void onModuleLoad(){
Panel panel = new Panel();
panel.setPaddings(5);
panel.setBorder(false);

CycleButton button = new CycleButton();
button.setShowText(true);
button.setPrependText("View as");

button.addItem(new CheckItem("text only",true));
button.addItem(new CheckItem("HTML",false));

button.addListener(new CycleButtonListenerAdapter(){
public void onChange(CycleButton self,CheckItem item){
System.out.println(item.getText()+" selected.");
}
});
panel.add(button);

RootPanel.get().add(panel);
}
}

运行时刚开始时是找不到网页,报404找不到TestButton.html的页面,而且我明明是有这个页面的,过了一段时间重新打开项目,又是报其他的错误,真是令人费解,不知道原因到底出在哪里!望各位高手不吝赐教!报错信息:
