跪求gwt缺少继承的错误提示
错误提示:
[ERROR] [hellogwt] - Unable to load module entry point class chapter2.client.HelloGWT (see associated exception for details)
[ERROR] [hellogwt] - Failed to load module 'hellogwt' from user agent 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; SE 2.X MetaSr 1.0)' at localhost:2486
public class HelloGWT implements EntryPoint {
@SuppressWarnings("deprecation")
public void onModuleLoad() {
//显示Body
Window.alert(RootPanel.get().getElement().getTagName());
RootPanel divrootPanel = RootPanel.get("div1");
//显示div
Window.alert(divrootPanel.getElement().getTagName());
//显示Input
//Window.alert(divrootPanel.getElement().getInnerHTML());

------解决方案--------------------
我也刚接触GWT 没多久，我试试给点提醒。
1. SDK 是否下载，并用eclipse 引入到classpath 里面。
2. 在helloGWT.gwt.xml 里面<inherits name='chapter2.HelloGWT'/>，这句好像是多余的。
你再试试看，希望有机会多多探讨
------解决方案--------------------
还有就是别往设置JAVA_HOME, 当然一般这个大家都懂得，就怕是忘了，或是什么的
