gwt集成Hiberater不能用Google App Engine启动

 

将GWT编译后的代码直接放到Tomcat中可以连接数据库，但是在Google App Engine运行会报以下错误：

java.lang.NoClassDefFoundError: java.net.Socket is a restricted class. Please see the Google  App Engine developer's guide for more details.

 选择项目右键->Google->App Angine Settings...->Use Google App Engine复选框，把对勾给去掉，就可以了
