@H_502_1@我有一个使用gwt-maven-archetype构建的Maven项目.虽然它与mvn gwt：run目标运行完美,但是当我尝试在tomcat7容器中运行它时mvn tomcat：run或mvn gwt：compile&& mvn tomcat：运行它不加载GWT动态创建的小部件.
根据谷歌Chrome控制台,它找不到* .nocache.js文件,即使在/ target /文件夹中它正好在预期的位置.
我目前正在尝试在入口点模块中显示一个简单的“Hello”标签：
GWT入口点
public class Hello implements EntryPoint {
public void onModuleLoad() {
Label hello = new Label("TESTESTSTSTS");
RootPanel.get("helloContainer").add(hello);
}
}

解决方法
tomcat7：run只使用src / main / webapp.你将要使用tomcat7：run-war(将执行一个包)或tomcat7：run-war-only(如果你已经有一个war：爆炸结构).
