根据这条线：

 Caused by: java.lang.ClassNotFoundException: org.hibernate.Query

我认为servlet找不到hibernate jar库

这是我的servlet结构DataServlet.java是我的servlet类：

我还将所有需要的jar复制到WEB-INF/lib中

我错在哪里

 EDIT : I SOLVED THE PROBLEM, ONE FILE WAS MISSING WHEN ADDED TO WEB-INF/lib.

你能分享一下你添加的jar名称吗。这将是一个容易理解的问题。除了一些可选的JAR之外，几乎所有的JAR都是从Hibernate下载的。当我以Java应用程序的形式运行演示时，它运行得很好，所以我认为我没有添加错误的JAR。。。。所以我想我没有加错罐子。证据表明情况并非如此。我大胆猜测。。。您只从第三方依赖项所在的lib目录添加了jar，这就是Eclipses编译时类路径。战争是什么？提供一些关于您正在部署的WAR中的WEB-INF/lib目录内容的直接证据。
