请问高手！用STRUTS+HIBERNATE编写登陆程序时出现“java.lang.NoClassDefFoundError: org/hibernate/Session”，加上MAIN函数单独运行可

Question

WEB-INF/lib
有hibernate的jar文件没？

Answer 1

把Hibernate3的jar包考到WEB-INF/lib下

Answer 2

有的，加main{}单独测试没有问题。用JSP页面结合STRUTS就找不到了。

Answer 3

我把代码注释掉，剩下Configuration c=new Configuration();，也报错，把Hibernate3的jar包考到WEB-INF/lib下了。
