hiberante提示找不到类
我在jsp中使用hiberante,但是报一下错误:

我以为是hibernate3.jar没有导入项目的原因,查了一下是导入了的,而且我在项目里写了个类,在main方法里测试就是正常的把数据保存到数据库,只有在jsp中才会出现这个问题。请问是怎么回事?

------解决方案--------------------
是WEB项目部署的问题,运行JSP的时候应该是你的web-inf/lib下面没有hibernate的相关jar包所以在单机调试可以但是在web运行找不到
楼主把你工程相关的jar包都放到web-inf/lib这个目录下,然后启动tomcat,看看浏览对应页面的时候是不是正常了?
