Eclipse3.2.1中不能连接MySQL数据库

Question

我使用Eclipse3.2.1（WTP）+Spring2.0+Hibernate3编写一个很简单的数据库访问的WEB程序，数据库用的是MySQL5.0，spring.jar和mysql-connector-java-5.0.0-beta-bin.jar已加入到CLASSPATH中，但在启动TOMCAT后依然出错，调试了很长时间，请各位大虾帮帮忙，看看错在哪里，一定加分！出错信息：

谢谢老兄，我试过，但还是一样的错误。我把web.xml和context.xml贴出来，请帮我看看是不是有问题？

Answer 3

WEB-INF/classmaster-servlet.xml
这个是什么

Answer 4

看到了报的错误就是 找不到 hibernate的jar你的hibernate3 放到什么地方了

Answer 5

在Java Build Path中添加了，也将该文件复制到了WEB-INF\LIB中了。
