hibernate无法初始化
第一次用hibernate，运行时报错hibernate无法初始化，找不到问题所在，求高手指点

严重: Servlet.service() for servlet jsp threw exception
java.lang.NoClassDefFoundError: Could not initialize class ielab.hibernate.HibernateSessionFactory

------解决方案--------------------
贴点代码吧。这些配置按照书上的步骤的话，就不会有错了。
------解决方案--------------------
HibernateSessionFactory没有实例化啊
------解决方案--------------------
检查一下ielab.hibernate.HibernateSessionFactory是不是包含在包中。
把HibernateSessionFactory的代码贴出来看看，可能初始化是报错了，导致Could not initialize class。把初始化代码加上try catch试试
------解决方案--------------------
java.lang.NoClassDefFoundError: Could not initialize class ielab.hibernate.HibernateSessionFactory

没有找到类定义啊 ？

看看在那个jar包里的，是否把jar放到项目 ，或者是否jar包冲突 ？
------解决方案--------------------
我也是刚学Hibernate的，来关注一下……
