hibernate报错?

[libd2319]

我的hibernate运行到这句就报错
sessionFactory=new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();

错误信息:
java.lang.ExceptionInInitializerError
All.HibernateUtil.<clinit>(HibernateUtil.java:28)
com.toshiba.servlet.addminRegisterServlet.doPost(addminRegisterServlet.java:71)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)


hibernate.cfg.xml文件:
<?xml version='1.0' encoding='UTF-8'?>
