ERROR org.springframework.web.context.ContextLoader:224 - Context initialization

[winner_xyz]

java.lang.NoClassDefFoundError: org/hibernate/MappingException

Caused by: java.lang.ClassNotFoundException: org.hibernate.MappingException

Struts2.1+Spring3.0+hibernate3.3 。配完spring+ hibernate 后一切正常。但是加入STRUTS 后，一起动TOMCAT 就报以上异常，
但是单独用junit测试 方法仍能允许。
