------解决方案--------------------
这个是类没找到，也就是jar包问题。你hibernate用的是4点几
------解决方案--------------------
还有一种可能，就是你的服务器jre版本。系统jre、MyEclipse、中间件服务器jer必须一致。否则可能导致这种运行时java.lang.NoClassDefFoundError
------解决方案--------------------
你的jar包都加全了吗？
------解决方案--------------------
java.lang.NoClassDefFoundError: org/hibernate/service/jndi/JndiNameException 检查下hibernate Jar 中有没有这个class类
再就是2楼说的那种情况了，有可能是jdk版本，struts，spring以及log4j 等的版本不配套导致的
先检查下有没有那个class，然后检查配套jar包的匹配问题
------解决方案--------------------
org/hibernate/service/jndi/JndiNameException这个类应该在hibernate-core4.jar里，看你使用的jar是否是一个系列的版本。
------解决方案--------------------
spring是个大坑，别用为好
------解决方案--------------------
hibernate-core.jar这个jar用4.2试试
------解决方案--------------------
jar包弄进来了么 很有可能是jar包的版本不对
