jar包有冲突, 应该是XML解析包有冲突. 检查发布后的WEB-INF/lib有两个XML解析包: xml-apis.jar和xerces-2.6.2.jar 这种错误真正原因不是JDK 6和Struts 2冲突, 而是 MyEclipse Hibernate 类库中多了两个包: xml-apis.jar和xerces-2.6.2.jar, 这两个包的功能和JDK的冲突了. 解决办法: 1. 删除发布后目录的 WEB-INF/lib/ 下的这两个文件; 2. 或者使用JDK 1.5来启动Tomcat 6.

这是网上的解答。

这里删除web-inf/lib/下的文件是什么意思,tomcat重新部署后两个文件依然存在啊。若从MyEclipse Hibernate中删除,项目会报错。具体怎么解决,望指点啊。

我也碰到过类似的问题!直接删除项目中的jar档,然后在eclipse中用加入扩展lib的方式加入Tomcat中的lib,这样编译没有问题,部署也不存在冲突了!

希望能够解决你的问题!

你找到lib文件夹啊,把多余的包删除就可以了撒

应该是你的sturts.xml文件没有找到,你把stuts.xml放到src的目录里(默认)就可以找到

按照下面的,在web.xml里配置一下就行了。
[code="xml"]

action

org.apache.struts.action.ActionServlet


config

/WEB-INF/classes/struts-default.xml //struts-default.xml文件的路径

[/code]

是jar包冲突了
看看有没有重复的jar包
