解决：

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.

具体原因是不是以上所说不清楚，不过删除后确实好了，死马当活马医了。。。

解决办法：

将xerces-2.6.2.jar文件删除(版本不一定相同)或者在lib目录中删除，然后把服务器部署过的此项目也删掉，重新部署一下，应该没问题了。

一般出在ssh整合过程中，属于不兼容问题
