解决方案：

也是网上下载的SSH例子在MyEclipse10上练习，但总是不能成功运行，看过该例子的帮助文档后知道原因是缺少struts2-spring-plugin-2.0.14
jar包了，把这个jar包找到粘贴到你的项目下WEB-INF中lib文件夹中，重新部署，启动，OK。

1. 自己郁闷的是要不是看作者的帮助文档都不知道是去烧这个文件；

2. 为何会缺少这个包？他是属于Spring还是Struts框架的一部分？怎么没有自动添加进去？是我在添加SSH框架时忘了勾选那个选项的原因吗？

3. SSH三个框架的结合那些包是必不可缺少的？也就是说那些包是用来三者之间通讯的？这个必须搞清楚，要不然后面再用SSH做项目时还会出错的。

4. 以上为自己练习时遇到的问题，下面的例二是网上收集的，希望自己有所帮助。

解决方案
1.是因为Hibernate和struts2引入的包产生冲突啦，去把xerces.jar移除就ok啦。路径所在

D:\ProgramFiles\MyEclipse 7.0M1\eclipse\dropins\myeclipse\eclipse\plugins\com.genuitec.org.hibernate.eclipse_3.2.2.z69100_CR1\myeclipse-data\3.0\lib
2.如果用的是tomcat+hibernate的话就去把tomcat中webapp中的对应的项目删除在重新发布一下就解决啦
这两种方案屡试不爽，哈哈...
