一开始主要是用struts1写程序，在运行的时候就直接导入的IDE直接生成的struts1的的包
没任何问题，
? 今天突然发现，struts2都出来这么久了 ，还在研究struts1 在out ，就简单的写了个struts2的程序 测试下 结果给我报了一大堆的错误 ，不过还好解决 了
? 现在把错误记录下来 希望能对大家有所帮助：

--上面是报出来的错误代码，其最终的解决方法是：
? 你在网上下struts2的包时，它里面会有很多jar包要自己导进入，但有些一开始没用，我这个原因 就是一开始在运行的时候没有导入commons-fileupload-1.2.1.jar? 这个包? ， 所以导致 报错 ，，你只要把这个包导入到你工程的blib目录下
? 后来在导入这个包之后，重启tomcat? 就没问题了 ?
