一开始，从struts2.2.1导入了5个包：
commons-logging-1.0.4.jar
freemarker-2.3.16.jar
ognl-3.0.jar
struts2-core-2.2.1.jar
xwork-core-2.2.1.jar
结果启动tomcat的时候，报错了：

在网上查找，说2.1.6开始就要再引入两个包：
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
然后引入这两个包，重启tomcat。还是有问题：

然后找到了下面这个帖子：
http://topic.csdn.net/u/20100825/22/bc4344a1-9cd9-45a1-a12d-012a9a3e99b5.html
其中有人回帖：
在使用struts-2.2.1时，需要引入javassist-3.7.ga.jar，而这个在struts-2.2.1\lib下是没有的，需要在struts-2.2.1\apps\struts2-blank-2.2.1.war下的lib中找。
然后引入，重启Tomcat，搞定！
另外的一个回帖说：
把ognl-3.0.jar换成ognl-2.6.11.jar
这个方式也可以。
看来使用ognl-3.0.jar还得再搭配javassist-3.7.ga.jar
