这些错误很让我摸不着头脑，经多方查阅资料后，在Struts 2.2.x中应该导入如下7个JAR文件

1)   commons-fileupload-1.2.1.jar

2)   commons-io-1.3.2.jar

3)   freemarker-2.3.16.jar

4)   javassist-3.7.ga.jar

5)   ognl-3.0.jar

6)   struts2-core-2.2.1.jar

7)   xwork-core-2.2.1.jar

 

其实，这里还有一个小窍门，我们可以将Struts 2.2.x根目录下的apps文件夹下的struts2-blank-2.2.1.war文件进行解压，然后找到WEB-INF下的lib目录，我们可以发现里面列出了7个JAR文件，刚好这7个就是我们配置Struts 2.2.x需要导入的JARs文件
