可能原因：
1、struts.xml 声明部分与struts2-core-2.xxx.jar中struts-default.xml的文件声明不一致
??? 解决：
?? <!DOCTYPE struts PUBLIC? "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
??? "http://struts.apache.org/dtds/struts-2.1.dtd">
??替换为 struts2-core-2.xxx.jar中struts-default.xml的文件声明
? <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
??? "http://struts.apache.org/dtds/struts-2.0.dtd">
???
2、jar包问题，包括jar包冲突（实际碰到是jar问题）
?
?? 解决过程：用web工程中的jar包替换fkjl工程的所有jar包。
