查看struts.xml文件的DOCTYPE定義如下：

1 <!DOCTYPE struts PUBLIC 2 "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" 3 "http://struts.apache.org/dtds/struts-2.1.dtd">

再查看xwork的jar包是2.0的，所以將DOCTYPE的定義也改成2.0的即可

1 <!DOCTYPE struts PUBLIC 2 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 3 "http://struts.apache.org/dtds/struts-2.0.dtd">
