struts2兼容struts1问题，求大神0

struts2-struts1-plugin
官方文档
http://struts.apache.org/release/2.3.x/docs/struts-1-plugin.html
在struts2环境下配置最简单的struts1 action

In the most simple case, where you have a Struts 1 Action that you want to use in Struts 2, configure a Struts 2 action using the wrapper:

<action name="myAction" class="org.apache.struts2.s1.Struts1Action">
  <param name="className">com.mycompany.myapp.MyAction</param>
  <result>myAction.jsp</result>
</action>

访问的时候报错：

严重: Exception occurred during processing request: null

采纳的答案

看了文档，感觉需要注意的应该有
1 To use existing Struts 1 Actions and ActionForms in a Struts 2 application, create a normal Struts 2 configuration package in struts.xml, but have it extend struts1-default. The struts1-default package contains several interceptors and a default interceptor stack that work the plugin into the Struts 2 request process.
这里说需要继承struts1-default

2 This plugin can be installed by copying the plugin jar into your application's /WEB-INF/lib directory. It will need the Struts 1 jar in order to function correctl
相关的插件jar和strus1相关的jar拷贝到/WEB-INF/lib目录下面
