title: How to enable struts2 convention plugin
body: <p>The problem seems silly because I properly misunderstood the document. Basically I just want to run the hello-world actionless example according to this <a href="http://struts.apache.org/2.1.6/docs/convention-plugin.html" rel="nofollow">instruction</a> by simply adding hello.jsp file into <strong><em>WEB-INF/content</em></strong> and then running <strong><em>localhost:8080/test/hello</em></strong>, but Struts keeps showing the exception <strong><em>java.lang.NoSuchMethodException: com.opensymphony.xwork2.ActionSupport.index()</em></strong>.</p>
  
  <p>So I wonder there is any configuration need to be done before running. I couldn't find any thing about configuration for hello-world example.</p>
  
  <p>Could anyone suggest me correct way ? Thanks</p>
