Could not find action or result warning in Struts 2

I am new to Struts 2, but so far, I have made decent progress using the API.

However, I am stuck at something which I need to get out from. I am using Struts 2 with Spring integration. I am writing my Action classes with annotations as like many of you, I love annotations.

My requirement is that URLs will be in the following nature:

http://<DOMAIN>/program/program1.jspx
http://<DOMAIN>/program/program2.jspx
http://<DOMAIN>/program/program3.jspx

As you can see there is a certain pattern in the URL with program1, program2, and program3 varying, and the rest are all static. I have very easily handled similar situation with Spring MVC (I don't have the option of using Spring MVC for the current project) like "/program/{program_name}.jspx" in my other project.

But when I use the same in Struts 2 I get the error.

My Action class is as follows:

@Result(name="program", location="program", type="tiles")
public class ProgramAction extends ActionSupport {

   @Action("program/{programName}")
   public String getProgramPage() {
     // few more lines of code  
     return "program";      
  }
}

The error is:

My struts.xml file is as follows:

<struts>
<constant name="struts.convention.default.parent.package" value="default"/>
<constant name="struts.action.extension" value="jspx" />
<constant name="struts.mapper.alwaysSelectFullNamespace" value="false" />
<constant name="struts.enable.DynamicMethodInvocation" value="true" />

<package name="default" extends="struts-default, json-default, rest-default" namespace="/">       
    <result-types>
        <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult"/>
        <result-type name="json" class="org.apache.struts2.json.JSONResult"/>
    </result-types>
</package>
</struts>

You have a slash in your action name. struts by default does not like this to correct that add:

<constant name="struts.enable.SlashesInActionNames" value="true"/>
