REST API with Struts - rest

Question

I'm trying to add a REST API to an existing struts 2 application.
The idea is to have part of the application using standard struts mapping, and another part using REST.
So I used the struts2-rest-plugin plugin, and added the following configuration:
struts.xml:
<constant name="rest" value="org.apache.struts2.rest.RestActionMapper"/>
<constant name="struts.mapper.class"
value="org.apache.struts2.dispatcher.mapper.PrefixBasedActionMapper"/>
<constant name="struts.mapper.prefixMapping" value="/rest:rest,/:struts"/>
struts.properties:
struts.action.extension=,htm,action,xml,json
TasksController.java:
package xxx.common.webservice.rest;
public class TasksController implements ModelDriven<Task> {
public String update() {
return "UPDATE";
}
// Handles /tasks/{id} GET requests
public String show() {
return "YES";
}
#Override
public Task getModel() {
// TODO Auto-generated method stub
return null;
}
}
With this configuration, the basic struts action work, but I can't get the REST actions to work.
I also tried different struts.xml configurations (including the convention plugin options), but without any success, the mappings are never shown with the config-brower plugin.
Any idea of what I have missed or done wrong?

It finally worked, but it was a while ago and I don't remember exactly what I did, here is my configuration, hope this helps.
struts.xml
<constant name="struts.convention.action.mapAllMatches" value="true"/>
<constant name="struts.convention.package.locators" value="webservice"/>
<constant name="struts.convention.action.suffix" value="Controller"/>
<constant name="struts.convention.default.parent.package" value="rest-default"/>
<constant name="struts.mapper.class" value="org.apache.struts2.dispatcher.mapper.PrefixBasedActionMapper" />
<constant name="struts.mapper.prefixMapping" value="/rest:rest,:struts" />
<package name="home" namespace="/" extends="struts-default">
...
</package>
TaskController.java
package com.test.webservice.rest;
public class TaskController extends RestActionSupport implements
ModelDriven<TaskDTO> {
public final HttpHeaderResult show() {
...
}
...
}
