I am trying to implement the SEO friendly URL something like /movies/{id}/actors/{actor_id} to point out to the actor details of a particular movie. So I tried using the Advanced Wildcard mappings, but it isn't working when I have the REST API implemention in my project, but the same is working in a project where I have a simple struts2 application, which shows the JSP pages as results.
Here are the files of the simple struts2 application that works:
struts.xml

Can someone please help me to figure out what should be done to make it working? I also tried adding <constant name="struts.mapper.class" value="org.apache.struts2.dispatcher.mapper.Restful2ActionMapper" /> from Restful2ActionMapper.
