Jboss error: The ResourceConfig instance does not

Question

I know this is a general question and it is already answered but those answers are not helping for this case.

I am getting this error in only Jboss7.1 final release not in Tomcat(working fine with tomcat version 7) (checked with the same WAR file)

com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.
com.sun.jersey.server.impl.application.RootResourceUriRules.<init>(RootResourceUriRules.java:99)
com.sun.jersey.server.impl.application.WebApplicationImpl._initiate(WebApplicationImpl.java:1300)
com.sun.jersey.server.impl.application.WebApplicationImpl.access$700(WebApplicationImpl.java:163)

REST Resource class

@Path("/hello")
public class HelloWorldService {

    @GET
    @Path("/{param}")
    public Response getMsg(@PathParam("param") String msg) { 
        String output = "Jersey say : " + msg; 
        return Response.status(200).entity(output).build(); 
    }

}

Note:
I have removed the Restlet from Jboss.as standalone config otherwise it gives different error.
