404 Error while deploying simple web-app in JBoss AS 6 and JBoss AS 7? - rest

Question

I followed this blog for injecting EJB in REST layer.
Here is the code that I tried deploying in JBOSS AS 6 and 7 using Eclipse:
REST:
package com.example.rest;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
#Stateless
#Path("current")
public class ServiceFacade {
#EJB
ServiceImpl service;
#GET
public String getDate(){
return service.getCurrentDate().toString();
}
}
EJB:
import java.util.Date;
import javax.ejb.Stateless;
#Stateless
public class ServiceImpl {
public Date getCurrentDate(){
return new Date();
}
}
#ApplicationPath("rest")
public class RestApplication extends Application {
}

Here is the log from deployment to JBOSS AS 6:

Answer 1

I am checking one of my projects using rest and in the annotation I use a slash / before the resource name both in #ApplicationPath("/rest") as in the rest service `#Path("/current"), so your EJB seems like must be something like:
#Stateless
#Path("/current")
public class ServiceImpl {
#GET
public Date getCurrentDate(){
return new Date();
}
}
And your activator class something like:
#ApplicationPath("/rest")
public class RestApplication extends Application {
}
