JAX-RS failed to inject @EJB or @Inject

I'm trying to test a minimal JAX-RS + EJB/CDI injection mechanism and currently hitting a road-block due to GlassFish unable to inject for whatever reason.

(Using @Inject will throw NPE because GlassFish cannot inject the POJO).

My beans.xml contains only

<beans />

Here's my web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
     version="3.0">
  <display-name>This is a REST Servlet</display-name>
  <servlet>
    <servlet-name>ServletAdaptor</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>ServletAdaptor</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>
</web-app>

Here's the JAX-RS Resource class:

import java.util.List;

import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Stateless
@Path("/employee")
public class EmployeeResource {

    @EJB
    ApplicationScopedEmployeeServiceImpl employeeService;

    @Path("/all")
    @GET
    @Produces({ MediaType.APPLICATION_XML })
    public List<Employee> index() {
        return this.employeeService.getAllEmployees();
    }

}

Last but not least, the actual EJB:

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import javax.ejb.Stateless;
@Stateless
public class ApplicationScopedEmployeeServiceImpl implements EmployeeService {

    final List<Employee> employees = new ArrayList<Employee>();

    public ApplicationScopedEmployeeServiceImpl() {
        final Employee employee = new Employee();
        employee.setEmployeeId(new Date().getTime());
        employee.setFirstName("FirstName-" + employee.getEmployeeId());
        employee.setMiddleName("MiddleName-" + employee.getEmployeeId());
        employee.setLastName("LastName-" + employee.getEmployeeId());
        employee.setScoped("ApplicationScoped");
        this.employees.add(employee);
    }

    /**
     * {@inheritDoc}
     */
    public List<Employee> getAllEmployees() {
        return this.employees;
    }
}

And this is the exception from GlassFish

Would anyone know if there's a problem with JAX-RS and GF 3.1?

The code works if it is a Servlet though :)

Indeed, Jersey does not handle properly dependency injection. So far it seems to be reported and aimed for future releases. http://java.net/jira/browse/JERSEY-517

Facing same issue I had to implement context lookup to get access to managed resource.

So try something like this in your WS constructor:

employeeService = (ApplicationScopedEmployeeServiceImpl) new
                   InitialContext().lookup("java:global/EJB/EmployeeService");
