I did try an example and below are the codes


package com.sample.rest.service;
 
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;
import com.test.ejb.PrimaryStatelessBean;
import com.test.ejb.SampleSingletonBean;
 
@Stateless
@Path("/services")
public class PrimaryStatelessBean{
 
     @EJB
    PrimaryStatelessBean primaryStatelessBean;
    
    @EJB
    SampleSingletonBean sampleSingletonBean;
 
    @GET
    @Path("/getValue")
    @Produces("text/xml")
    public String getValue(){
        
        //To get initial value
        System.out.println("Before Setting Value::" + 
primaryStatelessBean.getMessage());
 
        //set value for the Bean
        primaryStatelessBean.setMessage("Hi Buddy Cool!!");
        
        //After setting value
        System.out.println("After Setting Value::" + 
primaryStatelessBean.getMessage());
        
        return 
"<MESSAGE>"+primaryStatelessBean.getMessage()+"</MESSAGE><REQUEST_COUNT>"+ 
sampleSingletonBean.getCount()  +"</REQUEST_COUNT>";
 
    }
