I am exposing a singleton EJB as restful service; requirement is to initiate a timer via Rest API. As this is going to be web app, i am packing ejb class in war file. I am successfully able to deploy the bean and invoke the web service, but could not initiate the timer as @Resource annotation is not injecting SessionContext in the aforementioned singleton ejb (tried with stateless session bean as well). When debugged I see SessionContext object is null. Any suggestions on how I can make the timer service work in this scenario? Below are details:
- JBoss 7.1.1 Final
- RestEasy 2.3.7 Final
- Java 7
TimerSessionBean.java:
import javax.annotation.Resource;
import javax.ejb.SessionContext;
import javax.ejb.Singleton;
import javax.ejb.Timer;
import javax.ejb.Timeout;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
@Singleton
@Path("/config")
public class TimerSessionBean {
@Resource
private SessionContext context;
@GET
@Path("{id}")
public void createTimer(@PathParam("id") long duration) {
context.getTimerService().createTimer(duration, "Hello World!");
}
@Timeout
public void timeOutHandler(Timer timer) {
System.out.println("timeoutHandler : " + timer.getInfo());
}
}
