How to handle timeout of AsynchronousResponse object in RestEasy - http

Question

i am implementing a jax-rs service with RestEasy on JBoss AS 7.1.2 an i would like to use asynchronous HTTP processsing as described here: http://docs.jboss.org/resteasy/docs/1.0.0.GA/userguide/html/Asynchronous_HTTP_Request_Processing.html
For thr AsynchronousResponse I define a timeout of 10 seconds. When this period expires, the request is responded with a 200 OK and an empty body. I would like to modify this behaviour so i need to be notified about the timeout event.
In my solution, I would like to handle the timeout event in a NotificationManager object, which keeps the AsycnhronousResponse for the time being. Please see the code below for details.
So far, i could not figure out how to do that. Does anyone have more experience with the RestEasy Asynchronous HTTP processing?
#POST
#Path("/blabla")
#Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
#Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public void subscribeLongPolling (
final #Suspend(10000) AsynchronousResponse response,
JAXBElement<LongPollingRequestParameters> rqParam,
#Context HttpServletRequest req) throws Exception {
//do some stuff with req
Thread t = new Thread("ThreadSubscribeTo:" + channelID)
{
#Override
public void run() {
//hand over to Notification Manager to return notifications in case some exist
try {
NotificationManager nm = new NotificationManager();
nm.setAsyncResponseObject(response);
logger.info("Response object registered in NotificationManager");
}catch (Exception e){
e.printStackTrace();
}
}
};
t.start();
logger.info("Releasing Thread");
}
public class NotificationManager {
private AsynchronousResponse response;
private NotificationList nList;
public synchronized void setAsyncResponseObject(AsynchronousResponse response) {
this.response = response;
if (nList.getAny().size() > 0) {
logger.info("Stored notification send to web client: " + nList.getAny().get(0).toString());
sendNotification(nList.getAny().remove(0));
}
}
public synchronized void sendNotification(Object message){
if (response != null){
logger.info("Response object found. Send notification immediately: " + message.toString());
Response responseObject = Response.ok(message, MediaType.APPLICATION_XML).build();
response.setResponse(responseObject);
response = null;
}else{
logger.info("Response object not found notification will be stored");
addNotification(message);
}
}
}
Thanks in advance,
Alex
