Hi, this is my problem: my service has two synchronized methods. One
of them writes events and the other listens. This works well with GWT,
but does not work uploaded in GAE.
..
private UserData user = new UserData("mjs");
..
public void writeEvent(String event) {
synchronized (user) {
user.getEvents().add(value);
user.notifyAll();
}
}
public List<String> readEvent() {
List<String> events;
while (true) {
synchronized (user) {
if (user.getEvents().size() > 0) {
events = user.getEvents();
user.setEvents(new ArrayList<String>());
break;
}
try {
user.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
return events;
}
Error LOG:

I think user.notifyAll () will never "wake up" user.wait (), is that
correct?.
Thank you for your help
