Hi

Let say there are multiple servlet request from the user and each of the request will result int calling the same EJB method available at the back-end project (back-end and front-end project are 2 separated projects), will the back-end spawn additional threads to handle the request? The reason of being asking this question is that I got a strange occurrence while building a ejb timer service back-end. Initially, when my front-end is deployed onto a AS, it will automatically start a servlet and resulting in creating a timer with ejb timer service at the back-end. Everything looks good. I have other ejb functions that will check the next timeout time and info of the timer and such information will be displayed onto a jsp using ajax.

I got everything working and I can see that there is only 1 timer event running at the back-end from the console. But if I keep refreshing the page and retrieve the next timeout time and info of the timer from jsp, I can see that the back-end suddenly have another timer started and I can see that the timer is running at the initial configuration of my back-end (i have a counter to keep track of how many times does the timer has timeout, in this case, the counter shows 1 for the new timer and x for the old existing timer). I am pretty sure that I did not have any create timer business logic during anywhere on my front-end and back-end except at the start up servlet. If I cancel the timer, both timer will be canceled.

So. It is the multiple ajax request from the jsp resulting in creating another instance or thread of the timer object?
