Servlet waiting for threads to end

Question

Hi !
To make our web app more efficient, we wanted to delegate some work to threads. But it seems that the servlet engine (or something else) is waiting for all spawned threads to end before sending the response back to the browser. So, if a servlet finishes execution but the threads it spawned are still working, I do not get the next page in the browser. I only do when all threads are done. So my question is : is this a normal behavior of the servlet engine ? If so, why ? If not, what could I have done wrong, what should I look out for when using threads inside servlets ?
Thanks,
Martin

Yup I agree with the other guys.
I am building a servlet that has 2 threads running continuously (looping), and they do not bother the requests/responses at all. But in your case if I understand correctly, you spawn threads from the request. You must have some kind of interaction between them.
Are you sure you are spawning the code in a separate thread??. I use something like this:
class Mythread extends Thread
public void run()
// code here
THread threadobject = new Mythread();
threadobject.start(); //( DO NOT CALL THE run() method, but the start() method.)
Are your threads sleeping (to not hog up all CPU power???). Are your threads higher priority then the normal?.
See ya,
