Thread Handling

Hello, I am new to this discussion group. I found that there are many good discussion about SCJD exam. It helps me a lot in term of doing the design.
However, I did not see any discussion about multi-thread handling. How should we handle the multi-threading for the exam ? Should we create a thread pool in server side ? Where can I find the best reference about creating thread pool ? I found several books talk about it, all of them looks very complicated.

If you choose RMI for a solution, this is all handled for you. Natively RMI has a thread pool, socket reuse and is multi-threaded. Hope this helps.
If you choose sockets, you will have to right your own.

If you use sockets, remember the "favour clarity over performance" requirement and don't use a thread pool. IMHO you'd simply create threads as required.

I seem to be the only person using serialization here and I agree with Peter - Don't use a thread pool. The simple answer is to have one thread per connected clientas this endures that there are no thread management issues.

I am going to use RMI. I have already written a thread pool by following a book. It is nice to know that RMI has already handle the thread pool for me. I will remove the code that I wrote. (It has already be tested without using RMI). Thanks.

Hi John,
It's important to know that, even using RMI, you can still run into threading issues. A Thread pool make sure that you're not wasting threads, but it doesn't keep two threads from attempting to modify the same resource. That's where your locking code comes in.
