I was thinking about ThreadLocal as it is very popular in Java EE but one request might be handled by multiple threads from IO thread to worker thread which means you have to instantiate as many objects as the number of total threads. Just trying to find if there are any better solutions. Thanks for your confirmation.

If you want one per thread just use ThreadLocal.

I need to share the same instance of a "Util" object to reuse it in all the handleRequest calls. Where is the best place to store the Util object instance? The Util class is not thread safe, so I should have one instance for each client thread.

Thanks,

Steve
