Here are some simple steps that can help you solve the problem with the Java Servlet Thread Model. The stream-per-request model has been implemented since the introduction of synchronous servlet coding. This model was adopted by servlet containers for handling incoming requests. Because request tracking is synchronous, this model requires a lot of messages to process requests. Hence, it increases the use of the link.

If it is obvious that requests are being processed sequentially by servlets, web programs will run very slowly. Servlets generally need to be thread safe, since a single servlet-bound instance can be responsible for handling multiple requests at the same time.
As a rule, the web application container constantly maintains a pool of threads for processing questions, etc.and this incoming requests are assigned to publications as needed.

Thanks for the next answer! But for clarity, I will show something else. Thread safety means that no internal state is used in the servlet. This ensures that each servlet instance in the pool exists and has the same locale as it was created. How reliable am I? Many thanks! – Dunit Dhanushka January 19, 2010 5:30 PM

A class without cooling or freezing is thread safe, but it is not the only way to ensure thread safety. Thread safety itself is a long discussion, but for example a class with internally. a problem can be thread safe if it serializes usage internally. â € “next January 19, 2010 at 05:31 PM

Servlets also remain thread safe because they store state information in other servlets (objects of this form, stored in ServletContext and HttpSession). – Paul Rayner January 19, 2010 5:54 PM

So you primarily mean to bind your access request to a servlet instance? – JaskeyLam Jul 18 ’14 at 10:36
Thanks in advance for your reply! But I still need to clarify something. Thread safety means that no internal state is maintained in the servlet. Almost all servlet instances are pooled and in the same state in which they were created. I’m right? Many thanks! – Dunit Dhanushka January 19, 2010 5:30 PM
A class without an internal ground is thread safe, but this is not the only way to be thread safe.dangerous. Thread safety itself is a lengthy discussion, but for example an internal state class can potentially be thread safe if it serializes access to its internal state. â € “next January 19, 2010 at 05:31 PM
Servlets must also be thread-compatible as they share state information with multiple servlets (objects that are only stored in ServletContext and HttpSession). – Paul Rayner January 19, 2010 5:54 PM
So you mean a place for your request to access a single instance of a servlet? – JaskeyLam Jul 18 ’14 at 10:36
In the past, depending on your servlet, you had two models. When the implemented SingleThreadModel servlet is used, applications are queued. Otherwise, this is the only model currently, the servlet obviously needs to be able to serve multiple requests at the same time. So there are no queues in this model, euwhether only the container is not equipped with a speed limit function.

Yes, there is a single threaded interface model. This is the pistol interface.it synchronizes this servlet object, that is, only one function at a time as a thread object. But such considerations lead to a delay in response. The solution is to create object-oriented pools, but this pool is small. Therefore, it is preferable to use a synchronized block
