Is Java Servlet single threaded or multithreaded?
Servlets are multithreaded – this is the base for their efficiency. One can use “implements SingleThreadModel” to make a servlet single-threaded, so for every request a new object will be created.
Are servlets threads?
By default, servlets are not thread-safe. The methods in a single servlet instance are usually executed numerous times simultaneously up to the available memory limit. Each execution occurs in a different thread, though only one servlet copy exists in the servlet engine.
What is the difference between generic servlet and HTTP servlet?

What is threading issues in servlet?
6.5. Most servlet threading problems occur when two or more threads make changes to the same resource. This might mean that two threads try to modify a file, or perhaps several threads all update the value of a shared variable at the same instant. This causes unpredictable behavior and can be very hard to diagnose.
What is servlet container thread?
A Java servlet container / web server is typically multithreaded. That means, that multiple requests to the same servlet may be executed at the same time. Therefore, you need to take concurrency into consideration when you implement your servlet.
Are servlets platform independent?
Servlets are platform-independent because they are written in Java. Java security manager on the server enforces a set of restrictions to protect the resources on a server machine.
What is the difference between doGet () and doPost ()?
doGet() shall be used when small amount of data and insensitive data like a query has to be sent as a request. doPost() shall be used when comparatively large amount of sensitive data has to be sent. Examples are sending data after filling up a form or sending login id and password.
Do you prefer to implement multithreading in a servlet?
Thanks for your reply.So it means we will be getting better performance if we are implementing multithreading in a servlet.But,people never prefer to implement multithreading in a servlet.Can you tell me why it is so??
How does servlet work in container?
When first web request comes in, the container will load the Servlet class, calls its init method, then calls its service method to process the web request. It says there can be only one instance of servlet class.

Java Servlet life cycle is managed by the servlet container. When first web request comes in, the container will load the Servlet class, calls its init method, then calls its service method to process the web request. It says there can be only one instance of servlet class.
What is multithreading and why is it important?
I don’t know where you got this idea. Multithreading is essential for web sites where performance is a factor (which means just about all of them).
