What is a Servlet?

Introduction to Servlet

You might have heard about servlets at some point, but the question stands – what is a servlet? It is a question that many ask themselves when using Java and first learning of a Java servlet. You may not know of the benefits it can bring you or you may be wary of it in general.

Servlets are helpful little tools that “speak” to the server for you and give you an answer in return. They are safe, effective ways to communicate with servers and can make your applications better. They are also better on the budget and on time, too.

What is a Servlet?

The servlet itself is a class of Java. A Java servlet is written into the code to communicate with the server itself. When you give it commands or requests, it will communicate with the server and give back a response. These reside on the server and speak with the server directly.

When you have a request for the server, you can use the servlet. It will communicate with the server and respond to you directly. It makes it easier to manage web applications that reside on the server.

A Java servlet will work continuously without requiring a reload and will remain reliable. It has all of the benefits of the Java language, as it is part of the Java language. You get the same quality, mobility, and overall usability that you expect of the language.

Advantages of Servlets

A servlet, in nearly every way, makes managing your web application better. It lowers costs and maintenance while simplifying the entire process. It allows you to communicate with and manage your server without worries of hiccups.

All of this is why servlets are so widely popular and preferred in Java. When you have to speak with a server, this is going to make the entire process less overwhelming for you.

It is even less resource intensive than other options. It requires less memory and space, allowing you to continue working without having something bulky taking up too much room.

Anyone can begin using a servlet. There are already options available to make the entire process simpler for you and to give you full access to the potential benefits. Thanks to the lower cost and maintenance required, as well as the overall simplicity and quality, this is one of the most important tools these days. If you still ask yourself, “What is a servlet?” you might want to look into most web applications that run on Java. Most likely, they use it.
