Introduction to Servlets in Java | Servlet & JSP #1

What is Java Servlets?
Servlet is basically a java file which can take the request from the client and process the request and provide response in the form of html page.
Deployment descriptor mentions which servlet should be called for which request and mapping can be done using xml files or annotations

Today we all are aware of the need of creating dynamic web pages i.e the ones which have the capability to change the site contents according to the time or are able to generate the contents according to the request received by the client. If you like coding in Java, then you will be happy to know that using Java there also exists a way to generate dynamic web pages and that way is Java Servlet. But before we move forward with our topic let’s first understand the need for server-side extensions.
Servlets are the Java programs that runs on the Java-enabled web server or application server. They are used to handle the request obtained from the web server, process the request, produce the response, then send response back to the web server.
