Servlet technology is utilized to make a web application (dwells at server side and creates a dynamic web page).
Servlet technology is strong and adaptable as a result of java language. Before Servlet, CGI (Common Gateway Interface) scripting language was prevalent as a server-side programming language. Be that as it may, there were numerous impediments of this technology. We have discussed these weights underneath.
There are various interfaces and classes in the Servlet API, for instance, Servlet, GenericServlet, HttpServlet, ServletRequest, ServletResponse et cetera.
What is a Servlet?Servlet can be depicted from various perspectives, dependent upon the particular condition.

A web application is an application open from the web. A web application is made out of web parts like Servlet, JSP, Filter and so forth and different segments, for example, HTML. The web segments ordinarily execute in Web Server and react to the HTTP ask.
CGI(Common Gateway Interface)CGI technology empowers the web server to call an outside program and pass HTTP ask for data to the outer program to process the demand. For each demand, it begins another procedure.
Inconveniences of CGIThere are numerous issues in CGI technology:- If various customers builds, it sets aside more opportunity for sending a reaction.
- For each demand, it begins a procedure and a Web server is restricted to begin forms.
- It utilizes platform subordinate language e.g. C, C++, Perl.
There are numerous preferences of servlet over CGI. The web compartment makes strings for taking care of the numerous solicitations to the servlet. Strings have a considerable measure of advantages over the Processes, for example, they share a common continue reading
