A Jakarta Servlet formerly Java Servlet is a Java software component that extends the capabilities of a server. Although servlets can respond to many types of requests, they most commonly implement web containers for hosting web applications on web servers and thus qualify as a server-side servlet web API. Servlets could in principle communicate over any client—server protocol, but they are most often used with HTTP.

However, CGI is not an efficient solution. For every request that comes in, the web server has to create a new operating system process, load an interpreter and a script, execute the script, and then tear it all down again. While these solutions offer better performance and scalability, all of these technologies suffer from a common problem: they generate web pages by embedding HTML directly in programming language code. This pushes the creation of dynamic web pages exclusively into the realm of programmers. JavaServer Pages, however, changes all that. JSP tackles the problem from the other direction.

It allows a web client to pass data to the application running on the web server so that a dynamic web page can be returned to the client according to the input data. For example, when you use a search engine, buy a book at an online store; get a stock quote etc. CGI is not a programming language, rather it is an interface or a set of rules that allows an input from a web browser and produce an output in the form of HTML page. Out of these, Perl is most commonly used. When a web server receives a request for a CGI script, the web server passes some parameters to this script and executes it. The script runs and generates some output which is then collected by the web server and returned to the client browser. CGI is a true cross-platform technology.

CGI technology enables the web server to call an external program and pass HTTP request information to the external program to process the request.
