However, computers don’t understand the language that is spoken by human beings. The commands and requests that take place on a computer and are performed by the computer are made by using several computer languages.

There are several programming as coding languages that are used today to create websites, webpages, applications etc. There are several elements in these languages as well.

They contain software components, codes based on several programming languages etc. Two of these are 1. JSP or Jakarta Server Pages and 2. Servlet.

JSP vs Servlet

The difference between JSP and Servlet is the modification process that takes place in the respective components. The modification process in JSP or Jakarta Server Pages is quite simpler and quicker. You just have to click on the refresh button to do so. On the other hand, the modification process in Servlet is quite a hassle and takes time.

JSP vs Servlet

JSP or the Jakarta Server Pages is code that is based on the programming language of HTML. It is written in java in HTML format. It is easy to code because of the format that is used to create it.

It was developed by the Eclipse Foundation in the year 1999. It is an open format webpage.

Servlet or Jakarta Servlet is a type of code that is written in java language. In the MVC approach, the servlet plays the role of a controller. It is considerably faster than many other codes.

In servlet, all the protocol requests are accepted, and the service method can be overridden.

What is JSP?

JSP or Jakarta Server Pages is a code that is based on the HTML programming language. The compiler that is used for Jakarta server pages is the JavaServer pages compiler. It is a type of program that changes the code into an executable one.

In order to run the Jakarta server pages, one must require a web server that is compatible enough.

The dynamic web late format is used in the Jakarta server pages. It was developed in the year 1999 by the Eclipse Foundation. In the MVC approach, Jakarta server pages play the role of the view for displaying the output.

There are two steps that are involved in the lifecycle of the Jakarta server pages.

These two steps include translation and compilation. In the first step, the Jakarta server pages are translated into the java code and then it is further compiled.

The Jakarta server pages only accept the requests by HTTP protocols, and the method service can not be overridden in it.

There are many features and advantages that are provided by the Jakarta server pages. The Jakarta server pages can be used as HTML pages, and dynamic content like dropdown and checkboxes can be added to them.

There are several response objects as well as request objects that can be used to share data.

What is Servlet?

Servlet or Jakarta Servlet is a type of software component. The original author of the Jakarta servlet is Pavni Diwanji. The developer of the Jakarta servlet is the Eclipse Foundation. It was founded in the year 1996.

It is a type of software component that is written in the Java language.

The inception of the Java servlet took place during the inaugural conference in the year 1996. Various transactions take place over the entire server. During these transactions, the work of maintaining the state of the session is important.

A servlet does the job of maintaining the sessions. They make use of HTTP cookies to do so.

There exists an element in the web servers that holds several interactions with various servlets. That element is known as the web container or a servlet container.

It is an integral part of a servlet and a server in general because it plays an important role in the management of the entire lifecycle of the servlet. Therefore, it must be used while deploying a servlet.

The Jakarta servlet is one of the portable options that one can choose because it is written in the java language. It is also secure enough and robust, so one must not worry about any leak in the memory or accumulation of garbage in the system.

A thread instead of a process is created for each request which results in better performance.

Main Differences Between JSP and Servlet

  1. The JSP is also known as the Jakarta server pages. On the other hand, the server is also known as the Jakarta servlets.
  2. Only HTTP requests are accepted by the Jakarta server pages. On the other hand, requests by all the protocols are accepted by the Jakarta servlet.
  3. The modification process in the Jakarta server pages is faster than the modification process in the Jakarta servlets because the modification process in the Jakarta servlets includes three stages.
  4. The Jakarta server pages are slow. On the other hand, the Jakarta servlets are fast.
  5. Coding is easier in the Jakarta server pages. On the other hand, coding is difficult in the Jakarta servlets
  6. In the Jakarta server pages, the code used is java in HTML. On the other hand, in the Jakarta servlets, the code used is HTML in java.
