Improve this answer. Just curious is there any advantage with respect to performance in JSP than Servlets? JNL The only difference in performance is when you run a modified JSP for the first time, since it has to be converted. After that, it's a servlet as any other one. So is it not same with the Servlets, it runs through the entire lifecycle only if we change the Servlet code? JNL take a look at jspc sometime MichaelT Thanks Michael, Appreciate it. I will try to get back to this question, need to phrase it appropriately, Thanks — JNL.

Servlets run faster than JSP, on the other hand JSP runs slower than servlet as it takes time to compile the program and convert into servlets. In Servlet, you have to implement both business logic and presentation logic in the single file. It saves time to respond to the first request which increases response time.
It uses standard API that is supported by numerous web servers. Programming languages like platform independence and ease of development. You can access the large set of APIs that are available for the Java platform. The web container makes threads for handling more than one request to the servlet. Easy coordination between two or more servlet to make web applications. Servlet containers support many other features like sessions, resource management, persistence, security, etc.
JSPs and Java servlets share similar characteristics, including the ability to access and respond to request objects. Apache Tomcat 9x is the reference implementation for the Servlet 4. Note that updates between JSP 2. We'll use an example application in Tomcat to get you started with JavaServer Pages.
If you don't already have Tomcat installed, browse over to the Tomcat download page and select the Tomcat installation for your operating system. As of this writing, Tomcat 9 is the current release , compatible with Servlet 4. Either way, start up Tomcat, then go to localhost to see the Tomcat welcome page shown in Figure 2. Next, open the Implicit Objects Execute web application. Figure 3 shows output for this application. Take a minute to study this output.
Implicit objects are built-in objects accessible via a JSP page. As a web page developer, you will use these objects to create access to things like request parameters , which are the data sent over from the browser when issuing an HTTP request.
The param is? This example is a very simple introduction to using JSP tags to access server-side request parameters. Introduction It stands for Java Server Pages. It is a server side technology. It is used for creating web application. It is used to create dynamic web content.
It is an advanced version of Servlet Technology. It is a Web based technology helps us to create dynamic and platform independent web pages. JSP pages are more advantageous than Servlet: Attention reader!
