2. WHAT IS JSP?
• JSP is a server-side programming technology.
• It was developed by Sun Microsystems in 1999.
• It’s the fast way to create web pages to display dynamic
data.
• JSP page contains both dynamic and static data.

3. • We can easily create web applications even with less
knowledge in java.
• The extension of JSP page is .jsp or .jspx.
• It was initially developed to replace servlet but now we use
it together using MVC(model-view-controller) pattern.
• A JSP page after compilation generates a servlet and
therefore incorporates all servlet functionalities.

4. What is servlet?
• Servlet is a server-side program and it is executed in a web
server.
• It receives HTTP requests from users and returns HTTP
responses.
• It is written in java and runs on every platform that
supports java.
• And it is currently supported by most of the popular web
servers.

5. Servlet and JSP thus share common features such as
I. Platform independence.
II. Creation of database-driven web applications.
III. Server-side programming capabilities.
However , there are some basic differences between servlets
and JSP and they are:

6. JSP VS Servlet
SERVLET:
 Servlets tie up files i.e., a HTML file for static contents and a
java file for dynamic contents to handle both independently.
 Due to this , a change made to any file requires recompilation
of the servlet.

7. JAVA SERVER PAGE:
 JSP allows java to be embedded directly into an HTML page
by using tags.
 The HTML content and the Java content can also be placed
in separate files.
 If any changes is made into the HTML content , it will be
automatically compiled and loaded onto the server.
