JSP Introduction

JSP stands for Java Server Pages is a technology for building web applications that support dynamic content and acts as a Java servlet technology. You can consider it a different option to a servlet, and it has a lot more capabilities than a servlet.

JSP is used explicitly for creating dynamic web applications. Pages created using JSP are simpler to manage as compared to a Servlet. JSP pages are the reciprocal of Servlets as a servlet incorporates HTML code within Java code, whereas JSP includes Java code within HTML with the help of JSP tags. JSP can do all the things that a Servlet can do.

Some Facts About JSP

  • JSP stands for Java Server Pages.
  • JSP is Server-side scripting language: Server-side scripting means that the JSP code is processed on the web server rather than the client machine.
  • JSP page is a file with a .JSP extension that contains could be the combination of HTML Tags and JSP codes.
  • JSP is used to build dynamic web applications.
  • JSP is an improved extended version of Servlet technology.

JSP Has More Advantages than Servlet

JSP is considered to be better than servlet; there are many reasons why JSP is more beneficial than servlet:

  • JSP offers an efficient and more straightforward approach for coding dynamic web pages.
  • JSP doesn't need to have additional files such as java class files, web.xml, etc.
  • Web Container (or application server like tomcat) handled changes when changes are done in the JSP code, and it does not need recompilation.
  • Direct access to JSP pages is possible, and hence web.xml mapping is not necessary as you have to do in servlets.

Advantages of JSP

Here is the list of benefits that JSP provides:

  • JSP codes are easy to write and maintain.
  • Development speed becomes fast, and there is no need for recompilation and redeployment.
  • It has high performance and scalability compared to other dynamic web development tools.
  • JSP is constructed on Java technology, which makes it platform-independent.
