Today websites are the most happening things in the world for all of our uses. To just display the information of your company, a static website is enough and can be built using just HTML, and if you want to beautify it, you can use Bootstrap, CSS, etc. But if you want to make your site interactive, responsive to the client’s requests then you need to use some programming concept in this. Adding to programming to the web designing is done using a programming language called JSP which is Java Server Pages, whose roots are extracted from the Java. For some scenarios such as to directly insert the list from the database to the dropdown in the front end, etc. can be done by the JSP. The main motto of it is to add dynamism to the website by using simple lines of code. Simply, inserting of the programming code for conditions and verifications in the website is done through JSP. You can add no of line of code into the existing Java code by just using some tags called scriptlet tags, which looks something like this “<%… %>”. As sometimes it is also necessary to add dynamism through Java in the code, we use JSP.
Programming is nothing but making computer do whatever you want. It is very simple to learn JSP if you have the knowledge of the Java. Almost all of its syntax, functions are extracted from the Java library, you just need to know where and how to use the conditions in web developing.
Based on the XML, HTML and other languages, JSP is used to create dynamic web pages in a simpler way and which makes the developers life easier. Sun Microsystems has released it in the year 1999. Its services are very similar to ASP and PHP but the difference is that it is purely Java based and is written in Java programming language.
It is used to create web applications and enterprise applications for the huge organisations, and businesses, it is a server-side programming language that is used to create web applications which are dynamic, secure, platform-independent, transactional, etc. It includes all the libraries, APIs such as Java and JDBC APIs to access the databases in it.
How to implement JSP?
To fulfill a role for a Java web application of a user interface, a type of java Servlet component called Java Server Pages is introduced. JSP code can be inserted into the XHTML, HTML code or can be written in other files with the .jsp extension and can be called in the other files. The files are embedded with the commands and actions of the JSP.
There are different types of JSP tags such as Declarative, Expression, Action, Scriptlet, etc tags for different purposes such as to register user preferences, accessing the components of Javabeans, retrieving the data from the database, sharing of data between the pages, components, passing of controls between pages, etc.
