JSP: What are JSP and its advantages?

Hello Friends, In this blog post(What is JSP and its advantages) we are going to let you know about the JSP(Java server pages). Here we will see how the JSP technologies work, and how the JSP is different from the servlet. We will also explore the advantages of JSP over various server-side programming techniques.

JSP and its advantages

What is a JSP example?

Java server pages are Sun’s solution for developing dynamic websites. Jsp’s allow separating the dynamic content of a web page from its static presentation content.

Programming in servlet is very complex and required additional files, such as web.xml and java class files, to generate the required web pages.

JSP offers an easier approach to building dynamic web pages. JSP documents consist of HTML tags and special tags, known as JSP tags.

HTML tags are used to create static page content and JSP tags are used to add dynamic content to the web pages.

<html>
<head>
<title>First Page</title>
</head>
<body>
<H3>Today is :
<%= new java.util.Date() %>
</H3>
</body>
</html>

JSP pages are compiled into a java servlet by a JSP translator. This Java servlet is then compiled and executed to generate an output for the browser( client).

Java server pages are saved with.JSP extension.

In JSP java codes are written between <% and %> tags. So it takes following form: <%=Some expresion %>. In this example, we have used <%= “new java.util.Date()”%> Which display the current date.

The conceptual difference between the JSP and Servlet?

Coding a JSP seems to be simpler than coding the corresponding servlet. In the JSP, we do not have to write complex java code, and worse still, HTML inside that java code. We can write HTML tags, and wherever needed, write java code in between HTML tags.

In other words, Servlet is HTML inside java and JSP is java inside HTML.

Advantages of JSP over various server-side programming techniques: What are the advantages of JSP over technologies other than servlet?

JSP vs ASP: ASP is similar technology from Microsoft, the advantages of JSP over ASP are given below:

The dynamic part is written in java, not visual basic or another MS-specific language as is the case with ASP, therefore it is more powerful and easier to use.

It is portable to other operating systems and non-Microsoft-based web servers.

JSP vs Pure servlet: JSP is similar the servlet. But is easier to write regular HTML than to have million Println statements that generate the HTML. It also separates the look from the content.

JSP vs SSI(Server-side includes): SSI is a technology for including externally-defined pieces into a static web page. JSP is better since it lets them use servlets instead of a separate program to generate that dynamic part. Besides, SSI is really only intended for simple inclusions, not for real programs that use form data, make database connections, and the like.

JSP is a Javascript: Javascript can generate HTML dynamically on the client, this is a useful capability, but handles only those situations where the dynamic information is based on the client’s environment.

With the exception of cookies, HTTP, and form submission data is not available to javascript. And since it runs on the client, javascript can not access server-side resources like databases, catalogs, pricing information, etc.

JSP vs Static HTML: Regular HTML can not contain dynamic information. JSP is feasible to augment HTML pages that only benefit marginally by the insertion of small amounts of dynamic data.

Quick Q&A:

What are JSP and its advantages?

First, it is more powerful and easier to use as its dynamic part is written in java instead of visual basics and any other MS-specific language.

And the second main advantage is it is platform-independent, it is easily portable to other operating systems and non-Microsoft web servers.

Is JSP front end or backend?

The main use of JSP is to create the front-end-related functionality and is mainly used in GUI creation. Servlet works as backend and manages the HTTP request by capturing and redirecting for further processing on the server.

So servlet can be treated as backend controller In the MVC pattern. If we conclude about both then we can say that servlet is HTML in Java and JSP is JAVA in HTML.

Is JSP still used?

As technologies are updating very fastly with few and more modification and peoples are using new technology and technique in place of older.

But it is not completely true about JSP as most of the companies are still using JSP. But this is also true that most of the peoples look for the JS framework over JSP.

Why do we use JSP?

As we have known that JSP is a web-based technology and is used to create dynamic content or web pages. And this is also platform-independent and easily portable to the other operating system. In this Java code can be inserted in both HTML/XML pages. And before processing the client request JSP is first converted into the servlet by the JSP container.

What is the difference between HTML and JSP?

The basic difference between JSP and HTML is that JSP is used to create dynamic web pages whereas HTML is a standard markup language that is used to build the basic structure of the web page. So basically JSP the HTML code with some java code.
