JSP Tutorials and examples, you will find many examples with working source code.

  1. Introduction to JSP
    Java Server Pages or JSP for short is Sun's solution for developing dynamic web sites. JSP provide excellent server side scripting support for creating database driven web applications.
     
  2. JSP Tutorials - Introducing Java Server Pages Technology
    JavaServer Pages (JSP) technology is the Java platform technology for delivering dynamic content to web clients in a portable, secure and well-defined way.
      
  3. JSP Architecture
    JPS pages are high level extension of servlet and it enable the developers to embed java code in html pages. JSP files are finally compiled into a servlet by the JSP engine. Compiled servlet is used by the engine to serve the requests.
     
  4. Introduction to the JSP tags(This section also describe JSP Directives)
    In this lesson we will learn about the various tags available in JSP with suitable examples. In JSP tags can be devided into 4 different types.
      
  5. Detail introduction to JSP Declaratives
    JSP Declaratives begins with <%! and ends %> with .We can embed any amount of java code in the JSP Declaratives. Variables and functions defined in the declaratives are class level and can be used anywhere in the JSP page.
      
  6. Detail Introduction to JSP Scriptlets and JSP Expressions with examples
    JSP Scriptlets begins with <% and ends %> .We can embed any amount of java code in the JSP Scriptlets. JSP Engine places these code in the _jspService() method.
     
  7. Writing the Date JSP
    Till now you learned about the JSP syntax, now I will show you how to create a simple dynamic JSP page that prints the current date and time.
      
  8. Reading the Request Information
    When an HTTP client such as web browser sends a request to a wen server, along with the request it also sends some HTTP variables like Remote address, Remote host, Content type etc.
     
  9. Retrieving the data posted to a JSP file from HTML file
    Now I will show you how to retrieve the data posted from a HTML file in a JSP page. Consider an html page that prompts the user to enter his/her name, let's call it getname.htm.
      
  10. Accessing database fro JSP
    In This article I am going to mdiscuss the connectivity from MYSQL database with JSP.we take a example of Books database. This database contains a table named books_details.
     
  11. Working with JSP Sessions
    This JSP Tutorial shows you how to track the session between different JSP pages. In any web application user moves from one page to another and it becomes necessary to track the user data and objects throughout the application. JSP provide an implicit object "session", which can be use to save the data specific the particular to the user.
      
  12. JSP Cookies Example
    This tutorial shows how to handle cookies in JSP pages. In this tutorial you will learn how to add cookies through jsp page and then show the value of the same cookie in another JSP page.

JSP Fundamentals
This is an excellent tutorial on JSP for the beginners. Tutorial describes how to use Bean in JSP, Connection Pooling in JSP and the use of taglibs. 

    • JSP Fundamentals
      JSP termed as Java Server Pages is a technology introduced by Sun Microsystems Inc. to develop the web application in more efficient way than Servlets. It has got many advanced features than servlets, one of them itself define the JSP i.e. JSP separates the presentation logic from the business logic and provide the designer and developer of the web application to work independently without any hassle.
       
    • Using Beans in JSP
      Java Beans are reusable components. They are used to separate Business logic from the Presentation logic. Internally, a bean is just an instance of a class.
         
    • JSP Taglibraries
      JSP?s offer a unique feature of ?Tag Libraries?. Simply put, these are custom defined JSP tags. They are basically meant for componentizing presentation level logic. They are very similar to beans except the fact that Beans are used to separate Business logic.

 

JSP Examples

  1. Calculate a factorial by using while loop
    In this example we are going to find out the factorial of 12 by using the while loop. In while loop the loop will run until the condition we have given gets true.
     
  2. Calculate factorial
    After going through this example you will be understand how you can calculate the factorial by using recursion in jsp. To make a program on factorial, firstly it must be clear what is recursion.
      
  3. Celsius to Fahrenheit
    Celsius is a unit to measure temperature scale on which water freezes at 0 degree and boiling point is 100 degree. This unit is discovered by Celsius in 1742, a Swedish astronomer and physicist, he has invented the centigrade, or Celsius thermometer divided between the freezing and boiling points of water into 100 parts.
      
  4. Comment
    In a jsp we should always try to use jsp- style comments unless you want the comments to appear in the HTML. Jsp comments are converted by the jsp engine into java comments in the source code of the servlet that implements the Jsp page.
      
  5. Html tag inside out implicit object
    In this program we are going to use a html tag inside a out object. out object is used to display the content on the browser. To make this program run use out object inside which define some html code along with the content you want to display on the browser
      
  6. Jsp methods
    In this example  we are going to show you how we can declare a method and how we can used it. In this example we are making a method named as addNum(int i, int b) which will take two numbers as its parameters and return integer value.
      
  7. multiple method
    Jsp is used mainly for presentation logic. In the jsp we can declare methods just like as we declare methods in java classes. Methods can be declared in either declaration directive or we can declare it in scriptlet. If we declare method inside declaration directive, then the method is applicable in the whole page.
     
  8. Passing Array method
    Array is a collection of similar data type. It is one of  the simplest data structures. Arrays holds equally sized data elements generally of the similar data type.
      
  9. Two index 
    In this example we will show how we can use two indexes in a for loop. We can solve this problem by using for loop defined inside the scriptlet directive.
           
  10. Celsius To Fahrenheit
    In this example you will learn how to convert the temperature Celsius to Fahrenheit. To change the Celsius to Fahrenheit we have the formula Fahrenheit = 32 + 9*c/5.
      
  11. JSP Methods
    In this example we are going to show you how we can declare a method and how we can used it. In this example we are making a method named as addNum(int i, int b) which will take two numbers as its parameters and return integer value.
     
  12. Multiple Methods
    Jsp is used mainly for presentation logic. In the jsp we can declare methods just like as we declare methods in java classes. Methods can be declared in either declaration directive or we can declare it in scriptlet.
      
  13. Hello World JSP Page
         By this example we are going to teach you that how can you write a "hello world" on your browser. Jsp can be learned very easily. This is just the beginning to learn this exciting language.
