ABOUT KAN SOFTWARE• KAN Software is a software development and IT

outsourcing company in Udaipur started in 1999. KAN Software, mainly a software consulting firm provides ERPs and business solutions to various sectors across the globe.

INTRODUCTION TO SEVLETS•A java servlet is a java class extending HTTPServlet

class•A java servlet class implements the doGet(), doPost()

or other equivalent HTTP method and (usually) prints at the standard output an html file

•A java servlet class can contain any kind of java code the JDK can compile

Servlet Life Cycle

The web container maintains the life cycle

of a servlet instance

•Servlet class is loaded.•Servlet instance is created.•Init method is invoked.•Service method is invoked.•Destroy method is invoked.

The classloader is responsible to load the servlet class.

The servlet class is loaded when the first request for the servlet is received by the web container.

The web container creates the instance of a servlet after loading the servlet class.

The servlet instance is created only once in the servlet life cycle.

The web container calls the init method only once after creating the servlet instance.

The init method is used to initialize the servlet. It is the life cycle method of the javax.servlet.Servlet interface.

Syntax of the init method is given below:

public void init(ServletConfig config) throws ServletException  

The web container calls the service method each time when request for the servlet is received.

If servlet is not initialized, it follows the first three steps as described above then calls the service method.

If servlet is initialized, it calls the service method.

Notice that servlet is initialized only once.

The syntax of the service method of the Servlet interface is given below:

public void service(ServletRequest request, ServletResponse response)  throws ServletException,  IOException 

The web container calls the destroy method before removing the servlet instance from the service.

It gives the servlet an opportunity to clean up any resource for example memory, thread etc.

The syntax of the destroy method of the Servlet interface is given below:

public void destroy()  

JAVA SERVER PAGES(JSP)• JSP technology is used to create web application just

like Servlet technology. It can be thought of as an extension to the servlet because it provides more functionality than servlet.

•A JSP page contains HTML code and JSP tags. The jsp pages are easier to maintain than servlet because we can separate designing and development. It provides some additional features such as Expression Language, Custom Tag etc.

JSP Scripting Element

• The scripting elements provides the ability to insert java

code inside the jsp. There are three types of scripting

elements:

• Scripting elements:

1. scriptlet tag

2. expression tag

3. declaration tag

Advantage of JSP over Servlet

• JSP is the extension to the servlet technology. We can use all the features of Servlet in JSP.

• In addition to, we can use implicit objects, predefined tags, expression language and Custom tags in JSP, that makes JSP development easy.

• JSP can be easily managed because we can easily separate our business logic with presentation logic. In servlet, we mix our business logic with the presentation logic.

• If JSP page is modified, we don't need to redeploy the project. The servlet code needs to be updated and recompiled if we have to change the look and feel of the application.

PROJECT BRIEFThe goals of our system are: •To provide a anytime anyplace service for the

customer•To minimize the number of staff at the ticket box •To promote the film on the internet•To increase the profit
