Model Elements & Responsibilities

View Elements & Responsibilities

Challenges Exist In Software

Development & Software Crisis

Project must be developed Quickly.

Project must be in High-Quality.

Easy to maintain.

Easy to test.

Better separation of concerns.

What is Framework & It’s Advantages

Framework:-

A software framework is a re-usable design for a software system (or subsystem).

A framework is pre-built assembly of components and we can extend it.

Advantages:-

Provides a procedure for the development of Application.

Save developers time.

It also reduces software development & maintenance costs.

Provides low level services that developers can use to speedup developments.

Provides same approach for all developers for developing code & Consistency in software design.

Model1 & Model2

Model1:-

In the Model 1 the JSP page is responsible for processing

the incoming request & replying back to the client.

Disadvantages of Model 1 Architecture

It does not have separate controller.

This Architecture usually leads to a significant amount of

java code embedded within the JSP page.

Time consuming.

Hard to extend:- It is better for small application not for

large application.

Navigation control is Decentralized :- Every page contains

the logic to determine the next page.

Model 2 Architecture

Model2 is based on the MVC(Model View Controller) design pattern.

Model:- Represents data & Business logic of the Application.

View:- Responsible to Display Data. It represent the presentation.

Controller:- Acts as an Interface between View & Model.

Model 2 Architecture Advantages &

Disadvantages

Navigation control is Centralized:- Now only controller contains the

logic to determine the next page.

Easy to maintain.

Easy to extend.

Easy to Test.

Better Separation of concerns.

Disadvantages:-

We need to write the controller code self. If we change the controller

code, we need to recompile the class file.

What is Struts ? & its Features

An Open source web Application framework based on J2EE & java

which implements the MVC design pattern is called Struts.

Features:-

Configurable MVC components.

POJO based action.

AJAX support.

Integration support.

Various Result types.

Various Tag support.

Theme & Template support.

Struts Framework Components

Controller Components:- Direct the Action

Model Components :- Access Data & System

View Components: What the user see

The Architecture & Basic flow of Struts 2

Basic Flow Description

User sends a request for the action.

Controller Invokes the Action Invocation.

Action Invocation invokes each interceptors and action.

A result is generated.

The result is sent back to the Action Invocation.

A HTTPServletResponse is generated.

Response is sent to the user.
