Topic 7: Development of Enterprise Application

Goal

To enable students to integrate all previously learned components (Servlet, JSP, JavaBean, JDBC) into a complete enterprise web application using the MVC architecture.

🎯 Learning Objectives

Students should be able to:

1. Design a complete enterprise web application using MVC architecture
2. Integrate Servlet, JSP, JavaBean, and JDBC into a single system
3. Develop functional modules such as login, registration, and CRUD
4. Apply appropriate Java EE design patterns
5. Construct a working multi-tier web application

📌 Topics to Cover

1. Choosing Java EE Architecture
   • MVC (Model-View-Controller)
   • Layered architecture
2. Java EE Design Patterns
   • MVC pattern
   • DAO (Data Access Object) concept
3. Designing Web Components
   • HTML forms (View)
   • JSP pages (View)
4. Developing Backend Components
   • Servlet (Controller)
   • JavaBean (Model)
5. Database Integration
   • JDBC connection
   • CRUD operations
6. System Integration
   • Connecting all components
   • Flow: User → JSP → Servlet → Database → JSP

🛠️ Hands-on Activity

Activity: Complete Student Management System (MVC Implementation)

Students are required to develop a complete web-based system with multiple modules.

1. System Modules

   • Login Module
     • User login using session
   • Registration Module
     • Register new user
   • Student Management (CRUD)
     • Add student
     • View student list
     • Update student
     • Delete student
   • Dashboard
     • Display summary (e.g., total students)

2. Apply MVC Architecture

   • Model (JavaBean)
     • Student.java
   • Controller (Servlet)
     • StudentServlet.java
   • View (JSP)
     • list.jsp, form.jsp, dashboard.jsp

3. Database Integration

   • Use JDBC
   • Table: student
   • Perform full CRUD operations

4. System Flow

User → JSP (Form) → Servlet → JDBC → Database → JSP (Display)

5. (Optional Enhancement)
   • Add search function
   • Add validation
   • Improve UI design

Expected Output

Students should produce:

1. Complete working web application
2. Multiple JSP pages
3. Servlet controller(s)
4. JavaBean model
5. Database integration (CRUD working)
