Project Structure

• controller: Contains servlet classes responsible for handling user requests:

  • Register.java: Handles user registration.
  • Login.java: Manages user authentication.
  • Home.java: Redirects to the homepage.
  • Profile.java: Displays and updates the user profile.
  • DeleteUser.java: Deletes user data.

• model: Contains data-related logic and models:

  • User.java: JavaBean class representing the user entity.
  • UserDatabase.java: Handles database operations such as user creation and lookup.

• util: Provides utility classes:

  • DataUtil.java: Contains logic to establish a connection to the MySQL database.

View Layer (JSP Files)

• register.jsp: Registration form interface.
• login.jsp: Login form interface.
• home.jsp: Main homepage after login.
• dashboard.jsp: User dashboard view.
• profile.jsp: Displays and edits user profile.

Database Design

The project uses a MySQL database to store user data. The following table is used:

User Table:

Column	Data Type	Description
id	INT	Primary key, auto-increment
name	VARCHAR	User's full name
email	VARCHAR	User's email (unique)
password	VARCHAR	User's encrypted password
profile_picture	VARCHAR	Path to the user's profile picture

Features Implemented

• User Registration:

  • Validates password match and unique email.

• User Login:

  • Validates credentials and starts a user session.

• Edit Profile:

  • Allows users to update personal information like name and profile picture.

• Logout:

  • Clears the user session using session.invalidate().

• Account Deletion:

  • Allows users to delete their accounts and remove all data from the database.
