JSP & Servlet Project Pro: 50 Industry-Ready Web Applications for Aspiring Java Developers (VOL-5)

Build Secure Enterprise Web Applications Using JSP, Servlets, JDBC, MySQL, SHA-256, JavaMail API, Apache Tomcat & Modern Authentication Techniques

Author: Anshuman Mishra

Security is no longer an optional feature in modern software development—it is a fundamental requirement. Every web application that handles user accounts, confidential information, online transactions, or business operations must implement strong authentication, secure session management, password protection, and defenses against common cyber threats.

JSP & Servlet Project Pro: 50 Industry-Ready Web Applications for Aspiring Java Developers (VOL-5) focuses entirely on web application security, teaching readers how to build secure Java web applications using practical, real-world projects based on modern authentication and cybersecurity principles.

Rather than presenting security concepts only through theory, this volume adopts a project-based approach where every chapter demonstrates how enterprise applications protect user data, authenticate users, validate requests, and defend against common web vulnerabilities.

Each project reflects industry best practices and prepares students to develop secure applications suitable for academic projects, internships, software engineering careers, and enterprise environments.

Learn the Foundations of Secure Web Development

Security begins with understanding how vulnerabilities arise and how secure software is designed.

Readers gain practical experience with:

Secure Authentication
User Authorization
Password Security
Session Management
Input Validation
Secure Database Access
Request Validation
Secure Coding Standards
Error Handling
Web Security Best Practices

These concepts form the foundation of professional Java web application development.

Build a Secure Login System Using SHA-256

Authentication is the first line of defense in any web application.

This project demonstrates how to create a secure login system using SHA-256 password hashing.

Topics include:

User Registration
Password Hashing
SHA-256 Encryption
Secure Authentication
Login Validation
Password Comparison
Database Storage
Session Creation
Logout Functionality
Secure User Access

Readers understand why passwords should never be stored in plain text and how secure authentication mechanisms protect user accounts.

Develop OTP-Based Email Verification

Email verification is widely used by modern applications to verify user identities.

Readers build a complete verification system featuring:

OTP Generation
Email Verification
JavaMail API Integration
Secure Registration
Verification Workflow
Expiration Handling
User Confirmation
Verification Status
Authentication Flow
Database Updates

This project closely resembles the account verification process used by leading online platforms.

Create a Password Reset Module

Password recovery is an essential feature of every secure application.

This project teaches:

Forgot Password Workflow
Secure Reset Requests
Token Generation
Email-Based Password Reset
Reset Validation
Password Update
Session Security
User Authentication
Expiration Control
Secure Database Operations

Readers learn how enterprise applications safely handle password recovery without exposing sensitive information.

Implement Session Timeout and Auto-Logout

Session management protects users from unauthorized access after inactivity.

Readers develop a secure session management module including:

Session Creation
Session Monitoring
Timeout Configuration
Auto Logout
Inactive User Detection
Secure Session Handling
Session Invalidation
Login Protection
Activity Tracking
User Notifications

The project demonstrates techniques commonly implemented in banking, healthcare, and enterprise software.

Integrate CAPTCHA Protection

Automated attacks and spam submissions are common challenges for online applications.
