JSP & Servlet Project Pro: 50 Industry-Ready Web Applications for Aspiring Java Developers (VOL-6)

Build API-Driven Java Web Applications Using REST APIs, Google Maps, JavaMail, Twilio, JSON, JSP, Servlets, JDBC & MySQL

Author: Anshuman Mishra

Modern web applications rarely operate in isolation. Today’s software systems communicate with payment gateways, mapping services, weather providers, email servers, SMS platforms, cloud services, and countless third-party APIs to deliver dynamic and intelligent user experiences.

JSP & Servlet Project Pro: 50 Industry-Ready Web Applications for Aspiring Java Developers (VOL-6) focuses on one of the most valuable skills in modern software development—integrating external APIs and cloud services into Java web applications.

Rather than learning API concepts through theoretical examples, readers build complete, industry-inspired projects that demonstrate how professional software communicates securely with external platforms using REST APIs, JSON data, HTTP requests, authentication mechanisms, and third-party service integrations.

Each project reflects real business applications and prepares students for enterprise software development, internships, placement interviews, freelance development, and modern full-stack Java careers.
