Web-Based Complaint Management System using JSP

📌 Project Overview

This project is a Web-Based Complaint Management System (CMS) developed as part of the IJSE Graduate Diploma in Software Engineering (GDSE) - Advanced API Development module. The system is designed for the Municipal IT Division to enable employees to submit, view, edit, and delete complaints, and for admins to manage all complaints, update their status, and add remarks. The application strictly adheres to synchronous HTTP form submissions (GET/POST) using JavaServer Pages (JSP), Jakarta EE, and MySQL, following the Model-View-Controller (MVC) architecture. Asynchronous mechanisms like AJAX are not used, per the assignment constraints.
