Exam Hall Seating System Project Overview

The Exam Hall Seating System is a semi-automated web-based application developed to help students quickly find their assigned exam room, floor, and seat number using their roll number. The system reduces confusion during examinations and minimizes the manual effort required by examination staff.

Seating data is entered once by the administrator, after which the system automatically retrieves and displays the required information. The application also supports floor plan visualization, allowing students to identify their exact seating location within the exam hall.

Key Features

Search exam seating details using roll number

Displays room number, floor, and seat number

Visual floor plan support with seat highlighting

Semi-automated seating management

Simple and user-friendly web interface

Reduces time and effort for students and staff

System Architecture

Frontend: HTML, CSS, JavaScript

Backend: Java (HttpServer)

Data Storage: SQLite database (data/seating.db)

Deployment:

Frontend hosted as a static site

Backend deployed using Docker on Render

Technologies Used

Core Java

Java HttpServer

HTML5

CSS3

Bootstrap

Docker

Git and GitHub

How to Run the Project Locally Step 1: Compile Java Files javac src/*.java

Prerequisite: Ensure sqlite3 is installed and available on your PATH. If it is missing, the app will fall back to legacy text-file storage.

Step 2: Run the Java Web Server java -cp src SeatingWebServer

Step 3: Access the Application

Open a browser and navigate to:

http://localhost:8080

Docker Deployment (Backend) Dockerfile FROM openjdk:17-jdk-slim RUN apt-get update && apt-get install -y sqlite3 && rm -rf /var/lib/apt/lists/* WORKDIR /app COPY src ./src COPY data ./data RUN javac src/*.java EXPOSE 8080 CMD ["java", "-cp", "src", "SeatingWebServer"]

On Render, select Docker as the runtime environment and configure the service to use port 8080.

Sample Seating Data Format (legacy import) CS2024001,Room-101,First Floor,S01 CS2024002,Room-101,First Floor,S02 CS2024003,Room-102,First Floor,S01

Advantages

Improves accuracy in seat allocation

Reduces administrative workload

Easy to update and maintain

Suitable for academic environments

Future Enhancements

Fully automated seat allocation logic

Optional integration with external databases (MySQL or PostgreSQL) for larger deployments

Admin dashboard for managing seating data

Student authentication system

Enhanced UI and mobile responsiveness

Project Type

This project is designed as an academic mini project for Computer Science and Information Technology students, demonstrating the integration of a Java backend with a web-based frontend.
