webforum's Introduction

Web Forum

This is a simple Web Forum using Java Servlets and PostgreSQL.

It was created as the final peer-reviewed assignment for a MOOC on Java advanced concepts on Coursera.

DISCLAIMER: This application is not supposed to be deployed. It's intended just a didactic exercise in Java programming.

Demo

Here is a simple Youtube video demonstrating basic functionality (in Portuguese): https://www.youtube.com/watch?v=qvY-XcWJtRA
