Project Overview

TaskManager is a backend application designed to manage tasks, users, and task statuses. It exposes RESTful endpoints for CRUD operations on tasks, user registration/login, and status retrieval. The backend is built with Java Servlets, Hibernate ORM, and MySQL, and is ready to be deployed on a Java EE server (e.g., GlassFish).

Features

• User registration and login
• Task CRUD (Create, Read, Update, Delete)
• Task status management
• Hibernate ORM for database operations
• RESTful API with JSON responses
• CORS enabled for frontend integration

Tech Stack

• Java EE (Servlets)
• Hibernate ORM
• MySQL (Database)
• Gson (JSON serialization)
• GlassFish (or compatible Java EE server)
• Maven/Ant (build tools)

• POST /api/user/login — User login
• POST /api/user/register — User registration

Tasks

• GET /api/tasks — Get all tasks
• GET /api/tasks/{id} — Get task by ID
• GET /api/tasks/user/{userId} — Get tasks by user
• POST /api/tasks — Create a new task
• PUT /api/tasks/{id} — Update a task
• DELETE /api/tasks/{id} — Delete a task

Task Status

Setup & Installation

1. Clone the repository:

   git clone https://github.com/cusaldmsr/TaskManagerApp-Backend.git

2. Configure the database:
   • Create a MySQL database named task-manager.
   • Update src/java/hibernate.cfg.xml with your DB credentials if needed.
3. Build the project:
   • Use NetBeans, Ant, or your preferred Java IDE to build the project.
4. Deploy:
   • Deploy the generated WAR file to GlassFish or another Java EE server.

Usage

• Use tools like Postman or a frontend app to interact with the API endpoints.
• Ensure the server is running and accessible at the configured base URL.
