CHAT_JAVA

Java Chat App with Oracle Database

This MVC project implements a simple chat application using Java, Oracle Database, and JDBC.

Project Structure:

• src/: Contains Java source code for the application logic, including:

    - `dao`: oracle commands to create the needed operations for the chat app
  
    - `controllers`: handles the interaction between the user and the app
  
    - `utilitaire`: connection to database (im using hr database you can change it to your desired db)
  
    - `views`: folder representing the views in client-side
  

• ConnectionPar.properties: Configuration file for the Oracle database connection (username, password, URL).

• presentation-script bd/:

    - `dataBaseScript.txt`: Script to create necessary tables in the Oracle database.
  
    - `presentation.docs`: docs presentation showcasing the project and its features.
  
    - `diagramme de classe.png`: Class diagram illustrating the application's components and relationships.
  

• ojdbc6.jar:driver for connecting to Oracle Database (ensure compatibility with your chosen Oracle version).

Dependencies:

• Java Development Kit (JDK)
• Oracle Database server and client libraries

Getting Started:

1. Install the Oracle Database server and client libraries: Follow Oracle's installation instructions for your environment.
2. Set up the database:
   • Create a database user with appropriate permissions.
   • Execute the create_tables.sql script in the presentation-script bd/ folder to create the necessary tables.
   • (Optional) Execute the insert lines script to insert some sample data (useful for testing).
3. Configure the database connection:
   • Open db.properties and update the following properties:
     • db.url: Oracle database URL (e.g., jdbc:oracle:thin:@localhost:1521/your_database_name)
     • db.username: Database username
     • db.password: Database password
4. Compile and run the application:
   • Open a terminal in the project directory.
   • Compile the main class (com.example.chat.Server or com.example.chat.Client) using javac -cp .:jdbc/* *.java.

Additional Notes:

• You can customize the application's behavior and features by modifying the Java source code.
• Consider implementing security measures (e.g., authentication, authorization) based on your requirements.
• Refer to the class diagram and presentation for a deeper understanding of the project.
• This is a basic example, and you may need to expand it based on your specific needs and functionalities.

Note: This README file doesn't contain actual code snippets for the Java classes or SQL scripts. You need to implement those based on your specific functionality and database design.
