A simple web chat

The application was created for learning purposes.

In general, application now has 3 layers to use database:

1. Util to get connections from connection pool and execute updates and queries
2. DAO to perform CRUD and specific operations
3. Service to fulfil CRUD and specific operations with business logic

• Java
• Servlet
• JSP
• JSTL
• TomCat Server
• MYSQL Database
• JDBC
• MVC Pattern
• DAO Layer
• Util Layer
• Service Layer
