A unique web application works through the interchange of three major parts: the front-end, back-end, and information base. The front-end, or UI (UI), contains all that the client associates with, created utilizing languages like HTML, CSS, and JavaScript.
Start by structuring the web application’s directories and files. Create a ‘WebContent’ directory to house web pages (HTML, JSP) and resources (CSS, JavaScript files).
The ‘web.xml’ record, situated in the ‘Internet INF’ registry, goes about as the organization descriptor.
Construct the application’s visual elements using HTML for the content structure and CSS for styling.
Enhance the UI with JavaScript, making pages interactive. Implement client-side scripting to validate forms, create dynamic content, and manage DOM elements, providing an immediate response to user actions without server delay.
Use Java servlets for handling client requests and server responses. Servlets interact with the front end, process the received data, execute business logic .
Inside servlets, override methods like ‘doGet’ or ‘doPost’ to handle respective HTTP methods.
Java Database Connectivity (JDBC) is an API that manages interactions between Java applications and databases.
Utilise JDBC to connect to your database. Load the JDBC driver, provide the database URL, and specify credentials to create a connection, through which you can execute SQL commands.
