Banking System - Java Servlet

Java Apache Tomcat is one of the web servers that allows the capabilities of the servers that host applications in a request-response programming model by responding to a particular type of network request, commonly through a HTTP request.

To understand more about web servers and how they interact with the client side, August Eggers and I demonstrate our understanding of how the web server works; we build an online banking application to connect to the online Java Servlet component with authentication and web components. Servlets let us have a dynamic container for the web, and they are the easiest way to maintain sessions through the use of cookies!

Features

• Identify the user on the server and create a state through sessions/cookies
• Allow users to add multiple different types of accounts into their banking profile: saving, checking, and brokerage
• Allow users to deposit, withdraw, and transfer funds between accounts
• Allow users to remove their accounts only if there is no fund left
• Display the transaction history of the accounts

Contribution

• Writing Java objects to be used for online banking applications
  • Adding banking users and with its unique ID
    • Ability to add and remove accounts
    • Ability to login to your servlet to identify the user to the server and create state through sessions/cookies
    • Ability to view account transaction history
    • Ability to deposit, withdraw, transfer, and view account balances
  • Storing Java objects to look up their corresponding banking accounts
• Receiving & computing requests and giving their corresponding responses back to the client
• Writing an online servlet component with authentication and web components
• Designing all HTML pages with addition to CSS and sending correct META tags back to the client

Usage

To compile the every Java Banking System file, go to the webapps/banking/WEB-INF/classes folder and type in:

javac -classpath ../../../../lib/servlet-api.jar *.java

To start up or shut down the server, go to the bin folder and type in ./startup.sh or ./shutdown.sh
