Java Servlet Login and Display

Most web apps start with system Login and data Display.

This simple app serves both purposes by Building backend with Tomcat 7 & MySQL 5 for simple Login system and Displaying responsive Data Table with Bootstrap 3. The system login supports OAuth 2.0 authentication as well as username/password authentication.

A user can log in to this simple web application using username/password credential or through a third-party authentication provider such as idQ Trust as a Service (idQ TaaS) or Google Identity Platform via OAuth 2.0 protocol.

Installation

• Create MySQL database through script 'createtable_composite.sql' inside 'database' folder.
• Input MySQL database login credential in 'src/main/java/LoginDao.java'.
• Input OAuth 2.0 authentication credential in 'src/main/resources/Oauth2.properties'.
• Execute command "mvn tomcat7:run" to run the standalone web server.

OAuth 2.0 Login Demo

• Access the link "https://localhost:8443" or "https://your-web-hostname:8443" for OAuth 2.0 login
• Click idQ Sign In
• You are redirected to idQ TaaS login screen
• Scan idQ QR code using your idQ Trusted Device
• You will be redirected back to reach the home screen of employee information if you have been authenticated by idQ TaaS successfully via OAuth 2.0 protocol.
