OAuth2 Authentication for Jakarta EE Applications

Securing enterprise Java applications does not mean you have to build complex user management systems from scratch. By leveraging OAuth2 providers, you can delegate authentication to trusted external identity platforms while keeping your Jakarta EE applications secure and lightweight. This text-based course guides you through the foundational concepts of OAuth2 and Jakarta EE security, helping you set up external application registrations, manage credentials securely, and integrate these providers with modern Jakarta EE authentication mechanisms. What you'll learn: 1. Understand the core principles of OAuth2, OpenID Connect, and Jakarta EE security frameworks. 2. Configure application registrations and consent screens in modern cloud provider consoles. 3. Generate and securely manage OAuth2 client credentials and redirect URIs. 4. Implement Jakarta EE Security APIs to intercept requests and handle authentication tokens. 5. Apply modern security best practices, including credential encryption and secure session handling. You will start with essential terminology and security concepts before moving step-by-step through configuration workflows. Through clear written explanations and structured configuration examples, you will gain a practical understanding of end-to-end authentication flows. This course is designed for Java developers new to enterprise security and Jakarta EE authentication, with no prior experience with OAuth2 required. Start reading today to build secure, modern Java applications with industry-standard authentication.
