Advanced Jakarta Servlets: Request/Response Wrappers and Dispatcher Types

Request and response wrappers are your go-to tools for customizing, filtering, or sanitizing data without altering the core servlet logic. Dispatcher Types give you fine-grained control over how filters are applied based on the request context, like direct access, internal forwarding, inclusion, errors, or asynchronous processing.In this course, learn about dispatcher types and how request and response wrappers enhance servlet filters. Explore how input validation filters are used to clean user-submitted data before it reaches your servlets and implement filters to validate usernames and passwords for streamlined authentication. Next, learn about XSS protection, how to create response wrappers and filters to manage response headers consistently across your application, and how to transform servlet responses from XML to JSON.Finally, learn how filters are configured to modify response formats based on your applications needs. Explore the default dispatcher type to understand filter execution control and learn to configure filters to respond to FORWARD and INCLUDE dispatcher types.
