Restlets

Restlets are a Java library that simplifies the development of RESTful web services. They provide a higher-level abstraction over the Servlet API, making it easier to map URIs to Java code and handle HTTP requests and responses. Restlets are designed around the concept of a "Restlet" object, which represents a component that can handle requests and generate responses. These Restlets can be chained together to form applications, allowing for modular and composable service design. The library supports various protocols beyond HTTP, including TCP and SMTP, though HTTP is its primary use case. Key features include content negotiation, support for various data formats like XML and JSON, and built-in mechanisms for routing and filtering requests. Restlets aim to make RESTful service development more intuitive and efficient for Java developers by abstracting away much of the low-level HTTP handling.
