Description

RESTful Services Fundamentals is a free online course that has been specifically prepared to teach you about the history, as well as common elements of distributed computing. Are you aware that there are three common elements of distributed computing? Upon the commencement of this course, you will be introduced to the origins and goals of Service Oriented Architecture (SOA). You will also learn about the evolution of web services. When working with the basic format of HTTP functions, you should be able to identify the HTTP methods and their functions. It is also important to learn about the characteristics of HTTP requests or response methods. The functions of the initial response line and the elements of the HTTP entity will also be introduced to you in this course. Prepare yourself to learn about the concepts, different implementations, and features of JAX-RS, as well as how to build a REST web service using JAX-RS.

If you want to learn about how JAX-RS uses path variables and data type matching through regular expressions, then you should complete this course. You will also be able to identify the functions of path and query parameters in Java. This course can help you analyze the functions of annotations, as well as how to target path parameters in a path. It is also imperative to learn how to specify a producer's annotation and how REST resources are created in JAX-RS. You will be able to learn about the context annotation element in REST resources. What about using instance per request and the singleton approach for your web app? You will need to know the difference between them and how they fit with your requirements. It is also imperative that you learn about the concepts of sub-resources, and how REST resolves sub-resources. To improve your knowledge, you will also become familiar with how to build a REST service that acts as a delegate pattern within an infrastructure.

Furthermore, you can also learn how to submit a form to a REST service. Do you know the best practices to map exceptions in a particular status code? You will also learn how to build a response program, as well as how to take total control of responses. Completing this course will help you gain vital knowledge about the consolidated methods for REST infrastructure using the response builder. While completing this course, you will be able to understand the process behind the marshalling of JSON and JAX-RS. The JAX-RS facilities for handling exceptions, along with the best practices to map exceptions to a particular status code will also be covered in this course. This free online course will be of great interest to students, researchers, and anyone with an interest in understanding RESTful services fundamentals and their relevance in programming. So, register for this course and start your next learning journey today.
