What you will learn
 

After completing this course, the student should be able to:

  • Understand the REST style of software architecture
  • Describe the advantages and disadvantages of applying RESTful design strategies to various scenarios
  • Implement RESTful services using the JAX-RS Java specification
  • Create JAX-RS services that use various types of request/response content
  • Compare and contrast REST with RPC, SOAP, and other similar communication strategies
  • Apply fine-grained control of the responses returned from JAX-RS services
  • Use various techniques to implement clients of RESTful services
  • Apply Java EE security to JAX-RS services

Audience
 

This course is applicable for Architects and Developers that need to design and develop RESTful web services using JAX-RS.

Prerequisites
 

Experience with Java programming is required. Experience with Eclipse/RAD is useful but not required. For those that might need this Java or Eclipse/RAD experience the following course is suggested:

  • WA1278 Introduction to Java Using Eclipse

An understanding of basic web architecture and the HTTP protocol. Prior experience with RPC-style services such as Web services, Java RMI, COM objects, etc. is helpful, but not required.

Duration
  2 days.
