Overview

This course covers how to implement web services with WebSphere 8.5 using the most recent Java standards, JAX-WS for SOAP web services and JAX-RS for REST web services. Since it is possible to use both styles of web services, even within the same application, this course will show the student the strengths of both styles and how to properly implement both types of web services.

  • Testing web services is also more difficult than "normal" web applications so this course covers tools and techniques used to test web services in the labs.
  • This course will be particularly useful for those looking to upgrade existing JAX-RPC Java web services and who want to know the different styles of web services now supported by WebSphere 8.5.
  • Labs are done using the new Eclipse tools for WebSphere.

Skills Gained

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

  • Confidently design XML schema and WSDL.
  • Tell the difference between different SOAP styles (document literal, RPC literal etc.)
  • Implement a Web Service using Eclipse and WebSphere 8.5.
  • Write a Web Services client using standard Java specifications.
  • Secure JAX-WS web services.
  • 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
  • Use various techniques to implement clients of RESTful services
  • Apply Java EE security to JAX-RS services

Who Can Benefit

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

Reviews

vary good online learning. instructor is vary good the way he explained every thing.

Course was great and informative. The instructor had a good flow and was very personable.

Great and very intuitive. Better than the traditional hit the wrong button/lose points.

The instructor really took his time and made sure I was able to understand the concepts.

Great class I learned a great deal from the material. There would seem to a large amount that I need to learn about.
