Audience

 

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.
