Java Web Services  Course

A web service is a software program that makes itself available over the internet for another system to use. Web services use a set of international standards for communication between different systems. This course will teach you how to develop web services using Java. You will learn about the various standards involved, the difference between SOAP and RESTful web services, and how to write client programs that use web services.
