Java Web Services Course

About this 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. The Java Web Services course is for Java programmers. It will teach you how to develop web services in Java, and how to write client programs that use web services. You will also learn about the various standards involved, the difference between SOAP and REST web services.
