Web Services

I have been taking a training on J2EE and the instructor was kind enough to spend an additional hour to brief me about the latest buzz word - Web Services. He gave a quick overview about this and did a demo (writing actual code) for using a Web Service already available and to develop a Web Service all using Apache's AXIS.

Wow! how quick is it to develop one. I recall the olden days when I used to write applications in RMI trying to cram the classes and methods and interfaces. With AXIS, you create the code in no time. Everything in Web Services revolves around the WSDL file (WSDL stands for Web Services Development Language) and SOAP (Simple Object Access Protocol)

Very interesting to learn!
