Java Web Services –  J2440  (3 day course)

With the maturing of Web Services and associated technologies, such as SOAP, WSDL, XML-RCP and XML-M, significant value is apparent for the use of Web Services for non-API based application integration. As standards evolve and a more uniform definition of Web Services appears across the board, better guidelines for when to enable an application as Web Service and when not to are becoming clearer.

In this course, we discuss the evolution of Web Services and checkpoint its current status. We will learn about SOAP and WSDL and understand their relevance and significance. We will then consider the XML-M and XML-RPC and how to use them for creating Web Services. We will also discuss emerging trends in Web Services and see where they are currently headed.

The course is lab intensive with attendees implementing several web services using the various technologies discussed
