WA1281 Introduction to Web Services Training and Courseware

Quick Enroll

Primary goal of this course is to explain how you can benefit from Web Services. It proceeds to explain various topics such as SOAP, WSDL, UDDI, JAX/RPC and WSIF. For each technology, we explain the primary motivation behind it and how it may help you solve a problem. Students will use this training to learn to develop the required WS components (both server and client side). Additionally, an overview of SOA (Service Oriented Architecture) will be provided.

Topics
	Motivation behind Web Services Buisness problems ideally suited for a Web Services based solution SOAP WSDL JAX/RPC UDDI Ways to develop a services Ways to develop a client

What you will learn
	After completing this course, the student should be able to: Determine if Web Services is a right fit for a specific problem Decide how to develop a service Decide how to develop a client

Audience
	Architects and project managers who will like to get introduced to the technology and understand its use and potential. This is not a programming course.

Prerequisites
	Some idea of clients server computing. There is no programming experience required.

Duration
	1 day
