Web Services Training Overview
This course goes beyond basic Web Service development and covers advanced topics such as Atomic Transaction, MTOM and Reliable Messaging. If you have already implemented Web Services based application interaction, you will be able to make them more reliable and fault resistant using the techniques mentioned in this class.
This class is meant for the Java developers. If you are already familiar with the JAX-RPC programming model, you will benefit from the coverage of the new JAX-WS API.
Web Services Training Audience
J2EE developers who will like to learn about how to build a Web Services based solution. This class covers many advanced topics that will help them build a solution appropriate for a large business.
Web Services Training Prerequisites
Previous experience with Web Services is necessary. Students should know SOAP, WSDL and how to develop a basic Web Service. Web Services Development Using RAD v7.0 is highly recommended.
Web Services Training Tools Used
The class currently uses IBM tooling for the labs. The concept and theory are vendor neutral. If you wish to take the class using a non-IBM tool please let us know.
