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.
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.
Prerequisites
 

Previous experience with Web Services is necessary. Students should know SOAP, WSDL and how to develop a basic Web Service. WA1562 Web Services Development Using RAD v7.0 is highly recommended.
