Service Oriented Architecture (SOA) Immersion Bootcamp for Java
Course Length - 5 Days
Course Description
The chief goal of this class is to teach how to build a SOA application from ground up. It covers the full lifecycle of a SOA project - requirements gathering, design, implementation and testing.
If you are getting started with SOA development, this class offers a wonderful opportunity for your development team to get a concrete idea for how a SOA application is built.
The course consists of both pen and paper labs and hands-on labs using IBM WebSphere Integration Developer V6.0 to build, test and run SOA applications.
Course Prerequisites
Java programming. Beginner level knowledge of J2EE and XML.
Who Should Attend?
J2EE developers who are responsible for developing SOA based application integration solutions.
Architects who will like to get hands on practical experience developing a full SOA application from start to finish. For a more indepth SOA architecture related training, please use WA1471 Service Oriented Architecture (SOA) for Architects.
