									Understanding WebSphere

Duration: 2 Days

This two-stage course introduces the world of WebSphere. In the first part, the Enterprise Java (J2EE)
platform (the basis for the WebSphere architecture) is explained. The integration of Java with existing
(enterprise) systems is also covered. The second part of the course is designed for mainframe (z/OS)
users who, if they have not already encountered a WebSphere Application Server (WAS) in their
organisation, are likely to in the near future. This one-day course introduces and explaind the
WebSphere Application Server for z/OS from the perspective of the experienced mainframe
professional. This course is particularly appropriate for all applications architects, project managers,
programmers and administrators who are going to encounter web applications in their environment.

Who should attend?
Application programmers and administrators who are going to use web applications in an enterprise
environment, based on a WebSphere platform.

Some familiarity with Internet concepts and Java would be an advantage, but is not mandatory. for day
two, an understanding of the z/OS environment is required.

Delegates will learn how to
On successful completion of this course, attendees will be able to:

   discuss the architecture and possibilities of Enterprise Java (J2EE)

 describe the pros/cons of different solutions for typical business problems

 list the most recent J2EE APIs

 understand the integration of Java with existing enterprise systems

 list the products and tools in the J2EE domain

 describe the set-up of this environment: web, web applications, web servers , etc.

 explain the role of Java and the importance of an architecture combined with application
 describe the role of WebSphere Application Server
