Learn how to use IBM® WebSphere® Developer for System z Version 7 to create and debug Java™ applications that will run on z/OS (System z). This article, for Java developers who are already familiar with the Eclipse development environment, shows that writing Java applications for System z is very similar to writing for other environments.

To get the most out of this article, you should already have acquired and installed WebSphere Developer for System z V7. However, if you do not yet have access to WebSphere Developer, you can view the screenshots to get a good idea of how you will be able to work with the product.

In this article

• Get started with WebSphere Developer for System z
  
  
• Write a simple Java application
  
  
• Run and debug your the Java application locally
  
  
• Run and debug your the Java application on System z
  
  
• Write a Java application with an affinity for System z
  
  
• Run and debug this second Java application locally
  
  
• Run and debug this second Java application on System z
  

Background

Eclipse provides a productive development environment for writing applications. WebSphere Developer for System z extends the Java support to z/OS, making it as easy to create and debug Java applications for z/OS as it is to create and debug Java applications for any other platform.

Readers should have an understanding of Java programming and the Java development environment provided by Eclipse or Rational® Application Developer Version 7, and be familiar with basic z/OS concepts.
