19 Aug 2008 This tutorial describes how to write Enterprise Generation Language (EGL)
code that calls programs (RPG, COBOL, CL, CL Commands, or programs written in any
supported language) on your IBM® System i5™ machine. The process for
you to call an existing IBM i™ program from EGL has been very much improved
in IBM® Rational® Developer for System i™ V7.1 (and later), and
is incredibly simple. EGL leverages the IBM i Toolbox for Java™, which in turn utilizes the System i5’s Remote Command Host Server (QZRCSRVSD in the QSYSWRK subsystem).
Before you start
Important Note: Walk through this scenario and others online as part of the Enterprise
Modernization Sandbox for IBM i
About this tutorial
This tutorial shows you how to do the following:
- Create EGL application that calls IBM i programs (RPG, COBOL, CL and CL Commands).
- Learn to use IBM® Rational® Business Developer to build and test EGL application.
Objectives
This tutorial will guide you through the following steps:
- EGL and the IBM i runtime environment.
- Configuring your EGL Web Project to access the IBM® System i5™ server and call a program
- The actual code to call an IBM i program
- Debugging both RPG and EGL code
Prerequisites
You should be familiar with one of the IBM® Rational® Software Delivery Platform products
that Rational Business Developer supports, and have knowledge of IBM® System
i™ applications.
