Tutorial Project Goals

The goal of this tutorial is to show you how to invoke an existing COBOL program in a Java environment.

In this tutorial, you will learn how to:
  • Install supplementary software for the server runtime and web projects.
  • Obtain the COBOL and Java tutorial files.
  • Compile a legacy COBOL program in an Eclipse project.
  • Create the various Java components in the dynamic web project that drives the COBOL program.
  • Configure Java to recognize the COBOL JVM runtime.
  • Run and debug both the COBOL and Java elements using Eclipse.

Skills Requirements

To succeed with this tutorial, you need a basic understanding of COBOL and Java programming. In addition, you need a good understanding of the Eclipse IDE.


This tutorial is intended for COBOL programmers who wish to modernize their legacy systems using Java in a web-based environment.

System Requirements

Before running this tutorial, you need to have the following software installed:
  • A Java Enterprise Edition server. The tutorial explains how to obtain and install a server.


On completion of this tutorial, you will have gained experience of using Enterprise Developerfor Eclipse to compile, run and debug a COBOL program in a web-based Java environment, thereby assisting you to modernize your current systems. In addition, you will have an understanding of the workings of the Micro Focus Run Unit Manager and the Micro Focus smart linkage facility.
