Within the JVM COBOL project (CJVM), create an output folder to store the JAR output. The JAR will be created by a build at a later point:
The Properties for CJVM dialog box is displayed.
The build configuration options for the project are displayed in the right-hand pane.
This creates a packaging target in the project's build file, and enables the other packaging options.
This creates a new folder, relative to the project folder, which you can see in COBOL Explorer after the project is next built. You can leave the JAR file name option at its default, CJVM.jar.
