Create a Class and Build Your Project

Now that you have created a project, you need to provide the COBOL code for the application in a new COBOL class. To do this:

Select the project in the Application Explorer view, and then click File > New > Other.
Expand Micro Focus COBOL > JVM Source Files, and then click COBOL JVM Class.
Click Next.
This opens the New COBOL JVM Class dialog box.

Enter the following details:

Field	Value
Source folder	HelloJVMworld/src
Package*	com.microfocus.example
Name	JVMWorldClass

Note: * A Java package is a mechanism for organizing Java classes, interfaces, and types into namespaces. These entities are stored in a directory structure specified by its package name. In this case, the value "com.microfocus.example" creates the structure <source folder>\com\microfocus\example (Windows) or <source folder>/com/microfocus/example (UNIX).

Click Finish.
This creates a new COBOL program from the supplied templates to hold the code for the class in the src > com > microfocus > example folder in your project. The program also opens in the editor.

Copy and paste the following code into the editor, overwriting the existing text:

      $set ilusing(com.microfocus.example)
       class-id com.microfocus.example.JVMWorldClass public.

       working-storage section.


       method-id main static.

       01 class1 type JVMWorldClass.
      
       procedure division using by value args as String occurs any.
           set class1 to new JVMWorldClass
           invoke class1::instanceMethod
           stop run.
       end method.


       method-id instanceMethod.
       
       procedure division.
           display "Hello world".
           goback.
       end method.
       
       end class.

Click File > Save.
By default, Eclipse is configured to build projects automatically. If this option has been changed, to manually start a build, select the project in the Application Explorer view and click Project > Build Project.
