We have following problem:

- we are using the testversion of VC4.0

- we try to call a cobol program from java

- so we created a JVM-Project with two cobol files 

-> program1.cbl and copy1.cpy 

- and a Java-Project with

-> CobolCallDemoDefaultPackage.java within a java-Project.

- now we tried to call Program1 with Copy1 as parameter, but we get the following compiler-error:
"The type com.microfocus.cobol.program.Reference cannot be resolved. It is indirectly referenced from required .class files"

public static void main(String[] args) {
PROGRAM1 program1 = new PROGRAM1();
Copy1 copy1 = new Copy1();
copy1.setEDatum("20180101");

program1.PROGRAM1(copy1);  <- doesn't work: The type com.microfocus.cobol.program.Reference cannot be resolved. It is indirectly referenced from required .class files

System.out.println(copy1.getADatum());
}

Where is our mistake ?

Thanks for any hint !

Did you add the COBOL JVM run-time files to your Java project?

Please see the docs here: and the example here:
