Calling Java programs or methods

This chapter describes how a Java program can call a COBOL program using isCOBOL.

A COBOL program can call a Java program using the CALL statement as long as the Java program implemenents the com.iscobol.rts.IscobolCall interface and exposes the following public method:

public abstract java.lang.Object call(java.lang.Object[])

Sample programs for this task are installed with isCOBOL in the subfolder sample/is-java/iscobol-call-java.

A COBOL program can invoke any Java method using object oriented syntax or the INVOKE statement.

Sample programs for this task are installed with isCOBOL in the subfolder sample/is-java/iscobol-call-java-object.
