You can use OO syntax in a COBOL program to implement a Java 2 Platform, Enterprise Edition (J2EE) client. You can, for example, invoke methods on enterprise beans that run in the WebSphere® for z/OS environment.
Before you run a COBOL J2EE client, you must set the Java system property java.naming.factory.initial to access WebSphere naming services. For example:
export COBJVMINITOPTIONS ="-Djava.naming.factory.initial=com.ibm.websphere.naming.WsnInitialContextFactory"
