Overview

You can use COBOL and Java together, by coding the calls using the supplied support libraries. Java itself provides access to other technologies, such as Remote Method Invocation (RMI) and Java Naming and Directory Interface (JNDI) which enable you to distribute objects across different machines.

You can use COBOL and Java together by:

You can use Server Enterprise Edition with or without Enterprise Server for running the other types of applications that use both COBOL and Java programs.

The Java language defines its own data types, which are different to the ones used in COBOL. The COBOL run-time system automatically converts between COBOL and Java types whenever you call Java from COBOL or COBOL from Java. Where a COBOL data type cannot be translated directly (for example, edited fields), it is under some circumstances translated to a string. See the chapter Java Data Types.
