FUJITSU J Adapter Class Generator - Manual (Page 10)

10 Chapter 1. Outline of J Adapter Class Generator
What is the J Adapter Class Generator?
Taking advantage of the object-oriented function, Fujitsu NetCOBOL enables
programming using class libraries . The Fujitsu NetCOBOL also provides many useful
foundation classes. Meantime, as Java becomes popular, many Java class libraries
are also provided. However, the class structure varies from language to language
and therefore Java class libraries cannot normally be used from COBOL.
The J adapter class generator provides a framework that enables COBOL to use Java
classes.
The J adapter class generator enables a COBOL program to:
Use a Java class library. •
•
•
•
•
Call a Java application.
Use an application program interface (API) provided for Java.
The J adapter class generator enables COBOL to be used for systems that previously
could only have been implemented in Java.
Use of the J adapter class generator is recommended in the following situations:
Constructing a COBOL system using Java common parts such as EJB
components.
Constructing a COBOL system using whole Java applications.
An outline of the J adapter class generator is given below:
