12 Chapter 1. Outline of J Adapter Class Generator
Therefore, the following restrictions apply to COBOL:
- Listener
Java registers a listener object, in which event processing logic is written,
within an object that generates an event. However, since no COBOL object
can be registered in a Java object, COBOL cannot be used to write listeners.
- Collection class
No COBOL object can be registered in a Java collection class. When using
COBOL objects as a collection, use a COBOL collection class.

Class having a Japanese name
No class name, field name, and method name can include the Japanese
character set.
Invoking COBOL from Java
No COBOL program can be invoked from Java. A COBOL program invoked from
Java can use no adapter class.
