Terminating the Java VM
When an adapter class is no longer used, the Java VM must be terminated. Use the
JVM-TERMINATE method of the FJ-JAVA-CONTROL class to terminate the Java VM.
A coding sample is shown below:
...
REPOSITORY.
CLASS FJ-JAVA-CONTROL
...
PROCEDURE DIVISION.
...
INVOKE FJ-JAVA-CONTROL "JVM-TERMINATE".

Developing a Multithread Application
A multithread application using an adapter class must connect the current thread to
the Java virtual machine (VM). When the multithread application is terminated, the
current thread must first be disconnected from the Java VM.
Use the JVM-INIT method or the JVM-ATTACH method of the FJ-JAVA-CONTROL
class to connect the current thread to the Java VM.
To disconnect the current thread from the Java VM, use the JVM-TERMINATE
method or the JVM-DETACH method of the FJ-JAVA-CONTROL class.
A multithread application sample is shown below:

Generating an Object
Generate an object by invoking the adapter class factory method corresponding to
the constructor. Generate the factory method with the following name (see
"
Constructor
").
