This variable is designed for those calling a Java program from COBOL via the C$JAVA library routine. In this variable, specify the name of the DLL that exports the Java Native Interface (JNI) API for loading the JVM. In the case of JRE 1.4.2_04, the file is called jvm.dll or libjvm.so. If the path to the DLL is in the Path environment variable, the filename is sufficient here; otherwise, this name should be fully qualified with the path. See C$JAVA for more information.
See Calling the C$JAVA Routine for information on calling Java from COBOL using C$JAVA.
