If you need to launch the Java virtual machine and invoke methods, it will be 
*much* easier to use C or C++ since you need to use "JNI" and the include files 
are provided and you need a LE XPLINK linkage and runtime environment.  I've 
done that and it works fine (both 31 and 64 bit SDK versions).

Another option would be to use Enterprise COBOL which has a Java JNI interface 
included.
