I don't speak Cobol, but from what I understand, Cobol does not have the
ability to call Java methods directly. (Someone correct me if I'm
wrong.) This means that you'd either have to call the JNI APIs to
access the HSSF classes, or you'd have to write all of the code that
talks to Java in RPG, and then call the RPG routines from Cobol.
Maybe a bit academic, but COBOL does have the ability to call Java
methods. It's similar to calling Java using RPG prior to V5R1. I
don't know if you ever tried that, but I'm having a really bad flashback
right now. Brrrr.
It's described in chapter 10 of the COBOL Programmer's Guide in the
section called "COBOL and Java programs". The layout of the JNI
function-pointer structure is defined in QSYSINC/QCBLLESRC member JNI.
(I haven't ever tried calling Java from COBOL; I don't speak COBOL well
enough.)
For sure I would write RPG wrappers to do the Java calls and have COBOL
call the RPG wrappers.
