I found a Power Point "Enterprise COBOL and Java Interoperation". Nick
Tindall and Stephen Miller It's advice is to use a OO COBOL Class as a
wrapper to call procedural COBOL. In CICS I have sucsessfully called
procedureal COBOL from Java, but using the JCICS classes.
What is the JCICS doing to allow me to call my old COBOL routines in a PDS
using just a COMMAREA as a parameterr?

Also, keep in mind that JNI doesn't support passing objects, just
primitives.

Warning, I have never done this and I don't speak COBOL, but... You need
to make a JNI call from the IBM Java environment into a compiled program
running in an LE-conforming environment. COBOL is (in theory) exactly
that.
All of the examples are probably C, but any language supported by LE
ought to work. You might need to write a C stub to line up the
parameters for your COBOL code and make the call to the COBOL
subroutines from there. I don't think its likely to be brain surgery.
