Listers,
For brevity ... I've been trying to get the Standalone Java vol 2 example of
JAVA calling COBOL (and assembler) via a
C glue working, unsuccessfully ..
I'm on a z/OS 2.2 box, Java 7 x64 only .. I can install 31bit java am hoping I
won't be limited to that ...
I've compiled my skeletons, both assembler and COBOL under native z/OS and
included RENT, DYNAM(DLL) and AMODE64.
For the Java part .. it's a simple javac programname.java followed by a javah
programname (class name)... for the
C part ... I've been using the below ..
c89 -c -o programname.o -W "c,langlvl(extended)",lp64 -W c,expo,lp64,dll
-DNEEDSIEE754 -DNEEDSLONGLONG -I/usr/lpp/java/J7.0_64/include programname.c
c89 -Wl,lp64,dll -o libprogramname.so programname.o
"//'HLQ.PDSE.OBJ(COBOLPROGRAM | ASSEMBLERPROGRAM)'"
With the 'lp64' included .. for the 2nd step (link) .. I keep getting ..
IEW2480W A711 EXTERNAL SYMBOL CEELLIST OF TYPE LD WAS ALREADY DEFINED AS A
SYMBOL OF TYPE LD IN SECTION CEEBLLST.
IEW2482W A712 THE ORIGINAL DEFINITION WAS IN A MODULE IDENTIFIED BY DDNAME
C8921. THE DUPLICATE DEFINITION IS IN SECTION CELQLLST IN A MODULE
IDENTIFIED BY DDNAME SYSLIB.
IEW2491E 9373 CLASSES C_WSA and C_WSA64 ARE BOTH PRESENT IN THE MODULE.
FSUM3065 The LINKEDIT step ended with return code 8.
I do see that both, the COBOL and assembler objects (under z/OS) are amode 64 /
rmode any ... I do not know how to do
the same under USS but am going by the options provided to 'c89' ...
If I remove the 'lp64' option ... it compiles / links fine .. but when I try to
run (java programname) .. I get a class not found error
followed by a java.lang.unspecifiedlinkerror ... this is on the java
System.loadLibrary statement ... when I changed it to
System.load specifying the full path ... I got an EDC5253S An AMODE64
application is attempting to load an AMODE31 DLL load
module ..
Any advice / direction would be appreciated ...
Kind Regards.
Jim
