I have made few changes in test program. Added errorno and dlerror() just for error checking

any pointers why the linking error?

Then you must link it explicitly with dl, try

 cc -o testjvm2 testjvm2.c -ldl

Thanks a lot andryk. It worked on solaris.

I tried the same program on hp-ux.
On hp-ux it fails to load jvm library.

Any pointers why it is failing on hp-ux?

hi ,
In Hp-Ux , when creating a shred lib we have to use +z option to create an object file for shared lib ,
for ex:
$cc +z -c share.c -o share.o

$ld -b share.o -o share.sl ( to create a shared lib )

Just try this and let me know !

Thanks
Narendra

Hi Narenadra,
I am not creating shared library. I am just opening it in my program with statement
retval = (int)dlopen("libjvm.sl",RTLD_LAZY);
