Hi,
First question, what are you running on? The path gives the impression
that it may be HPUX (?). Or is it just Linux?
It looks like libjuh.so is a required dependency, and is available on
your machine in a 32-bit flavour. Are you able to try your case with
real 32-bit eclipse and jre installs (not just passing -D32 to the
64-bit jre)?

Hi Grant,
Thanks for your reply.
Answering to your first question, I am running the application on Linux.
One more thing I noticed was, the use of VMargs which was previously posted was incorrect, hence 32 JVM was not used. On properly adding -d 32 to the VM Arguments found that running a 32 bit JVM was not supported on the platform.
The actual problem is, though this issue gets resolved by using a 32 bit JVM, it won't be possible to use it for the application.
So I wanted to know, other than using a 32 bit JVM or upgrading the libjuh.so to 64 bit, is there any possible alternative which might be helpful.
Please do reply for any suggestions.
Thanks,
Ajinkya

There isn't a way to launch a 32-bit Eclipse/SWT app, or to load 32-bit
libraries, with a JRE that's running in 64-bit mode. So I don't have
anything to suggest beyond getting a 32-bit JRE or re-compiling your
library as 64-bit.
