wrong ELF class: ELFCLASS64 (Possible cause: architecture word widthmismatch)

I compiled my jMultidev.jar and libhwAPI_64.so with 64bit.
How to debug this error?
$ java -jar jMultidev.jar

You cannot compile java sources for 64bit.
They are independent of 32 or 64bit.

Try
java -d64 -jar jMultidev.jar
to force the use of the 64bit JVM.

I've no experience with a shared object in java, but from the error
mesage I would say, that
the JVM is running in 32 bit mode and your lib is 64 bit.

$ java -d64 -jar jMultidev.jar
Failed to load function 'CA_GetHAStatus'.

However, the same source code works on a 64 bit linux computer (Linux
2.6.9-67.EL #1 Wed Nov 7 13:43:31 EST 2007 x86_64 x86_64 x86_64 GNU/
Linux).
java -d64 -jar jMultidev.jar
java -jar jMultidev.jar

Because java is write once, run everywhere, so I copy the jar files
from the linux computer to the solaris computer.
However,
java -d64 -jar jMultidev.jar
java -jar jMultidev.jar
both fails.

What is the problem?
Is it in libhwAPI_64.so?

How do you get the Interface to the libhwAPI_64.so library?. Is it
over JNI?
I have not done such a thing, but perhaps there is a problem in the
generated interface's calling the
Shared Object methods?
