Hi,



thanks
for your reply,

I want to solve a NLP and use that's results in a Java
project so I use Jipopt, I followed this steps:

create
a Java project using eclipse

add
Jipopt.jar file to that

create
a “lib” folder and copy the DLL file there

but
when I run that (as a Java application) see this error:

Exception
in thread "main" java.lang.UnsatisfiedLinkError:
/home/m12345/workspace_2jiopot/jipopt2/lib/libjipopt.so:
/home/m12345/workspace_2jiopot/jipopt2/lib/libjipopt.so: wrong ELF
class: ELFCLASS32 (Possible cause: architecture word width mismatch)

my
OS is ubuntu Linux 12.10 (64bit), is my OS version because of this
error?

Can
I use that DLL file? Do I have to compile the C++ source code? 


Please
guide me, Thanks for your time.
