Anup did you find a solution to this? I am running into similar issues please let me know. I would appreciate your help.

It is unlikely that Anup will answer after over four years. You would have been better off just 
asking your question in the newsgroup.

You can use JNI, but why should Java know if a user has admin privileges? That is system-specific, 
and not really Java's job.

Even if a user has admin privileges, the program might be restricted from performing certain actions.

The usual means is to try what you need to do and catch exceptions. Warn the user if they're running 
the program with insufficient privilege or whatever.

You could also RTFM for API calls that might help you.

This might, for example, turn up 
http://docs.oracle.com/javase/7/docs/api/java/lang/Runtime.html#exec(java.lang.String)
and related calls that would let you call out to the system to determine rights.

Do you know how to determine the user's rights with OS-specific utilities?

Again, next time just start a new thread. Years-old threads aren't likely to be much help.

Java's scheme for handling this sort of thing is called Permissions.
You can ask "Do I have permission to do this specific thing e.g. write
this file"  Or you can try to do it and get an exception.  You might
be able to use this rather than knowing the Unix status.
If you need the Unix status, that is platform specific and can't very
well be part of Java.  You would need JNI to access it.
