I wanted to access device so i have developed one Java code in eclipse using JNI library which calls c code for communicating with device.

For accessing device we require sudo authentication in eclipse so i have done that authentication using the following link

How do I run my application as superuser from Eclipse?

But right now i am facing the problem in loading JNI libraries in Java code

I am getting error

Don't use sudo for this task! Instead, give the appropriate permissions to the device so that the user can access it. This is possible by either using chmod/chown to change the device file's permissions, or use adduser <username> <group> to add the current user to that devices group.
