Does the comm api come with doc on where to put the dlls and properties files? How did you follow those instructions?

Sorry I'm not familiar with Linux to know where to put the files. What does the comm api doc say?
Are you able to get the code to work in a standalone program (without the server) without the files being in the current directory? IE make the jvm find them in the correct system folders.
