Here, you find a fork for my personnal contribution to Barry project.

First, you have to install Barry from this fork repository (you can add GUI and OpenSync feature) :
$ cd /usr/local/src
$ git clone git://repo.or.cz/barry/progweb.git barry
$ cd barry
$ ./buildgen.sh
$ ./configure
$ make
$ make install

Now, go into your work directory where are your ".debug" files. You can also copy your ".debug" files generated by RIM's JDE in your current path :
$ cd ~
$ mkdir Project
$ cp <.debug files> .
$ bjdwp localhost 8000

Then, from a JDB client :
$ jdb -connect com.sun.jdi.SocketAttach:hostname=localhost,port=8000
