WiimoteWhiteboard doesn't start

[fdelente]

Hello.

I'm trying to use WiimoteWhiteboard (http://www.uweschmidt.org/wiimote-
whiteboard) on my linux laptop.

I already tried my bluetooth stack with cwiid, so I know it works.

I have copied bluecove-2.0.3.jar and bluecove-gpl-2.0.3.jar in the
WiimoteWhiteboard/ directory; I then start the application with

java -classpath bluecove-2.0.3.jar:bluecove-gpl-2.0.3.jar -jar
WiimoteWhiteboard.jar

but everytime I get

java.lang.IllegalStateException: Bluetooth failed to initialize. There
is probably a problem with your local Bluetooth stack or API.

I'm the author of the Java WiimoteWhiteboard. Since you also posted
about this error on my website, I naturally went to look for help here
and directly found this thread.
I can't tell you why it doesn't work, but I can probably add some
valuable information for anyone who is willing to help, i.e. Vlad :)

Do you fulfill all the requirements mentioned at http://bluecove.org/bluecove-gpl
?

The reason why I said to add the bluecove-gpl library to the "/lib"-
folder my WiimoteWhiteboard.jar is that I use One-JAR (http://one-
jar.sourceforge.net/) to package the application. One-JAR's
classloader apparently ignores the "-classpath" option at the command
line, but loads all libraries of the folder "/lib" inside the main JAR
file (WiimoteWhiteboard.jar in this case).
Hence, after adding the bluecove-gpl library to WiimoteWhiteboard.jar,
it is sufficient to start my app with "java -jar
WiimoteWhiteboard.jar". You also don't need to add the bluecove-2.0.3
snapshot to WiimoteWhiteboard.jar, since it's already in there.

Just for Vlad, you wrote on my website: "I'm on linux SlAMD64 12.1, I
have Java 1.6 installed."
