Re: [Java-player-users] Javaclient2 example code not working?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

The latest SVN version of Javaclient bundled with Player 2.0.5 should work. To make Javaclient work with Player 2.1.x, 
several changes will have to be made, including the support for dynamic arrays.

Cheers,
Radu.
