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

[Jing T. <jin...@gm...>]

Dear all,

I was just trying to get the example code from the website working. But I
found the method call
robot.requestInterfaceSonar(0,PlayerConstants.PLAYER_OPEN_MODE); returns
null.

I'm on player/stage 2.1.0 and I've tried both Javaclient2.0.1 and the svn
version. I was simply running the
example "space wanderer". There're also some warnings after I run "player
simple.cfg" as follows.

I was just wondering if it's worth trying maybe an older version of p/s or
the svn version of javaclient2?

Thanks so much for you help in advance.

Cheers,

Jing
