System call with java 3

[mike_ledis]

Hallo i am trying to execute some programs through java. I want to execute the following programs gedit,firefox,gimp,nano and blackjack (i am using ubuntu linux o/s).

I managed to execute all the programs except blackjack.
I am using the command
Runtime.getRuntime().exec();
when i give as input to the command the full directory of the blackjack(usr/games/blackjack) it does not work.

Any suggestions?

Maybe it requires a root user or the administrator privilege. Did you check on it?
