Getting IO exception when running Linux command in Java -

i'm writing java app in windows connect linux machine through ssh. i'm getting following exception:

java.io.ioexception: cannot run program ssh: createprocess error=2, cannot find specified file. 

code:

process p = runtime.getruntime().exec("ssh root@xxx.xxx.xxx.xxx ls"); 

while running command in cmd working, not through java. ssh in path environmental vars.

you need interpreter understand ssh command:

process p = runtime.getruntime().exec(new string[]{"cmd", "ssh root@xxx.xxx.xxx.xxx ls"});
