Run ssh commande by java to launch script in ec2 instance

Question

I have a script in amazon machine and i would run this script using ssh from netbeans. i use this code :

String myKey="/home/local/my_key.pem";
Runtime runtime = Runtime.getRuntime();
String commande = "ssh -i "+myKey+" [email protected] 'bash runFile.bash' -o StrictHostKeyChecking=no ";

Process p = runtime.exec(commande);
p.waitFor();

But it does not work. When i print p.getErrorStream() I obtain:

bash: writeFile.bash: command not found

When i run the commande from bash it works but in netbeans no !

Someone can explain me why ? other solution please ?

Thanks

What do you get? an error message? can you add it to the question? — Uri Agassi

No error, just the command line does not make what it should do ! — Mehdi

what is returned? you can also read p's getOutputStream() and getErrorStream() to see if you can see what the problems may be — Uri Agassi

What is writeFile.bash? is it a file you are trying to execute? is it where it is supposed to be? is it executable? try executing ./writeFile.bash — Uri Agassi

Try this:

String myKey="/home/local/my_key.pem";
Runtime runtime = Runtime.getRuntime();
String commande = "ssh -i "+myKey+" [email protected] 'bash ./runFile.bash' -o StrictHostKeyChecking=no ";

Process p = runtime.exec(commande);
p.waitFor();

(use bash ./runFile.bash instead of bash runFile.bash)
