Running external program within java produces different results from terminal command

Question

Hey I'm trying to run a command within java :

String curlCommand=String.format("curl --max-time %d --socks5 %s -A \"%s\"  -i %s",maxWait,proxy ,getAgent(), myurl);
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(curlCommand);

For some reason executing this line would result in cookies to be denied.

however, when I run the curl program from terminal I have no problem and everything works as it should be

here is the result if I run the program Java

So My question is why should it be different at all, am I missing something out here?

Answer 1

Alright I finally solved it.

the reason is Runtime runtime = Runtime.getRuntime();

it should not be used. as it just messes up with the parameters (eventhough the print out of the command looks fine, it just didn't send the right command to the OS) instead I should have used ProcessBuilder class . it worked like a charm.
