Send and receive data between Arduino and Processing

Hi, my goal is simple but there's something wrong in my codes.

Processing has to send 1 to Arduino and it has to answer with a 190.

Arduino: http://pastebin.com/QLxWHtZv
Processing: http://pastebin.com/kzfPQDLg

Running those codes arduino receive 1 but Processing doesn't receive 190

try to change this in your sketch:

Serial.write(190);

to this:

Serial.println(190);

added: unless you expect to receive a byte...

Nothing...

Found the solution (workaround?):
in the processing sketch I just replaced:

delay(1000);

with

delay(3000);
