nah. first, he said that the endpoint wants GET params, and you are
opening with POST method below. you don't need to write data to the
stream. the data is passed to the endpoint as GET params.
if you just want to pass the get params, it's enough to just call
openConnection(). depending on how the endpoint returns a response, you
can check the response code with getResponseCode(), or you can read a
data response (XML, JSON, etc) by calling getInputStream(). here's the
simplest case,
URL url = "" URL(urlString);
HttpURLConnection uc = (HttpURLConnection)
url.openConnection();
uc.setReadTimeout(30 * 1000); // 30 seconds
if (uc.getResponseCode() != 200) {
//TODO: handle error and return
}
reader = new BufferedReader(new
InputStreamReader(uc.getInputStream(), "ISO-8859-1"), 8192);
while ((line = reader.readLine()) != null) {
result.append(line);
result.append('\n');
}
// result data is in "result"

It's through GET parameters. I can type in the following command in a

I'm used to sending commands through TCP sockets so I'm sure what's
the best way to send a URL command. I'm guessing the "opening" a URL
part isn't adequate.
