Sending from a Java Software to a email!

[edin94]

Hi

I have a problem sending this information

 
private void postFormToServer() throws Exception {
  String address = UtilityStore.WBW_SERVER;
        URL url = http://myadress.com/send_mail.php;
        URLConnection connection = url.openConnection();
        connection.setDoOutput(true);
        if(connection instanceof HttpURLConnection) {
         ((HttpURLConnection)connection).setRequestMethod("POST");
        }
        OutputStreamWriter streamWriter = new OutputStreamWriter(connection.getOutputStream());
        streamWriter.write(customerNameField + SEPARATOR + customerInfoField + SEPARATOR + emailField);
        streamWriter.close();
 }

to this page

<?php

$to = "my mail@gmail.com";
$emailField= $_POST["emailField"];
$subject= $_POST["subject"];
$customerNameField= $_POST["customerNameField"];
$customerInfoField= $_POST["customerInfoField"];

if (mail ($to, $subject, $customerInfoField ,"From: $customerNameField <$emailField>"))

echo nl2br("<h2>Sent!</h2> 
<b>mottagare:</b> $to
<b>ämne:</b> $subject
<b>meddelande:</b>
$customerInfoField
");

else
echo "No";

?>

Its just not sending the mail, but Im not getting any errors.
