[Fouad Fares]

Hello,

I'm trying to send HTTP request to an sms provoder.
This request contains arabic text. The result of this arabic text is rubbish text.

Could you please advise me how can i set the unicode on my java request.
NB : I'm developping this program under Oracle Jdeveloper JDK 2 version 1.3

HttpURLConnection connection = (HttpURLConnection)csoftURL.openConnection();

String postBody = "Username=" + URLEncoder.encode(SMSID) + "&" +

"Message=" + URLEncoder.encode(s_return) + "&" +
"ReplyTo=" + URLEncoder.encode(SMSREPLYTO) + "&" +
"ResponseFormat=1";

connection.setRequestMethod("POST");
connection.setRequestProperty("content-type","utf-8");

// poster les param�tres
connection.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(connection.getOutputStream());
wr.write(postBody);
wr.flush();
wr.close();

// Avoir les r�sultats
connection.connect(); // throws IOException
int responseCode = connection.getResponseCode(); // 200, 404, etc
String responseMsg = connection.getResponseMessage(); // OK, Forbidden, etc

BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));

String oneline = "NULL";
div.WriteLog("debut SMS ");
while ( (oneline = br.readLine()) != null) {
WriteLog(oneline);
if (oneline.toUpperCase().indexOf("ACCEPTED") > 0)
{
InsertLog
}
}
