Hellu,
I did some more testing and discovered where the problem is. When I do return a return code of for example 400 or 500 I get the error listed below. If I set a return code 200 in my jsp it all works fine ... I did the same test with a asp page and got the same error. Hmmm strange... Can someone explain this ..... or this some kind of bug ?? The code in my main to test it all: ------------- BufferedWriter out = new BufferedWriter(new OutputStreamWriter(connection.getOutputStream())); out.write(sms,0,sms.length()); out.close(); BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); String inputLine; while ((inputLine = in.readLine()) != null) System.out.println(inputLine); in.close(); ------------- The JSP that is called: -------------- BufferedReader in = new BufferedReader(new InputStreamReader(request.getInputStream())); String inputLine = ""; String totLine = ""; while ((inputLine = in.readLine()) != null) { totLine = totLine + inputLine; } in.close(); // close input stream. System.out.println("Received: "+totLine); response.setContentType("text/html"); response.setStatus(400); out.println("bla"); ------------- En de error: -------------- java.io.FileNotFoundException: http://localhost:9000/groupsend/bla/receiveStrm.jsp at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at connect2Url.main(connect2Url.java:57) -------------- Please some help, Ed Bras ----- Original Message ----- From: "Eddie" <[EMAIL PROTECTED]> To: "Orion-Interest" <[EMAIL PROTECTED]> Sent: Wednesday, November 14, 2001 9:10 AM Subject: HTTP response help please ? > Hellu, > > Please some HTTP response help as it drives me grazy. > I have a tiny java program (originaly it is part of the EJB but I extrated > it to a stand-alone program for testing) that opens a Url connection and > sends something through a Stream.
