PrintWriter does not send correct text over HTTP

Question

Hello All,
I need information to resolve a problem I am having with PrintWriter and sending text using HTTP.
I am developing a client/server system. A client will be used to connect to a Tini (a Dallas Semiconductor designed embedded system). Currently, to understand HTTP operation, I wrote a server that resides on the tini that listens for a connection attempt and when one is made prints the HTTP message in Dallas' JavaKit application window. The resultant Tini display includes some hardcoded tini text (italics only in (b) and (c) below) along with that received from the client app (italic bold in (b) and (c) below).
I have also written some test client side code (see (a) below) in Sun's Java Studio Creator that sends a couple of lines of text so that I could see what my client app would actually send. I tried a few different ways of creating a PrintWriter object as shown in the code at (a) below just to see if it was a character set problem.
The problem is that I get two different results under the following conditions:
[Condition 1]: Entering "HTTP://tini" in the browser and pressing Enter. See result (b) below. This is correct and shows what the browser sends to the tini. The tini outputs the text immediately after pressing Enter.
[Condition 2]: Running my client code in the browser. See result (c) below. This is incorrect and sends just a bunch of "y"s with umlauts as the message. The tini immediately outputs text up to the "cnt=0" line and then can take up to a couple of minutes to complete the message.
1. Can anyone tell me why the client sends those "�" instead of the strings I encoded for all character sets?
2. Why does the client code takes so long to complete after the initial transmission?
3. Can anyone provide me with links to information that explains this behavior? I searched Sun and the forum but found nothing.
(a) Here is the current test client side code that sends a couple of strings to the tini:
    public String button3_action() {
        // TODO This should send the tini a request for its IP address
        String protocol = "HTTP";
        String host = "tini";
        try{
             URL tiniURL = new URL("http://tini");
             URLConnection tiniConnection = tiniURL.openConnection();
             tiniConnection.setDoOutput(true);
     //     Comment out one then the other to see if there is a difference in result (there is not!)
     //        PrintWriter tiniout =  new PrintWriter(new OutputStreamWriter(tiniConnection.getOutputStream(), "UTF-16"));
     //        PrintWriter tiniout =  new PrintWriter(new OutputStreamWriter(tiniConnection.getOutputStream(), "UTF-8"));
     //        PrintWriter tiniout =  new PrintWriter(new OutputStreamWriter(tiniConnection.getOutputStream(), "ISO-8859-1"));
     //        PrintWriter tiniout =  new PrintWriter(tiniConnection.getOutputStream());
             PrintWriter tiniout =  new PrintWriter(new OutputStreamWriter(tiniConnection.getOutputStream()));
             tiniout.println("GET / HTTP / 1.1\r\n");
             tiniout.flush();
             tiniout.println("IPaddress?");
             tiniout.flush();
             tiniout.close();
        catch(MalformedURLException e){
            e.printStackTrace();
        catch(IOException e){
            e.printStackTrace();
        return null;
(b) Result displayed in JavaKit from Condition 1:

Answer 1

This is to anyone that is having trouble sending data via a stream using a browser client. I found the answer after many different searches on the Sun site in a bug report: Bug ID: 4192018.
The problem arises from the way the API actually uses outputstreams. It appears that you must add an InputStreamReader to actually flush the OutputStreamWriter buffer. After reading this bug report I added
(tiniConnection.getOutputStream(), "ISO-8859-1"));
        OutputStreamWriter tiniout =  new OutputStreamWriter(tiniConnection.getOutputStream(), "ISO-8859-1");
        InputStreamReader tiniIn =  new InputStreamReader(tiniConnection.getInputStream(), "ISO-8859-1");
        tiniout.write("GET/HTTP/1.1\r\n");
        tiniout.flush();
        //This is necessary to actually send data.
        tiniIn.read();
        tiniout.write("IPaddress?");
        tiniout.flush();
        //This is necessary to actually send data.
        tiniIn.read();
        tiniout.close();
        catch (MalformedURLException e){
            e.printStackTrace();
        catch (IOException e){
            e.printStackTrace();
        }NOTE: The preliminary program still does not perform correctly but it does send data that is displayed in tini's JavaKit window. At least I can continue to verify how the browser sends data.
I hope this helps someone.
