Urgent - POST http form

Question

Hello,
I am trying to upload a file and two string values by using this form.
<form method="post" enctype="multipart/form-data" action="./servlet/upload_media">
<td> <input type=file size=20 name="fname" > </td>
<td> <input type="hidden" name="pocketID" value="5326531"> </td>
<td> <input type="hidden" name= "username" value="something"> </td>
<td> <input type=Submit value=Upload> </td> </form>
The code i'm using to upload
public void UploadImage(byte[] image)
        HttpConnection httpConn = null;
        InputStream is = null;
        OutputStream os = null;
        try
            HttpConnection c = (HttpConnection) Connector.open(url);
            c.setRequestMethod(HttpConnection.POST);
            String message1 =  "--BbC04y"+"\n"+
                             "Content-Disposition: file; filename = \"0x0.png\" \n"+
                             "Content-Type: image/png;  \n"+
                             "Content-Transfer-Encoding: binary\n\n";
            String message2= "\n--BbC04y"+"\n"
                             + "Content-Disposition: form-data; name=\"pocketID\"; value=\"130\" \n"
                             + "Content-Disposition: form-data; name=\"username\"; value=\"dikaios\"  \n";
             byte[] Message1 = message1.getBytes();
             byte[] Message2 = message2.getBytes();
             int length = Message1.length + Message2.length + image.length;
             c.setRequestProperty("User-Agent", "Profile/MIDP-2.0 Confirguration/CLDC-1.1");
             c.setRequestProperty("Content-Length:",Integer.toString(length));
             c.setRequestProperty("content-type", "multipart/form-data; boundary=AaB02x");
             DataOutputStream dos = new DataOutputStream(c.openOutputStream());
             for(int i=0; i < Message1.length; i++)
                    dos.writeByte(Message1);
for(int i = 0 ; i < image.length ; i++)
dos.writeByte(image[i]);
for(int i=0; i < Message2.length; i++)
dos.writeByte(Message2[i]);
The problem is that I get this error message
java.io.IOException: error 32 during TCP write
     at com.sun.midp.io.j2me.socket.Protocol.writeBytes(+7)
     at com.sun.midp.io.BaseOutputStream.write(+49)

     at com.sun.midp.main.Main.main(+116)
The problem appears when I try to put the picture in the data output stream. It is the first time I do this, if I am doing something wrong when I constuct the form please let me know.

You can do it from anywhwere in the pipeline. You can use an assign action and modify the content of $body. Don't modify the whole variable.
If it still does not work, here is what I would do. Write a simple html file containing a submit and point to a service bus dummy proxy service. Inside the dummy service use a log action to log the content of $body so you have an idea how it should exactlty looks like.
