Problem using http post over j2me

[Dushyant Chhetri]

Hi Guys,
I am trying to use j2me client to post data to a servlet using Post type.
Now the problem is that I am able to hit the servlets doPost method, However the data sent over to https request is not being captured and every time I am getting null.

What I am doing is

 try
    {
      http = (HttpConnection) Connector.open(url);
      oStrm = http.openOutputStream();
      http.setRequestMethod(HttpConnection.POST);
      http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
     // Write userid
      byte data[] = ("?username=admin").getBytes();
      oStrm.write(data);
      String o1= new String(data);
      // Write password
      data = ("&password=" + "admin").getBytes();
      oStrm.write(data);
      String o= new String(data);
      data=("submit=Login").getBytes();
      oStrm.write(data);
      System.out.println("Stream : "+url+o1+o);  

However I am getting no data on the server side.

If the problem manifests itself on the server side, wouldn't it make more sense to post that code?

It looks like there's a "&" missing in front of "submit", and what's the "?" doing in front of "username"? POST data is not an URL.

Hi..
try with this .....

   
public String sendPostRequest() {
        HttpConnection hc = null;
        DataInputStream dis = null;
        DataOutputStream dos = null;

        String message = "";
//        System.out.println(URL);
        // specifying the query string
        String requeststring = "request=gettimestamp";
        try {
            // openning up http connection with the web server
            // for both read and write access
            hc = (HttpConnection) Connector.open(URL, Connector.READ_WRITE);

            // setting the request method to POST
            hc.setRequestMethod(HttpConnection.POST);

            // obtaining output stream for sending query string
            dos = hc.openDataOutputStream();
            byte[] request_body = requeststring.getBytes();

            // sending query string to web server
            for (int i = 0; i < request_body.length; i++) {
                dos.writeByte(request_body[i]);
            }
            // flush outdos.flush();

            // obtaining input stream for receiving HTTP response
            dis = new DataInputStream(hc.openInputStream());

            // reading the response from web server character by character
            int ch;
            while ((ch = dis.read()) != -1) {
                message = message + (char) ch;
            }

        } catch (IOException ex) {
            ex.printStackTrace();
        } finally {
            // freeing up i/o streams and http connection
            try {
                if (hc != null) {
                    hc.close();
                }
            } catch (IOException ignored) {
            }
            try {
                if (dis != null) {
                    dis.close();
                }
            } catch (IOException ignored) {
            }
            try {
                if (dos != null) {
                    dos.close();
                }
            } catch (IOException ignored) {
            }
        }
        hc = null;
        dis = null;
        System.gc();
        
       
        return message;
    }
