ABAIXO UM EXEMPLO:

Fonte: <MIDP>\api\javax\microedition\io\HttpConnection.html

 

Example using POST with HttpConnection

Post a request with some headers and content to the server and process the headers and content.

Connector.open is used to open url and a HttpConnection is returned. The request method is set to POST and request headers set. A simple command is written and flushed. The HTTP headers are read and processed. If the length is available, it is used to read the data in bulk. From the HttpConnection the InputStream is opened. It is used to read every character until end of file (-1). If an exception is thrown the connection and stream is closed. 

    void postViaHttpConnection(String url) throws IOException {
        HttpConnection c = null;
        InputStream is = null;
        OutputStream os = null;

        try {
            c = (HttpConnection)Connector.open(url);

            // Set the request method and headers
            c.setRequestMethod(HttpConnection.POST);
            c.setRequestProperty("If-Modified-Since",
                "29 Oct 1999 19:43:31 GMT");
            c.setRequestProperty("User-Agent",
                "Profile/MIDP-1.0 Configuration/CLDC-1.0");
            c.setRequestProperty("Content-Language", "en-US");

            // Getting the output stream may flush the headers
            os = c.openOutputStream();
            os.write("LIST games\n".getBytes());
            os.flush();                // Optional, openInputStream will flush

            // Opening the InputStream will open the connection
            // and read the HTTP headers. They are stored until
            // requested.
            is = c.openInputStream();

            // Get the ContentType
            String type = c.getType();
            processType(type);

            // Get the length and process the data
            int len = (int)c.getLength();
            if (len > 0) {
                byte[] data = "new" byte[len];
                int actual = is.read(data);
                process(data);
            } else {
                int ch;
                while ((ch = is.read()) != -1) {
                    process((byte)ch);
                }
            }
        } finally {
            if (is != null)
                is.close();
            if (os != null)
                os.close();
            if (c != null)
                c.close();
        }
    }
