Send file to a remote server

Question

how do I send a file to a remote server?
I attached my code so you can see what is missing.
the purpose of it is to send a server all the files in a directory + the name of directory + how many files there are
URL url=null;
                try {
     url= new URL("www.<server's address>");
                 }catch (MalformedURLException e) {
                  try {
      // Construct data
        File[] picFiles= path.listFiles(new pictureFileFilter());
        int numOfFiles= picFiles.length;
        String setName= path.getName();
        String data= ("setName= " + setName);
        data += ("&" + "numOfFiles= " + numOfFiles);
       String[] allFiles= new String[numOfFiles];
       for (int i=0; i<numOfFiles; i++) {
             FileInputStream FIS= new FileInputStream(path);
          //WHAT TO DO HERE?!?!?
     data += ("&"+"allFiles="+allFiles);          
        // Send data
                   URLConnection conn = url.openConnection();
                  conn.setDoOutput(true);
                  conn.setDoInput(true);
                  OutputStreamWriter wr = new 
                                             OutputStreamWriterconn.getOutputStream());
                  wr.write(data);
                  wr.flush();
        // Get the response
                    BufferedReader rd = new BufferedReader(new       
                                            InputStreamReader(conn.getInputStream()));
                   String line;
                    while ((line = rd.readLine()) != null) {
                                //what to do with response (this part is OK)
                 new GoodBadMassage(line);
                     wr.close();
     rd.close();
         } catch (Exception e) {
         }~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
another thing-
is the line --- conn.setRequestProperty("content-type","binary/data");
replace the need in ---
String data= ("setName= " + setName);
OutputStreamWriter wr = new utputStreamWriter..
wr.write(data);
I'm not sure what does is do (setRequestProperty)
THANKS!!

You start out by trying to use a malformed URL (it doesn't start with a protocol). This suggests to me that you haven't thought about the natural question: what kind of server software is running on that server that will accept files?
