Help-- Do I need a domain name or IP is enough ?

Question

Hi Everyone,
I had posted earlier regarding my application that it doesnt work on a real device but works on every manufacturers emulator !
I have got ADSL and I m using my IP address to access my Tomcat server and I m passing parameters in the URL :
http://xxx.xxx.xxx.xxx/servlet?param1&param2&param3&param4
I havent specified anything in my application like GET or POST just passing values in URL.
So, do I need to have a specifc domain name since I m not using GET or POST ?
Please guide.
Thank you.

Here is the code...
//This is the WaitScreen from where I m making a function call to get image
if (simpleCancellableTask1 == null) {                      
        // Insert pre-init code here
             simpleCancellableTask1 = new org.netbeans.microedition.util.SimpleCancellableTask();                       
             simpleCancellableTask1.setExecutable(new org.netbeans.microedition.util.Executable() {
                 public void execute() throws Exception {
                     im=getImage(url);
                     get_Image1Form().append(im);
         return simpleCancellableTask1;
//Code for making connection and getting image
private Image getImage(String url) throws IOException
      int width=mainForm.getWidth();
      int height=mainForm.getHeight();
     String serverUrl="http://localhost:8080/imageservlet";
     String httpUrl=serverUrl +"?width=" +width + "&height="+height + "&from="+from+"&to="+to;
     ContentConnection connection= (ContentConnection) Connector.open(httpUrl);
     DataInputStream iStrm = connection.openDataInputStream();
      ByteArrayOutputStream bStrm = new ByteArrayOutputStream();
     int firstfile,secondfile;
     byte imageData[] = null;
     byte imageData2[]=null;
     try
         int length =(int) connection.getLength();
         firstfile=iStrm.readInt();
         imageData=new byte[firstfile];
         iStrm.readFully(imageData);
         secondfile=iStrm.readInt();
         imageData2=new byte[secondfile];
         iStrm.readFully(imageData2);
     }catch(Exception ex)
         System.out.println("here is "+ex.getMessage());
         showAlert(ex.getMessage());
     }finally
         if(iStrm !=null)
             iStrm.close();
             bStrm.close();
         if(connection !=null)
             connection.close();
     img=Image.createImage(imageData,0,imageData.length);
    img1 =Image.createImage(imageData2,0,imageData2.length);
     return img;
}  So please tell me if there is anything wrong in here...
Thank you
