Guide for J2ME PP to use RMI and Bluetooth

Question

hi
i have a current project its about an Ordering System, and i was thinking of using ppc as an order client
before i want to get on with this i was just wondering if i can get some help from here.
i just want to ask would it be any problem if i use J2SE to write a server to communicate with the ppc using rmi methology and bluetooth as network device (USB bluetooth for PC). can some one please give me some direction of how to do it, or maybe there's a beta way to do something like this?
do i just write the code as how you would normally write for rmi application for PC?
do i need to use third party driver for bluetooth (PC and PPC)?
btw my PPC is HP Pocket PC 2003 running Window CE and use J9 JVM
thank you for in advance as i would really appreciate and so is others :)

Hi,
I have the same message "Error: Unable to query value..."
But I can't read from serial port com8. I need to read data from gps, but first I want to read anything from com8.
My application looks like that:
import java.util.*;
import javax.comm.*;
import java.io.*;
public class Porty {
static CommPortIdentifier portId,tym;
static Enumeration portList;
private InputStream cos;
private SerialPort porty;
public Porty(){
     CommPortIdentifier portID = null;
     for (Enumeration portList = CommPortIdentifier.getPortIdentifiers();
          portList.hasMoreElements() ;) {
     CommPortIdentifier portId = (CommPortIdentifier)portList.nextElement();
     if (portId.getName().equals("COM8:")) {
          tym = portId;
     if (tym == null) {
     // Unable to find COM8
          System.out.println("No Com8");
     return;
     else {
     // found COM8
          System.out.println("Yes!!! Com8");
     try{
          cos = porty.getInputStream();
     }catch (IOException e){}
     System.out.println("Data from Com8");
     System.out.println(cos);
public static void main(String[] args){
     Porty porcik = new Porty();
What is wrog. Could samebody help me !!! What I suppouse to do !!! Could You send me same application, which is working and it reads from port.
Thank You...
