read string sent from java from serial port in arduino

hi, i'm trying send string code in java. know works cause monitorized virtual serial port , says writes bytes send. use port com5 1 im using in arduino.

code: [select]

import java.io.*;
import java.util.*;
import gnu.io.*;

public class simplewrite {
    static enumeration portlist;
    static commportidentifier portid;
    static string messagestring = "color ff00ffend";
    static serialport serialport;
    static outputstream outputstream;

    public static void main(string[] args) {
        portlist = commportidentifier.getportidentifiers();


        while (portlist.hasmoreelements()) {

            portid = (commportidentifier) portlist.nextelement();
            if (portid.getporttype() == commportidentifier.port_serial) {

                 if (portid.getname().equals("com5")) {

                    try {
                        serialport = (serialport)
                            portid.open("simplewriteapp", 2000);
                    } catch (portinuseexception e) {system.out.println("err");}
                    try {
                        serialport.setserialportparams(9600,
                            serialport.databits_8,
                            serialport.stopbits_1,
                            serialport.parity_none);

serialport.setflowcontrolmode(
        serialport.flowcontrol_none);

                    } catch (unsupportedcommoperationexception e) {system.out.println("err2");}
                    try {
                        outputstream = serialport.getoutputstream();
                    } catch (ioexception e) {system.out.println("err1");}

                    try {
                        outputstream.write(messagestring.getbytes());
system.out.println(messagestring);

//outputstream.close();
//serialport.close();

                    } catch (ioexception e) {system.out.println("err3");}
                }
            }
        }
    }
}


the code in arduino this. try print see if works , receiving correctly, doesn't enter in if because doesn't detect data received (sorry english, hope understandable).
i put delay can see com monitor in arduino in time, because have have closed while run java app.

code: [select]

void setup() {     
  rb.init(); 
  // initialize digital pin output.
  serial.begin(9600); 
}

// loop routine runs on , on again forever:
void loop() {
    while (true)
    {
      if (serial.available() > 0) {
          serial.readbytes(inputbuffer, serial.available());
          delay(15000);
          serial.print("i got ->");
          serial.print(inputbuffer);
          serial.println("<-");
       }
   }
}


hope can cause i'm stuck in this. thank you

please post code.
all of it.
