Establishing serial port connections through J2ME

Question

Respected Friends,
I wanted to establish a connection with the serial port through my J2ME application.I am writting the following code it compiles(build) successfully but it is throwing exception which means that the Sun's J2ME wireless toolkit does'nt supports serial port connection,can any one please tell me the reason why the toolkit is not supporting serial port and if there is any mistake in the code what is it,I am using J2ME Wireless toolkit 1.0(Version 1.0) the code is as follows:
import javax.microedition.lcdui.*;
import javax.microedition.io.*;
import javax.microedition.midlet.*;
import java.io.*;
public class TestSerial extends MIDlet implements CommandListener
Form form1;
TextField tf1;
Display disp1=null;
Command command1;
StreamConnection sc;
OutputConnection oc;
Connection connection1;
/****************************DefiningConstructor*****************************/
public TestSerial()
disp1=Display.getDisplay(this);
command1=new Command("Start",Command.OK,1);
form1=new Form("Serial Port Connection");
form1.addCommand(command1);
form1.setCommandListener(this);
public void startApp()
disp1.setCurrent(form1);
public void pauseApp()
public void destroyApp(boolean b)
public void commandAction(Command c,Displayable d)
if(c==command1)
try
/************Establishing serial port connection****************/
connection1= Connector.open("comm:0;baudrate=9600");
connection1.close();
catch(Exception e)
System.out.println(e.toString());
}Please mail your precious suggestions regarding this problem as soon as possible.
Thanking You,

I am not sure about sun wireless toolkit 1.0,
check the settings, -> permissions... (We have this in sun wireless toolkit 2.3, where i can set the security options)
Hope it helps...
