Using platformRequest(url) to open RealPlayer doesn't work ? please help !

[lunatictr]

Hi all. I'm trying to open a RTSP stream using real player with my J2ME application. but I get the error
Cannot make a static reference to the non-static method platformRequest(String) at the line

MIDlet.platformRequest(url);

Can you please check my code ? what am I doing wrong ? what should I do to make this work ?
ps: I'm working on nokia e65, MIDP 2.0 CLDC 1.1

here's my code

//imports here

public class VideoCanvas extends Form implements CommandListener
{

	private Command start;
	private Command back;
	private Command exit;
	private Command rotateLeft;
	private Command rotateRight;
	private String url;

	VideoCanvas(String url)
	{
		super("MHSS");
		{
			start = new Command("Start",Command.OK,0);
			back = new Command("Back",Command.OK,0);
			exit = new Command("Exit",Command.BACK,0);
			rotateLeft = new Command("Turn Camera Left",Command.OK,0);
			rotateRight = new Command("Turn Camera Right",Command.OK,0);

			this.url = url;
			addCommand(start);
			addCommand(rotateLeft);
			addCommand(rotateRight);
			addCommand(back);
			addCommand(exit);
			setCommandListener(this);
		}
	}

	public void commandAction(Command c, Displayable arg1) {
		if(c == start)
		{
			try
			{
				MIDlet.platformRequest(url); //this is where I get the error ????
			}
			catch (Exception e)
			{
				e.printStackTrace();
			}
		}
		else if(c == exit) {
			Main.midlet.notifyDestroyed();
		}
		else if(c == back) {
			Main.mobileDisplay.setCurrent(Main.loginForm);
		}
		else if (c==rotateLeft)
		{
			RotateCamera rotateCameraObject = new RotateCamera("ROTATELEFT");
			Thread rotateCameraThread = new Thread(rotateCameraObject);
			rotateCameraThread.start();
		}
		else if (c==rotateRight)
		{
			RotateCamera rotateCameraObject = new RotateCamera("ROTATERIGHT");
			Thread rotateCameraThread = new Thread(rotateCameraObject);
			rotateCameraThread.start();
		}

	} 
}

Cannot make a static reference to the non-static method platformRequest(String)

platformRequest() is an instance method, not a class (static) method. You must invoke it with an instance of the class, not the class itself. You might want to check out your Java basics.

You cannot create instances of MIDlet. You must use the MIDlet object created by the application manager. This is the object "this" in the startApp() method of your MIDlet class.

Note that platformRequest() is only guaranteed to support protocols "http:" and "tel:". Other protocols might not be supported.

Thanks for you answer, I've corrected it. It works now.
Here's what I did.

Main MIDlet

public class Main extends MIDlet
{
	public static Main midlet;
        //other stuff
	public Main()
	{
		midlet=this;
                //other stuff
	}
        //MIDlet methods

	
	
}

And the videocanvas class

public class VideoCanvas extends Form implements CommandListener
{

	String url;
        //other stuff

	VideoCanvas(String url)
	{
		super("MHSS");
		{
			//constructor stuff
		}
	}

	public void commandAction(Command c, Displayable arg1) {
		if(c == start)
		{
			try {
				Main.midlet.platformRequest(url);
			} catch (ConnectionNotFoundException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		//other stuff

	} 
}
