Hi, im real new to this and have no clue what im doing. I have a java file that does a real simple tic tac toe game with a server. I have to figure out how to install this program on my BB 8330. I was wondering if someone could give me some pointers or steps on what i have to do. The code was written as a Midlet i think and is supposed to be a general java phone app. Just not sure how to install it on my phone. Here is the code in the java file:

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.io.*;
import java.io.*;
import java.util.*;

interface Constants
{
	public static final int CONDITION_WIN 	=	255;
	public static final int CONDITION_LOST =	254;
	public static final int CONDITION_DRAW	=	253;
}

class TicTacCanvas extends Canvas implements Constants
{
	private TicTacClient app_;

	public TicTacCanvas(TicTacClient app)
	{
		app_ = app;
	}

	public void paint(Graphics g)
	{
		int linesx, linesy, lineex, lineey;
		int circlecx, circlecy, circler;

		g.setColor(255, 255, 255);
		g.fillRect(0, 0, getWidth(), getHeight());
		g.setColor(0, 0, 0);

		//g.drawString("Hello World!", 0, 0, Graphics.LEFT | Graphics.TOP);

		int i, j, contents;
		int skipX, skipY;

		g.setColor(0, 0, 0);

		//Draw lines of tic tac toe board
		skipX = getWidth() / 3;
		skipY = getHeight() / 3;

		//Draw game board lines
		for (i = 1; i < 3; i++)
		{
			linesx = i * skipX;

				lineex = getWidth();
				lineey = j * skipY;

				g.drawLine(linesx, linesy, lineex, lineey);
			}
		}

		//Draw Xes and Os
		for (i = 0; i < 3; i++)
		{
			for (j = 0; j < 3; j++)
			{
				contents = app_.gameBoard[(j * 3) + i];

				if (contents == 1)
				{
					//Draw blue X
					g.setColor(0, 0, 255);

					linesx = (i * skipX) + 2;
					linesy = (j * skipY) + 2;

					lineex = ((i + 1) * skipX) - 2;
					lineey = ((j + 1) * skipY) - 2;

					g.drawLine(linesx, linesy, lineex, lineey);

					linesx = ((i + 1) * skipX) - 2;
					linesy = (j * skipY) + 2;

					lineex = (i * skipX) + 2;
					lineey = ((j + 1) * skipY) - 2;

					g.drawLine(linesx, linesy, lineex, lineey);
				}
				else if (contents == 2)
				{
					//Draw red O
					g.setColor(255, 0, 0);

					circlecx = (i * skipX) + (skipX / 2) + 1;
					circlecy = (j * skipY) + (skipY / 2);

					if (skipX < skipY)
						circler = skipX / 2;
					else
						circler = skipY / 2;

					circler -= 3;

					//note the ridiculous gymnastics we have to do to draw a simple circle
					g.drawArc(circlecx - (circler), circlecy - (circler), circler * 2, circler * 2, 0, 360);
				}
			}
		}
