Jcreater+MotoJ2SDK的配置与使用心得 传

答案：欢迎讨论 dd747@163.net

假设安装路径如下：
JCreator D:\Program Files\Xinox Software\JCreator LE
motoj2sdk D:\Motoj2sdk
JDK D:\jdk1.3.1

注意：要先击活模拟环境，运行D:\MotoJ2SDK\generic\scripts\runConstructor.bat
选择手机型号，选择语言，选择normal， 再"创建"。

启动Jcreater之后我的配置如下：
第一步 选择 Configure->Options->JDK Profiles
注意：一定新建 profile and select “D:\jdk1.3.1”
将名字改为“J2ME 388”
Add classes path “D:\Motoj2sdk\lib”
Add documentation path “D:\Motoj2sdk\docs”
分别将后加的两行移到最上方.

第二步 选择 Configure->Options->JDK Tools
选择Complier
选中 <Default> and edit it.
将 parameters 变为 -classpath D:/motoj2sdk/lib $[JavaFiles]

第三步 
选择 Configure->Options->Tools
点击“New”选择 DOS command 
名字为“Preverifier”
将 arguments 换为 d:\Motoj2sdk\bin\preverifier.exe -classpath "d:\Motoj2sdk\lib" -d . .
将 initial directory 变为 “$[PrjDir]”


第4步

按上面的方法在New一个 DOS command 
名字：“Run Emulator”
将 arguments 换成 “java -Djava.library.path=d:/MotoJ2SDK/lib -classpath "d:/MotoJ2SDK/bin/Emulator.jar";"d:/MotoJ2SDK/ConfigTool.jar" com.mot.tools.j2me.emulator.Emulator -classpath$[PrjDir];"d:/MotoJ2SDK/lib" -deviceFile d:/MotoJ2SDK/bin/resources/device.props javax.microedition.midlet.AppManager $[CurClass] -JSA 1 1”
将 initial directory 换成 “d:\Motoj2sdk\bin”

ok!编辑工具配置完毕！

新建一个工程——选择Empty Project
再取一个名字 比如：test
则jcreater自动在你的工作目录中生成目录test
再new一个file选择java File
写好你的原代码，保存 如：test.java
在Project中 选add file
然后选中你刚才的test.java

注意：不要有package ; 

编译——》tools中的Preverifier进行预先审核——》tools中的Run Emulator进行模拟

test.java 的例子：功能是捕捉键盘输入的ascII吗。

import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;


public class test extends MIDlet implements CommandListener {

/**
* The screen for this MIDlet
*/
private KeyEventsDemoCanvas myCanvas;

/**
* Reference to current Display
*/
private Display myDisplay;

/**
* Command to make sure soft key is not a key event
*/
private Command okCommand = new Command("OK", Command.OK, 1);

test() {

myDisplay = Display.getDisplay(this);
myCanvas = new KeyEventsDemoCanvas();
myCanvas.addCommand(okCommand);
myCanvas.setCommandListener(this);
}

/**
* Do nothing if a command is fired
*/
public void commandAction(Command c, Displayable s) {
}

/**
* Start the MIDlet
*/
protected void startApp() throws MIDletStateChangeException {

myDisplay.setCurrent(myCanvas);
}

/**
* Pause the MIDlet
*/
protected void pauseApp() {
}

/**
* Called by the framework before the application is unloaded
*/
protected void destroyApp(boolean unconditional) {
}

/**
* The screen for this application
*/
class KeyEventsDemoCanvas extends Canvas {

/**
* Background color (i.e. the color of the screen)
*/
public final int BACKGROUND_COLOR = 0xFFFFFF; // white

/**
* Foreground color (i.e. the color of the rectangles)
*/
public final int FOREGROUND_COLOR = 0x000000; // black

/**
* Last key that was pressed
*/
private int lastKey;

/**
* Paint the screen
*/
public void paint(Graphics g) {

/*
* Clear the screen
*/
g.setColor(BACKGROUND_COLOR);
g.fillRect(0, 0, getWidth(), getHeight());

/*
* Paint the message
*/
g.setColor(FOREGROUND_COLOR);

g.drawString("Press a key!", 0, 0, Graphics.TOP | Graphics.LEFT);

if (lastKey != 0) {
g.drawString("Key Code: " + lastKey, 0, g.getFont().getHeight(),
Graphics.TOP | Graphics.LEFT);
try {
g.drawString("Action: " + getGameAction(lastKey), 0,
2 * g.getFont().getHeight(),
Graphics.TOP | Graphics.LEFT);
g.drawString("Key Name: " + getKeyName(lastKey), 0,
3 * g.getFont().getHeight(),
Graphics.TOP | Graphics.LEFT);
} catch (Exception e) {
// ignore since alphabet keys will throw this exception
}
}
}

/**
* Handle key press
*/
public void keyPressed(int keyCode) {

lastKey = keyCode;
repaint();
}

/**
* Demonstrate keyRepeated events
*/
public void keyRepeated(int keyCode) {
System.out.println("Key repeated " + keyCode);
}
}
}
