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 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]”

第四步 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。
