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。
