可以用模拟器调试。
比如用jcreator +motolaraSDK (388)
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”
Adddo
cumentation 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 $[JavaFiles]
第三步
选择 Configure->Options->Tools
点击“New”选择do
S command
名字为“Preverifier”
将 arguments 换为 d:/Motoj2sdk/bin/preverifier.exe -classpath "d:/Motoj2sdk/li
b" -d . .
将 initial directory 变为 “$[PrjDir]”
第4步
按上面的方法在New一个do
S command
名字:“Run Emulator”
将 arguments 换成 “java -Djava.library.path=d:/MotoJ2SDK/lib -classpath "d:/M
otoJ2SDK/bin/Emulator.jar";"d:/MotoJ2SDK/ConfigTool.jar" com.mot.tools.j2me.em
ulator.Emulator -classpath$[PrjDir];"d:/MotoJ2SDK/lib" -deviceFile d:/MotoJ2SD
K/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。
