This article mainly shows you "how to configure and use Jcreater+MotoJ2SDK", the content is easy to understand, clear, hope to help you solve doubts, the following let the editor lead you to study and learn "how to configure and use Jcreater+MotoJ2SDK" this article.

Suppose the installation path is as follows:

JCreator D:Program FilesXinox SoftwareJCreator LE

Motoj2sdk D:Motoj2sdk

JDK D:jdk1.3.1

Note: to activate the simulation environment, run D:MotoJ2SDKgenericscripts unConstructor.bat

Select the phone model, select the language, select normal, and then "create".

After starting Jcreater, my configuration is as follows:

Select Configure- > Options- > JDK Profiles in the first step

Note: be sure to create a new profile and select "D:jdk1.3.1"

Change the name to "J2ME 388"

Add classes path "D:Motoj2sdklib"

Add documentation path "D:Motoj2sdkdocs"

Move the following two lines to the top respectively.

Select Configure- > Options- > JDK Tools in the second step

Select Complier

Select and edit it.

Change parameters to-classpath D:/motoj2sdk/lib $[JavaFiles]

Step three

Select Configure- > Options- > Tools

Click "New" to select DOS command

The name is "Preverifier".

Replace arguments with d:Motoj2sdkinpreverifier.exe-classpath "d:Motoj2sdklib"-d. .

Change initial directory to "$[PrjDir]"

Step 4

Follow the above method to New a DOS command

Name: "Run Emulator"

Replace arguments with "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"

Replace initial directory with "d:Motoj2sdkin"

Ok! The editing tool has been configured!

Build a new project? Select Empty Project

Give it another name, such as: test

Then jcreater automatically generates directory test in your working directory

Then new a file and choose java File.

Write your original code and save it such as: test.java

Select add file in Project

Then select your test.java just now.

Note: no package

Compile "Preverifier in tools for pre-audit" Run Emulator in tools to simulate

Example of test.java: is the function to capture keyboard input ascII?
