This article will explain in detail how to use eclipse to build J2ME development environment under Linux. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Do you know how to build a J2ME development environment with eclipse under linux? there are four main steps.

The process of building J2ME development environment with eclipse under linux

The first is the operating environment and software version:

1. Operating system: ArchLinux (updated to 20081204)

2.JDK environment: jdk-1_5_0_17-linux-i586.bin

Next address: http://java.sun.com/javase/downloads/index_jdk5.jsp

3.Eclipse environment: eclipse-java-ganymede-SR1-linux-gtk.tar.gz

Download address: http://www.eclipse.org/downloads/

4.J2ME version: J2ME_wireless_toolkit-2_2-linux-i386.bin

J2ME_wireless_toolkit-2_2-update_1-linux.zip

5. Download address: http://java.sun.com/products/sjwtoolkit/download-2_2.html

EclipseME environment: eclipseme.feature_1.7.9_site.zip

Download address: http://eclipseme.org/

Installation and configuration of JDK

Copy the jdk installation file to the homework/, in the current user directory to perform the installation directly.

User@~/homework$shjdk-1_5_0_17-linux-i586.bin

Set the jdk environment variable:

User@~/homework$exportJAVA_HOME=/home/kldscs/homework/jdk1.5.0_17 user@~/homework$exportCLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib user@~/homework$exportPATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

If you want to make the environment variables available after the system restart or the user logs out, you can write the contents of the command you just executed to the .bashrc file under the user's root directory, or the system environment variable control file

/ etc/profile

User@~/homework$vi~/.bashrc

User@~/homework$sudovi/etc/profile

Install Eclipse

Extract the Eclipse package:

~ / homework$tar-xvfeclipse-java-ganymede-SR1-linux-gtk.tar.gz

Double-click eclipse in ~ / homework/eclipse/ after pressurization and run it. If you need to define the jre environment, add your JRE path in Window- > Preferences- > Java- > InstalledJREs- > Add.

Select ~ / homework/workspace as the workspace directory here

Install WTK2.2

The command line goes to the directory where J2ME_wireless_toolkit-2_2-linux-i386.bin is stored

User@~/homework$shJ2ME_wireless_toolkit-2_2-linux-i386.bin Setuphasenoughinformationtostartcopyingtheprogramfiles. CurrentSettings: DestinationDirectory / home/user/homework/WTK2.2/ JVMFolder / home/user/homework/jdk1.5.0_17/bin/

If the installation is complete, the following screen appears

Extractingtheinstallationfiles... DocumentationfortheJ2MEWirelessToolkitversion2.2isinthefile / home/user/homework/WTK2.2/index.html InordertostartusingtheJ2MEWirelessToolkit,pleaserun / home/user/homework/WTK2.2/bin/ktoolbar

Patch WTK and extract J2ME_wireless_toolkit-2_2-update_1-linux.zip to the WTK2.2 installation directory.

User@~/homework$cpJ2ME_wireless_toolkit-2_2-update_1-linux.zip./WTK2.2/ user@~/homework$cdWTK2.2/ user@~/homework/WTK2.2 $unzipJ2ME_wireless_toolkit-2_2-update_1-linux.zip Archive:J2ME_wireless_toolkit-2_2-update_1-linux.zip replacebin/libzayit.so? [y] es, [n] o, [A] ll, [N] one, [r] ename:A

Test whether the installation is successful:

User@~/homework/WTK2.2$ cd./bin/ user@~/homework/WTK2.2/bin$./ktoolbar WTKOTAserverstarted...

If the installation is successful, a GUI window will appear.

Install EclipseME

# first decompress eclipseme.feature_1.7.9_site.zip user@~/homework$mkdireclipseme user@~/homework$cpeclipseme. Feature_1.7.9_site.zipeclipseme/ user@~/homework$cdeclipseme/ user@~/homework/eclipseme$unzipeclipseme. Feature_1.7.9_site.zip

Start Eclipse,Help- > SoftwareUpdates- > AvailableSoftware- > AddSite, fill in "/ home/user/homework/eclipseme" and select "EclipseME"-> Install.

There will be an EclipseME option under the Eclipse,Help menu when the installation restarts successfully.

Configure WTK in Eclipse

Start Eclipse,Window- > Preferences to enter the configuration window.

Select the J2ME menu and fill in the WTK installation directory in WTKRoot

J2ME-> DeviceManagement- > Import, enter / home/user/homework/WTK2.2/bin for directory entries, and refresh button Refresh

Determine the Finsh, and then choose a mobile phone skin that you prefer.

J2ME-> Packaging- > Obfuscation, fill in the WTK installation directory / home/user/homework/WTK2.2.

You can write a simple HelloWorld program to test one:

Importjavax.microedition.lcdui.Display; importjavax.microedition.lcdui.Form; importjavax.microedition.midlet.MIDlet; importjavax.microedition.midlet.MIDletStateChangeException; publicclasshelloextendsMIDlet {Displaydisplay; publichello () {super (); display=Display.getDisplay (this);} protectedvoiddestroyApp (booleanarg0) throwsMIDletStateChangeException {} protectedvoidpauseApp () {} protectedvoidstartApp () throwsMIDletStateChangeException {Formform=newForm ("AnotherHelloWorld"); form.append ("HelloWorld!"); display.setCurrent (form) }} on how to use eclipse to build J2ME development environment under Linux is shared here.
