Oracle Java ME SDK 8.3.1 is available. We are pleased to announce an update for the Oracle Java ME Software Development Kit (SDK). Oracle Java ME SDK is a standalone development environment and a set. Why Java me platform 3.4 does not support on netbeans 8.2 Question Closed 04e3b2c6-443c-4121-a057-6c5fc91d5ac9 336 views 0 comments 0 points Started by 04e3b2c6-443c-4121-a057-6c5fc91d5ac9 Oct 15, 2017 3:31AM. I just tried it, with NetBeans 7.2.1, and the Java ME SDK 3.2. The version of NetBeans I used was from this download page and was the Java EE version. One easy thing to miss in the steps below is that on this download page, you need to download both the Java ME SDK and the Java ME SDK Plugin for Netbeans. Not just the plugin. A new release of Oracle Java ME Embedded 8 is now available for download on OTN. Oracle Java ME SDK 8.2 is also delivering the embedded development experience to.

The Oracle Java ME SDK 3.4 platform is a sophisticated and useful tool for programmers who want to develop embedded applications. The Oracle Java ME SDK 3.4 platform can be used successfully and easily with the NetBeans 7.3.1 Integrated Development Environment, as well as the Eclipse (Indigo 3.7, Juno 4.2, or Kepler 4.3) IDE.

Note: The Oracle Java ME Embedded 3.4 runtime is fully implemented inside Oracle Java ME SDK 3.4 software. So, there is no need for you to independently install Oracle Java ME Embedded 3.4 software.

This chapter provides information you need to ensure that your Microsoft Windows XP (32-bit) or Windows 7 (32-bit or 64-bit) platform is correctly set up for working with Oracle Java ME SDK. Both Windows XP and Windows 7 must include the most recent Microsoft service packs.

Installing the Java SE Platform

To properly run the Oracle Java ME SDK software and its associated Tools, you must have Java Platform, Standard Edition (Java SE), Version 7, Update 25 (or later) installed on your computer.

This guide assumes you have already installed the Java SE platform. If you have not installed Java 7, Update 25, you can download it from the following location:

http://www.oracle.com/technetwork/java/javase/downloads

The installation of Eclipse Indigo 3.7 requires Java 6, Update 17 as the reference platform. It may work with other Java versions, but it is not recommended by Eclipse. To get Java 6, Update 17:

http://www.oracle.com/technetwork/java/javase/archive-139210.html

The Java SE platform must also be in your PATH.

Setting and Verifying Your Java SE PATH

To verify if Java SE platform is set in your PATH:

1. In the Windows command line, type:

   C:>echo %PATH%

2. If Java SE is properly installed, you see a path to the default installation directory:

   C:>Program FilesJavajdk1.7.0_x

3. If not, you need to add Java SE to your PATH.

   
   

   Note: Setting the PATH may require using a Windows short name. To see top-level Windows short names, type C:>dir /x

   
   

4. Set the Java SE variable, JDK_DIR:

   C:>set JDK_DIR=C:Program FilesJavajdk1.7.0_25

5. Add JDK_DIR to your PATH:

   C:>set PATH=%PATH%;%JDK_DIR%bin

6. To verify the version of your Java SE platform, type:

   C:>java -version

The version number shown in the output should be version 1.7.0_25 or higher.

Installing the Oracle Java ME SDK Platform

Follow these steps to install the Oracle Java ME SDK 3.4.

1. If you have previously installed an earlier version of Oracle Java ME SDK, uninstall the previous version as shown below.

   
   

   Note: If you are installing Oracle Java ME SDK for the first time, skip to Step 2.

   
   

   • If you have Oracle Java ME SDK data to save, copy it to a safe location before continuing.

   • In the Windows system tray, right click the emulator icon and choose Exit.

   • From the Windows Programs menu, select the previous version and choose Uninstall from the submenu. The Installer opens.

   • On the first page check the option to remove the user data directory.

   • Follow the prompts.

2. Download the SDK from:

   http://www.oracle.com/technetwork/java/javame/javamobile/download/sdk

3. Double-click the executable. When the installer starts, follow the prompts.

Installing and the Starting the NetBeans IDE

If you do not already have the NetBeans 7.3.1 IDE installed on your system, you can download it here:

https://netbeans.org/downloads/

Once you have downloaded the NetBeans installation module, do the following.

1. Double click the NetBeans executable file, netbeans-7.3.1-windows.exe.

2. When the NetBeans Installer starts, follow the prompts.

For more information on working with the NetBeans IDE, see

Installing and Starting the Eclipse IDE

If you do not already have Eclipse Indigo 3.7 installed on your system, you can download it here:

http://www.eclipse.org/downloads/packages/release/indigo/sr2

You can download Juno 4.2 here:

You can download Kepler 4.3 here:

http://www.eclipse.org/downloads

Once you have downloaded the Eclipse Kepler 4.3 executable, eclipse-java-kepler-ga-offline-installer-windows.exe, double-click -it to start running and follow the prompts.

Note: For Eclipse Kepler, you must also specify a directory location in which to store your Eclipse project files, as shown in Step 3, below.

For the Eclipse Indigo 3.7 or Juno 4.2 installation modules, do the following to install Eclipse on your system:

1. In the C:Program Files directory, unzip the Eclipse distribution zip file.

2. In the C:Program Fileseclipse directory, click eclipse.exe to launch Eclipse.

3. When the Select a Workspace dialog box appears, specify a directory location in which to store your Eclipse project files. Click OK.

Verifying the UART Prefix

Lastly, verify that the deviceaccess.uart.prefix property in the jwc_properties.ini file contains a prefix that will make it easy to convert the UARTConfig.portNumber value to a platform-specific port name. This is used for COM port discovering.

Note: If you are planning to work only in emulation, you can skip this step.

In the Win32 environment, the property should be set to COM so that appending a port number maps correctly to the proper port name. Add the following line to the jwc_properties.ini file:

deviceaccess.uart.prefix=COM

The jwc_properties.ini file is found in the following location:

C:Java_ME_platform_SDK3.4runtimesimpngbin

Using the Eclipse integrated development environment, you can create and test embedded applications using a graphical development environment.

Note: The examples in this chapter use the Eclipse Indigo 3.7 platform.

Installing the Oracle Java ME SDK Eclipse Plugin

The Oracle Java ME SDK Plugins are the same for the Kepler 4.3, Juno 4.2, and Indigo 3.7 platforms.

To download the Oracle Java ME SDK Plugins file for Eclipse (oracle-jmesdk-3-4-rr-eclipse-plugins.zip), go to the following location:

Installing Plugins on Eclipse Kepler 4.3 and Juno 4.2

On Eclipse Kepler 4.3 and Juno 4.2, installing the Oracle Java ME SDK plugins requires the Eclipse Mobile Tools for Java (MTJ) toolkit. The MTJ is not bundled with Juno and must be installed manually, before installing the Eclipse plugins.

To install the Eclipse Mobile Tools for Java toolkit:

1. Go to Help > Install New Software.

2. In the “Work with” field, enter this URL:

   http://download.eclipse.org/mtj/updates/1.1.2/stable/

3. Click Add.

   When the plugins are discovered, open the Mobile and Device Development Tools hierarchy and check Mobile Tools for Java Examples and Mobile Tools for Java SDK. Click Next.

   On the installation screen select all plugins and click Finish then click OK.

4. A Juno plugin named org.eclipse.jetty.server_<version>.jar conflicts with the MTJ libraries when the plugin version is higher than 6.

   If the org.eclipse.jetty.server version is higher than 6 you must prevent it from loading by changing its name so the JAR file is not parsed. Locate the file in the plugins directory of your Juno installation and change the extension from .jar to something else.

   For example, change it to: org.eclipse.jetty.server_<version>.old

Note: Once you have installed the MTJ toolkit for Eclipse Kepler 4.3 or Juno 4.2, the procedure for installing the Oracle Java ME SDK plugins is the same as for Eclipse Indigo 3.7. See 'Installing Plugins on Eclipse Indigo 3.7'.

Configuring Eclipse

To configure Eclipse, follow these steps:

1. Select Window > Open Perspective > Other and choose Java ME, as shown in Figure 4-5. Click OK.
