Java ME SDK 3.0.5 Known Problems

The following are the known issues and workarounds for Java ME SDK 3.0.5.

  • Java ME SDK 3.0.5 bundled with NetBeans 7.1.1+ might not run on JDK 7 if a proxy is used to connect to the internet.

    In JDK 7, handling of network proxies was re-designed and as a result ME SDK 3.0.5 might not start when installed with JDK 7.

    If you use a proxy to connect to the internet, explicitly add "localhost" and "127.0.0.1" as exceptions for the Windows internet connections proxy settings.

  • In rare cases you might have more than one instance of the Java ME SDK 3.0.5 in NetBeans.

    This can happen if:

    • You are running 7.1.1 and you installed the updated plugin before April 2012.

    • You are running 7.1.1 and you circumvented NetBeans autoupdate and manually downloaded and installed a version 3.0.5 plugin.

    To avoid problems with device manager conflicts you must set the Device Manager to use the version installed with 7.1.1.

    1. Select Tools > Java ME > Active Device Manager and choose the version installed in the /mobility directory as the default.

    2. In your Windows System tray, right click on the Device Manager Icon and choose Exit.

    3. Wait for the Device Manager to restart (the icon reappears in the System tray).

  • If both Java ME SDK 3.0 and Java ME SDK 3.0.5 are installed two versions of each emulator are listed when you use the keystore manager to export a keystore file to an emulator. You cannot differentiate which emulator belongs to 3.0 and which belongs to 3.0.5.

    You can export the keystores to both emulators.

  • The Java ME SDK uninstaller does not uninstall plugins from NetBeans.

    In NetBeans, select Tools > Plugins to open the plugins manager and manually uninstall the plugins. In the Installed tab, check the "Show details" box and select the plugins in the category "Java ME SDK Tools", then click the Uninstall button.

  • When using MMAPI you see the message "Unable to create native player".

    Java ME SDK has been pretested with DirectShow filters from the K-Lite Mega Codec Pack version 4.8.0. If creation of an MMAPI player for a particular content type fails, install the corresponding DirectShow filter on the system.

  • Network Monitor seems to hang instead of attaching.

    1. Close the Network Monitor view.

    2. Exit the Device Manager and wait until it is restarted by NetBeans.

    3. To start the Network Monitor for a particular project, right-click the project and select Profile, choose Network Monitor, and select Run.
