Emulator problem with 64bit Architecture

Question

Hi All,
I'm having a problem with my WTK Version 2.5.2 for CLDC.
I'm using Ubuntu 10.04 x86_64 version and JDK1.6.0_21 64bit.
When I run a simple MIDP application it gives the below error:
java.lang.UnsatisfiedLinkError: /usr/local/netbeans-6.9.1/mobility/WTK2.5.2/bin/sublime.so: /usr/local/netbeans-6.9.1/mobility/WTK2.5.2/bin/sublime.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

When I was searching for a solution I found post related to the same error "http://forums.sun.com/thread.jspa?threadID=5217069"
and there I got the solution. from the post send by don_mahantya post 41.
I was facing the same problem as well.
I use Netbeans 6.7.1 on openSUSE 11.1 64-bit and I would get the error whenever I tried to invoke the Java ME emulator.
All I did was edit the emulator script i.e.
$ vi /opt/netbeans/netbeans-6.7.1/mobility8/WTK2.5.2/bin/emulator
and I added the path to the 32-bit Java directory
javapathtowtk=/opt/java/jdk1.6.0_14-32bit/bin/
NOTE: Make sure to put 'bin/' at the end
Hope it helps.. works for me The same solution works with my case very well.
I wonder why can't I use Java 64bit with this WTK ?
Is there a diferent WTK version to use with 64bit? I'm using WTK which comes with NetBeans 6.9.1

Answer 1

I had the exact same problems (MS Natural Ergonomic Keyboard 4000 + Intellitype 7.0), and it was driving me nuts. But I've found a solution (as laid out on my blog @ http://carlo.zottmann.org/2009/09/11/upgrading-to-snow-leopard/):
Get Ukulele (http://scripts.sil.org/cms/scripts/page.php?siteid=nrsi&itemid=ukelele), the Unicode keyboard layout editor. After downloading it, look around the DMG and find these two files: LogitechGerman.keylayout and LogitechGerman.icns. After copying them to the /Library/Keyboard Layouts/, all that's left is opening the Language & Text preference pane and activating the "Logitech German" layout.
At that point, the Intellitype drivers can be uninstalled, but that'll disable most of the keyboard's special function keys (1-5, ★, home/search/email/calculator).
Hope this helps!
