JDK 64bit + WTK on Ubuntu

If you installed WTK (wireless toolkit) on your Ubuntu 64bit system you'll most probably have a little problem. When you try to run the mobile emulator you get

java.lang.UnsatisfiedLinkError: /usr/local/netbeans-6.9/mobility/WTK2.5.2/bin/sublime.so: /usr/local/netbeans-6.9/mobility/WTK2.5.2/bin/sublime.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

Fix (execute in a terminal):

sudo apt-get install ia32-sun-java6-bin
sudo gedit /usr/local/netbeans-6.9/mobility/WTK2.5.2/bin/emulator

edit javapathtowtk=
