Wireless toolkit emulator stopped working

[rdlugosz]

I have the problem with starting the wireless toolkit emulator under NetBeans 6.8. After the installation of the Sun Java Wireless Toolkit 2.5.2_01 for CLDC everything worked ok for a weak. I was able to compile and test different projects (midlets). Yesterday something happened. I performed the update of my Ubuntu and after that the emulator is no longer working. Maybe it is not the reason of the problem, but I am not sure. I am receiving the message as below (the jar file is being created in the dist directory, but emulator does not start anymore. To be sure that the problem is not related to the code itself I create a simple Hello World midlet, which previously worked ok.

It looks like the problem is with the emulator, as other Java projects (applets and others) work fine.

Does anybody has an explanation of this problem? I was exploring different forums, but without the positive result.

Check you java installation first. Try to run the emulator just by
typing ./emulator -version, you should see some normal output.
