Java Micro Edition development – annoying emulator error
Posted by Amit Rathore on March 21, 2007
After a long time, I recently started playing with the Java Micro Edition again. Many years ago, I had downloaded and installed the Wireless Toolkit from Sun’s website (then in beta), and had hacked together common mobile games – snake, hangman, and the like.
So, when I downloaded the toolkit this time (v2.5 now), it was annoying to find that I couldn’t even seem to run a basic midlet without the emulator barfing at start up time, with an inexplicable ‘Uncaught exception java/lang/ArrayIndexOutOfBoundsException’ – no line numbers, nothing. The emulator screen wouldn’t list the midlet name either, so clicking on the soft button would simply print the same exception message again.
Google was of limited help. More annoying.
Finally, I just played around with different configurations during launching the midlet, and when running it in “class” mode (you have to specify the midlet class), it seems to work.
So there’s a work-around for you.
