I am reading Vikram Gopal's tutorial on how to write MIDlets. Their example shows the date and time when you launch it. However, when I use the emulator provided with J2ME Wireless Toolkit 2.2, it just disappears when I it launch. A look at the command line says "ALERT: java/lang/ClassFormatError: Bad Version Information". Here's the code it's right out the tutorial:

DateTimeApp.java


Manifest.mf


DateTimeApp.jad

Same code works well on WTK 2.5.
