    Question Exception in thread "main" java.lang.NoClassDefFoundError: MyApp

    hi all,

    I'm getting the mentioned error while trying to run my app. I'm using TextPad to compile and run my app. i have also try to run from command prompt but it shows same error. I have checked my jdk bin dir and jre bin dir. Both of them are the correct path. where did I go wrong?

    rgds,
    jpdbay

    Silly question, but do you have a main class?

    Have you tried explicitly putting the classpath when running from the command prompt?

    I think your custom enviroment varibales are messed up. Do a search on how to set your CLASSPATH in the enviroment variable.

    Attach software www.cajoon.com to your Java environmeny (J2SE, J2EE) and get 'root-cause' for every exception
