Solution

  • I experienced a similar thing when trying to add an external library (I was trying to use javax.mail). I had a separate program that worked perfectly but when implemented into my codename one project I got the same java.lang.NoClassDefFoundError error. The issue is codename one does not work with external libraries, only codename one extensions. If you go into preferences and look at the extensions tab, you can search for a library that does a similar thing.
