See the exception:

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError:    com/toedter/calendar/JDateChooser
    at run$1.run(run.java:9)

Whenever your class is not available for the class Loader (ie your .class file) then we will get this exception.

Read the below post for better understanding:
