Hi kathir,

a look at the API documentation would help.

Quote from ClassNotFoundException

Thrown when an application tries to load in a class through its string name using:

  • The forName method in class Class.
  • The findSystemClass method in class ClassLoader .
  • The loadClass method in class ClassLoader.

  • but no definition for the class with the specified name could be found.



    Qute from NoClassDefFoundError

    Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.

    The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.
