Answer 1

You must provide with the code.

Anyway, from the Java Docs, class 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.
