http://java.sun.com/j2se/1.4.2/docs/api/java/lang/InstantiationException.html:
Thrown when an application tries to create an instance of a class using the
newInstance method in class Class, but the specified class object cannot be
instantiated because it is an interface or is an abstract class.
This makes me think that "br.com.leiarock.mapeamento.Generos" is not a
subclass of CayenneDataObject, or that it's been manually set to be
abstract. Hope this helps. Make sure that you are creating Generos using
the Cayenne Modeler tool.
Your code hierarchy should look like one of the following patterns:
public class Generos extends CayenneDataObject
or
public class [superclass] extends CayenneDataObject
public class Generos extends [superclass]
or
public class _Generos extends CayenneDataObject
public class Generos extends _Generos
or
public class [superclass] extends CayenneDataObject
public class _Generos extends [superclass]
public class Generos extends _Generos
