Description _ henriquemeira 2009-07-22 19:02:22 UTC 
About "Entity Classes from Database" option:

The NetBeans creates a java class aditional for table with more than one field on primary key. This class don't creates
a default constructor. So, we have the hint: "The class should have a no-arg, public or protected constructor.".

I tested on NB 6.5.1 too. The default constructor is created successfuly.

This problem breaks the excecution, raising the following sample exception:

Exception [EclipseLink-63] (Eclipse Persistence Services - 1.0.1 (Build 20080905)):
org.eclipse.persistence.exceptions.DescriptorException
Exception Description: The instance creation method [desktopapplication1.NfeDetPK.<Default Constructor>], with no
parameters, does not exist, or is not accessible.
Internal Exception: java.lang.NoSuchMethodException: desktopapplication1.NfeDetPK.<init>()
Descriptor: RelationalDescriptor(desktopapplication1.NfeDetPK --> [DatabaseTable(nfe_det)])

regards,

henrique.
