If I use a @MappedSuperclass (which is a very useful annotation btw) I have to manually copy any queries I want with taht class up to all subclasses.  The binder should check any mapped superclasses and pull those named queries up.  i.e.

/**
 * Base User class that different projects user classes derive from. 
 * Hibernate annotations doesn't pick up that query, so you have to copy it up to your subclass
 */
@MappedSuperclass
@NamedQueries({
	@NamedQuery(name="User.findByLoginName",
			query="FROM User WHERE loginName = ?")   // this is useless down here, i just put it here for reference
})
public class BaseUser<PK extends Serializable> extends IdEntity<PK> {

	private static final long serialVersionUID = -4443522925041212381L;

	protected String loginName;
	
	@Column(unique=true)
	public String getLoginName() {
		return this.loginName;
	}

	public void setLoginName(String loginName) {
		this.loginName = loginName;
	}
}

/**
 * Custom user class for a certain application
 */
@Entity
@Table(name="tbl_user")
@GenericGenerator(name=IdGen.NAME, strategy=IdGen.AUTO)
@NamedQueries({
	@NamedQuery(name="User.findByLoginName",
				query="FROM User WHERE loginName = ?")  // had to copy this up from the base class
})
public class User extends BaseUser<Short> {

	private static final long serialVersionUID = -6199544722824321999L;

	private String firstName;
  ...
}

so in short it would be nice if the scanner would check for that and bind any named queries up to the subclass
