> 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
