Can I put a static findByXandY() in my Entity?

Question

Hi,
The examples I find put @NamedQuery in the Entity. Then they put all the code to implement a findByXandY() method in the Session Bean that wants to locate the Entity for X and Y.
That seems a lot of excess code if I have say 10 Session Beans that all need to look up the Entity by X and Y!
Can I get a way with putting a static findBySandY() in the Entity class and then just call it from any Session Bean???
I mean first define MyEntity something like this:
@NamedQueries(
  {  @NamedQuery(name="findByXandY",
                 query="SELECT e FROM Employee e"
                 WHERE e.fieldX = :X, e.fieldY = "Y),
     @NamedQuery(...)
@Entity
public class MyEntity {
  static List findByXandY( EntityManager em, String X, String Y) {
    return em.createNamedQuery("findByXandY")
             .setParameter("X", "xxxx")
             .setParemeter("Y","yyyy")
             .getResultList();
}{code}
Then write my Session Bean something like this:
{code}@Stateless
public class MyServiceBean implements MyServiceLocal {
  @PersistenceContext(unitName="someName") //name assigned in persistence.xml
  private EntityManager em;
  // internal helper method used by the Session Bean
  private List findMyEntityByXandY (String x, String y) {
    return = MyEntity.findByXandY(em,x,y);
{code}
Any hope?
Thanks,

Opps. I forgot to put
String fieldX; and
String fieldY; and
their setters and getters in MY Entity.
And I guess my private method in the Session Bean is redundent ... silly because if this works, I can just use this line in any Session Bean that needs a MyEntity row whose relevant fields are "xx and "yy".
List MyEntity.findByXandY(em,"xx","yy");
