Hello again, i have seen that HHH-6328 Awaiting Response is the same problem.
@Entity
@Table(name = "datas_de", catalog = "service")
@NamedQuery (name="selectInfosDe", query="SELECT d FROM MyDatas d")
public class MyDatas implements java.io.Serializable

The classname, here MyDatas, ist not the same and all runs correct and i get my datas.

With @Table(appliesTo="datas_de") from Hibernate,
this is not possible, the name in appliesTo must be
equal to the classname.

Have i overseen something?
