Hi,
I'm trying to create an "IdEntityBean" superclass:
package test.ejb.entity;
import java.util.*;
import javax.persistence.*;
@MappedSuperclass
public abstract class IdEntityBean {
@Id
@GeneratedValue(strategy = GenerationType.AUTO, generator = "Seq")
Integer id;
public Integer getId() { return id;}
}
I can extend another class from this one:
package test.ejb.entity;
import java.util.*;
import javax.persistence.*;
import javax.ejb.*;
@Entity
@Remote
@Inheritance
@Table(name="a")
@NamedQuery(
name="ABean.findAll",
query="SELECT o FROM ABean o ORDER BY o.m_sInfo DESC"
)
public class ABean extends IdEntityBean {
@SequenceGenerator(name = "AlfaSeq", sequenceName = "Seq")
@Column(name="info")
String m_sInfo;
@PrePersist
public void setCreateInfo() {
m_sInfo = "";
}
public String getInfo() { return m_sInfo;}
public void setInfo(String info) { m_sInfo = info;}
}
but when I deploy I obtain this error:
