Hi,
I am having following two classes, modified the code as follows
@Entity
@Table(name = "LOG_DB2")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(discriminatorType=DiscriminatorType.CHAR)
@DiscriminatorValue(value="S")
public class A {
@Column(name = "LOG_ID")
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private long id;
@Column(name = "TAG")
private String tag;
@Column(name = "SUBTAG")
private String subtag;
@Column(name = "HOST_NAME")
private String hostName;
@Entity
@Table(name = "LOG_DB2")
@DiscriminatorValue(value="C")
public class B extends A {
@Column(name = "INSTANCE_NAME")
private String instanceName;
@Column(name = "DB2_TIMESTAMP")
private Timestamp db2Timestamp;
@Column(name = "DB_ALIAS")
private String dbAlias;
@Column(name = "DB_PARTITION")
private int partitionNum;
I am facing the problem while retriveing the data from the database, the
following is the code and highlighted the
problem area in the code
em=ServiceLocator.getOpenJPASession("audit");
em.getTransaction().begin();
Query q = em.createQuery("select ad from B ad");
List<B> logs = q.getResultList();
for (B l : logs) {
System.out.println("Host Name is : "+l.getHostName()+" Instance Name is
"+l.getInstanceName());
em.remove(l);
}
em.getTransaction().commit();
em.close();
The following error occurs
<0.9.7-incubating nonfatal general error>
