Hi all,
I have an entity, named AdatlapElozetesR, wich looks like this:
| package mypackage;
|
| import java.util.*;
| import javax.persistence.*;
|
| @Entity
| @Table(name = "ADATLAPELOZETESR", uniqueConstraints = {})
| public class AdatlapElozetesR implements java.io.Serializable {
|
| private static final long serialVersionUID = -7341044940631282534L;
| private Integer id;
| private Date datum;
|
| public AdatlapElozetesR() { }
|
| public AdatlapElozetesR(Integer id,
| Date datum) {
| this.id = id;
| this.datum = datum;
| }
|
| public AdatlapElozetesR(AdatlapElozetesR p_adatlapelozetesr) {
| this.id = p_adatlapelozetesr.getId();
| this.datum = p_adatlapelozetesr.getDatum();
| }
|
| @Id
| @Column(name = "id", unique = true, nullable = false, insertable =
true, updatable = true)
| @SequenceGenerator(name="SQC_ALE",
sequenceName="ADAT.SQ_ADATLAP_ELOZETES", allocationSize=1)
| @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SQC_ALE")
| public Integer getId() { return this.id; }
| public void setId(Integer id) { this.id = id; }
|
| @Temporal(TemporalType.DATE)
| @Column(name = "datum", unique = false, nullable = false, insertable =
true, updatable = true, length = 13)
| public Date getDatum() { return this.datum; }
| public void setDatum(Date datum) { this.datum = datum; }
|
| }
|
To manage this entity I use a session bean:
| package mypackage.adat;
|
| import java.sql.*;
| import java.text.Format;
| import java.text.SimpleDateFormat;
| import java.util.*;
| import javax.ejb.Stateless;
| import javax.ejb.TransactionAttribute;
| import javax.ejb.TransactionAttributeType;
| import javax.naming.InitialContext;
| import javax.sql.DataSource;
| import javax.persistence.EntityManager;
| import javax.persistence.PersistenceContext;
| import javax.persistence.Query;
| import org.apache.log4j.*;
| import org.hibernate.*;
| import org.hibernate.cfg.*;
|
| import mypackage.AdatlapElozetesR;
|
| @Stateless
| public class AdatlapElozetesRBean implements AdatlapElozetesRRemote,
AdatlapElozetesRLocal, java.io.Serializable {
|
| private static final Logger log =
Logger.getLogger(AdatlapElozetesRBean.class);
| @PersistenceContext(unitName="persistUniter")
| private EntityManager em;
|
| public void persist(AdatlapElozetesR transientInstance) {
| //AdatlapElozetesR n = new AdatlapElozetesR(transientInstance);
| System.out.println((transientInstance == null ?
"transientInstance NULL" :"transientInstance OK, "+transientInstance));
| try {
| em.persist(transientInstance);
| log.debug("persist successful");
| } catch (RuntimeException re) {
| log.error("persist failed", re);
| throw re;
| }
| }
|
| ...
| }
|
And my test client looks like this:
| package mypackage.test;
|
| import java.util.*;
| import javax.naming.InitialContext;
|
| import org.hibernate.*;
| import org.hibernate.cfg.*;
|
| import mypackage.adat.*;
| import mypackage.*;
|
| public class AdatlapElozetesRTest {
|
| AdatlapElozetesRTest() {
| System.out.println("AdatlapElozetesRTest()");
| }
| private void CreateAdatlapElozetesR() {
| System.out.println("CreateAdatlapElozetesR()");
| AdatlapElozetesR ale = new AdatlapElozetesR(new Integer(0),
| new
Date());
| System.out.println((ale == null ? "ale NULL" : "ale OK"));
| try {
| Properties properties = new Properties();
| properties.setProperty("java.naming.provider.url",
"jnp://localhost:1099");
| properties.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming");
|
properties.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
| InitialContext ctx = new InitialContext( properties );
| AdatlapElozetesRInterface aei =
(AdatlapElozetesRInterface)ctx.lookup("AdatlapElozetesRBean/remote");
| System.out.println((aei == null ? "aei NULL" : "aei
OK"));
| aei.persist(ale);
| } catch(org.hibernate.PersistentObjectException poex) {
| System.out.println("feliras()\n"+poex);
| //ex.printStackTrace();
| } catch(Exception ex) {
| System.out.println("feliras()\n"+ex);
| //ex.printStackTrace();
| }
| }
| public static void main(String[] args) {
| AdatlapElozetesRTest t1 = new AdatlapElozetesRTest();
| t1.CreateAdatlapElozetesR();
| t1 = null;
| }
| }
|
When I run the client, to insert a new row in my table I get this error:
| 21:47:37,032 INFO [STDOUT] transientInstance OK, [EMAIL PROTECTED]
| 21:47:37,032 ERROR [AdatlapElozetesBean] persist failed
