I update a EJB Entity and after insert call the record is corrupted...
A value 147.163.0.61 is inserted as 沿47.163.0.61.
The first character is corrupted.
My solution is a persist (with flush) of partial record (with many object attributes insertable=false) and a merge.
I think that problem is many attributes of type java.util.Date. Attributes of type Date are updated but but not inserted.

@Entity
@Table(name = "TB_LOG")
public class Log implements Serializable {

 private static final long serialVersionUID = 1L;

 @Id
 @Column(name = "OID", updatable = false)
 @SequenceGenerator(name = "SEQUENCE", sequenceName = "SEQ_TB_LOG_WSR", allocationSize = 1)
 @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQUENCE")
 private long oid;

 @Column(name = "CLI", nullable = false, updatable = false)
 private String clientAddress;

 @Lob
 @Basic(fetch=FetchType.LAZY)
 @Column(name = "SOA_REQ", nullable = true, insertable=false)
 private String request;

 @Lob
 @Basic(fetch=FetchType.LAZY)
 @Column(name = "SOA_RES", nullable = true, insertable=false)
 private String response;

 @Column(name = "DAT", nullable = true, insertable = false)
 private Date date;

 ....
 ....
}

This is the only corrected method to store object Log (others cause curruption)

 Log log = new Log();
 log.setClientAddress(new String(address.toString())); // non so perchè ma necessita ricreare la stringa
 // altrimenti sulla INSERT del db accade un casino
 // !!! BOOOOO
 em.persist(log);
 em.flush();

 log.setDate(date); // non so perchè ma non cambiare l'ordine della persist e della merge, altrimenti i dati
 // su db saranno corrotti!!! BOOO
 log.setRequest(request);
 log.setResponse(response);

 em.merge(log);
 em.flush();

My configuration is:
- JBoss 4.0.5
- Seam 1.2.1.GA
- Hibernate core updated to 3.2.5
- Oracle Database 8.1.7
