[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - could not deserialize

[toni]

Hi,

I have an entity bean, which references an exception. Persiting the entity bean to the postgresql 7.4 works without problems.

However, I can't read/restore them, because I get the following exception:

org.hibernate.type.SerializationException: could not deserialize

Does anybody know how to avoid this? I think the code and annotations are fine. Here is the entity bean in question:


  | @Entity
  | @Name("systemMessage")
  | 
  | public class SystemMessage implements Serializable
  | {
  | @Id
  | @GeneratedValue(strategy = GenerationType.IDENTITY)
  | long id;
  | 
  | @Lob
  | String message;
  | 
  | @Temporal(TemporalType.TIMESTAMP)
  | Date creationDate = new Date(System.currentTimeMillis());
  | 
  | @Enumerated
  | SystemMessageType systemMessageType = SystemMessageType.INFO;
  | 
  | @Lob
  | Throwable throwable;
  | 
  | public SystemMessage()
  | {
  | super();
  | }
  | 
  | public SystemMessage(String message, SystemMessageType systemMessageType, Throwable throwable)
  | {
  | this.message = message;
  | this.systemMessageType = systemMessageType;
  | this.throwable = throwable;
  | }
  | 
  | public long getId()
  | {
  | return id;
  | }
  | 
  | public void setId(long id)
  | {
  | this.id = id;
  | }
  | 
  | public String getMessage()
  | {
  | return message;
  | }
  | 
  | public void setMessage(String message)
  | {
  | this.message = message;
  | }
  | 
  | public Date getCreationDate()
  | {
  | return creationDate;
  | }
  | 
  | public void setCreationDate(Date creationDate)
  | {
  | this.creationDate = creationDate;
  | }
  | 
  | public SystemMessageType getSystemMessageType()
  | {
  | return systemMessageType;
  | }
  | 
  | public void setSystemMessageType(SystemMessageType systemMessageType)
  | {
  | this.systemMessageType = systemMessageType;
  | }
  | 
  | public Throwable getThrowable()
  | {
  | return throwable;
  | }
  | 
  | public void setThrowable(Throwable throwable)
  | {
  | this.throwable = throwable;
  | }
  | } 
  |
