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;
}
}
