 Post subject: SerializationException while retrieving an integer ID

This is a bummer: I am persisting an object using EntityManager.persist() in a transaction which is properly commited.

Later on I try to retrieve that same object from storage using find(). You can imagine my surprise to receive a SerializationException when Hibernate tries to read the ID property of the object it had earlier persisted. The ID property is database (Oracle 10g) type NUMBER(10) generated by Hibernate using hbm2ddl, and its generated value is currently lower than 100 (therefore valid Integer).

Detailed information can be found below:

Hibernate version: Core 3.2.6 GA, Annotations 3.3.1 GA (also tried 3.3.0 GA), EntityManager 3.3.2 GA (also tried 3.3.1 GA)

Name and version of the database you are using: Oracle 10g

   ... 32 more


The two most important pieces in this piece of logging are: a query that is successfully executed and this line:
INFO org.hibernate.type.SerializableType could not read column value from result set: SEARCHID10_1_
This column had the same value as the parameter that was passed in: 62. It is declared in my entity class as:
Code:
    @Id
    @Column(name = "SEARCHID")
    @SequenceGenerator(name = "SearchSequence", sequenceName = "SEQ_ESETOOLSEARCH")
    @GeneratedValue(generator = "SearchSequence", strategy = GenerationType.AUTO)
    private Integer id;


This entity and all of its properties are serializable.

Anyone has a clue about what could be going on here? This is driving me nuts.

Just curious...Do you get the same exception when you use load, as opposed to get?

Hi,
It's probably unrelated, but shouldn't you avoid "GenerationType.AUTO" ? It doesn't look like appropriate for a "@SequenceGenerator".
