I think you might be after something like JBoss Envers, althought I believe it's a part of Hibernate Core. I would verify.

I just want to know how to do this...

I have entity class and I added version attribute for represent tables 'version' field like this..

Code:

    private int version;

    @Version
    @Column(name="VERSION", nullable=true, length=10)
    public int getVersion() {
        return version;
    }

    public void setVersion(int version) {
        this.version = version;
    }

I have table field named 'VERSION' in my oracle database. its type is number and default value is 0.

The problem is this doesn't work. Should I do anything else apart from this ?

What are you expecting, and what happens instead?

Hi

I dont see any problem , i think it should work.

Example :

@Column(name = "OptLockVersion")
@Version
private int m_version;

public int getOptLockVersion() {
return m_version;
}

Generally Attributes nullable=true, length=10 for your version @Column, i think should not be there.
