Hibernate version: 3.2.1

I'm interested in using a table generator and I've seen mention of different implementations but I don't know how to actually configure hibernate to use anything other than the default. Please note, I am using JPA along with annotations.

So, with that said, how do I configure hibernate to use a table generator other than the default?

Thanks in advance, Tom

though I haven't personally implemented it

Code:

@TableGenerator(name = "unique_generator_name",table="table_name",initialValue=1,...)
public getId(){
    return id;
}

The api should help you with the rest, lookup @TableGenerator, http://www.hibernate.org/hib_docs/ejb3-api/

Thanks for offering the advice (and the pointer to the documentation) but unfortunately, that really doesn't tell me how to use an implementation such as the org.hibernate.id.MultipleHiLoPerTableGenerator class.

Here's what I've uncovered (use the GenericGenerator) as in the following ...

Code:

@Id
@GeneratedValue(generator="hibseq")
@GenericGenerator(name="hibseq", strategy = "org.hibernate.id.enhanced.TableGenerator",
        parameters = {
            @Parameter(name="initial_value", value = "1"),
            @Parameter(name="table_name", value = "hibernate_sequences")
        }
    )
private Long id;

Oh, I should have noted that I had to upgrade to 3.2.3 (actually, I upgraded to 3.2.6) to take advantage of the enhanced TableGenerator.
