Starting Hibernate

Hi,

My application have almost 200 persistent classes.
There is no application server on the environment.
SessionFactory is being built on a Singleton,
but it takes about 2 minutes.
The time to start the application is unacceptable.
I thought to create many SessionFactorys, each one with some persistent classes, but each SessionFactory will use one connection to database.

Does anybody have some suggestion ?

Why Hibernate don't save SessionFactory's Configurations
to posterior use ?

Thanks,

Douglas

Two minutes seems very long for 200 classes. Are these classes enormous?

We plan to make the Configuration object serializable to try and help improve startup times, we realize it is an issue.

I have about 4 seconds startup time for 50 medium-sized persistent classes on a cheap machine.

The classes are reasonably big.

Really serialization of the Configuration objects will be a great feature.

Do you have estimate of when this will be implemented ?

Thanks a lot.

We never commit to timeframes, but this would be a 2.2 feature, I doubt you will see it in the 2.1 branch.

Its probably not hard to implement it yourself, btw.

I have the same issue here.
To load 517 classes my notebook (HP nx9005) takes 6 minutes.
This serialization of the Configuration will be done in 2.2 ?
Are there a open issue to this on JIRA ?
