Hibernate startup time

Hey,

I am working with jboss 4.2 and hibernate 3.2. (JPA)

we need to work in rapid development cycle .
the problem is that we spent around 1.40 minutes on hibermate startup.
we have around 300 entites and a lot of name queries.

In development quick startup is more important for me from fast execution.

Can i configure some parameters that will cauesd to startup to be faster?
Can i for example set hibernate to not compile name queries on startup?

Thank you

Did you try the following hints:

jboss4.2 as server and hibernate as implementor.

i work with JPA annotation, so its not rellevant.

Can you cluster your entities in Modules, so each developer has only to configure the module(s) she is using, thus reducing the number of entities?

It's hard to believe that your 300 entities are all tied to one another with no independent subgraphs.

In this kind of system its very hard to isolate groups of entities.

Do you have any idea on how to reduce startup time ? (i am willing to pay in runtime)

Thank you

sub modules are the best approach unfortunately. This is a work we will probably do in Hibernate 4 but it requires a lot of rewriting and play with concurrency
