Hello, Hibernate team:

I am a newer to hibernate. My web project needs an O/R mapping tools. The project needs provide dynamic information to web user:

1). Web user sends its descriptions (Range from web user, may be one description or more) about their items to us.
2). So, we have to define tables for every customer to save it. We name table by customer name. All tables' main struture is same but different no. of description columns.

By searching in forum, Hibernate seems don't support dynamic mapping table and column or add/delete mapping at run time.

Do hibernate has a scuedule to support it?

This is actually quite easy to do in Hibernate by manipulating the Configuration object.

Thanks you very much.

This code is only workable that code changes mapping configuration before buildSessionFactory().

But it is impossible to build session factory every time when code changes the table name. buildSessionFactory() is slow and web page is used by many customers.

Would you please give me any idea about change mapping after buildSessionFactory()?

Danny Chen

That is not possible. There are very, very good reasons for this and it will never change.

Am I correct assuming that you can still build a new SessionFactory,
then replace your previous SessionFactory with it?

Or does that fail because of some internal bookkeeping in Hibernate?

(my assumptions is of course that sessions are short-lived)

yes of course you can build SessionFactorys however you like.
