Hi guys,

In order to support runtime increased O/R mapping. I have to rebuild SessionFactory without restart my application.
Could I keep cache after rebuilding SessionFactory?

you can't.

an alternative would be to make a copy of the cache...
or maybe a staging table that you can write to just before you rebuild your session factory. then at least you have a snapshot of that data

can I ask why you are rebuilding the SessionFactory during runtime?

cheers,

pali

I want change or add O/R mapping runtime, that's why I have to rebuild session factory.

My first target is: supports uer runtime define some customized fields.
My second target is: user is able to extend pojo runtime.
Both targets request dynamic mapping.
