Using OJB in a servlet container

[Vincent Frison <tu...@ohmforce.com>]

Hi all, 

I cannot find info explaining the good way to use OJB in a servlet 
environnement. A first basic question could be : can an unique broker instance 
stands during all the app/servlet life cycle (i.e. the broker is instancied 
once at servlet init) or a new broker should be instancied on each new HTTP 
session, or even on each HTTP request (reducing caching benefits I guess)? 

Thanks a lot.. 

PS: I had some difficulties to post to this ML, I'm sorry if this mail is 
finally posted many times..

A broker should be treated much like a JDBC connection. Obtain, use, 
close.


I would definitely *not* put an open broker in the session or servlet 
context. Caching works across brokers (depending on the cache 
implementation used).
