getThreadObjectContext

[Marek Šabo <ms...@buk.cvut.cz>]

Hi all,

just wanted to ask you how scoped ObjectContext does method 
getThreadObjectContext() return?
I mean javadoc says it's bound to current thread, and there is a new 
thread started during each request so is it "RequestScoped"? Or is it a 
global object that gets bound to the thread when new request arrives 
("SessionScoped")?
Friend of mine told me that he was only using this method for obtaining 
OC and that it remembered fk dependency issues between independent 
request so I'd go for "SessionScoped".

Regards,

Hi Marek,

I assume you are talking about using
BaseContex.getThreadObjectContext() along with the
WebApplicationContextFilter described here:

http://cayenne.apache.org/doc30/web-applications.html

The scope of those ObjectContexts are indeed session-based for the web
application.  Each user gets a unique one, but the same ObjectContext
is re-attached each request/response cycle for the user, so
objects/etc in the ObjectContext stay around across requests.

mrg
