I guess that's a bit premature. Let's figure out if there is a problem
before opening a Jira. "Jiras" are "tasks", i.e. specific action
items. So I'd rather we come to some consensus on what needs to be
done firs, and then Jira action items.

Multiple Transactions: Migrate from Singleton pattern
-----------------------------------------------------
Key: CAY-1322
URL: https://issues.apache.org/jira/browse/CAY-1322
Project: Cayenne
Issue Type: New Feature
Components: Cayenne Core Library
Reporter: Evgeny Ryabitskiy
Fix For: 3.1M1
Duplication from Dev-list:
So.. I have several modules, each has own DomainConfig file and
connection to it's DataBase. Sometimes there can be used different DB
servers and even different DB types (usually it's Oracle and MS SQL,
sometimes Sybase).
Singletons:
1) Configuration.getSharedConfiguration()
This problem is solved:
DefaultConfiguration conf = new DefaultConfiguration("module1-
cayenne.xml");
conf .initialize;
conf.getDomain();
//spend some time to find solution... everywhere examples with
SharedConfiguration
2)DataContext.getThreadLocal()
Solved by own ThreadLocal for each module. (modules can work in one
thread)
//also spend some time
3)Transaction.getThreadTransaction()
this is killing one!!!
using of own ThreadLocal doesn't help.
It's hard-coded in performing Query to use this singleton
Transaction.getThreadTransaction()
And that is really huge problem for me.
So me suggestion is to move this ThreadLocal to DataDomain. Still can
use singleton API for standalone applications.
Also we can move DataContext to DataDomain.
