I think this may be in response to a deleted post from me. To get Slick 2.0.1 working with Playframework 2.2.2 I had to install play-slick plugin and include the following in my datasource config:
db.default.slickdriver=com.typesafe.slick.driver.ms.SQLServerDriver
db.default.driver=net.sourceforge.jtds.jdbc.Driver
#rest of config
Where necessary in the I use play.api.db.slick.DB instead of play.api.db.DB, as well as the convenience class DBAction instead of Action in controller methods. As far as I can tell, Slick gets a connection from the pool managed by Play and associated libs and uses it normally.
The major stumbling blocks for me:
* Figuring out that I needed to configure both db.default.slickdriver AND db.default.driver
* Figuring out that play-slick is essentially required to conveniently integrate Slick 2.x with Play 2.2. (This should have been obvious I guess.)
