[Glass] Zinc and REST on 3.1.0.X

[Ken Treis]

I've never used Zinc in GemStone without the Seaside adaptors, but it shouldn't be too difficult to get Zinc running. To see the basic pattern, look at the startSeaside30_Adaptor script (in $GEMSTONE/seaside/bin), WAGemStoneRunSeasideGems class>>startGemServerOn:, and the Zinc adaptor class.

You'll be launching a topaz process for every Zinc backend that you want to run, and within topaz you'll instantiate your Zinc server and start it. While it runs (in its own thread), you'll keep the main thread busy with an infinite loop.

You'll also need to manage transactions yourself, which can be a little tricky. The Seaside code uses a big lock to make sure that only one thread can be in a transaction at a time, since GemStone's transactions are per-session and not per-thread. This alone might argue for using Seaside-REST over Zinc-REST, but you know your project and your needs better than I do. :)
