[jboss-as7-dev] Intended deployemnt behavior?

[Bob McWhirter]

Jim and I were discussing exploded deployments in #torquebox, and realized...

TorqueBox pretty much only uses exploded deployments, but we do it slightly differently, and avoid copying tons of files around and dealing with partial-copies and non-atomic things.

Our exploded apps live wherever the user wants them to live.  Anywhere on disk.

Into the deployments/ directory, we scribble a simple text file, which is basically a poor-man's symlink, plus other information used by TorqueBox.

But generally, it contains a path-to-the-exploded-app.

A deployer picks it up, and adjusts the DEPLOYMENT_ROOT (or whatnot) to point to the actual exploded application elsewhere on disk.

>From the AS perspective, we're deploy 1 small text file, at least initially.  But then it magically becomes an exploded directory full of loose files.

Dunno if it'd help, but generally supporting a deployments/myapp.link deployment, where the myapp.link file is just a text file containing only and exactly the path to an exploded application, might be useful.
