Recently, we've made some progress toward the promise of a polyglot application server. With the introduction of the Overlay project, it's now very easy to create a single app server capable of deploying both Ruby and Clojure (not to mention Java, of course) applications.
Laying TorqueBox over Immutant
$ lein immutant overlay torquebox
And voila, your Immutant is suddenly also a TorqueBox! Now we need to set up your environment for TorqueBox development.
$ export TORQUEBOX_HOME=$HOME/.lein/immutant/current $ export PATH=$TORQUEBOX_HOME/jruby/bin:$PATH
The TorqueBox distribution provides its own JRuby with the TorqueBox
gems pre-installed. You can now use the
torquebox command to deploy
your Ruby applications to your Immutant!
Laying Immutant over TorqueBox
If you'd rather use your own JRuby, and you've already installed the
torquebox-server gem, you can overlay the latest Immutant by cloning
the Overlay project locally, installing Leiningen and running the
$ lein run :overlay $(torquebox env TORQUEBOX_HOME) immutant
All that's left is to set
IMMUTANT_HOME and proceed as you normally would:
$ export IMMUTANT_HOME=$(torquebox env TORQUEBOX_HOME)
The Overlay project is capable of overlaying features from any JBoss AS7 distribution onto another one.
For your convenience, we've set up a job on our CI server to overlay the latest Immutant build atop the latest TorqueBox build whenever either is updated. So you can be on the bleeding edge of both projects by downloading and extracting this link:
IMMUTANT_HOME to the extracted
Get Your Polyglot On!
Your overlaid server may be started however you're comfortable: either using the Leiningen Immutant plugin, the TorqueBox command or even the standard JBoss commands. It will start up all the apps you've deployed to it, regardless of their language.
If you have any trouble at all, please drop by #torquebox or #immutant on freenode, and we'll get you going.
