Modules, Endpoints, SQL, GCS, new Channel impl, … aka new CapeDwarf 1.0.0.Beta6

Posted by Ales Justin on Sep 11, 2013 announcement release

As you can see from the title, and from a bit late release, we’ve again been very busy.

Let’s just go over all new features.

Modules

Modules spec

There is a bit of limitation on our end here, as there is no (easy / nice) dynamic way (to my knowledge) to scale up / down virtual servers (at runtime during deployment phase) in JBossWeb that comes with JBossAS7 (which is what we use). In order to use Modules with CapeDwarf, you must use “standalone-capedwarf-modules.xml” configuration when you startup CapeDwarf AS instance.

You must also configure the number of virtual servers to match your application’s modularization. See web subsystem configuration in “standalone-capedwarf-modules.xml” for more details.

(or simply ping me for any Modules questions - via forums, email, Twitter or Freenode IRC #capedwarf)

Endpoints

Endpoints spec

We’ve managed to map GAE’s Endpoints annotations to JAXRS/RestEasy annotations, and we also support custom serialization.

In our case / implementation we only need .api files as markers, and not to read any information from it — you can have a single .api dummy file if you like.

SQL

SQL was of course supported out-of-the-box for us. We we just had to hack GAE’s Driver class to connect against selected DataSource:

GCS

FileService is being deprecated in favor of Google Cloud Storage (GCS) API. At the moment dev / local implementation of the GCS client library still goes against FileService implementation, so supporting this was easy, as we already fully implemented FileService API.
