Hi Damien, thanks for your feedback :)

We’ll definitively try out the beta version and will probably use Glassfish since most devs in my company use it as the preferred development app. server.

> The WAR support really needs to come out of alpha

Next version will have “beta” status, as the plugin is deployed in “real life” (see http://factile.net/) and support all Play HTTP features (except WebSocket).
I prefer to go slowly, but with quality (with many integration tests).

I need Glassfish testers :)

> make it into the framework itself to provide more confidence/stability

First implementation of Play2War was coded to be delivered and integrated into Play core, not as an extension.
But Zenexity guys don’t want to work/accept contribution on WAR packaging now because of missing websocket feature in servlet containers.

It will, as soon as the servlet API makes it possible (3.1)

Indeed, the main issue is corporate acceptance, not the actual technical complications. The WAR support really needs to come out of alpha and make it into the framework itself to provide more confidence/stability and the chance for developers working within “strict” companies to convince their bosses that Play is a real option and that it will boost the productivity without compromising the installed platform.

I got to know Play about 1 year and fell in love with it. The absence of war deployment can be considered a drawback but it’s important to notice that play’s embedded server is jboss netty, the jboss server web layer, so I don’t think using play’s embedded server is any worse than using a regular jboss. On “escalation/redundancy” play is a stateless framework (at last it encourages you to code statelessly) and as long as you keep your code stateless “escalation/redundancy” shouldn’t be a problem, you just need a load balancer, actually it’s even easier to build a play cluster than any jee server cluster, much easier. On the “war deployment” problem, I face the very same problem. Here we use Glassfish and, though, I would like to deploy my play apps on play’s embedded server (cause it’s simpler), well I have to follow some rules. To deal with it you may try play2war plugin. It’s still alpha but, as I know, it’s working pretty well.

Thanks for the speedy reply, Ricardo. Looks like what I’ve seen elsewhere – Maven dependencies are ultimately handled by SBT.

Looking forward to your Eclipse followup!

Check out http://www.playframework.org/documentation/2.0.1/SBTDependencies for a reference on using a POM to declare Maven dependencies, though I think it’s best to use the default syntax if you are starting a project from scratch. On the details on how to do it you’ll have to refer to the SBT documentation.

Regarding the Eclipse integration I’ll try to write a follow-up with the steps, I already deleted my configuration (I use Netbeans myself).

Thank you for the writeup! I currently am evaluating whether or not to go play1 or play2, and clear-cut scenarios like this really help. Your comment about “transparent integration with Maven” is misleading, as it strongly implies an ability to specify dependencies via pom files, not just point to Maven Central. I’m also curious how you got auto-complete, etc, support from Eclipse for play2, as I was not able to find working instructions online. Thanks.

Thanks for the tip, already updated it :)
