Errai and Seam

[rkilcoyne]

Anyone successfully wire a Seam app to the Errai bus?

My ultimate goal is to be able to send messages down the Errai bus in response to server-side events generated by my Seam app. Seam has support for mixing Seam Components with Guice, but it required that you know the name of the Injector module beforehand. It appears that Errai dynamically creates the Injector modules on app start for each class annotated @Service. I haven't yet figured out how to get the name of the modules generated by Errai.

Any ideas/shared experiences would be much appreciated.

I know the team is looking at wiring CDI (Weld) and Errai, but not anything from the Seam 2 branch.  Is that something that will be useful?

[heiko.braun]

Rodney is right. Currently we only work on CDI (Weld) integration:

But it shouldn't be too difficult to do something similar for Seam.

[rkilcoyne]

Ah nice. This should do the trick! Thanks all for the pointers.

[heiko.braun]

Which means you are already using Weld?

[rkilcoyne]

Not quite yet. As good as it looks, I'm not sure about moving forward with developing using Weld on an M2 release.

Actually, I was going to post a question here to get some advice on when to move to j2ee 6. I'm on Seam 2.2.0 on JBoss5.1. What's your take on moving to Weld at this point in the 6-series release cycle? My production timeframe is sometime mid-Summer. The only migration work I see is moving my Gilead integration classes for Seam over to Weld -- which should be trivial.

This would be a much easier/cleaner effort if Seam 2.2 included a discovery and extension point as nice as Weld's... ;-) I'm really looking forward to Weld.

Jason explains the milestone system in a DZone interview - http://java.dzone.com/videos/jboss-as6-m1 - and from M1 of JBoss AS 6 Weld/CDI has been a complete, final "block" of the system. So I would say that part of JBoss AS 6 is ready for your app. Of course, if you are heavily using EJB 3.1 (for example) you should check how ready that bit is in the latest milestone :-)

6.0.0.M2 has support for EJB3.1 nointerface views and EJB3 war deployments http://community.jboss.org/wiki/EJB31inAS600M2.

Upcoming 6.0.0.M3 will have support for EJB3.1 singletons http://community.jboss.org/wiki/EJB31SingletonBeansinAS600M3

I've updated the weld-integration examples so they successfully deploy on JBoss6.0.0.M2:

Make sure to check the README.txt

Thanks Heiko. This sure would make a nice Seam 3 module ;-)
