如何将JavaEE后端与Play框架结合？

Question

I am creating a new web application where I am using JPA, EJB and all the goodnes from JavaEE. However, I have been doing some JSF in the past (yes the latest version) and I personally don't like that much. So I have been introduced to Play Framework which is pretty awesome from what I have read so far. Now I want to use the Java EE backend with the Play framework. How would you do that? In order to use EJBs etc you need a EJB container and all that is provided by servers such as Glassfish, JBoss etc and Play framework use Netty (if I am correct). So how would you make these technologies talk together? Webservice (REST), RMI...?

And would the performance/lag be very high? I will have both servers running on the same VPS.

Answer 1

If you are using Play 1.x (which I suspect that you would be since it sounds like you are looking to use Java, not Scala?), then you could use the Play Spring Module .

I have not personally used this module with Play, I have stuck with the out-of-the-box structure (which uses JPA, btw).

AFAIK, you'll have two options:

1. Use an embeddable EJB container and start it in the Play 2.0 Global.onStart() . It exists these kinds of containers for various Java EE servers ( JBoss , Glassfish etc...)
2. Use webservices served from your Java EE app, but it will add a new "layer", and it should be slower.
