[PJUG Javamail] PHP < -- > EJB?

[Steve Mayzak]

Richard,

If you are seriously considering Option 1, I would have a look at Grails or
Spring ROO.  Grails would allow you to take your existing PHP app and port
the pages to GSP's (similar to JSP) in a hurry.  I did this conversion for a
site with around 20-25 pages and it only took 2 days of half learning and
half doing the work.  Since Grails is built using Groovy which runs on Java,
you can always write things in Java if you don't want to use Groovy.

As for Spring ROO, it keeps you in java but still gives you that "convention
over configuration" model so you can get things up and running quickly.

However, both ROO and Grails are all about DDD so if your domain model is
already written, I am not sure how easy it will be to use either of these.
Conceptually I think it would work just fine, generating your controllers
and views from the Domain classes that is, but I haven't tried that in
practice with EJB3 Entities.

Just found this doing a quick google search

My 2 cents,
Steve Mayzak
