Should I use EJB3 or Spring for my business layer?

Question

My team is developing a new service oriented product with a web front-end. In discussions about what technologies we will use we have settled on running a JBoss application

Answer 1

Another thing in favor of spring is that most of the other tools / frameworks out there have better support for integration with spring, most of them use spring internally as well (e.g. activemq, camel, CXF etc).

It is also more mature and there are a lot more resources (books, articles, best practices etc) & experienced developers available than for EJB3.

Answer 2

Regarding your question:

What are the arguments for or against EJB3 vs Spring?

I suggest reading the response from the experts: A RESPONSE TO: EJB 3 AND SPRING COMPARATIVE ANALYSIS by Mark Fisher. Read the comments to find Reza Rahman's remarks (EJB 3.0).

Answer 3

i have used a very similar architecture in the past. Spring + Java 1.5 + Actionscript 2/3 when combined with Flex Data Services made it all very easy (and fun!) to code. though, a Flex front end means you need adequately powerful client machines.
