Enterprise Application

Question

I am thinking about a platform for study application (it is team work). I mean standard Java EE 5 (or maybe try raw Java EE 6) and Spring. What is your choose? (I don't mean Spring MVC but Spring Beans and EJB 3.0)

Also I would like to know what app server you use? (now I use GlassFish v2)

Answer 1

이렇게하면 목록 항목의 끊김 권한이 필요합니다.항목을 생성 한 사용자와 항목에 할당 된 사용자는 Contribute 권한을 주어야하며 휴식을 view 권한을 얻을 수 있습니다.그러나이 방식으로 목록 항목에 대한 사용 권한이 손상된 경우 성능이 빠르게 열화됩니다.

Answer 2

As duffymo says, look at Spring without EJBs. Spring is very powerful, regardless of how much/little you use. I don't know of anyone using EJBs now. Having said that, EJBs have changed dramatically over the years, and now resemble ORMs such as Hibernate (which is worth checking out in itself).

For app servers, check out JBoss. It's free/open-source, and you can choose the web component between Tomcat and Jetty. It's JMX backbone allows you to easily monitor its state and to integrate your own JMX beans into that backbone (if you're using Spring, you can JMX-enable any bean with a simple configuration).

Answer 3

If you want Java EE 6 then the choice appears to be either Glassfish 3 or the beta of JBoss 6. As some of the others have said, I also prefer Spring to Java EE's EJBs.

I don't see much point in looking at Java EE 5, unless you think you will be working with it in the future (possible as some companies are conservative in using newer versions of technology).
