    Hello guys

    i have a simple doubt

    sun release the EJB 3.0,
    well and Spring is powerful of course and i am happy with it
    but......

    any experience and suggestion are appreciate

    thanks for advanced

    J2EE isn't EJB, so first of all do you need EJB? If you are happy with Spring, do you need anything else? I think it's always good to know what's out there, so it would be worth spending time understanding that. But if you don't need it, why use it.

      While I agree mostly with what Karl is saying, but I would like to keep an eye on the developments going on in the standardization process. After all EJB 3.0 is a standard and JSR 299 (WebBeans) is an important development going on. Possibly we will have things like Seam and Guice plugged in to this stack. The main advantage with this stack will be its compliance to standards, which may be an important point to consider. I have been using Spring, and I love Spring, but possibly it makes sense to keep an eye on these developments in the EJB world ..

        Indeed, I try and read up on new developments as much as I can. Personally, I just find there aren't enough hours in the day. I try to get an understanding of what is out there and what is going on, and focus more on getting better at the technologies I am using. Hopefully by the time I get round to using them, they might have bedded in a little .

          From my brief experience noodling with EJB 3 and Java EE 5, I can say that they are similar to Hibernate and Spring, but that Hibernate and Spring are still good for many applications. Java EE 5 introduces annotation-based dependency injection, which is *great* compared to the deployment descriptor mess of earlier Java EE apps. EJB 3 / JPA is really nice, but it is missing some critical features vs. Hibernate that make it hard to model very complex data structures. I think both should be interesting to watch in the (near) future. I can definitely say that they make getting simple Java EE apps started quickly much easier than it used to be.

            good point, but how i see that Spring support or can work together with ejb, so why this reason?, only migrations purposes?

            mmmm, so Spring avoid or not use some standars?, which ones?

            i am agree, the point is that exists somemany options out there and it would be cumbersome to us, trying to learn these options, of couse Spring is very cool, but happnes when we take some bad option?

            yes of course, both are based in Spring nd Hibernate
            the problem of Sun that never listen its comunity,
            reason important of the creation of .Net
            thats other history

              It all depends on what you want out of this and what you have to work with. Some companies like standards. Would you use Hibernate or JPA? Others just want the job done, so just use whatever works. As I said previously, I learn about the tools I'm using and also learn about tools to might help me.

                I wonder why you talk about either Spring or standards

                  Not sure if that was related to my comment. I put standards in italics because I don't really buy into the word. Standards from an EJB, JPA, etc... perspective. Standards from the our company will always use XYZ framework to do this perspective. I'm not suggesting you use Spring or standards, they aren't mutually exclusive.

                    This whole thread from the start seemed to be about either or for me.

                      The entire Web Beans (JSR-299) proposal seems to an either or with Spring. It is going to be heavily influenced by Guice, Seam, Shale etc. and will be totally based on EJB 3.x technology.

                      Cheers.
