Java EE 6 Platform Draft Published 74

Posted by Soulskill from the rather-drafty dept.
synodinos writes "The public draft of the Java EE 6 Platform specification has been published and will remain open for public review and feedback until the 23rd of Feb, 2009. Perhaps the most notable part of this delayed draft is the Web Profile, which is first profile in the history of the Java EE platform. The draft is available for download and contains both the Java EE 6 Spec and the Web Profile Spec. There is a poll running at java.net regarding what the community thinks about the new spec. Although participation is yet rather small the results tend to show that the released draft did not cause any excitement."

    I'll settle for 5 at this point. My shop is still using 1.4.2; it feels like I should be writing code on stone tablets! I suspect this is the case in any number of Java shops and it just reinforces the idea that Java is going to become the new COBOL. There is so much "legacy" code out there right now, and because of the inconsistencies between versions I can't see it going away any time soon.

    • Just because your company stays in the stone age doesn't mean everyone else is.

      It's unfortunate but it may be best for your company if stability means more than new features an it's that way with any language.

      Java is much much more than the new COBOL. COBOL will be dwarfed by Java when it comes to legacy. Think of it: COBOL was never the language used for the very first programming courses. While Java has the particularity to be both widely used in academic circles and in the Real World [TM].

    I've been leading the development of Java applications for around 8 years. On that journey, I have used fewer and fewer features of it with each succesive project.

    Nowadays, it seems that specs are a kind of summary of what has been learned from the frameworks which were created in the trenches by people that actually needed to deliver.

    My latest project, which has been in development for around 1 year, delivers as a plain web application, and uses Hibernate, Google Guice, AspectJ and Echo3.

    It's wonderful.

    Sun don't have the capability, and I'm not sure that anyone has, to provide a full and relevant specification that will allow code to be developed that will run on any application server from any vendor.

    Instead, choose your implementations and go back to good old OO basics to design interfaces behind which to hide those implementation choices. You don't need Sun to do that for you.

    • Sun don't have the capability, and I'm not sure that anyone has, to provide a full and relevant specification that will allow code to be developed that will run on any application server from any vendor.

      • Ignoring your grammar difficulty, the majority of useful applications out there require a non-embedded database solution...therefore, some configuration is mandatory, for pretty much any application on any platform. To all of you complainers, I work on an application which deploys successfully to Jetty, Tomcat, JBoss 4.2, and Glassfish (as just the ones I've tested). In fact, I test it on all 4 platforms on a regular basis. Sorry, but it works perfectly for me.

          That's nice. So it runs in the web container. By the way: Which web container do JBoss and Glassfish use? So it's only two different runtimes, isn't it. The compatibility nightmares come when you integrate your Java application in a typical enterprise setup. With SAP, CICS or IMS/DC, FileNet, ICR/OCR Servers, legacy C and C++ applications, .Net, WebSphere MQ and lots other stuff.

      I've never seen a serious commercial product shipped independently of an application server. I've always though of an application server to be more of a framework. As a product author/vendor, I make choices about which application server best serves my product. Then I build around it. When I sell to end users, I either enter into some kind of licensing/support agreement with the application vendor, or I require the end user to purchase licenses and support themselves.

      The spec exists so that developers can write components that can interoperate with various application servers. For example, I can write a data connector for a proprietary mainframe application and use JCA to include that in distributed XA transactions. That resource adaptor can be used on virtually any application server, but the way it is deployed and configured will differ.

      Or I might write a custom JAAS LoginModule to support some kind of proprietary authentication requirements. Again, the ability to integrate into an application server is undisputed, thanks to the specifications, but the mechanisms by which it is integrated is left to the implementor.

      To support full drop-in interoperability, Sun would have to control all of the details of deployment and configuration, and then there goes competition. Everyone would just grab a copy Glassfish and rebrand it, because how then would you innovate?

      As a developer I'm glad that there are differences in application servers. The various classloading strategies, configuration interfaces, and monitoring tools ensure healthy competition and innovation. And if something becomes ubiquitous (or problematic enough) then it gets added to the standard. (EJB3 is largely Spring+Hibernate, standardized, and Seam+Facelets is on its way to standardization through JSF 2 and WebObjects.)

      One last thing. I've worked in shops that ran Tomcat plus a few third party libs (i.e. Struts and Hibernate), and I've worked in shops that have used the full JEE stack. In the former, we had infrequent but persistent problems with transactions (lost updates, etc.) that required implementing a lot of proprietary transaction management code. Using the full JEE stack you have things like JTA and JPA that manage locking for you, which can be painful if you don't know what you're doing. But it forces you to deal with real issues rather than pretending they don't exist, which is a must for true enterprise applications. The same can be said for resource pooling, security, managing web sessions and conversations, and many other issues.

      • I've never seen a serious commercial product shipped independently of an application server.

        It depends on definition of 'serious' of course, but I was working for a company producing software for airline operations (briefing/loading, no booking nor avionics/realtime). We had number of clients, including some really big names in Europe. Software was written in J2EE and it was used on 2 different application servers, on 2 different databases (3 combinations in total) - only because companies we were supporting were mostly standarized on Websphere, so there was no need to test it on more. There is NO

      • Can you give us more detail on the "shops that ran Tomcat .. had infrequent but persistent problems with transactions (lost updates, etc.)"?

        • The shops that ran Tomcat generally used JDBC or some in-house persistence framework. In either case, there were no facilities for dirty checking or optimistic locking. So if user A loads an object into his session and modifies it; and user B loads the same object into her session and modifies it, then the changes made by whomever commits first are lost. Small shops generally ignore this problem as it happens infrequently enough to warrant serious development time, and usually end users catch the error a

        To be a little pedantic: the name was Web Beans; WebObjects is Apple's framework. JSR-299 now has the oh so sexy name: Java Contexts and Dependency Injection [relation.to].

    • Well, I've been leading development of various applications done mostly in Java for the past 11 years, and I wouldn't use Hibernate, Google Guice, AspectJ and Echo3 in any of them, though sometimes we end up using some of it. I often end up removing these and other technologies from the messy projects that are passed to me after the original team is done f.cking around with them.

    It might be slow but it has been very successful. Sure many specs never saw the light of day. That is to be expected from every committee.

    Like it or not, Java is king on the enterprise server-side. J2EE sucked at the beginning but successive versions addressed many issues required by the enterprise. Persistence (Hibernate, Toplink), transactions and messaging (JMS) and the many available and free implementations. Thank you Sun for sticking with the JCP. Standards are wonderful.

    We have an ASP platform built on J2EE 5.0 handling hundreds of millions of transactions a day all on a free stack thanks for the JCP and Linux.
