  • J2EE vs J2SE

    Hi, I've done a little research on both of these and still can't get a grip on their difference. Please explain how to get these too. Like the area of download. Because I'm not sure if J2EE and J2SE are both included in the Java Runtime Environment download. One more thing, is Java Runtime Environment the virtual machine, or what is Java Runtime exactly.

      From the Faqs: http://java.sun.com/javaee/overview/faq/javaee_faq.jsp

      Q: Who needs the Java EE platform?

      ISVs need the Java EE platform because it gives them a blueprint for providing a complete enterprise computing solution on the Java platform. Enterprise developers need Java EE because writing distributed business applications is hard, and they need a high-productivity solution that allows them to focus only on writing their business logic and having a full range of enterprise-class services to rely on, like transactional distributed objects, message oriented middleware, and naming and directory services.
      Q: Where can I get more information about the Java EE platform?

      For more information about the Java EE platform and how to get the specification, see http://java.sun.com/javaee/.
      Wiki: http://en.wikipedia.org/wiki/Java_Pl...rprise_Edition

      Following the above links should give you a decent idea about what Enterprise Edition is.

      If your application doesn't need any of the features of EE then I say you should stay with SE. I personally haven't used J2EE.

      Java SE: http://java.sun.com/javase/downloads/index.jsp
      Java EE: http://java.sun.com/javaee/downloads/index.jsp

      Again, use Standard Edition unless you know for sure that you need Enterprise Edition.

        J2SE is the java runtime. In a nutshell J2EE build on that and provides extra functionality to build web and enterprise applications. However there are many interfaces in the J2EE spec that are implemented by a J2EE containers which will runs you applications.

          running j2SE in web??

          can you run a J2SE applet on the web or do you need to use j2EE 5 and does J2EE use the same language code as J2SE or is it slightly different like C++ to C or is it majorly different and is there a seperate runtime environment to download if you use J2EE and If I have J2SE runtime environment installed is the only thing I need to install for J2EE is the J2EE SDK or do I need another runtime environment. Which J2EE installation would be best, there are like 6 options for installation. Thanks
