How to dynamically create a valid xml document from xml schema? I mean - xml schema is unknown at compile time, lets assume that we put file path or url of xml schema at runtime, and application creates valid xml document with some default values...

Previously for All there levels of SCEA the total cost is 200 + 250 + 150 == 600$

But now I guess we are looking at 300 + 375 + 300 == 975$..

Is it worth spending this much money beyond the effort & time for this certification ?



From the customer service perspective it is definitely not worth!

The costs increase gives you nothing but:
  • frustration - you can write email to sun, but they have better things to do than answering - several weeks of waiting is just the beginning
  • anger - you see P grade in sun_assignment, but nothing new in www.certmanager.net/sun - who was the architect of their systems?
  • hate - they force you to pay the money and they give a shit


  • Sun Microsystems is the worst company I have ever had to do with!
    Hi

    How long did you wait for the result?
    Lets assume, that we have a servlet with dependency injected ejb into instance field:


    Servlet and EJB run on different JVMs (and different machines).
    How it works?
    1. Injected ejb remains the same object per servlet lifetime or it works as a service locator every time servlet wants something from ejb?
    2. What if the injected ejb should be destroyed because of some exception - container injects new ejb automatically?

    I must consult the inventory system if an item is available. I don't know anything about the inventory system - if it is written in Java language, or further with EJBs, if it is accessible via some messaging system (to integrate via JMS), or even if it provides connector (to integrate via JCA).
    But it likely has an RDBMS to persist data.

    Can I assume that the inventory system has an RDBMS? And if integration directly with an RDBMS is a good decision?
    OK so have in my mind post about Part 2 assignment discussions, I am not quite sure if I can consult this...

    Lets say we have to ask existing inventory system about some information. There is nothing said about the system except, that we send some request data to and get some response data from it.

    Can I assume, that the system is connected with its RDBMS, and integrate on the data level - directly with that RDBMS, or this is too far simplification?
