Jaime Freire wrote:Hi All!!

Well, this is my experience; I took this exam yesterday; 185 questions and 5 hours of which I used everything but 10 minutes. I'm getting the results in 6-8 weeks. The test was similar to SCBCD 5 but without JPA questions and a little bit of the new features like the @Asynchronous annotation; @Singleton beans questions; different profiles...

It was way too long and deffinitely the little price (50 CHF) is not worth the time and having to wait that long for the results.

Apart from that there's almost no documentation and I had to prepare for the new questions reading articles like this: http://www.theserverside.com/news/1363656/New-Features-in-EJB-31

Cheers!



Thanks for sharing your experience!
Putting the discussion about a payed beta aside... I think the update ist quite good. Reflecting the new EJB specification JPA has been taken out of the exam. I think Oracle will release a new Java JPA Certification on its own.
I have a question abouth the PRG pattern. In an example PizzaOrder application I would use a POST request to order and redirect to a OrderView to view the order made. What I don't understand how to add request parameters to the GET request for the OrderView. The OrderView will need to have some kind of ID as a request parameter, so it knows which order to show. Where does the Browser get this ID from to send the appropriate GET request?

Please give pointers to study guide / material if any.


Thanks in advance



I have passed this test recently. You don't need to buy a book. Have a look at the site from IBM:

http://www-03.ibm.com/certify/tests/edu669.shtml

Read the IBM SOA Whitepaper and Chapter 1 of Websphere Service Registry and Repository. That is all you need to know for the exam.


First your list must be available to your JSP. You could put the list into an appropriate scope as an attribute.
Then your JSP needs to display the values. First thing that comes into my mind is using EL with the [] operator.

how to communicate between 2 servlets which are present in two different web applications?

case1: two web applications are deployed in the same server (for example tomcat)



You can get the ServletContext of another application running in the same server using getContext(String appUrl):

Kalabaw,

I played with your code, so the print statements give a more visual expression. Change the level variable to make deeper recursions.


Which produces following output:

Andrew,

it is hard to help you, because from your example I can't follow what you try to accomplish.

You might want to look at the continue or break statements, which let you exit the current iteration or the whole loop itself. The following link also explains labeled and unlabeled loops:

but what is the use of both interface and abstract classes..



When you create an interface, you're defining a contract for what a class can do, without saying how the class will do it. It is up the the developer implementing the interface, how the class runs internally.

When you define an abstract class, you still defining a contract, but you can implement the class partially. When you know that some methods will be the same for all subtypes, you can provide those in your abstract class.

And finally, classes can implement many interfaces, but only can extend one class.
