Thanks Jeanne.

One more question, i did not use caching in my design at all. In Cade and Sheil sepcified caching as one way to improve performance.

If a question pops up in the exam, can i specify the same even though i did not use it the design ?

Please let me know, i am planning to take part 3 tomorrow

thanks
Hi All,

I think people who have cleared the exam might provide some insight.

I have read in the forum that there will be 8 essay question in Part 3 ? Is this true

Also what is the time duration to complete these 8 questions ? 120 minutes ?

Please help

thanks

Thanks Rishi.

I did the same., waiting for the response
Hi Li,

Thank you for your response. Did you get a confirmation number when you purchased the exam from http://ibt1.prometric.com ?

Please let me know

thanks
Hi All,

I have registered for Part 2 via Prometric in May 2011. I purchased the exam from ibt1.prometric.com.
I was able to download the assignment but i did not get any confirmation number for the exam i have purchased.
I have see the purchase on my credit card.

Now when i want to submit the assignment, oracle said they need a confirmation number to provide the voucher.

I have been calling prometric help for more than 10 days and they are just directing from one support team to other, but no real help.

I want to know if anyone who has purchased part 2 from prometric has the same issue (i.e not getting email confirmation about the purchase).

I have read a post on forum that some submitted the credit card statement and assigment screen shots and oracle sent them voucher. Please let me know if that is case.

I have reached to oracle at suncert_ww@oracle.com, but still waiting

Please Help as we are nearing the dead line

thank you very much
Hi,

I am using JMS queues and topic as part of the solution. Topics and Queues are part of the infrastructure, so no need to specify, right .

Please correct if i am wrong.

I do show the MDB and the helper classes

thanks

Thanks Jeanne.

In the component diagram, how should i represent them

I mean in the integration layer, just specify an instance of entity manager ( that is part of stateless session bean).

Or

There is no need to specify this at all.

Please advise
This topic has been discussed in the forum before. General consensus is to use http session. We should use Statefull bean only when it is absolutely necessary.

The main thing we are persisting is the shopping cart, with items and use of statefull in this scenario seems to be overkill

Hope this help

Hi,

I amusing EJB3 /JPA for the solution. I have stateless session beans as part of the solution which has Entity manager (used for all CRUD operations of database)

The business methods are within the stateless session bean, in short i don't have any separate DAO class. The entity manager is doing the abstraction.

How do i represent this in my Component diagram since entity manager is a EJB3 frame work class.

In the case example there are Inventory DAO, Pricing DAO and the sequence diagrams do show Entity Manager.

Should i give the DAO name and specify these are entity managers in brackets

Please advise


thanks








Hi,

I have 4 uses cases in my assignment. I will have sequence diagrams for each of them.

But there is also one feature (like inventory check) which is not specified as part of the use case in the assignment, should i include sequence diagram for inventory check too

Please advise

thanks
In the deployment diagram do we need to show the actual components (like JSP, JSF managed beans, StatelessSession beans) ?

I think in the deployment diagram we need to show physical deployments and artifacts.

Since components are inside artifacts, no need to show them

In the book by cade on page 175 it is not shown, but page 159 has it.

Please advise
I think you should use UML 2.0 syntax


http://www.ibm.com/developerworks/rational/library/3101.html

If you are using visualparadigm for the assignment you can select arrows for synchronous, asynchronous and return message.

thanks
