I am glad I finally cleared SCEA, although i lost 15 marks in my component diagram. I kinda know i will lose marks in that area as I am not familiar with the component diagram and I am not sure wat to include.

Good luck to those who are waiting for their results.
Time to celebrate....
Hi

Strange that the email from prometric asked me to check http://i7lp.integral7.com/sun for updates.

But Accinelli is right, i just checked the site https://www.certmanager.net/sun_assignment/, and my results have appeared, but it is only for part II (what happened to my part III?)

thank god I passed with 82%.

When did you take your part III exam? I took mine on 25 Oct, and I am also waiting....

Hi

I am doing part II and III now. Currently having some doubts on how to present the entity bean and DAO in my sequence diagram.

I have decided to use BMP + DAO + VO, after reading some of the earlier threads. Problem is

a) I am not sure whether I should show the entity bean (BMP) inside my sequence diagram. Should i just show DAO classes without entity bean to make it technology independent ?

b) And having 1 BMP for each entity is not coarse-grained, so i am thinking of using composite entity to make it more coarse-grained and reduce number of network calls. If i were to show BMP in seq diagram, then should I show the interaction of the composite BMP (eg. CustomerBMP interacting with CustomerDAO, CreditCardDAO and AddressDAO?)

c) if i dont show entity bean (BMP) in my seq diagram, i also should not be showing it in my class diagram, that means component diagram is the only place i should show my entity beans ?

Any advice is much appreciated !!

Thanks & rgds

Hi

So if i intend to use DAO inside my sequence diagram, I need only show the DAO and not EJB ? Cos the DAO encapsulate the db access logic, and we are free to use EJB or hibernate in our implementation.

The assignment says it has to be J2EE compliant, but right now my sequence diagram only shows JSP/servlet, session beans and DAO. No Entity Beans yet, so i am not sure whether this will be truly J2EE compliant.

Appreciate any advice.

Thanks & rgds

Hi

I am attempting the 2nd part of the assignment. I have a question regarding the EJB and DAO. From what i understand, DAO is a OO-pattern, so do we use DAO when we want a persistence layer without EJB and we write our own JDBC and sql code to access the database.

Or is entity bean still required ? then where does the DAO come in ?

Appreciate any clarification.

thanks & rgds
