Finally it's over!
I've just seen in CertManager that I've passed my part II with the following results:
Score: 90%
Class diagram: 44/44
Component diagram: 36/44
Sequence diagram: 10/12

However Sun certification database still shows my part 2 as pending. Is this just a matter of time?

Also, how long does it take to get the certificate package from Sun by mail?

Thanks!

Alec

I uploaded my part 2 on Oct 5 and took my part3 next day. The CertManager was updated Oct 31. So it's about 4 weeks.
Do you know when I can expect the paper certificate?

Trying to avoid saying too much:
I used Fast Lane Reader pattern with assumption that some external process (sort of a nightly job) would update the flight information in the database at a predefined interval.

Depends on where you are and when they mail out the certificate, honestly. For me (in Maryland, USA), it takes about five business days for certificates to arrive.

Congrats on passing - that's wonderful news.

Thanks much - hope all those months were not spent in vain.
By the way, when you found your part 2 status became "passed" in CertManager, was your certification status on the certification database changed to passed at the same time? For me it still shows pending, though it's been already 5 days sin ceCertManager status turned to "passed"...
I'm not sure if I need to worry or this is just a matter of time.

Thanks!

Alec

Congrats Alec !!

Its a great score.Could u pls tell me how did u represent the 'composite entity' design pattern both in component diagram and the sequence diagram.

Thanks

I haven't explicitly used this pattern. Though having analyzed the business object model I did combine some business entities into one component in my component diagram.

Thanks Alec,

Could you pls answer a few more questions

1.In which of the two diagrams(component or sequence) did you show the DTOs.

Cade's component diagram doesn't show any DTOs.

2.How did you do the state management for the Java client. Did you use an SFSB or client side management ?
Could you also refer some sources where I can find examples showing state management using java client or SFSBs.

3.In the Component Diagrams given in Mark Cade only the 'dependency' relationship between
various components is shown.In case we need to show the 'generalization'(inheritance) or
'realization' relationships then how do we show them ?

In case we dont show these relationships in the component diagram, then in which diagram
do we show them ?

Note - In the above I am referring to the components and not the various classes in
the 'class diagram'.

Thanks In Advance
Pankaj

I'll try!
By the way, do you know if there's a topic watch feature at Javaranch? On other forums I can mark a topic as "watched" and get e-mails every time there's a new post in the topic.

Hi Pankaj,

1.In which of the two diagrams(component or sequence) did you show the DTOs.

This question deals with the level of details. I would answer as follows:
a) I did design my solution keeping in mind that DTOs will be used to transfer data between components.
b) I haven't explicitly shown DTOs on any diagram as DTOs appeared to be below the detail level of my diagrams. You can show them or not, on component or sequence diagram - it's all up to you. Any choice would be correct provided that you use them appropriately.
Another point to meditate on: you need to avoid creating extremely complex diagrams. YOur diagrams should be easy to read. If you feel you really need to put too many details, you might consider moving a component to a separate diagram that would depict its internals.

2.How did you do the state management for the Java client. Did you use an SFSB or client side management ?

I used client-side session management. But it doens't mean SFSB is a wrong choice. Both options have pros and cons, be prepared to defend your choice. Part 3 may well have questions similar to this one.

Could you also refer some sources where I can find examples showing state management using java client or SFSBs.

Google will be the answer, my friend. There's just a lot of resources and I wouldn't like to flood the topic.

3.In the Component Diagrams given in Mark Cade only the 'dependency' relationship between
various components is shown.In case we need to show the 'generalization'(inheritance) or
'realization' relationships then how do we show them ?

I personally think that dependencies should be depicted in the class diagram. Component diagram is a higher level view of the architecture. Though in some cases you can show dependencies between classes within component but this should be an exception to the rule.

Hope this helps!
