Lin-
I think Albert's above statement make perfect sence. How do u handle non-webclient? Especially if you want to maintain client state in a modular way for both Web and non-web client?


I was searching the forum, but not able to find these topics. Can SCEA's help ?

Albert-
Thank you for ur prompt answer. Another thing that came to my mind.

Do we really need entity beans here, why can't we live with just session beans like CADE's book shows

Do we really need to follow EJB centric design for the assignment? Why can't consider Webcentric? Why I thought of this is because of following

The application performs update operations (transactions)
-when a user creates a new user account or when a user creates a new sign on.
-when a user accepts the itinerary and Pay

It looks like, the application's transactional model is a simple model, as it only performs transactions to a single database. There are no distributed transactions across multiple databases.

In this case do we need EJB's ?

Please advice

thanks in advance

Hi-
This is my thoughts. Take this example. I am travelling from Indiana to Lasvegas (roundtrip)

The flight details are

IND->ATLANTA-LASVEGAS (TO)
LASVEGAS->ATLANTA->IND(BACK)

For this roundtrip there is 2 segments , and each segment has multilple "legs" or layover. If you think in this way the solution can be find.

What say?

In petstore implementation There is

AccountEJB-(Entity Bean)
CustomerEJB-(Session Bean)

What is my understanding is that AccountEJB is for creating an account and CustomerEJB is maintaining the current logged in user details.

What I confused with is that both has methods to create customer ie.
AccountEJB.ejbCreate() & CustomerEJB.createAccount()

Any idea why it has been done like this?

Thanks in advance

Hi-
Thanks for ur reply. I was going through Cade's book. In the class diagram, attributes are not shown, mentioning that it will be done by developers at the time of detailed design.

is that what everybody following

Thanks

In many thread I have gone through (especially the one Parag wrote), I saw the class diagram only depict business objects. What I understood here is that

-No technology related classes (servlet,jsp,ejb)
-No pattern related classes
-Only pure business (domain classes)

But I certain threads I saw the classdiagrams are having around 20 classes. Do we have that much domain objects/or I am I missing.

I apologize for the wrong posting.

Hi Parag-
I am a new entry into this group. Got a question
In the class diagram, you mentioned that techonolagy independent. As I understand u didn't specify the ejb's or servlets . But u might have specified classes like Frontcontroller,Business delegate etc? I mean pattern specific classes?

Thanks in advance

I am new to this group. Recently passed Part1 with 92% (definitely I missed this group, used whizlabs material). I have a question regarding Paper2 so called topic between segment and flight. I actually try to do a mapping using recent flight booking I have done(the values are not actual). here it is

I am travelling from cincinnati (USA) to Mumbai. below is the itinerary I got



To Bombay(mumbai)-india
-------------------------------
I have 2 stop over
1)cincinnati to Chicago -flight 1
2)chicago to zurich - flight 2
3)zurich to mumbai -flight 3


From Bombay(mumbai)-india
-------------------------------
2 stop over
1)Mumbai to Zurich ->Flight 1
2)Zurich to chicago->flight 2
3)chicago-cincinnati->flight 3

From all these I came to a conclusion

Itinerary has multiple segements (1. cinci->mumbai 2. mumbai-cinci)
segment can have multiple legs
each leg can have different flights

will it work?
