It took 2 weeks and 2 days to get the result.
1. I did go through PetStore but cannot say I followed the same design. Yes, I used the command pattern.

2. Yes, I updated the multiplicity in the BDOM. My segment could have mutiple flights.

3. I took three weeks to complete the assignment, more hours on the weekends. I would have like to spend more time but rushed through to finish before going on my vacation.

Good luck!

Just saw the result. Don't understand why I lost in the component diagram.

Thank you to everybody that contributed to this forum.
Is it necessary to use the social security number for the jar file name if you are in the US?
Jose, I have been reading this book but it does not explain my question. It only talks about the Front Controller delegating to the Application Controller and then the application controller forwarding to the View. But I think in my case the client calls the JSP i.e. when a certain request is sent. In my sequence diagram, I was representing it as the Client sending a request to the JSP. Now I think the client sends the request to the FrontController and it in turn sends it to a response JSP. So there would be no request JSPs!!! Is this correct?
I am getting confused with the front controller and application controller patterns. If the client clicks on a page to send a request, is it

client-->Jsp-->frontcontroller-->applicationController-->businessDelegate

or

client-->frontcontroller-->jsp-->applicationController-->businessDelegate

I guess the front controller decides what jsp can process the request parameters and the application controller decides what command to use. But who redirects to the next page?
Thank you Jose. I didn't know you could use MDB for synchronous communication. So it will be asynchronous. David, I am using it for email.
If we use a message driven bean, how do we show it in the sequence diagram since it only listens for messages and is not directly invoked by any class?
Thank you, Giri. But my question is how do you look up any object you stored earlier i.e. what parameters would you pass to the SFSB? Take the example of a shopping cart. If the user hasn't logged in and adds something to the cart, how would I retrieve the information from the cart? I guess my question is more on the lines of how to use a stateful session bean. For example, if I used the SFSB to store my session data( i.e. flights in this case), how would I retrieve that information without the handle for the SFSB? So I would have to store the SFSB handle in my HttpSession! Is this correct since I wanted to avoid using HTTPSession so the swing client can also use the SFSB?

I am confused about where to store login credentials if I use a stateful session bean to store session data. To retrieve anything from the SFSB, what would be the key? In most applications I've worked on the user Id is stored in the HTTPSession and is propogated to the EJB layer when required.
I am adding the stereotype <<System>> and the use case name. But since I use together, it shows a rectangle unless I have the stereotype <<actor>>.
This is the way I understand it. It doesn't matter if the usecase has two actors. You can always add a note that explains the actors. As for the pricing, it is definitely invoked by the prepare itinerary use case.
Congratulations!! If you used an application controller, did you actually show all those related classes in the sequence diagram? Thank you.
I am confused about the number of times the pricing usecase is called since the system initially prices the flights without a seat. How would it know what price to calculate since the user hasn't selected a seat yet?
