Great job Yogaraj! Thanks for the tip you shared for all of us. I'm sure a lot will benefit from it! Again, congratulations!
Congratulations! Can you share some tips for those working on their certifcations right now?
Hi all,

May I know how to link uses cases in the sequence diagram? I'm aware of using frames, but is it important to be accurate on it's length (encompassing the different lifelines)? In the project assignment, how did you guys link the login use case? Is it sufficient to end up with a "login page"?

Hi Steve,

What UML tool did you use to include ref frames on your UML diagram? I can't seem to get my StarUML stimulus to connect to my ref frame.

Hi Kumar,

If your intention is to have a centralized controller for both your JSP and Swing client, you could have something like this...
Web:
JSP --> Servlet --> AppContoller --> ServiceLocator -->
Swing:
Swing Client --> GUIController --> AppController --> ServiceLocator -->

You could have your web and Swing presentation layers use the same AppController. Your servlet processes your HTTP input and your GUIController processes your Swing input.

I hope this makes sense.

Good luck!
Hi,

If you look at the basic flow of the Prepare Itinerary use case, the system prices the itinerary AFTER the customer selects seats and BEFORE the customer confirms the itinerary.

The Use Case diagram should give you a clue. Notice that the Price Itinerary is included in the Prepare Itinerary.

I hope that helps.

Ok, thanks for the response. my main question was - is it ok to show subsystems in a component diagram and is it ok to dissect the large component
diagram into smaller units for the SCEA exam....

Looks like I'm on on the 1st question


It's ok to show subsystems and dissect large components as long as your diagrams would not appear to be very confusing. You may also put additional explanations in your assumptions documents. Keep your component diagrams clear, concise, yet simple.

Still not understood ? Can you give a little bit more explanation?


Hi,

I'd like to share my thoughts on this.

I believe it would be more appropriate to link seats to an aircraft (equipment) than to a flight to provide better flexibility. An airline could upgrade its fleet but maintain the same flight number. For example, I have flight 5J803 that uses an Airbus A320 with a seating capacity of 180 seats. If I get a direct flight-seat relationship, I would have a seat number like 5J803-180. What if the airline switches to an Airbus A318 with a seating capacity of just 117 seats. Seat number 5J803-180 will obviously be invalid because there is no 180th seat on the new plane. Linking seats to a specific aircraft would ensure that your seat number would always be valid for a specific flight because it's dependency will be on the aircraft rather than the flight.

I hope this makes some sense.
Hi Alok,

Thanks for posting tips on your exam experience. I'm sure a lot will benefit from them Good luck in your career!
Try removing your CLASSPATH definition. Just maintain the JAVA_HOME and include it in the PATH. Let me know if that works.

Good luck!

Are you getting the errors for java.net.Authenticator class only? It's found in rt.jar, make sure it's in your classpath.

Can you post the command you issued in compiling your class? Or could you post your classpath as well? It would be helpful if we see how you defined your classpath.

The way EJB is implemented may differ from one server vendor to another. I think the authors' intention not to include a lot of details on server software is for you to focus on the EJB specification itself.

The exam does not include any vendor-specific question. The best resource for the software reference might be the server documentation itself and not the Head First book.

Good luck on your review!
Congratulations!

Are there any tips and advice you wish to share to everyone? I'm sure it would be very helpful to those reviewing right now.
