one class diagram without method and property, component diagram show controller component like controller and Stateless Bean and Statfull bean to controller the entity bean. sequence diagram show the messages to pass aroud the class objects. web front can be very simple, swing interface just one javaSW client, used J2EE design Pattern a lot.
In Sequence Diagram, for each diagram, the Action class is called From Controller several times. For eg. during initial submit, 2nd time - when user submit data again selecting the best flight etc.
Question, do you show "create" message to Action class multiple time or just the first time? Same thing for Service Locator locating EJB. Do you show that ServiceLocator locates EJB for each call or just the first time?
Dear PingPing Congratulations. Could you please advise how the travel agents to booking airfare (via Browser or applicaton)? It seemly only says the customer using the web and the travel agent using an application for the FFMS; Thanks

Yes, travel agent use Java swing and customer use web browser, when you design your business logic in EJB tier, different client will share business logic, just add business delegate Patten.

Dose it mean the travel agent use Java swing application to "booking airfare" and FFMS? Is that the travel agent can only use application for all the 7 use cases, so travel agent can not use WEB anyway?
From the management's interview it seems that Travel Agents will use Java (Swing) Application. I am wondering how would we disply html returned by Frequent Flyer system in Java Client. Since we don't want to rewrite the system again, we will use same perl system.
