I used a simplified version of WAF and I passed part II with 94%
Kaiser,

Did you change the "Seats" from BDOM with "Seat" ?

Congratulation Remus !
Do you think that is correct to update asynchronously the mileages in FFM ?
Because that Corba object could be implemented in C++ or whatever language. Even if the CORBA object would be implemented in Java you have to create a remote interface.
Could you tell us about Part III ? Was related to part II ? Is there any need for a special preparation ?

Is it possible as 2 entities involved in a CMR relationship to take its data from 2 different databases ? One of them from a database and the other one from another

Josep,

The cache will be kept in the business tier, thus it will be available to
both types of clients.

Look here at what is written in the Pet Store. The Segment, Flight, Equpment classes are somehow similar with Pet Store's catalog classes.

"Catalog entries are modelled as conventional classes. In this application, catalog entries provide an excellent example of when not to use enterprise beans. Catalog entries are simple, tabular data with little or no behavior. They do not need the services enterprise beans provide. For example, because they are read-only, they don�t require concurrent update management or transactions.

Modelling catalog entries as entity beans would create unnecessary overhead.

Modelling them as conventional classes meets all of their requirements in the simplest, most efficient way."

In addition, you can avoid database calls by caching segments, flights, and equipments.

Congratulation Gavin,

How did you solve the problems with crisscrossings in the component diagram ?

For example, a service locator is referenced by many ejb components or business delegates and that is why there are a lot of crisscrossings.

For example, a service locator is referenced by many ejb components or business delegates and that is why there are a lot of crisscrossings. I am going to put a label connected to the ServiceLocator writting in that all
delegates and session beans have a reference to the service locator.
