Yes, it looks strange. And I feel nobody does it.

It is used non-portable implementation of EJB. EJB component is coupled
to Oracle VPD technology.
The idea is to verify datasource configuration on deployment,
and if database version is wrong then deny deployment.
I know that binging to datasource can be changed after deployment,
but VPD requires redeployment in this case.

Hi!
Is it possible to deny deployment of ear by itself?

Thanks a lot.

Hi,

For example,
In the design model there are there classes:
Customer 1 - * Sale 1 - * SaleLineItem.

If Sale is implemented as EJB Entity bean,
is it right that in the component diagram SaleBean component provides Sale interface, or in this case Sale in the class diagram must be interface?

Thanks a lot.

Hi,

I am confused, how detailed Sequence Diagrams should be.

For example, we have Sale-SaleLineItem-Product model.

- Should SD show only handling of system events? E.g. interaction of SaleUseCaseFrontController, SaleUseCaseBusinessDelegator, ServiceLocator, SaleUseCaseApplicationController, DAO, �
Like SD for Application Controller in "Core J2EE Patterns" book.

- Or should SD show more details? E.g. interaction of about components + interaction of domain classes: how Sale, SaleLineItem, Product are created. How they are linked.
Like in the "Applying UML and Patterns" Chapter 17.

Thanks a lot.

Hi Ilja,

Thank you for clarification.

Hi,
I have some questions about Association Class.
I understand that there can be only an instance of the association class for any given pair of objects

- Can be Association Class added for one-to-one association? Is it common?

For example, there is association Flight-Airplane 1:1, and association class Assign. Class Assign has two attributes: data, time.

- Is it possible by instance of association class Assign find corresponding pair of object Flight and Airplane?

- Although the multiplicity of association is 1:1, is it correct that in different time Airplane can be assigned to different flights, or multiplicity must be *:1 in this case?


Thanks a lot.
