hi Alejandro
I have the same concern. Now what I'm going to do is,
1.classdiagram only contains the BDM and other classes which is tech-neutral, and these classes will be deployed to both fat client tier, web tier,
ejb tier.
2.component diagram contains all
JSP,
Servlet,EJB,DAO,POJO. And there will be no class from the classdiagram in component diagram
3,sequence diagram contains objects from component diagram, also no class from classdiagram
IMO this will be a clear architecture, and I think if I put more into this diagram it will involve more implementation detail, which should not be the job doing in the stage of architecture.
Anyway, I don't feel full confident since this is a subjective exam, maybe I will change the assignment later for a more acceptable deliverable to the examinator.
