is there a Sun website to allow others to inquiry SCEA certificate like www.suncert.com/inquiryscea.do?studentid=xxxxxx ? the response is one's information about the SCEA in html or xml.

thanks
tony
jboss complys JEE including web and ebj containers but tomcat only has web jsp/servlet container. why someone wants tomcat integrated to jboss? i think jboss does more tomcat. why you want both engines running together for you? thanks. tony

First of all, You don't need to know how it is done, this is developers' responsibility.

[Comment], I don't agree. I think it's the right responsibility of architect for the remote secure access. Using RMI over HTTPS tunnel for public network (Internet) access is not a good practice. That's the reason HTTP as a black horse in 1995 led ahead than COBRA and DCOM.

Second, read your assignment carefully. The CUSTOMER need to communicate with you application using SSL. It is not said anything about the travel agent.
[Comment], Agree, be careful to read it. Agents are assumed to keep using the existing private network which was used for 3270 terminal access.

I hate magicdraw but I have to use it. So I used some repeatabl lables like "return" and "return." in sequence. Any way, it's for human reading at this time. Just a bad tip for help you a little. This is not your fault
Q: Any recommendations?
A: focus on high-level not details. Using packages to group the classes and componenets. I refered a lot of PetStore design sample from its web tier. But I don't like their EJB tier which makes the design complicated.

Q: Could You Pls send me links of Free Mock Test for SCEA-I?
A: 1) read Pete Morgan paper as the start point. See http://www.sarahandpete.com/work/SCEAexamnotes.pdf
2) Use Whizlab. It covers most of exam I. I got 87% since I found there 6 questions in the exam I can't answer becuase of Whizlab doesn't cover it.
MagicDraw v10. I don't think it's good tool.
Q: how could your architecture satisfy the requirement on performance, let's say, response time in several seconds.
A: not addressed in my document.

Q: Did you use Aggregation /composition is your class diagram or simply association?
A: Try to use aggregation/composition if you are sure. If not sure, I simply use association.

Q: Did you show EJB home interfaces in sequence diagramms ?
A: No. Treat a EJB as one object.
Today my score is available online after 4 weeks of process. Here is

I believed I got a lot of tips from the forum. Thanks all of you for the help.

I have one class diagram with classes and packages, one component diagram with packages and five sequence diagrams including a login process flow.

I started with the class diagram design and focused on business domain model rather than technology. The classes in the diagram just list the basic data objects which can support the flight booking use at least. Don't spent time on the detail level because the detail class design is the job of the designer not the architect. The architect just defines the framework or basic high level structure. I only have five packages with two or three classes each package to show the overview of class structure .

The component diagram also includes five packages with each consists of two or more components. The communication protocols display among the packages.

I spend a lot of time on sequence diagrams. I think this is not architec work but as required in the assignment I have to be a designer for this. Using UML2.0 can save you lot of time since it support the reference.

The document I have 6 pages for the text description for above three of diagrms plus the sevice-level and design patterns used in design.

You can spend a lot of time on it but keep it in mind that this is the architecture framework design which will tell the others with how the flight booking system works. It's a blueprint for the developers or engineers use. Keep the diagrams as SIMPLE as possible. The exam is viewed by the expertises who have viewed this kind of design for a thousand of times.

After the completion of the assignment, I learned a lot about J2EE design patterns but I don't have much chance to code with it.
Regarding the experience, I would say that a good architect not only deliver the design document but also has ability to drive it for implementation. He/she should know how to deal with the compete developers and how to get the authority to force the development in the architectural direction. The computer system architecture is similar to the construction industry architecture, but is too younger which needs more standard procedures like the engineers can read the architecture blueprint and bulid the house. UML is a visual language but not accurate enought to descript a system. One picture worths a thousand of words. But description with a thousand of words are more accurate than a picture. My point is that an architect needs to execise the communication skills. That is the experience.
There are several roles of architect: enterprise architect, domain architect, solution (or application) architect in USA. The first two architects focus on IT governence and strategy, and the solution architect focus on project level component design. If the component is designed with J2EE solution, J2EE architect is the best role. I would say that most of mid-range companies prefer J2EE architects (or .NET architect). The enterprise companies started to outsoruce the projects in USA.
