hi, dear ranchers

After waiting for more than 4 weeks(nearly 5 weeks), I got the examination result of Part-II. I passed it. I am very happy about this. Here is the grading information:

==========================================================================
Test: Sun Certified Enterprise Architect for Java 2 Platform Enterprise Edition Technology Part II (310-061)
.
.
Grade: P
Score: 90
Comment: This report shows the total points that could have been awarded in each section and the actual amount of points you were awarded. This information is provided in order to give you feedback on your relative strengths on a section basis. The maximum number of points you could have received is 100, minimum to pass is 70.
Class Diagram (44 maximum) .......................... 36
Component Diagram (44 maximum) ...................... 42
Sequence/Colloboration Diagrams (12 maximum) ........ 12

==========================================================================

It took me nearly one month to finish the partII and III. The assignment was filled with so many questions, and I was also not very sure about the assumptions I made. But judging by the result, it was not necessary to worry about this.

Thank for all ranchers here, and wish all good luck.

Okey, I passed the SCEA examination finally. It is time to give a summary now.

Since 2000, I have been struggling for Java and Sun's certifications. I took part in SCJP exam in 2001, SCJD in 2003, and SCEA in 2005. It was a long procedure to pass SCEA. I took the Part-I exam in Aug 2005 and passed it with 83%, but used one year to prepare and finish PartII&III. The reason is I was too busy in my work. I just felt tired and didn't want to do anything after back home. I stopped my work one month to do the PartII assignment. It paid out too much, but it was worth a lot.

To prepare the Part-II, I created a folder named as 'SCEA/PartII' in my laptop. I put the download materials in it, also including my reading notes and design. Now there are more than 40M files in it. My bibliography includes:

1.Core J2EE� Patterns: Best Practices and Design Strategies, Second Edition(Deepak Alur, John Crupi, Dan Malks)
2.Matering Enterprise JavaBeans<Third Edition> (Ed Roman, Rima Patel Sriganesh, Gerald Brose)
3.Sun Certified Enterprise Architect for J2EE Technology Study Guid(Mark Cade,Simon Roberts)
4.Sun Certified Enterprise Architect for J2EE Study Guide (Exam 310-051)(Paul Allen and Joseph Bambara)
5.Design Patterns-Elements of Reusable Object-Oriented Software(GOF)
6.Java Design Patterns: A Tutorial (James W. Cooper)

I think Book 1&2 are valuable referenced materials for PartII, especially Book 1. I very very agreed to the comments from Martin Fowler 'Don't build an enterprise bean without it'. it would solve the design problems and bring non-functional benefits to your architecture by applying some core patterns in your design. Book 3,4,5,6 are mainly used in PartI. Of course, they are all the fundamentals for PartII. I referred to book 3 and 4 in PartII design.

After I downloaded the assignment from certmanager, I spent considerable time to read the materials and requirements. I am not an English speaker. I saw someone posted the suggestions 'read carefully your assignment until your eyes pop up' in ranch, and I made a foolish way to translate them into my native language. The assignment is tricky I think (just like Sun's
programmer certified exam), it is very very not similar to do a project in real life. My feeling just like on-the-fly, not walking on the ground. To make clear what on earth you need to do for your assignment, my only-one suggestion is to 'read and search the posting in javaranch day and night until your eyes pop up'. Using more searching function, less questions. I collected some valuable posting, which I classified them as 'somebody passed said':

As an architect, you should have the ability to transfer the business problem into abstract business model. We call such a procedure as OOA&D. The bibliography listed above does not include this part. I learned such a methodology through the ICONIX process by Doug Rosenberg and Kendall Scott. You could google it and find a word document named as 'Driving Design with Use Cases'.

Before begin your design, it is better to learn the design example in Cade's book. My way was to design it by myself firstly, and then compared with Cade's answers. Another suggestion is to look through the PetStore example in J2EE Blueprints, read through the codes, and the description article from Sun:

I began my design with the Class diagram, and then the Component, lastly the Sequence. I think someone would be interested in such a question 'how many classes or components in your diagram, and how many diagrams in your design', yes, I was also a fan overjoyed in this. I saw different posting on this question, and found no one standard answer for it. Just like many arguments in ranchers, you should have your own judgments for them. Make your choices in your best reasons, and keep your design clear and simple, and then upload it. The rest thing is 'Sit tight, Sun will highlight your life.'
