Congrats Mark ...
I failed ... only 61%
But I am not sad, it was only 2 days preparation and took it really its first day. I believe I can make it better .. Have pre-ordered Kathy book, hope to receive it and crack the exam soon

Hi Ranchers ...
How detail the class diagram you draw for the assignment part II ? only in concept level or specification level ?
Do you put some "basics" operations and attribute in the class (without going to much in implementation detail) ? since I read at Cade's book, he doesn't put any operation and additional attributes at all ..
Thank you for the help

Hi,
I passed this test long time ago with 84% only with Whizlab's trial version test. It's quite helpfull but it's not really necessary.
Download the trial and read its full version tips.
For practice, I took only test from IBM site and Whiz trial version... try to score high and really understand the questions but not because you remember the answers.
Good luck..
Hi,
I feel confuse to start part II, I would like to finish it within 2 months, I have readed Martin Fowler's UML Distilled, trying to absorb Case Study in Mark Cade & EJB Pattern.. and in the mean time I'm also reading Craig Larman's about Applying UML and Patterns, but this book is quite complicated.. I feel it's a good resource but maybe wasting to much time ?
I don't know if this strategy is worth .. anybody who already passed part II/III maybe can give me some hints ....
Thank you for the help ...

I also waited for this book long time ago, but since it was delayed (now for around 3 months),
so I decided to go without it.
I passed the test last month with 85% using Mark Cade's book, EJB Book from EdRoman and of course Java Ranch
Now I am preparing part II, many people said Mark Cade's Case Study is not good enough for part II... so I hope this book will be good enough but don't know still if it's really worth to spend money for only some pages..
Anyway we will see the reaction of people about this book ...

Ther are gona release this book next week right?


I have no idea when will they release this book, in their website, they said they will release it on 28th March (it means next 2 weeks).
But in Amazon it's stated that it will be released on 19th March.
Anyway I am waiting for this book review if it's worth for Part II ..
Congrats
What books did you use to prepare part II ?

How about if Whizlab put some ads within Java Ranch ? Sure it will really help JavaRanch.
In my opinion following trend in Architecture sometimes not really bad as long as they are
good and positive to deliver better functional
and service level requirements.
Maybe I am wrong to use "trend" as a word to describe here, but I see some positive points, even I don't really agree .. that's way I bring to this forum to see others opinion
In this approach, it doesn't tell you not to use EJB, but to minimize it. For example it doesn't recommend you to use one facade which consist of many EJBs. Even Stateless EJB is the lightest, but there are still extra cost. But also this approach is not so modular which may give some problems.

Thank you for the clear and good description reply.
We are getting closer to the real problem that I addressed.
As you said :


facade can exist of several session beans, each session bean is a facade to it's business objects. So there is no big/fat facade.


This can be right, but I see in my experience that there is a trend to avoid using so many EJB / session beans or I would like to say a trend to avoid using so many (expensive) components.
This approach then put all business objects together under one big facade. Big here means these facades handles many business objects as possible, and simply delegates the request, and these business object should not be Session beans and should be just simply Java class... The reason is because the big facade handles all your need includes transaction, pooling, security and etc.
It seems to be right approach but addressed some problems, and I like your reply about to build a prototype to evaluate the performance/scalability requirements. But sometimes we cannot perform this prototype due for some reasons (like doing SCEA exam part II).
