I just finished my OCMJEA Essay and now I'm waiting for my results (really hoping for the best..). I want to take advantage of the upcoming holidays where work is easy and relaxed (plus my vacation, sadly) to take on the mandatory training. Regardless if I pass/fail on the assignment & essay, I will take the training anyway so I won't wait for my results. I'll probably try and try until I pass. Anyway, I have a few questions about the mandatory training:

Is it OK to purchase the course from the Oracle country site where the cost is much cheaper? For example, there's a significant difference among the training costs for the course "Developing Applications for the Java EE 6 Platform":

$3600 from Oracle US
$1187.35 (Php 53395) from Oracle Philippines
$913.52 (Rs 56570) from Oracle India

1) If I'm going for the Live Virtual Class Training where internet is the only requirement, I'll probably buy the the cheapest one. Is this a valid strategy, and have anyone ever done this before?
2) If my vacation is in India/Philippines, can I take the training there? And will Oracle still honor this training?

It's not that the questions are duplicate per se. It's that some facts fit well in multiple questions. And it also helps you to not over-answer an earlier question by accidentally answering a similar later one.



Thank you! Now I'm planning to answer questions using keywords or simple sentences first then going back to them to add more details.
I noticed a lot of mentions that some of the questions are somewhat duplicate of another question. In this regard, I'm thinking about going through all the questions first and then answer according to topics. Is this possible?
I've done diagramming a lot in design docs but I only mostly use the Lifeline image. And usually, the interface and the name of the implementing class is represented there. I may have used the Entity diagram to represent a data store.

So, I wanted now to make it right, and confirm that I'm using the right representations all my life... UML 2.0, when do you use these other lifeline types...?

Lifelines (mostly rectangles):

Boundary, Control, Entity:


Thanks Jeane for your time. I'm somehow getting correct answers on the mock exams regarding these two.
I tried to analyze this question multiple times and I still didn't get why the answer is proxy... I've always answered Chain of Responsibility here but well, it's wrong. Any thoughts?


You are currently designing your own Desktop Publishing application as you have not found any existing application that does exactly what you want. As part of the design, you are using a Controller to which you send all GUI requests. Not all objects can process the same commands.

For example, you cannot select the spell check tool when an image has the focus. To stop any possible errors, you would like to filter out some of the messages as they are passed from these objects to the Controller object. What pattern could you use?

Choices:
Firewall
Proxy
Adapter
Observer
Chain of Responsibility
Filter



At one read, I'll also answer it with Intercepting Filter but it's not in the choices. So.. in this particular scenario, where is the proxy object?
I'm kind of frustrated already, any ideas?

1) I have initially imported the certificates correctly according to the Apache Tomcat 7 SSL documentation.
2) Then later I found out that one of the certificates is wrong so I asked for the correct one from our security team.
3) I imported the correct one to the keystore using the same keytool import commands.
4) Anticipating that there might be conflicts even though they have different aliases, I deleted the errouneous certificate imported before from the keystore by using "keytool -delete -alias mydomain -keystore keystore.jks"
5) And then boom, I tried my SSL site, and it's not working anymore.. The "https:[..]:8443/" is not displaying anything and this error is showing when you click more: ERR_SSL_VERSION_OR_CIPHER_MISMATCH.
6) Tomcat logs didn't point me anywhere so I'm lost.

Please help?

Ok, so here are some generic statements from the SCEA 5 study guide... which I think apply to both Abstract Factory and Factory.

(1) Eliminates the need to bind application classes to your code. Code deals only with the interface.
- is one of the benefits of Factory but I think it's also applicable to Abstract Factory - True or False?

(2) Provides an abstract class that determines the appropriate concrete class to instantiate to create a set of concrete products that implement a standard interface.
- is Abstract Factory but I think it's also a description for Factory - True or False?

(3) A class wants its subclasses to specify the objects it creates.
- is one of the usages for Factory but I think it's also applicable to Abstract Factory - True or False?

(4) A class cannot anticipate the class of objects it must create.
- is also one of the usages for Factory but I think it's also applicable to Abstract Factory - True or False?

(5) Enables the subclasses to provide an extended version of an object.. because creating an object in a class is more flexible than creating directly in the client.
- is one of the benefits of Factory but I think it's also applicable to Abstract Factory - True or False?

(6) Classes delegate responsibility to one of several helper subclasses and you want to localize the knowledge of which helper subclass is the delegate.
- is one of the usages for Factory but I think it's also applicable to Abstract Factory - True or False?

(7) The system should be independent of how its products are created, composed and represented.
- is one of the usages for Abstract Factory, but I think it's also applicable to Factory - True or False?

What do you guys think?
Due to budget constraints and targets I guess, I have intentions of completing the three parts of OCMJEA for JEE5 this year. And then attend the mandatory training after knocking these 3 parts down later next year. I am already quite experienced and performed architecture tasks at some capacity.

Will I still get certified even if I deviate from the order that Oracle said in the OCMJEA 5 site?

1) My intended order will be : Part 1 Exam -> Part 2 Assignment -> Part 3 Essay -> Mandatory Training (which is really expensive).
2) Or is it strict that I follow this order : Mandatory Training -> Part 1 Exam -> Part 2 Assignment -> Part 3 Essay?

Hoping someone to shed some light and experience on this. Thanks!
I'm planning to take OCMJEA in about a month. Though I really haven't bought any voucher yet. I have been studying the Sun Certified Enterprise Architect for Java EE Study Guide by Mark Cade, Humphrey Sheil.

My question is, given my study material, should I go for the EE6 exam or stay with the EE5? Does they have a lot of difference?

Now I have experienced taking and passing the OCJP6 but studied OCJP5 Study Guide (because the book wasn't out yet and the exam was really new). Will this be the same case as that of OCMJEA JEE5 and OCMJEA JEE6? Is there a significant difference between the two versions for me to know in the JEE6 exam?

Hello guys!

I'm very new with spring roo. I managed to convert my Spring Roo to GWT, and did some CRUD stuffs through the tutorials provided. However, I got stuck with this problem:

1) I have defined fields that I should retrieve from the DB (e.g. Username, Employee Number, etc..)
2) I want to load these fields in the UI of my web app dynamically:

2.1) Retrieve the fields from the DB
2.2) Iterate them
2.3) Show them in my page as "Label of the Field <e.g. Username>" : <Input Textfield>

3) The client user can then enter values and save them somewhere.

These are my entities, generated via Spring roo:



And the transaction entity that's supposed to store my dynamic fields


I am kinda lost on where/what to begin. Hope your expertise can help me. Thank you in advance!

GWT
Can anyone shed some light on me about this? I am quite preparing for SCBCD, but as we all know, Oracle already bought Sun... so am I gonna take the same exam? Are the books for it the same? - I'm reading Head First EJB. Haven't bought the voucher yet.. I'm gonna buy it soon with a guide from this site:

Java Enterprise Edition 5 Business Component Developer Certified Professional Exam

Hope you guys can help me! Thanks!

Same Congratulations to you too!!

I'm really really happy to announce that I got my SCWCD this afternoon with a score of 91%.

It was tough for me... Though I did prepare... dedicating at least an hour every day for the last 2 months... It was also very difficult to keep your concentration when you're doing .NET at work as always Maybe I should try a certification from the other side this time...

You should keep the concepts in your head permanently. I know it's difficult. The exam was not just about memorization, my set of questions were about solutions, analysis of problems, those types...

I read HFSJ three times.. First was the real serious reading, then re-read the chapters again in the order of difficulty (for me). Then lastly, read again for the review of the topics. I also did each chapter's mocks three times. Low scores on the first attempt are acceptable. By my third complete pass of all the chapter mocks, I should be perfecting them all but I didn't ... The final mock exam was too difficult. Of course I wouldn't pass in that particular mock exam.

You would find a lot of good good information from the links here.

Thank you to the following, particularly:

1) HFSJ and its fabulous authors!!
2) Mikalai Zaikin's Study Guide
3) Marcus Green's mock exams, and I did pretty well in there... It was helpful! Thank you Marcus Green for giving me confidence
4) Marc Peabody. I got a perfect score on the patterns ;)
5) Ashok Kumar Babu's complete web.xml guide. Bring this with you all the time!
6) Jothi Shankar Kumar. S SCWCD hints
7) It was fun answering Javaranch's mock exam. You should get perfect scores for these too to keep your confidence up.

Whew it's my best score so far. As always, I keep on checking out the Sun Certification Results forum for motivation and inspiration to pass

Thanks to all again, and I hope for everyone's success too!

I'm so happy!!
