Hi all,
I just passed 1Z0-895 with a score of 85%

My official title is now: Enterprise Edition 6 Enterprise JavaBeans Developer Certified Expert

Thank You Frits Walraven for your EJB 3.1 Summary and Enthuware for your excellent test preparation software!

I agree with Alexandru; you have barely enough time as most questions have a lot text and code which you have to read very carefully especially if English is not your native language.
I wished I had more time to review some questions I was not sure about but there was no time left....

Other sources I used are the KnowledgeBlackBelt EJB3.1 course (doesn't exist anymore but I have a PDF), and the support at the JavaRanch SCBCD discussion forum

And how long did you prepare for that?



I did not know what to expect from the assignment, so my preparation was minimal.
My greatest resource concerning important decisions were all the discussions here at Javaranch!!
I have spend lot of hours here reading about fat/thin client and so on.

I have a full time job so I had to do everything in my spare time
Still I found the 6 months enough time to complete the project.

My Assignment was URLyBird 1.3.3.

Here are a few design choices I made:

I used the thin client approach and used the ThreadID as identifier for the locking mechanism.
As there was no Cookie in my interface this architecture really made sense.
This made my locking solution very easy and small, I implemented it in the Data Class itself.

For the GUI I used MVC, letting the controller act as a event listener/handler, where all the view components use the controller as the event handler.
This way I have a clean View class (no inner classes) and a nice separation of view and actions.

Hi all,
I just passed OCMJD with a score of 373 that's 93%

A big Thank You for all at Developer Certification (SCJD/OCMJD), all those topics over the years are a great help for anyone who works on this certification.

Thank you Roel!

My URLyBird must be ready in October this year, so I will stay with JDK6.

I guess using JDK7 won't get me extra points, while I may take some risk by developing with it.
Hello Everyone,

I am working on the 'Oracle Certified Master, Java SE 6 Developer' certification.
As the title suggests this certification is about Java SE 6 right?

But the instruction state that the Java 'platform must not have been superseded by a new production version for more than 18 months by the time you make your submission.'

So right now I am confused, should I develop on JDK6 or JDK7?

JDK6u33 was released June 2012 so I guess using this must be OK, but Java6 is an older version.
JDK7u5 was released May 2012, currently the newest Java version.
Because my application (urlybird) was developed on JDK6 it also works on JRE7.

If I would use JDK7 should I use new features which did not exist in JDK6?

Thanks in advance,
Bas
Hi all,

Yesterday I passed the exam with a score of 90%

Thanks to K&B for their excellent book!
Actually I found the exam questions to be easier than those in the book...
