Greetings,

Im seeking for MySQL certifications starting from the Associate one, i discovered that there is a "CMA" from MySQL website, and "SCMA" from Sun website (this is also for the rest of MySQL certifications).

Can anyone tell me if there are differences between them? and if yes? which one is recommended?

Best Regards,

And thank you for sorting out my quotes, Ernest.

Well, I noticed that this message "java sucks" is stored under FOLDER "aprilfools"!!!

Do you think Javaranch site is hackable to the extend that someone can create such a folder and put an image file that contains this message???!!!.....I dont think so

Today i have cleared the exam, it was very easy and usefull for me, specially the sections that was related to explain a good introduction about many technologies, such as J2EE and J2ME technologies.

Kindly notice that this certification is important even if you have already got the SCJP certification, because it covers many different areas which allows you to seek for advanced certifications as it is considered a very good starting point.

Good luck for everyone.

Best Regards.

Hi Larry,

No its not included in the SCJP exam, and you can see the differences between SCJP 5 and SCJP 6 in this url:

I dont think it's necessary for the exam, but it's good to know about it.

About the return type, what you said is true ONLY if we were talking about Java 5 or above, otherwise its not allowed.

The key point here is that when you declare a method inside an interface, it should be ALWAYS "public abstract" and when you declare a variable inside an interface, it should be ALWAYS "public static final", that means when you override any method from an interface, your overriding method should be public, otherwise it will not work because it will be more restrictive.

Which of the following pieces of code, placed on line xxx, would allow this class to successfully compile?

a) private String doIt() {return null;}
b) Object doIt(int i) {return null;}
c) Object doIt() {return null;}
d) public String doIt() {return null;}

Book's answer is "(c) and (d)", but actually (c) is not correct because its more restrictive.

Dear ranchers,

Today I noticed in the Certification book an error in Question 13 Page 333, it says that options (c) and (d) are correct, while option (c) is not correct because its more restrictive "like option (a)".

I have no idea if there was previous disscussion regarding this issue, but anyhow i noticed it while reading the book.

Any comments about this issue?

Thank you.

Jeanne,

Thanks for the reply, i read many articles and manuals, but still didnt find this log, because there are many logs generated by Oracle Application Server for different purposes.

Thanks again and have a nice weekend.

Dear Jeanne,

Thank you very much for your response, you are right, it should be written in a log file, but the problem is that where is that log file? im new in Oracle Application Server and im trying to improve my skills.

Your response is highly appreciated.

Dear ranchers,

I recently used Oracle Application Server and deployed my WAR file in it.

My question is: where can i find the output of the exception printStackTrace() in Oracle Application Server?
