Hello,
Anyone has any experience for Python Certification provided by Python institute? https://pythoninstitute.org/certification/pcap-certification-associate/
How good are those - PCEP and PCAP? Are those certifications valuable?

...........
Thank you

I am happy to share that I have cleared  OCMJEA step I exam - 1z0-807. I prepared for 3 months - mainly after office, during weekends and whenever I got spare time in the middle of my office work.  Though my score is just the passing score but I am happy that I can focus on the next step. There was technical difficulties in the computer during the test at Pearson Vue test center. After I started the test, the computer display was disappearing for 2-3 seconds and again coming back. And this was happening almost in every 2 min. I reported this to the invigilator who called Oracle Support team to fix the issue. Then invigilator stopped my exam and asked me to wait in the reception. She worked with technical team and gave me another computer to continue the exam. The exam again started from where I left. The issue still persisted. It was very much irritating and hard to give the test. Every time when I was putting concentration in reading the question, the screen display was disappearing suddenly breaking my concentration. I reported that to the invigilator again. She asked me whether I want to reschedule my exam or I have to continue like this. I thought that it's again painful to wait and read for another week and come back to the test center. So I decided to continue the test with patience and passed with 71%...finger crossed..... I could have been correct few more questing making little bit better score.

Here is my experience  during preparation -
The exam does not check for in-depth knowledge of each JEE technology, rather it wants you to test what is what and what, when it is used, where it is used, where it should be best fitted, what is not to use, where not to use, what are the advantages/disadvantages of different JEE technologies, advantage of one technology over another technology,  different tiers of N-tier architecture, their advantages and disadvantages, advantages and disadvantages of 1/2/3/N tier architectures, different layers, different laws like leaky abstraction, open closed principle, interfaces segregation principle, common reuse principle, interface, inheritance, encapsulation, composition, identifying GOF design pattern based on given scenario, identifying JEE design pattern based on scenario, find useful integration technology based on given scenario, scenario based anti patterns.
All the questions are scenario based. There is almost no straight forward questions. So it is required to do lot of scenario based question before appearing for the test.
I have bought myExam cloud simulator. This is full waste of money. I wasted my money and time by buying and practicing this. Here 90% questions are one liner straight forward. The questions are not updated and connection is slow. Answer explanation is not good.
I bought whizlab too. This one is better and updated. Questions qualities are better than myExam cloud but yet not up to the expectations. Far more easier than actual test. Final exam of this simulator is good but still much easier than real test.

Here is the link of the questions which are almost of same standard(not updated to JEE6).

I have studied following books during my preparation:
 1. OCM Java EE 6 Enterprise Architect Exam Guide by Paul Allen & Joseph Bambara. A must read book. Need to read thoroughly. Though practice questions are not good.
 2. Sun Certified Enterprise Architect for Java EE Study Guide by Mark Cade & Humphrey Sheil( Good book giving a good overview)
 3. Core J2EE Patterns: Best Practices and Design Strategies by John Crupi, Deepak Alur, Dan Malks. A must read book
 4. EJB 3 in Action - in depth reading is not required. But need to read hand get sufficient knowledge of different EJBs and JPA
 5. GoF design Pattern - any good tutorial site. Paul Allen & Joseph Bambara's book is also good on this.
 6. Java Web Services: Up and Running - by Martin Kalin. In depth reading is not required.
 7. JEE 6 documentaion whenever requred to understand something - https://docs.oracle.com/javaee/6/tutorial/doc/



Hi Pavan,
I am preparing for 1z0-807. I have read a list of book along with Allen and Bambara.  You can discuss your questions/topics here with me.
Hello Adriano,
Thank you for the reply.
I am currently practicing with Whizlab simulator. Is real exam similar to Whizlab? Do you have any suggestion on taking real exam after how much average score of Whizlab simulator? Could you please share your average score for Whizlab test or score for all the mock test? This will give me a clear picture of my readiness and confidence to take exam. I am scoring from 78% to 85% in the mock exam in the first attempt.

Thanks.
Hi Adriano,
Congratulations on your achievement. I am also preparing for OCMJEA and have targeted to appear for 1z0-807 in July.  Thank you for sharing your experience and preparation path.

Did you use any mock question(simulator other than whizlab?

Did you read any book for Security part?
Thanks.
Hello Barry,
Have you already cleared 1z0-807. I have just started with Paul Allen's book. Requesting you to share your preparation and experience which will help future aspirants like me.

Thanks.
Swapan.
I tried earlier this option but did not work. every time when I run javac -version, output with javac version was getting displayed. But when I tried java -version, it was throwing jre not found error.

Now again I verified path variable details. I removed an extra existing java path - C:\ProgramData\Oracle\Java\javapath;
After that java -version returned java version successfully.
Thank you so much for all your help.

Congratulations Praveen. I am planning also for this certification. Do you mind to share your preparation story? It will help future aspirant like us.
Also do you have any information when Oracle is going to release new version of OCMJEA
Thanks Carey.
I have installed jdk 12. Now while I am installing eclipse 2019-03, it is throwing error that java runtime environment not found. So if JRE is not present in my computer(as I removed Java 1.8 from my computer) and jdk 12 does not provide jre, how can eclipse be installed?

Where can I find jre 12? Is it still free?

A method or operation can have return type. So "return type of Stream" is basically incorrect statement. Correct is - what is the return type of Stream operations. Stream has intermediate operations and terminal operations. All intermediate operations returns a new Stream.  Different terminal operations have different return types. You need to understand and remember what each Stream terminal operation is doing to know about Stream operation return type.

Thanks Carey.
Even I noticed that there is no jre for Java 11. So what is the latest version of jre? Will all the features of Java 12 run in lower version of jre?

I have installed jdk 12 but don't see any jre 12 present in my computer. Does not Java 12 include jre 12? Or is not there any jre 12?

Hello Edmund,
I don't have any answer for your first question. I would suggest to call oracle support center and ask your first question.
Regarding 2nd question: You need to clear two exams for this certification - 1Z0-815 and 1Z0-816. So when you are prepared for 1Z0-815, you can buy a Oracle Certification Proctored Exam Voucher from education.oracle.com. Link is https://education.oracle.com/certification-exam-vouchers. The voucher is valid for 6 months. After buying voucher, you need to schedule examination from Pearson Vue - https://home.pearsonvue.com/test-taker.aspx. Go to this link -> search for 1z0-815 -> login (create user id if you don't have) -> schedule exam(use your voucher here).
