Dear Members,

I was doing yesterday a Whizlabs Diagnostic test, and had poor score 48 %
And realized that I have really to restudy as well Legacy Connectivity and Common Architecture where I missed half or more of the questions... The only document that I had use to study Legacy connectivity is the IBM Java certification success ( and now I think it�s not enough), and while doing the mock test, had question regarding replication (active and Passive) and really at IBM document there is no details for active replicate and Passive. Can some one please guide me on this, any other notes from ranchers or tutorials written for this and legacy System in general ? the same goes for Common Architecture, please where is the good link to read more on this part ? I really need your help, my exam is coming soon, have just this week to complete my review...

Thank you so much for your time, and consideration

My Best Regards,

Rania

Well, a good start is the JCA web site: http://java.sun.com/j2ee/connector/

JCA is a good solution to legacy connectivity.

BTW, please visit my community: "breakingit.ning.com", you will find a lot of Enterprise Architecture things there.

Hi Rania,

Please download documents from the yahoo scea group links.
You have to join this group to download the documents, there you will find documents for all the topics.

And see this link also http://stephane.weber1.free.fr/SCEA/SCEA_Links.html
And find there is one PDF which is made by Pete Morgan as the study note there also you woll find good notes of Comm.Arch also.

Hope this will help.

Hi Manish and Thank you so much for your prompt answer

Actually I did join the Yahoo group, but find my self bit lost on that forum, so went bank to my document and book that I have... but can you please guide me which section on Yahoo group I�ll find the document. AS I mentioned Above, my weaknesses are on Legacy Connectivity /System and common Architecture as didn�t read much on those topic, so please if you can give me the direct link for those Topic at Yahoo SCEA group I�ll grateful... My Exam is Next week, I hope I could Make ..otherwise I'll postpone it (and I don't want this ) ...
Also I�m doing some Whizlabs test, and find many questiona confusing even some was sure that the answer given was wrong.... Did you use Whizlabs in your preparation, did you experience the same?

Thank you so much for your quick response. I�m running out the time ...
My Best Regards

Use this link:
http://tech.groups.yahoo.com/group/scea_prep/links
It will ask for your yahoo's username / pass.

See the left Panel there you will find two important links:
1. link
2. files.

See both you will find material.

but Rania, on legacy connectivity there are only basic ways which you can read from the Notes of many people available in Java Ranch only.

Then for the use of JavaIDL and RMI/IIOP for Corba legacy and Java connectivity.
Remember thumb rule:
1. If Java Client needs to communicate with CORBA server then answer is JavaIDL.
2. If CORBA client needs to communicate with Java / RMI Server then answer is RMI/IIOP.

This will solve all questions regarding Corba-Java connectivity.

Regards,
Manish

Hi Manish and Thank you SO much for the prompt response, I was a bit confused on when to use Java-IDL and RMI-IIOP .. the question Given on Whizlabs test sometimes how they descibe the architecture of the app and then when they ask you which best protocol needed, I most of the time, failed to answer and chose the right protocol
I really need to day to make small summary about each protocol and when they are best for given senario...

For the Yahoo link, Thanks, indeed they are much document, but the truth I'm afraid to mix more my self ... as my test is begening on next week, I may just need make last review from Summary of Mark Cade, and Pete Morgan Note are also Good ( found it yesterday when you gave me the link )

PLease Manish what do you advice me as review for the few days left before the exam ?

I did yesterday 2 Whizlabs test, one got 58 % the other one 65 % , the first one had 5 questions related to Message Driven Bean.... Also some question for Design Pattern that include Business Delegate and Front Controller ...Mark Gade didn't Cover them, are these Pattern Included in the Exam ?

Thank you so much In advance if you can answer my question and have some advise before the big day ...

My Best Regards,

Rania

You are getting good score from whizlabs, if you read the ex. of other people.
I haven't used whizlabs

You will get not a single question of MDB's or J2EE Design Patterns so dont bother about that, so if remove those questions from the test your score would be more then 80% and that is a very good score in whizlabs.
You will find the main exam little easier then these mock one.

For reviewing, I have just studied EJB for one whole day and then on the day before exam I have just revise all the topics from the notes of Pete and other .
On the last day I studied in the morning for 2 hours and then around 15-20 mins before exam.
But I suggest you just study for around 1-2 hrs on the exam day in the morning and leave studying anything before exam for around 1-2 hours.
And have a nice sleep before the exam morning.
Be fresh before exam because it requires your mind to work there.
Use your common sense while answering questions.

Rest of the things will come into place.
Just brush up few things from EJB like transaction, what happen to the Transaction when this exception throws.
There is table given in the EJB specs in the Exception handling chapter.

BEST OF LUCK for the EXAM. You will be successful

Regards,
Manish.

Thank you and Thank you so Much Manish for your nice reply with all good advices
You know, last time when you gave me the two main roll to remember regarding legacy Connectivity
1. If Java Client needs to communicate with CORBA server then answer is JavaIDL.
2. If CORBA client needs to communicate with Java/ RMI Server then answer is RMI/IIOP.
I put write down your role in small paper and each time read them every where to not forgot them
During this weekend, I did the mock test left from Whizlabs, and review some legacy System and Protocols �To day I have to review EJB and EJB Container and Design Pattern, I noticed in doing mock test that I mix on selecting the right pattern described, specially Template Method when it�s given with strategy Pattern ... I hope it�s whizlabs scenario that were long and tricky ...
After EJB review, tomorrow I have to scan very quickly all chapters from Cade�s book and as you said Pet Morgan�s document
I�ll try to weak up early on day exam to make a quick global review and than that�s it time for the exam at 8:30 Hope I�ll be fine ...
Please I have question for you if you don�t mind .. you said is good to review the EJB in the Exception handling chapter, is it from ED Roman book ?
Thank you so much again for you help
My Best Regards,

Rania
