has anyone experience with the EPracize mock exam? If so, what do you think about it?

Hi,
I tried EPractize's Trial SCEA simulator. There GUI looks OK and handy to me.
But I have several questions where I doubt the correct answer from EPractize, like this one:
Is it possible to specify the number of EJB instances to pool during deployment time?
Select one.
A: True B: False
EPractize anser is A. But I opt for B.
The reason why is, that yes application server like JBoss etc. let one set the pool size but from the view of the EJB specification there is no word about it. Hence from the perspective of EJB I would say B.
Or what is the Deployment Descriptor element for the pool size setting
Do you see something like "Will this code compile" kind of questions? Are all questions scenario based? Have you used Whizlabs simulator? how do you compare both of them? Did you have a look at the free word document containing 282 free questions? How do you compare these two? I would highly appreciate your feedback on this.
Note that To achieve scalability, the container selectively evicts some bean instances from the cache, usually when cache overflows. These evicted bean instances return to the free bean pool. The size and behavior of each cache can be controlled using the cache-related properties in the EJB container or the sun-ejb-jar.xml file. (ref from http://docs.sun.com/source/819-0079/dgejb.html#wp34104)
Refer Sun's tutorials.
Hence A is the correct answer for the following question.
Is it possible to specify the number of EJB instances to pool during deployment time?
thanks for your response. Well, I still doubt that A is the right answer :roll:
You point to Sun's Application Server XML sun-ejb-jar.xml. And not only Sun's application server but all other application servers do have their own specific configurations XML similar to sun-ejb-jar.xml, so does JBoss Application Server also have his own XML.
Nevertheless, from the perspective of the EJB spec there is no guarantee that those application servers let you set the bean pool size through such XML file.
The point is, that you want to be portable to any application server. You do not want stick to one specific application server. The only XML file you can rely on is EJB's deployment descriptor ejb-jar.xml which says nothing about a bean pool size.
What does the rest of you think?

Please read the Pooling and Caching and Pooling Parameters section from the following link.
The creation and destruction of beans is expensive. To reduce this cost, The EJB Container/Server creates pool of beans that depending upon vendor specific configuration, you need to give a proper value for this pool size to increase performance.
For example weblogic's weblogic-ejb-jar.xml has an element <pool> and JBoss server's jboss.xml has an element <instance-pool>. see your application server vendor documentation for configuring your EJB server pool size.
I know what you are saying, but you said that already . It doesn't change my mind :roll:

I tend to agree with Darya. Although it makes sense that app server vendors provide the option of setting the pool size, there is no mention of that in the spec. So there is nothing preventing me (if I had the skill to do so) or some one else to implement just the spec, and say have static pool size of 10 with no option to change it.
I have seen these types of questions before, and I'm almost certain I even saw one on the exam. I have always thought that as long as it's vendor specific you shouldn't rely on it. (At least that's the case when studying for SCBCD). However as SCEA isn't tied to one specification prehaps one can advocate for answers tied to vendor specific implementations. Although there is no guaranty that the answer will be correct for all app servers (just all usable app servers )
This question is not a sample of what the exam would ask since it is asking a deployment specific question that is part of the application server and not part of the J2EE specification. Focus your attention on the J2EE spec and you will be fine.

Hi Mark,
thanks for clarifying .
After having clarified this uncertain question from EPractize I want to say that nevertheless, this new product makes a very good impression on me and that I'll definitely use it for further SCEA I preparation.

Darya, that is the fourth time! People are starting to talk - they are getting very suspicious! Conspiracy theories are being hatched this very moment...
I am using EPracize for SCEA Part II & III preparation. This product really impressed me with its project and architecture labs. It presents you with six mock assignments that are based on exam pattern and provides architecture solution for each assignment given. It also provides six mock exams based on Part 3 essay exam for the assignments given in the project lab. I feel it is a comprehensive kit for part 2&3 preparation. However, I feel a little inconvenient with its user interface as it requires 1024*768 display resolution but I usually use 1280*1024.
Overall, this product makes a very good impression on me. If you are looking for SCEA Part 2 & 3 exam preparation material, I feel it is what you need.

yes.. epractize labs is the best product for scea certification preparation. some of my collegues evaluated almost all the simulators and mock exams in the market and finally epractize labs got highest score. i strongly recommend this tool for scea aspirants.
Has someone ever tried to print the Epractize SCEA 2 Assignment mocks? I really bored because we can't - Is there any way?
Thanks

Hello Aurelio Calegari,
We do not provide print feature as the materials are copyrighted to EPractize Labs. Print will help people to freely distribute the materials without our knowledge. That is why none our products have the print feature.

Use SnagIt to capture the screen and then print it. Of course its tedious but just in case you want it sooo badly.

Hey Jeff,
That's what I wanted to avoid, but I'll have no way out.
I think epractize folks should make available one mock assignment for trial version, so people can reallize how it's uncofortable to work with these assignments.
Be warned - the exam questions are clearly not written by a native English speaker. Example: "[Some Company] is not interested any more to add any infrastructure software apart from web server and database". Or another: "deployment time needs to be improved whenever there occurs changes in the tables". Or another: "During production deployment you noticed that your web server residing at DMZ, serves only static contents and other components are running in the application server". Say, what? Given that absolute clarity in an exam is essential, this is frustrating.

..plus you have to do a fiddly registration which involves emailing their support team and waiting for them to send you an activation key. Perhaps their web developers should take their own exam..
Hello,
I am trying to pass the SCEA 5 first part, I have the Whizlabs Simulator, do you think is better EPractize Labs or any other tha you can suggest me?

I used whizlabs to pass part1 .. It is good at ensuring you are ready to pass the exam.
It in my opinion has 1 major flaw. the answers reference various URL's. unfortunately you cannot click on the url or copy the url to past in your browser.
I have heard some good things about (sorry probably misspelled) ethuware. when I posted my gripe about wizlabs (above peeve), ethuware came back and said that was a feature of thier product.

I can attest to what Si says about ePractize. I found it a pain to deal with them on this, especially if you move to another computer and donate your old one, or change configuration etc. The product wants that key AGAIN. You have to send again for another one and hope the give it to you. I made this mistake with the SCJP mock they have. I will never buy any of their products again, nor do I recommend them to anyone.They were not very friendly either. I was lectured and warned about using another computer/laptop, and accused, even though they have my money.
Nothing but frustration! Enthuware saved the day.
