questions on entity bulk operations
Wed, 7 May 2008 12:42:53 MDT
Hi,
 
I have a hard time here to understand some points from the persistence spec:
 
Question #1 - The persistence context is not synchronized with the result of the bulk update or delete.
 
 quote:

 
The persistence context is not synchronized with the result of the bulk update or delete.
 
Caution should be used when executing bulk update or delete operations because they may result in inconsistencies between the database and the entities in the active persistence context. In general, bulk update and delete operations should only be performed within a separate transaction or at the beginning of a transaction (before entities have been accessed whose state might be affect...


will the Query object always take preference over EntityManager on setting flushmode?
Wed, 7 May 2008 11:28:53 MDT
Hi,
 
I have a question regarding the flush mode setting on either the EntityManager or the Query object.
 
since the setFlushMode method is available in both EntityManager and Query interface, then which one takes the preference?
 
For example, If the EntityManager has been configured with setFlushMode(FlushModeType.AUTO) and the Query object has been called with setFlushMode(FlushModeType.COMMIT), then will the preference goes to the Query object? (COMMIT in this case???)
 

thanks

Strange annotation - @EmbeddableSuperClass

Hello dear ranchers!
 I have read O'Reilly book, and then started read specs. I've found @EmbeddableSuperClass annotation in 2.1.9.3 paragraph.
 Behaviour of this annotation is exactly like @MappedSuperClass, and I don't see @EmbeddableSuperClass in Java EE packages.
 Could anyone explain this moment? Thanks.

Confused about mappedName
Tue, 6 May 2008 05:30:49 MDT
Hi Ranchers,
Ive been reading the EJB in action , and I am very confused about the use of mappedName attribute in different annotations . they say it could be used in @EJB , @Resource , @Stateful , @Stateless , @MessageDriven.
As I understand it specifies the gloabl JNDI name of the bean/resource.For example if say @Stateful( mappedName ="GlobalName") public class ...
and I reference the bean in another class like @EJB(name="somerefname" mappedName="GlobalName") then at deployment time there is mapping done between ENC ref java:comp/env/somerefname and global JNDI name "GlobalName" in a server specific xml file .In case of @MessageDriven it is mentioned that the mappedName specifis the JNDI name of the destination.I dont und...

crazy on the enthuWare simulator ordering...
Mon, 5 May 2008 08:34:46 MDT
Hi Mr. Paul Anil,
 
I have to call your help here since I am crazy on order the EnthuWare EJB 5 simulator now.
 
I ordered first time last Friday using my american express credit card and I got the customer service reply and it was unprocessed and cancelled without telling me any reason.
 
Then this morning I used my another citi master card did another ordering, I watched my processing status changed from in process to unprocessed again within 2 minutes.
 
I am wondering what's wrong with either of my orders??? or could be the RegSoft payment processing system has some problem, but at least they should let me know what is the issue? 
 
I am crazy now.... How can I get the simulator now????...

a question regarding chap 9 ejb3 in action
Sat, 3 May 2008 00:54:30 MDT
i am bit puzzled about the chapter 9 listing 9.1
 
code:
public Item undoItemChanges(Item item) {
entityManager.refresh(entityManager.merge(item));
return item;
}
public void deleteItem(Item item) {
entityManager.remove(entityManager.merge(item));
} 

 
shouldnt the above code be like this:
code:
public Item undoItemChanges(Item item) {
entityManager.refresh(item);
return item;
}
public void deleteItem(Item item) {
entityManager.remove(item);
}

 
in the code mentioned in the book , why is entityManager.merge(item) used as a parameter to methods refresh and remove?...


Passed SCBCD 5.0 with 86%
Fri, 2 May 2008 10:56:28 MDT
Hi All,
 
I've just passed the exam this morning.
I answered 8 questions wrong.
 
Almost 50% of the questions were about JPA.
Just 1 Drag&Drop question (I'm lucky because this type of question can't be reviewed!)
4 questions about Security (I failed 3: for me it was a difficult part of the exam).
 
I studied 1 year (only during free-time, at work).
I used:
- O'Reilly EJB3: Very good introduction to EJB3
- EJB3 Specs: my only reference
- Enthuware Mock exam: Very good and close to the real exam
 
Many thanks to all of you: This javaranch forum was my best help !

Passed SCBCD 5.0 exam with 91%
Thu, 1 May 2008 09:50:25 MDT
I`ve passed SCBCD 5.0 exam yesterday with 56/61 correct answers. I strongly recommend these three positions:
1/ EJB 3 in Action
2/ Mikalai Zaikin`s "SCBCD 5.0 Study guide"
3/ Enthuware EJBPlus V5 Simulator 
 
I`ve started to prepeare for the exam exactly two months ago, having no earlier knowledge or experience with EJB 3. The first problem I had to solve was lack of the "Head First EJB 3" book on the market I`ve spent plenty of time searching topics in this forum to find out which is better - o reilly`s "Enterprise Java Beans 3.0 5th" edditions or Manning`s "EJB 3 in Action". Even though many peaple have written, EJB 3 in Action is too introductory book, I don`t regret from today perspective, I`ve decided for th...

Gurus,
 
Can any one please tell me whether I can take the Sun Certification Web Services exam (SCDJWS) before taking the Sun certification Business component developer exam (SCBCD). I am asking this with respect to level of difficulty/complexity and not with respect to the eligibility of taking the test.
 
Is it better to take SCBCD first and then SCDJWS ? 
Do you have any ideas/suggestions?

@EJB annotation from servlet and JBoss

how to understand this regarding multiple message listener method?
Wed, 30 Apr 2008 10:40:22 MDT
Hi friends,
 
I need someone's opinion regarding how to understand this statement from MZ's note:
 

 quote:
 
A bean's message listener interface may define more than one message listener method. If the message listener interface contains more than one method, it is the resource adapter that determines which method is invoked. 

 

To my knowledge, the javax.jms.MessageListener only defined one single method - onMessage() which the bean need to implement, so how to interpret the above quote? I am guessing that could that actually means that the bean can implement different MESSAGE LISTENER INTERFACE for the messaging type that the message-driven bean supports...


Application exceptions and BMT
Tue, 29 Apr 2008 11:18:19 MDT
What will happen in a stateless or MDB with BMT demarcation if we throw an Application Exception after the transaction has been started but not commited ?
According to specs, the app-exception will be re-thrown.
But, according to specs too, these ejbs need to commit or rollback the transaction before the method ends.
 



About SCBCD preparation
Tue, 29 Apr 2008 02:34:18 MDT
Hi, I am a new guy here, and I have passed SCJP with 80% and SCWCD with 88% not far from now. 
 
Recently, I have been preparing for SCBCD, so I gotta couple of questions for you all:
 
a)condering the expiration of the dated SCBCD, is the background of the EJB2.0 necessary for me?
 
b)after scaning your topics, I find I am confused by the term "manning book", so what is that about? 
 
Thank you in advance.


SCBCD
Mon, 28 Apr 2008 01:02:14 MDT
I have been using EJB 2.1 from a long time and wanted to take up a certification on the same. But the exam now has been phased out, I suppose, as I could not get a link for the same in Sun's site.
 
If SCBCD 5.0 is the only option now, why isnt there a HFEJB book for the same? Or is it available? 
 
HFEJB for EJB 2.x, makes learning fun and I would like to know if there is something from Bert & Kathy CO. for SCBCD 5.0


be careful while buying the books in Hyderabad

Hi,
I went to one of the famous book stores of Ameerpet,Hyderbad called Rajalakshmi book shop to buy the required books of EJB(Manning 3.0,Headfirst).
I was very much surprised when i saw the books. The guys over there are selling the books by making a xerox of original book. I have noticed it because the paper quality of the books is very cheap and any one can be easily fooled as there are only minor difference in the original copy and the xerox copy. These days we are very much aware that it is possible to a take a xerox of any thing in such a way that it matches the original cent percent. 
I just thought of sharing my experience. Please pay attention to these kind of issues and it is our duty not to encourage these stupid ...


spec's persistence question
Sun, 27 Apr 2008 01:20:11 MDT
Hi,
I read this rule in persistence spec's.
 quote:

The behavior is unspecified if mapping annotations are applied to both persistent fields and
properties or if the XML descriptor specifies use of different access types within a class hierarchy.

 
that's mean we can't specified the annotation one for field, and the next one for property.
 
when we specified the annotation for field need to specified all unfading the annotation at fields.

Which application server?
Thu, 24 Apr 2008 07:48:02 MDT
Hi,
 
I have (finally) decided to go for the SCBCD certification.
I am completely new to EJB technologies, but not to JEE (JSP, JSF, some ADF).
 
After going thru some of the posts in this forums, I decided to use OReilly's EJB 3.0 (5th Edition) for my preparation. I also plan to go thru the specs as that proved very useful when preparing for the SCWCD exam.
 
While waiting for the book to arrive, I'd like to install an Application Server in order to experiment and practise. The 'problem' is that I am uncertain to which one to use: JBoss, Glassfish, Sun Application server 9.1, Oracle Application Server, Apache Geronimo 2.1 (is it EJB 3.0 compliant?), etc.?
 
With SCWCD preparation the choice was ...

I've passed SCBCD today with 90% in exactly 1 hour. If I had checked my 5-6 marked questions, maybe the result would be a little better, but I was sure I would pass the test.
 
The test is really not hard - there are no detailed questions from API (method arguments, return types etc.) like in SCJP.
 
You must *understand* beans' lifecycle (callback methods), transaction mechanism (only 6 transaction attributes) and exceptions (not hard, just 
think on which layer it is and if it is remote or local). It is necessary to *learn* by heart not so many methods' definitions from only 5-6
