Hi Mikalai,

thank you very much for your reply. It is already very helpful for me.

In your Study Guide for Web Services 6 you had a detailed list of stuff, which is potentially an exam topic.

Do you have the same thing for this exam!  Just a detailed TOC. That would be very very very helpful!!!

Thank you in advance.
Salah Lejmi

Congratulations.

It will very interesting to know how many questions per topic are on the exam. This information is on right side of your score report.

Could you please send it to this thread.

Thanks.

Salah.

Hi Reza,

First of all: Great Book, i decided today to continue my preparation for SCBCD with it. (fortunately i am at the beginning)

One suggestion: would you please provide a possibility to submit own errata and also provide a download link to these "unconfirmed errata". I saw some other books doing this. I find it very useful.

After reading your book, maybe i will make some other suggestions if any.
(und sure if your book is not yet on market )

Salah,

Are you using EJB 3 remoting by accident or on purpose? The problem you are having indicates an RMI connectivity issue, possibly because of a firewall, but it could also be some kind of weird network misconfiguration.

The "from" syntax definitely won't work unless you are using Hibernate. Even then, it's not a good idea...I am shocked the Bill Burke book would include such code. I certainly did not catch that when I read it myself.

The code you have posted is fine otherwise. The problem is elsewhere.

Thanks,
Reza

P.S.: What you are using is called JPQL, not "EJB query language". That refers to EJBQL in EJB 2.x Entity Beans.

First of all, thank you much for the reply.
Second, it was in fact in the oreilly book in many sections:
- 9.1. Query API:
Query query = entityManager.creatQuery( "from Customer c where c.firstName='Bill' and c.lastName='Burke'");
- 25.1.6. FlushModeType Behavior
- I saw it also elsewhere in the book

but it is as you said not a valid syntax for JPQL (thank you for the explanation) and because it was a bit strange to me, i looked in the unconfirmed errata of this book. And in fact it was inside as a mistake. (because of this mistake so much trouble and testings but anyway, i am learning ). The unconfirmed errata text contains the right answer:
select c from Cab c where ...
I tested this syntax and it worked fine. Thank you all for your help.

Originally posted by Christophe Verre:
String s = "from Cab c where c.name = '"+deckName+"' ";
Where is the SELECT ?

i read this syntax in the oreilly book.

i tried also with "select from ..." and "select * from ..." but still getting error message.

how would you write the query in the ejb-syntax ?
[ October 31, 2008: Message edited by: Salah Lejmi ]

hi, i have an entity session bean (service bean) with following method:
public Cabin getCabinByName(String deckName) { char queryArt = 'n'; // n for SQL native, j for ejb query language /// trying with EJB Query Language if (queryArt == 'n') { String s = "select * from CABIN c where c.NAME = '"+deckName+"' "; Query query = entityManager.createNativeQuery(s, Cabin.class); // notice this // query.setParameter(1, deckName); Cabin cabin = (Cabin) query.getSingleResult(); return cabin; } else { // following does NOT work (do you know know why? String s = "from Cab c where c.name = '"+deckName+"' "; Query query = entityManager.createQuery(s); // query.setParameter(1, deckName); Cabin cabin = (Cabin) query.getResultList().get(0); return cabin; } }

The Cabin class is defined as follows:
@Entity(name="Cab") @Table(name="CABIN") public class Cabin implements Serializable{ @Id @Column(name="ID") public int getId() { return id; } ...

I am getting following console output
Entity Service greeting You: Salah after creating cabins ... trying to get a cabin by its name ...

Does anybody have precise statistics about SCJP, SCJD, SCWCD, SCBCD, SCJDWS and SCEA ??

Thank you All.
