Hi,

I don't use EJB at work but I think it's a good technology to know. (and be certified in)

I heard that many enterprises want to remove EJB from their product, is it true that EJB is called to disappear?

I would like to have your opinion on that!

Thanks.

Hi,

I used whizlab simulator exam for the Web Component Exam and it was really really helpful, no doubt I will buy for Business Component Exam.

Hi,

The RI is included in the J2EE 1.3, so you don't have to search for the RI on sun's website.

Did you see the 'note' from the wickedlysmart.com website?

I don't really know if it's your problem but you can't name the method like the interface name. Your method should be like getTheMessage() instead of getAdvice() because 'Advice' is in the interface name.

I got it to work fine, seems to be another classpath error... I have to add the working directory in the classpath..

I found the problem :

In the book, it's {CLASSPATH}:AdviceAppClient.jar

but in WinXP, it's %CLASSPATH%AdviceAppClient.jar

So that problem is now resolved but I got an exception in thread main.. NoClassDefFoundError AdviceClient..

I try this example from Head First EJB and when I compile AdviceClient.java I got an error telling me that headfirst.* package doesn't exist. It's the same thing for javax.ejb..

I added lib/j2ee.jar to the classpath and always the same things... somebody can help me?

Thanks,

Hi,

I am also interested in the second edition of the book, what's the approx. release date?

Thanks,

SCJP 1.4
SCWCD 1.3.

It's what I thought too..
But in Whizlabs, it says that if we set it to FALSE, the service() method will be THREAD SAFE...
It's not logical this way.
So is it Whizlabs who's wrong or what?

Hi,
I don't understand the reason why we have to set the page directive isThreadSafe to false if we want the service method to be thread safe.
I thought that we have to set it to true...
Someone can explain it to me?
Thanks.
Eric

Thanks a lot!

Hi,
How can I resolve the compilation error :
INSERT INTO Paiement VALUES(seq_noPaiement.nextval, noLiv, myDate);
dbms_output.put_line('NoPaiement : ' || seq_noPaiement.currval);
The error occurs when I do the put_line with seq_noPaiement.currval...
I also tried to do this :
myVar := seq_noPaiement.nextval;
INSERT INTO Paiement VALUES (myVar, noLiv, myDate);
dbms_output.put_line('NoPaiement : ' || myVar);
But it didn't work too...
So I don't have any idea about how to resolve this ... ???
Thansk,

How can I create an executable file (using JBuilder4) for a Java application? I want the file to be run on many computers.
Thank you!
