Hi Ranchers,
I recieved a free voucher to sit for the actual SCBCD 5 exam from prometric.

Thanks a ton for the support from Evelyn

Hi Ganesh,

Hi Guys,
I have sent a mail to Evelyn stating the same. Lets see how things unfold..

Hi Ranchers,
After a month long preparation for SCBCD 5, I went to the Prometric center(NIIT, Chennai, India) to give the exam. Guess what??? They said that SUN has filtered the candidates who had registered for SCBCD beta based on some criteria(which they themselves were not aware of..) and I was not listed to take up the exam.. Infact I registered for the exam on the very first day, Nov 24th. Just wanted to checkout whether anybody else had a similar experience.

Regards,
Malan

Thanks Rajan, never knew that

Hi Ranchers,
Can @AroundInvoke be used with Entity beans?

Malan

Hmm... Assuming that am calling setRollbackOnly() in a CMT bean whose business method has a transaction attribute, NotSupported or Never, then an exception should definitely be thrown coz there is no active transaction available for rollback.

Hi Ranchers,
Am not able to discern the semantic difference between EntityManager and
PersistenceContext. Any help in this regard would be greatly appreciated.

Thanks in advance,
Malan.

Hi Ranchers,
Is there any difference between the following methods in javax.transation.UserTransaction

rollback() and
setRollbackOnly()

Thanks in advance,
Malan

Hi Ranchers,
Since EJB 3.0 specification supports EJB2.1 also, will the SCBCD 5 exam test us on the older spec? Will there be a clear demarcation between both the versions in the exam?

Thanks in advance,

Hi guys,
I got it working :-)

changed the following import statement
import javax.ejb.PreDestroy;
to
import javax.annotation.PreDestroy;

Hi ppl,
I tried compiling a session bean with a @PreDestroy annotation. It gave me a 'cannot find symbol' for class PreDestroy. I checked the javaee.jar and found that only PrePassivate and PostActivate are present. Can anyone help me out? I have given the code below:

import javax.ejb.Stateless; import javax.ejb.Remote; import javax.ejb.Remove; import javax.ejb.PreDestroy; @Stateless @Remote(HelloRemote.class) public class HelloEJB implements HelloRemote { public String sayHello() { System.out.println("Hello"); return "Hello"; } @Remove public void removeBean() { System.out.println("Remove"); } @PreDestroy public void destroyBean() { System.out.println("Destroy"); } }

Thanks in advance,
Malan
