Hi friends,
I'm happy to inform that I cleared SCBCD with 80% today morning.
I just read for one month(Just read the HFEJB) .no other book.
Actually I started my preparation in Feb,but could not study for one month in between as we have moved to a new place.
HFEJB was very helpful.
just did the mock exams available on-line.
Thanks to all my friends here .

Hi folks,

1 Which two are guaranteed capabilities of EJB 2.0?
a). Local home interfaces for messages driven beans.
b). Dirty detection mechanisms to reduce memory footprints.
c). Run-as security identity functionality.
d). The JDBC 2.0 extension.
e). Read only CMP entity beans.

i think c and d are correct.

Thanks Rahul and Frederic,

But I've one more question regarding the "Bean provider's responsiblities" 1 and 2 in the page 542.
Is the given code a "bean's code " or "the client's code"?
If it is a bean's code ,how can we catch a RemoteException in the code??
Thanks in advance

Hi,

I have a question regarding 'throw EJBException' from a business method.
In P.543 of HF EJB, Bean Provider's responsibilities (3), it says: " If your business logic catches an exception the client is not expecting, wrap it and rethrow it as an EJBException".

what about Remote clients???
Do we have to throw RemoteException???
thanks in advance

Hi friends,
I think
change an existing customer's phone number operation is suited both for home and component interface as we can use find method of home to get an existing customer and then update it.
Is it correct?

Delete all customers in Plesantville operation is suited for home interface only.I guess as component interface methods are only used for single entity operations not batch operations .Is it correct?

One more question is
Can we delete multiple entities by using remove(Handle h) or remove(Object key) methods of home interface??
I guess we CANT.
Thanks in advance

Hi friends,
I'm trying to understand <security-identity> tag.
Let's say that a client calls Bean A,and Bean A in turn calls Bean B ,you want the Bean B to think that someone else is calling.
Then we use <run-as > tag right???

So, when do we use <use-caller-identity>???
I think we use this tag , if you want the Bean B to know that Bean A is indeed calling ,not (eventhough Bean A was called by the client initially)someone else.


What my question is in <use-caller-identity/> tag Is the caller here the client or the Bean A.Which caller's identity is used??

I've gone through all the old threads but did not find a good explanation .

thanks for any inputs in advance
