Hi miquel
great work.. i too am planning to give test 252. Could you please give me the details of your preparation. I dont have websphere experience will that be a problem? both the infocentre and the redbooks have a lot of material.. seems impossible to learn all of it.. is it really that difficult?

Hi All,

I have a question about the "bean things" that can be done at various stages in a session bean life cycle.

Ref page 216 HFEJB- if you see, we can't force transaction rollbacks or find if a transaction has been set for a rollback but we can get transaction references and call methods on them in the ejbCreate() ejbActivate() ejbPassivate and ejbRemove() methods.

The question is why is it that we can perform transaction related operations for BMT beans and not for CMT beans in these methods?

cheers!

Dear all,

I am preparing for the SCBCD 1.3 exam, i am using windows xp. I have downloaded j2e sdk 1.3.1 Could someone please tell me what procedure i need to follow to run the examples.

I tried to follow the steps given in the book but it dsnt seem to work.. i think i have something wrong in the installation... can anyone help me with some sort of guidelines for installation and all steps starting from download to execution..

i know this might be a little much but i'm sure many are facing a similar problem

Thanks,
Nik
Dear all,

Im giving a shot at Test 252: WebSphere Application Server Network Deployment V6.0; aiming at changing my job profile.

The unfortunate part is that I don�t have any Websphere experience, not even theoretical knowledge. I have cleared SCJP 1.4 and SCBCD

Im hoping someone here will help me with the following questions

oIs not having hands-on experience that big a deal?
oDo I really have to read through and remember the four redbooks (coming nearly up to 4000 pages)
oIs there any study group that I can join?
oAre there any good free mocks? If yes, where can I get them?

Looking forward to your opinion�

Cheers

thanx that solved a lot of stuff... i guess just one further question will a reference become null only if it is assignedthe value null explicitly as in

strInst=nulll;

or are there other ways that makes refrences null???

to reframe the question is the dog free only if i unleash it or there are other elements that may help break the shackles ??

hi.. im not too sure about this but.. i think wat u really want to ask is that

if instance varisbles are initialized to default values y not local variables too

rit??
as i see it.. when an object is created.. a default constructor is called if another constructor is not defined.. this default constructor gives default values to instance variables.
well i tell completely y.. but this is something that happens
im not sure though and by the looks of it my explanation is not complete so if anybody can elaborate then it will be great
i guess the next question to be asked is watif in a non default constructor if i initialize only some of the instance variables then what??

public class constructor{
int a,b,c;

constructor(){
a=0;
b=1;
//i dont initalize c then does c get a default value 0??
}

}

the answer to your question might be hidden in the answer to mine...
