Sharing my experience with you

[alzamabar]

Hi guys, as I've done during SCBCD, also while studying for this exam (as now I'm approaching the end, finally, eheheh), I wrote a document which I could refer to in order to have a quick reminder of things like interfaces' signatures, web.xml elements, security, etc. I thought I could share with you this document which you will find at the following address:

SCWCD Reminder - At the home page, click on the 'SCWCD Reminder' link


The site is active from 9.00am to 11.00pm London time.

Please send any comments or insults for mistakes (there will certainly be some) at: mtedone at jemos.co.uk

Good luck,

Marco

it's very nice Marco

Thanks for sharing..!! i'm preparing for the exam right now..!! If you could, could you please list all the mock exams which you took through the web??
I really do appreciate it..!!
Thanks in advance Marco

It's quite simple really! I used softSCBCD for SCBCD and softSCWCD for SCWCD.

If you run a Google search for those two exams, you will find the link. Additionally, I used the mock exams available on this site and you can refer to the following URL:

JDiscuss

to find some nice and free mock exams.

Good luck,

Marco

thanx for the information Marco

Very nice check list marco. I'm starting my prep for this. Got the good list at right time. Thanks!! Can you also tell me how long it took to feel that you are in pretty good shape along with your efforts? This is just to have a rough estimate for myself.

Thanks once again...

[Ranjit Jana]

Thanks Marco,

This will surely be of help.

Excellent collection and would surely help everyone going for the Exam. It would be better if the complete method signatures are given in Servlet API. Similarly the following needs correction:

<!--        S E C U R I T Y                  -->
 
  <security-role>
    <role-name>Admin</role-name>
    <role-name>Member</role-name>
    <role-name>Guest</role-name>
  </security-role>
  

There should be separate <security-role> element for each role.

Thanks,

Durga

According to web-app DD and p632 of HFS&J either way is OK

[Jose Esteban]

According to Figure SRV.13.16 in Servlet spec 2.4 (page 145), the only correct way is to use only one <role-name> per <security-role>.

So I think there's a mistake in HFSJ.

I don't think so .
I tried the way mentioned in HF and it works fine

[Francois Roland]

Great job !

Thank you.

I think there is one thing to correct:

Brief Roadmap:

19) The HttpSession - related listeners.

I'm pretty sure that there is another listener that doesn't have to be registered in the deployment descriptor: HttpSessionActivationListener.

I didn't say it doesn't work. I only say that it isn't correct according to the JSP 2.0 specs.

I don't know. I think the Servlet 2.4 specs are a little confusing. The say in SRV.10.3.2:
"Listener classes are declared in the Web application deployment descriptor using the listener element."

Which, I understand, means that all of the listeners must be declared in the DD. But later, in SRV.15.1.10, the specs say:
"Events of this type are either sent to an object that implements HttpSessionBindingListener when it is bound or unbound from a session, or to a HttpSessionAttributeListener that has been configured in the deployment descriptor when any attribute is bound, unbound or replaced in a session."

which seems to indicate that HttpSessionBindingListener doesn't need (have) to be declared in the DD.

I really would appreciate any explanation.

What HFSJ say is that:
"...HttpSessionActivationListener must be registered in the DD, since they are related to the session itself, rather than an individual attribute placed in the session"

What about ServletRequestListener or ServletRequestAttributeListener? I think they must be declared in the DD, but I dont know it for sure.

Yes, confirmed. The HttpSessionActivationListener and HttpSessionBindingListener don't need to be declared in the DD. I know it because my colleague took the exam last week.

It really depends on few factors:

1) If you work
2) If 1 was true, if the company you work for wants things by yesterday 'cause' of business
3) If you are healthy
4) If you are ready to give up drinking (if you drink at all) alcohol for the study period (believe me, it's harder than it seems)
5) If you are free to do what you want in your spare time

My answers to the above are:

1) Yes
2) Yes
3) Yes, but after 13-14 hours at the office, I feel the tiredness
4) Yes, except on my first year marriage anniversary, where I took my wife to a Russian restaurant and I had a bloody mary and a special reserve 'pure vodka'
5) Yes

With the above answers, is taking me now 6 months to get prepared. I'm preparing to get the best from the exam, not just a certification.

Hope it helps.

Following the specs, it seems that Durgaprasad is right, therefore I updated the document. However, my interpretation of the thing is that there should be more than one role in a security-role element, otherwise why to bother to create a security-role name? They could simply accomodate more than a single role-name element. Certainly it would have saved us a lot of opening and closing tags

[P. Dunn]

Following the specs, it seems that Durgaprasad is right...

Yes. In the spec, I looked looked up
<!ELEMENT auth-constraint (description?, role-name*)>
not
<!ELEMENT security-role (description?, role-name)>

I can't find anything to corroborate that a HttpSessionActivationListener need not be in DD. HFS saqys the opposite. Could your colleague have gotten it wrong?
Could you give a reference? Anyone?

BTW : Thanks Marco. Nice summary.

Hi Marco,

your doucment is really helpful...
I guess, u forgot to include <servlet-mapping> element.


Thanks

Unfortunately I can't. I have to trust my colleague or...lose a mark on the exam

So far I was thinking that those two are the only two listeners which are implemented by classes destined as session attributes, for one goal or another, and that was the reason. Pretty soon I'll start the softSCWCD exams and I'm sure there there will be a reference.

Could you tell me where?

Towards the end of the document there is a DD containing mostly all the elements (not all the optional ones!). Additionally, in the roadmap today I added the three kind of servlet mapping:

Exact match
Directory match
Extension match

[janne s]

Hi! Marco,

is the link updated that u posted here...
i don't c any changes in the document related to mapping
except for ' Defining initial parameters for a JSP'

If u make any changes leave a message here...


Thanks,

Oopps, sorry, you are right. I must have deleted the <servlet-mapping> element by mistake. Now I inserted three different servlet-mapping elements.

Thank you for the hint.
