Passed SCWCD upgrade (310-084) 92%

Fri, 9 May 2008 12:58:59 MDT

This morning I passed the upgrade from SCWCD 1.4 to 5.
The test was 50 questions in 2 1/2 hours, more that enough time.
More design patterns than I expected (10-15%). As I read here, deployment descriptors and EL were definitely emphasized.
I mostly used "HFSJ 2nd ed", "SCWCD Study Companion" by Lyons, and Marcus Greens' web site.
If you have the time to read both books, I suggest HFSJ first and Lyons second. I found HFSJ is good at getting the basic ideas (the dumb Kung Fu movie stills helped me nail the choose-when-otherwise syntax), and then I had enough context to hang the details in Lyons. Lyons is very good and very complete.

Thanks to all the authors.

Options:
1. Any resources that this servlet might hold have been released.
2. The servlet container time out has exceeded for this servlet instance.
3. The init() method has been called on this instance.

there's an element run-as at the servlet element of the deployment descriptor.
does anyone have any clue what is it for?
servlet 2.4 specification says: "the run-as" element specifies the identity to be used for execution of a component. could somebody say what does it means in english?

What should I do next???

Thu, 8 May 2008 08:22:55 MDT

Hi

I finished studying HFSJ twice.
Then from last 3 days I am taking Marcus Exams once a day(total 3 exams).
I got 73%, 83% and 83% in the exams. With this I got some confidence.

What to do next(Shall I go through the enthuware's simulator?)
I am planning to take HFSJ exam 3 days before exam.

CX-310-081 vs. CX-310-083

Thu, 8 May 2008 02:38:54 MDT

I am currently looking towards taking my next Sun certification exam. I am looking at the SCWCD exam and I am still undecided between two available CX-310-081 and CX-310-083. When looking at the exam objectives for both exams on the SUN web site there isn't much of a difference. The only differences are in section 7, i.e. Building JSP Pages Using the Expression Language (EL). In this case the following two points are only in CX-310-083:

- Given a scenario, write EL code that uses the following operators: aritmetic operators, relational operators, and logical operators.
- Given a scenario, write EL code that uses a function; write code for an EL function; and configure the EL function in a tag library descriptor.

Reg : SCWCD 1.5

Wed, 7 May 2008 23:58:54 MDT

Dear All,

I m planning to take SCWCD 1.5 exam. I have HFSJ 1.4 book. Is it enough to take 1.5 exam. Also guide me like what are all the steps to be followed. I am not good in EL and Design patterns. Can you please send me the links for Design patterns and EL.

Thanks in advance,
P.Prasanna.

Confusion with design patterns

Wed, 7 May 2008 11:24:53 MDT

Hi all,

There are only six design patterns (Business Delegate/Service Locator/Transfer Object/Intercepting Filter/MVC/Front Controller) mentioned in HFSJ book. But in some mock exams, other two design patterns came up which are Data Access Object and Value Object. My question is whether we should know these two babies or not and where we can get the details about them.

Is the HFSJ (2nd version) really 100% covered for SCWCD 5.0
Thanks alot.

Doubt in Mock question

Tue, 6 May 2008 07:50:49 MDT

Hi,
I found this question in Marcus Green's mock exam paper-1.

52. Given a JSP page with the following code, which of the following options would result in the output of red?

<%
java.util.HashMap hm = new java.util.HashMap();
hm.put("apple","red");
request.setAttribute("apple",hm);
%>Choose at least one answer.
a. ${apple.["apple"]}
b. ${apple.apple}
c. ${apple["apple"]}
d. ${apple['apple']}

I have a doubt, whether requestScopes attribute "apple" can be accessed directly by name?
I think this question is wrong. Please confirm.

EL :: calling functions on attributes

Mon, 5 May 2008 23:48:48 MDT

HFSJ 2nd edition mock exam Page 848 question number 41

<c:if test="${account.personalChecking}">Checking that fits your lifestyle</c:if>

As far as I understand the above EL will call getPersonalChecking() function rather than isPersonalChecking()
And I think there is no way to access any functions other than getters on attributes/Properties, when we use EL ??

If there are no NO <http-method> elements it means that NO HTTP Methods are allowed by ANYONE in ANY role

p. 660
There's an example where no <http-method> is specified. There's a commentary: We left off <http-method> so that NO HTTP Methods are accessible by ANYONE except Admin (there's a <auth-constraint> with this role coming after <web-resource-collection>

Mon, 5 May 2008 01:32:45 MDT

Hi,

Cleared SCWCD1.5 yesterday 1.5 with 85%. As per mentioned in the earlier posts the exam has been made tricky. The questions and the corresponding answers are given in a tweaked manner where one has to read the options and the question carefully. When I read some questions for the first time, it was Hey whats this. However after giving it a second reading it was quite nice.

I feel its very important to know the API throughly, the return type and the parameters. The security related questions were tough for me, scored lowest in it. I tried out Marcus Green and Enthuware 1.4 mock exams, never had any questions for security close to what appeared in exam. Also scored less on Custom tags.

Conflicting Security Constraints

Sun, 4 May 2008 07:36:34 MDT

Let's say you have two different security constraints on the same resource:

<auth-constraint/>
which should allow access to no one.

and

<auth-constraint>
<role-name>*</role-name>
</auth-constraint>
which should allow access to everyone. (or you could have no auth-constraint listed at all).

Do ALL users get access to this resource or do NO users get access to the resource. HFSJ is not clear about this.

Thanks

tagdir

Sat, 3 May 2008 10:10:31 MDT

Hello all,

I'm confused as to the purpose of the tagdir attribute in the taglib directive.

On page 492 of HFSJ 1.4, it gives an example:
<%@taglib prefix="mytags" tagdir="/WEB-INF/tags" %>

On page 499, it describes the 4 places the container will search for .tag files. So what exactly is the purpose of the tagdir if the container will only search 4 specific locations?

Thanks
