Thank you. That is much nicer than my penciled notes on my white board. It will make it easier to memorize.

Again, Thank you.

[amar kasar]

hey Micheal John

thanks, its realy a nice list to prepare.....

[Boobalan Jegathesan]

Hi..

Good job..I Appreciate your work

[Joe Harry]

How did you get this idea of putting this down here?? Awesome man! keep it up. It should be really useful for all those studying for SCWCD.

[vikas bala]

Awesome Work Michael
I appreciate that.
Marvelous !!

[Joe Harry]

What combinations of questions can we expect in the real exam regarding the web.xml file?? Any idea guys??

[Christophe Verré]

I don't know why I've always found the nice diagrams in the spec easier to remember than a big web.xml sample

[Krishna R Seelam]

Very useful. Great work.

[Victor Maehira]

First of all, congratulations for you, ranchers! This web.xml sample has been very useful! I wonder if the child tag within <security-constraint> should be <web-resource-collection> instead of <welcome-resource-collection>. Or both exists?!
And also, shouldn�t the resource name be <web-resource-name> instead of <welcome-resource-name>?!
Thanks!

[Srinivasan thoyyeti]

Thanks for this. I am about to prepare one.

[khushhal yadav]

Hi Victor

I am agree with you as XML Schema says:

- <!-- ****************************************************
-->
- <xsd:complexType name="security-constraintType">
- <xsd:annotation>
<xsd ocumentation>The security-constraintType is used to associate security constraints with one or more web resource collections Used in: web-app</xsd ocumentation>
</xsd:annotation>
- <xsd:sequence>
<xsd:element name="display-name" type="j2ee isplay-nameType" minOccurs="0" maxOccurs="unbounded" />
<xsd:element name="web-resource-collection" type="j2ee:web-resource-collectionType" maxOccurs="unbounded" />
<xsd:element name="auth-constraint" type="j2ee:auth-constraintType" minOccurs="0" />
<xsd:element name="user-data-constraint" type="j2ee:user-data-constraintType" minOccurs="0" />
</xsd:sequence>
<xsd:attribute name="id" type="xsd:ID" />
</xsd:complexType>
- <!-- ****************************************************
-->

And DTD also verifies that

<!ELEMENT security-constraint (display-name?, web-resource-collection+, auth-constraint?, user-data-constraint?)>

Khushhal

[Chandra Bhatt]

Telling you seriously, I never imagined that much web.xml I would have
to learn/ (BTW I have learned now). Seeing them at a place collectively
is really awesome experience.





Nice effort!

Thanks,

[Cristiano Sganzerla]

Im drunked and remember all of the web.xml file.

Im really prepared for the exam !!!

I think the unique error in the web.xml schema posted by Micheal John is the
'web-resource-collection' that was corrected by Victor Maehira and khushhal yadav.

I was wondering if this child tag could appear in the exam since i didnt see in the HFSJ, just in Exam Study Kit book.

<variable>
<name-from-attribute>var</name-from-attribute>
<scope>AT_BEGIN</scope>
<variable>
<dynamic-attributes>true<dynamic-attributes>

Talking about the topic.

PERFECT POST !!!

Hi Cristiano

<variable>
<name-from-attribute>var</name-from-attribute>
<scope>AT_BEGIN</scope>
<variable>
<dynamic-attributes>true<dynamic-attributes>

I am not sure whether it can appear in exam or not.
But it's really something good to know. And also not difficult to grasp.

Moreover, it's not a part of web.xml. It's a part of tlds.
It's concerend with scripting varibles. And define their lexical scope.
There can be three values of it: AT_BEGIN, NESTED, AT_END.

Khushhal

[Cristiano Sganzerla]

Thanks !!!

[Padma priya Gururajan]

Hi,
Thanks.

[Frank Knoll]

... and

<function-signature>String displayTest(java.lang.String)</function-signature>

should be

<function-signature>java.lang.String displayTest(java.lang.String)</function-signature>

[nav katoch]

Thank you very much everybody for your contribution and time. This will help everybody. It is a handy reference.

Thanks, Naveen.

[Frank Knoll]

and there could be context parameters in the web-app:

<context-param>
    <param-name>webmaster</param-name>
    <param-value>[e-mail]</param-value>
</context-param>

[Tony Ding]

nice job, thanks

[Vimal Panchal]

Thanks to All,

Nice one.

[John Pearson]

Very nice listing! I wish I had had that a couple of months ago when I was preparing for the exam.

[Jay Palaniappan]

Thanks for the sample web.xml. I took the liberty of correcting some typos and added few more items in the web.xml. I also validated in RAD (Rational Application Developer) to make sure it doesn't have any more errors. Hope its useful to others...

[Abhra Kar]

10000 thanks to you

[Mitch Miller]

To Jay and all,
Thank you Jay for posting and validating.
You mentioned using "(Rational Application Developer)" for xml validation.

Sadly, I do not have RAD available.

How can I validate web.xml using Java?
e.g. once I put 2 error pages together, like this:

<error-page>
<error-code>404</error-code>
<location>/missing.jsp</location>
<error-code>500</error-code>
<location>/error.jsp</location>
</error-page>

Java ignored 404/missing but used 500/error and I wasted lots of time trying to figure out why it caught 500 errors, and ignored 404 errors.

How could I find an error like this?

Thanks, Mitch

I think we should specify form-login-page and form-error-page only if the auth-method has value 'FORM'.Please correct me if i have misunderstood.

Thanks,
