Hi there,
"In tomcat C:\jakarta-tomcat-4.0.1 is a docroot or C:\jakarta-tomcat-4.0.1\webapps is a docroot?"
DOCROOT = C:\jakarta-tomcat-4.0.1\webapps\yourapp\
DOCROOT is the root directory for your weba app.

regards
Sean
Hi all,
I have found out that there is a book called "CramSession's Object-Oriented Analysis and Design with UML : Certification Study Guide"
which is an ebook and has been published for some time ( since 2000 ).
However I haven't seen a posting that mentioned this book at all.
I guess that tells how bad the book is ?? or somehow not known to developer community?
thanks
Sean
haha
Barry,
That howto in Apache site is no good.
They have a "HelloWorld" example that does not work and apparently the author wanted to removed that example.
What is so bad is that HelloWorld example was "THE ONLY" from the scratch example that one can find on the web.. I searched for 2 days and couldn't find anything good.
Any book or url on the topic would be very very very helpful..
thanks
Sean

Hi all,
Question ID :1021101705605
4) Which of the following is NOT true about custom tags?
a)A custom tag can access JavaBeans declared in the session scope
b)A custom tag can access implicit objects of the JSP page in which it occurs
c)A custom tag can access all the user-defined objects in all the scopes
d)A custom tag can access all the custom tags declared in the same page
e)A custom tag can access all the custom tags in which it is nested
Answer is d) but how come is c) true ??
I thought unless the user-defined object is put into one of the "scope object", you can't access it from custom tag since custom tag uses PageContext to do that.
1) I know that servlet's request SCOPE is supported by "ServletRequest"
2) I think JSP's request SCOPE is also supported by "ServletRequest"
3) I think JSP's request implicit variable is refering to "HttpServletRequest"
Am I right about 2 and 3 ?
Thanks
Sean
Hi all,
If no request comes from the client for more than "session timeout" period, then session definitely invalidated ???
thanks

Hello all,
Question ID :995989678581 from Hanu's book mock exam.
If an HttpSession is migrated, Java's Serialization mechanism is used to do so.
this is not true it says.. why?
If the question was
"If an HttpSession is migrated, Java's Serialization mechanism is ALWAYS used to do so"
then I would say false though.
Thanks in advance
Sean
Hi all,
Servlet's request scope is "implemented" by ServletRequest.
But what about JSP's request scope ?
and JPS's request implicit object?
HttpServletRequest or ServletRequest ?
thanks
Sean
Hi,
P148 Q1 What do these deployment descriptor elements relate to? select one correct answer:
<security-constraint>
<login-cofig>
<security-role>
a. Authorization of web application
b. Data integrity of web application
c. Authentication of web application
d. Singing of web application
answer is c but ... I think it both a and c.
what do you think?
Thanks
Hello Peter,
Thanks for your post.
So what that phrase means is
"even though readObject() and writeObject() is not guaranteed to be called, your attribute will go through something much like Serialization."
Thanks
Sean
Hi all,
Servlet Spec says
"Developers are not guaranteed that containers will call readObject and writeObject methods on
session attributes if they implement them, but are guaranteed that the Serializable closure of their attributes will be preserved."
I don't get what it means by "guaranteed that the Serializable closure of their attributes will be preserved"
Anyone can clarify ?
Thanks in advance
Sean
Hi all,
Are BodyTagSupport.getOut and BodyContent.getEnclosingWriter
return the same OBJECT? ( not asking about if the return type is the same or not )
Thanks in advance
Sean
Don,
I don't think you can since <login-config> is the element that specifies what authentication mechanism to use. and it is the direct child of <web-app> and the cardinality is 0 or 1.
So for a given application you can only use one authentication mechanism.
Correct me if I am wrong anyone.
Thanks
Sean
