Hi ,
So What is final conclusion considering the SCWCD exam ? Is WEB-INF Directory mandatory or not ?
Thanks everyone for your responses , particularly Christophe & Bert for paying attention to this particular thread. When posting the question, I didn't imagine that it would be such a big topic of Discussion.

Hi,
If no method is specified , default implementation of service() will internally call the doGet() method. Hence B is correct.

Thanks a lot everyone!
I got it . Class loading means JVM will allocate some memory for the class. It will happen only once. Where instantiating will happen everytime object of that clas is created.

Thanks for your response !

Hi Ranchers,
As I understand, JSP pages can execute without WEB-INF directory. Hence is it mandatory for WEb application to have WEB-INF directory ?

Thanks

Hi Ranchers,
I have some silly but significant doubt related to Servlet Life cycle

What is the difference between Loading the servlet & instantiating the servlet ?

Heartly Congratulations , varun

THanks Ankit & Ulf for the reply. I'll try to find out details & will get back to you for more clarification
Thanks ,

Hi Bennet,
I got it. Thanks for clarification. PageContext.getOut() will return the current JspWriter stream being for response. In doStartTag(), we are sending some part of response & in doAfterBody() , we are sending the remaining response.
Many thanks for your kind attention.

Hi Bennet,
Thats correct ! Your code seems to be much simpler. Thanks a lot for sharing !
I just have one doubt . We are setting the font color in doStartTag() using the JSPWriter out object. As I understand we are using the same instance of JSPWriter object ( through which we have set the font ) in doAfterBody(). Please let me know whether my understanding is correct !

Hi,
For displaying the body content in RED ,

Define the attribute for the tag lets say color

Define the tag with Body & attribute in TLD file

Extend your tagHandler class from BodyTagSupport Class,

write the corresponding getter method for that attribute

Return the EVAL_BODY_BUFFERED constant from doStartTag()

Overrride the setBodyContent() & doInitBody() methods, that will be called after the doStartTag()

Give the implementation of doAfterBody() as follows

Get the JSPWriter object using bodyContent.getEnclosingWriter()
Get the body string using bodyContetn.getString();
Get the value of color attribute using the getter();
Format the body using the color value
Send the formatted content to the JSPWriter using the out.print()

Hope this helps.. Please let me know if there is some diferent appraoch.

Hi Ranchers,
I know that Head method works exactly like the get method but it only returns the HTTP header information without any body.
However I have never seen any example till now in which doHead() is overrriden.
Hence Could you please let me know
1) How to print the HTTP Header information using doHead() i.e.what whould be defintion of overriden doHead() ?
2) How to make a HEAD request from the browser ?

Many thanks is advance !

I have read in Hanwant Deshmukh SCWCD book that " a SimpleTag's body must not contain scripts - no declarations, expressions, or scriplets. Hence for SimpleTAgs's body , you cant set the <body-content> as JSP ..

My question why is this restriction in SimpleTag while we can use the same in custom Tag ?

Many Thanks in advance !
