HI,
Thanks for all the help from this forum. Thanks to the authors of HFSJ book. Just for fun, I read that book.It impressed me so much! Then I wanted to take the exam and passed with 82%. I prepared for 2 months.
Regarding exam: there are 6EL questions, 6 Design Pattern questions,4JSTL, 1 question on Filters,3 questions on simpletags,<ejb-local-ref>,<env-entry> questions also there.
I think this exam is a bit easier than scjp.
Thanks again.

Consider the tag handler class shown in exhibit.
What will be printed when the above tag is used as follows in a jsp page:

Hello <mylib:mytag> World!</mylib:mytag>

Code

public class MyTag extends TagSupport
{
public int doAfterBody()
{
try
{
pageContext.getOut().println("In doAfterBody()");
}
catch(Exception e)
{
}
return SKIP_BODY;
}
}
they gave answer is Hello.

I think answer is Hello World
because there is no doStartTag() and default is skip_body, so it goes to the doEndTag() and default value is EVAL_PAGE so World has to print.

Can anybody explain me ?
Thank you

Thanks for replies.

1:If you give -ve value to this element <load-on-startup> what is the result?

2:<body-content>tagdependent</body-content> answer in the mock exam is it must implement the BodyTag interface. is it correct? can't we use in TagSupport classes ?


3:HFS mock exam Q-11
${map[map-index]
if you don't give quotes in the[]operator container looks for that name of attribute. so here there is map-index attribute. why can't container can't get this value?

4 what is the default value of the attribute's rtexprvalue in tagFiles?

5 what is the resylt in 2 conditions:
<session-timeout>0</session-timeout>
<session-timeout>-2</session-timeout>

6: what is the difference between encodeURL() and encodeRedirectURL()

thanks
