doubt with res.sendRedirect

To support clients without redirect capability, HttpServletRsponse.sendRedirect() method writes a short response body that "
contains a hyperlink to the new location"

Is this valid, cos i dont see anything like this in the API, and "clients without redirect capability?" meaning browsers which dont support redirect??

Thanks,
Sangeetha

SIMPLE DOUBT FROM MOCK EXAM

From which interface(s) do you need to implement the methods if you want to create an iterative tag without body content? [Check all correct answers]
1. Tag
2. LoopTag
3. IterationTag
4. TagSupport
5. BodyTag

the site says the answer is 1,3.

the tag interface doesnt have the doAfterBody() , i think 3&4 is right but he has asked only for interfaces. whats the right solution.

Thanks

does preparation need API specs

Hi,

Iam planning to take up the scwcd1.3 exam and iam aware that the hanumant book is the best one for that...are the methods that have been discussed in the book as per the objectives enough for the exam or do i need to go thro the api and know some more mtds that are there in each interface as well.

Thank you,
Sangeetha

page directive

Hi Shan,
U can use page directives to import classes, create custom error pages and also include pages..to include the pages at complile time u have to use the include directive
<%@ include file="path of the file u want to include" %>
here the code becomes part of the generated servlet so any changes to the jsp are reflected only when modified and recompiled.
to include a file at runtime u have to use the include action
<jsp:include page="path of the file u want to include" flush="true" />
here the included file never becomes part of the generated servlet(for the JSp) so any change to the included file is displayed in the jsp the next time the page is requested..
hope this helps, and i think there can be more than one page directive, iam not sure tho...hopefully some one will clear that up for both of us.

JSP

Custom Error Page

Hi,
Iam aware that u have to include the page directive in the page where the error is generated so that it is forwarded to a jsp error page which has the directive "isErrorPage="true"...but doesnt seem to be working...
my html is in "c:\tomcat\webapps\app-name\subfolder" with the page directive before the <html> tag.
<%@ page errorPage="/subfolder/show_error_page.jsp" %>
my error page is in the same folder too named "show_error_page.jsp" with the foll code
<html>
<body>
<%@ isErrorPage = "true" %>
this is a custom error page
<p><i> <%= exception %> </i>
<body>
</html>
iam not sure where the mistake is...Greatly appreciate the help

simple doubt

hi,
iam was trying out a simple example where iam trying to display the multiple choices in a list box with jsp....it gives the following error

Generated servlet error:
[javac] Compiling 1 source file
C:\Tomcat 5.0\work\Catalina\localhost\murach\org\apache\jsp\email4\show_005fmusic_005fchoices_jsp.java:60: illegal start of expression
<
^
1 error
this is the JSP code...i cant figure out where the mistake is...the string array variable and the syntax seems to be correct
<body>
<%
String firstName = request.getParameter("firstName");
String lastName = request.getParameter("lastName");
String emailAddress = request.getParameter("emailAddress");
%>
<h1>Thanks for joining our email list <%=firstName%></h1>
<%
String[] musicchoice = request.getParameterValues("music");
for(int i = 0; i < musicchoice.length; i++)
{
%>
<%= musicchoice[i] %> <br>
<%
}
<%>
</body>
