If I create a url with a context relative path (e.g. /x/y/z) and the I use

So given this...
c:url var=aURL value=/x/y/z/
${aURL} Get resource at z
c:import url=${aURL} var=xml /
The link in href attribute in the browser is a valid url, but the url
attribute in the import tag is not. I get a file not found exception for
/x/y/z. Import seems to want to lookup a static resource (html page for
example) located on the file system and not open connection to some network
resource. I am assuming from the name (import) that this is probably what is
expected.
No, what you're describing works exactly correctly for me -- the
URL is accessed, and the rendered output, not a file, is fetched.
What value does ${aURL} display?

But if you're using a 2.4 deployment descriptor -- check what's at
the beginning of your application's web.xml -- upgrading to JSTL 1.1
is as simple as downloading and replacing a couple of jar files...

%@ taglib uri=http://java.sun.com/jsp/jstl/fmt; prefix=fmt %
c:set var=someCount value=61/
c:set var=counter1
fmt:formatNumber type=number
maxFractionDigits=0 value=${ someCount / 3 }//c:set
${counter1}
|
fmt:setLocale value=en_US/
c:set var=counter2
fmt:formatNumber type=number
maxFractionDigits=0 value=${ someCount / 3 }//c:set
${count}
Most browsers will show
20 | 20
but user-agents not providing a Locale via an Accept-Language header
like wget (and Amaya) retrieve
20.332 | 20
If I manually add a header to wget, e.g.
wget --header='Accept-Language: en-us,en'
then the result is '20 | 20'
Is this proper behavior or a bug? I realize it's probably a little
suspect using formatNumber to do quick'n'dirty rounding, but it's
for presentational purposes, so... :-)

Re: Formatted date not returning
Keith wrote:
I'm trying to return a formatted date from an Oracle database. I format the date in the

function, JSP is acting like nothing is returned. If I take the function out and just
select the column as normal, it outputs but with the full TimeStamp (which I don't want).
I don't know Oracle, but if this was MySQL I'd say you need to
assign an identifier to your returned result, something like
sql:query var=resource_list
SELECT
TO_CHAR(dob, 'DD-MON-')
TO_CHAR(dob, 'DD-MON-YYY') AS thisDOB
FROM ccevs_resource_registry
/sql:query
..and then call it as
c:forEach items=${resource_list.rows} var=resource_row
c:out value=${resource_row.dob} /
c:out value=${resource_row.thisDOB} /
Untested, but FWIW!

Re: Getting request URI with JSTL

Why does a call to request.getServletPath(), which is that JSTL
call above, give me a path to a _JSP_?
Because a JSP page /is a servlet/*, it's just one that's compiled
by the container. And you're asking for the path of the *current*
servlet, by definition, so if you've got a dozen forwards chained
together, you'll get a dozen different results from the expression
above as you move through the chain.
*cite: JSP 1.2 Specifiction
JSP.1.2.4 Translation and Execution Steps
The JSP page is translated to create a servlet class, the JSP
page implementation class, that is instantiated at request time.
/cite
If I call request.getServletPath() from within a _servlet_, then
I get something like '/Action.do', which is what I needbut I
need it in the JSP.
You're asking for what was the first request in this chain? and
AFAIK there's no object that stores that. Someone may correct me on
that :-) but, in the meantime, what I'd do is use a Filter to set a
request attribute with the original request URI for use anywhere in
the request processing chain.

Any thoughts? Does your original full example from the book define
