Hi Dirk,
this is the output I get when using curl (same as Poster) with response
status 400:
> curl -I http://localhost:8984/exists?message=vvv
HTTP/1.1 404 No function found that matches the request.
DBG: message was vvv
Content-Type: text/html;charset=ISO-8859-1
Cache-Control: must-revalidate,no-cache,no-store
Content-Length: 1442
Server: Jetty(8.1.14.v20131031)
whereas if I change the return status to 500
> curl -I http://localhost:8984/exists?message=vvv
HTTP/1.1 500 Message wasn't yes!
DBG: message was vvv
Content-Type: text/html;charset=ISO-8859-1
Cache-Control: must-revalidate,no-cache,no-store
Content-Length: 1391

Just in case the issue could be related to the combination OS/JAVA:
I'm using Ubuntu "12.04.4 LTS, Precise Pangolin" and running Openjdk 7.
Thanks again and regards,
M.

Hallo Marco,
I tried to reproduce this now, but couldn't manage to do so. curl shows

There was no difference when I used another response code (except of
course it returned that return code then).
Are you sure you are setting the correct HEAD request in this Firefox
addon? Of course also this addon could do something incorrectly with the
HEAD request, so you might want to try with another tool like curl or wget.
If this doesn't help, did you try the latest snapshot (which I used now)?
Cheers,
Dirk

Sorry Dirk,
I should never write mails while in a hurry.
I'll try to restate my question.
This is the code snippet I wanted to use:
declare
%rest:path("/exists")
%rest:HEAD
%rest:query-param("message","{$message}")
function page:exist(
$message as xs:string)
{
try{
if ($message = 'yes') then ()
else error(xs:QName("err:ERR"), "Message wasn't yes!")
} catch * {
<rest:response>
<http:response status="400" reason="{$err:description}">
<http:header name="DBG" value="{'message was '|| $message}"/>
</http:response>
</rest:response>
}
};
It should return a 400 (Invalid request) whenever an exception is raised
in the implementation of the function. I understand for empty sequences
but it should not impact on the test now.
The point is that if I change the 400 into any other status code I get a
proper response.
With 400 (as it's correctly written in the code now) I get always "404
No function found that matches the request" as the response.
I'm sending my requests with Firefox Poster and they look just like
this: "http://localhost:8984/exists?message=vvv";. For these requests I'm
getting the stacktrace and the responses you can see at the end of the
email.
If I rewrite my query to return for instance 404 or 500 (instead of 400)
I get the same stacktrace but a correct HTTP response "HTTP/1.1 404
Message wasn't yes!".
I hope I could express myself better this time.
Thank you,
M.

Hello Marco,
I can't really follow. What 400 status code are you talking about,
because I can't really see one in the code.
I couldn't really test it because I didn't manage to tell curl to send
form data and using HEAD at the same time (something like curl -I -F
message=yes ... didn't work, help appreciated).
But your if statement (returning the empty sequence) will result in the
following error:
[BASX0003] HEAD method must return a single 'restxq:response' element.
Although I didn't test in in the combination, if I either use HEAD or
the form param it worked. So could you please clarify in which case this
code did work and what error you are experiencing?
Cheers,
Dirk

I've the following simplified RESTXQ code snippet that I use with basex

};
This is always returning HTTP status 404 with reason "No function found
that matches the request".
This happens only for the 400 status code. Any other status code I use
to set behaves as expected including 404 itself.
Any hints?
Thank you.
Regards,
Marco.
