Hi Christian, It worked after I made modification to my code based on HTTPConnection.mediaType(). Many thanks for pointing me to the right direction. Andrew On 26 July 2017 at 22:08, Christian Grün <christian.gruen@gmail.com> wrote:

Hi Andrew,

This is how you can request the value of output:media-type:

import org.basex.io.serial.SerializerOptions; .... SerializerOptions sopts = proc.qc.serParams(); String type = sopts.get(SerializerOptions.MEDIA_TYPE);

As the media type can be empty, you can additionally take advantage of the HTTPConnection.mediaType() function [1], which will always returns a media type (provided that you have the basex-api classes embedded):

import org.basex.http.HTTPConnection; import org.basex.io.serial.SerializerOptions; .... SerializerOptions sopts = proc.qc.serParams(); response.setContentType(HTTPConnection.mediaType(sopts).toString());

Hope this helps, Christian

Hi,

Is it possible to get the value of "output:media-type" through QueryProcessor?

I am currently trying to use BaseX as a view renderer for a Spring MVC application. The view is rendering fine using embedded BaseX. However, I can't figure out how to get the "output:media-type" value from the XQuery so that I can set the response header during runtime. I can set the content-type through the controller in Spring. But I would rather not have to do it in two separate places. Below is the relevant code snippet from the view renderer.

try(QueryProcessor proc = new QueryProcessor(query, context)) { Iter iter = proc.iter();

//response is HTTPServletResponse response.setContentType(????);

try(Serializer ser = proc.getSerializer(response.getOutputStream())) { for(Item item; (item = iter.next()) != null;) { ser.serialize(item); } } }

Any suggestion?

Thanks Andrew
