Hi Christian
No it's another container, a Camel route on a Karaf instance exposed as a REST-service. I'm pretty sure this is due to the handling of error in HttpPayload.java I'm still on BaseX 7.9 if that matters. But when i checked the code i peeked into the master branch.

Hi Johan,
Thanks for bringing this up. I currenly try to find out if this is a server-side or client-side issue. Is the web service you are talking to (on port 9595) a BaseX instance, too?
Thanks in advance, Christian

Hi
I have a REST service that communicates details about any errors that
occurs
during execution via a an XML-payload in the response body.
I have noticed that the http-module ignores the content-type header of
the
response if the status-code is > 399. Then it is flagged as being in
error
and in HttpPayload this line forces the content type of the body to text/plain
HttpPayload.java // error: use text/plain as content type final String ct = error ? TEXT_PLAIN : utype != null ? utype : contentType(ctype);
Overriding the content type via the override-media-type attribute of http:request doesn't help either in this case.
Is there any special reason that error response-bodies are handled in
this
way? To my knowledge it is very common that REST services provides error information by sending it in the response body.
I guess that changing the default behaviour might break existing implementations. But perhaps an additional attribute in the http-request could flag that the media-type of the content-type should be used even
with
error-responses. Or perhaps via an additional option in the http:send-request() function.
Exampel of request and response where this error occurs.
Request: http:send-request(<http:request override-media-type="application/xml" href="{'http://localhost:9595/sequencegenerator/objectInstanceId/' ||
'0'}"
method="get"/>)
Response: <http:response xmlns:http="http://expath.org/ns/http-client"
status="400"
message="Bad Request"> <http:header name="nbrOfIds" value="0"/> <http:header name="typeOfId" value="objectInstanceId"/> <http:header name="Transfer-Encoding" value="chunked"/> <http:header name="breadcrumbId" value="ID-2013M-2-local-61198-1416819131884-37-54"/> <http:header name="User-Agent" value="Java/1.7.0_45"/> <http:header name="Accept" value="text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2"/> <http:header name="Content-Type" value="application/xml"/> <http:header name="Server" value="Jetty(8.1.15.v20140411)"/> <http:body media-type="text/plain"/> </http:response><faultResponse><errorMessage>number of ids
