> Project: Marmotta
> Issue Type: Bug
> Components: KiWi Triple Store
> Affects Versions: 3.4.0
> Environment: marmotta-3.4.0-SNAPSHOT; Tomcat7 - executed with: mvn
> tomcat7:run
> Operating System: Linux
> Reporter: Dietmar Glachs
> Assignee: Dietmar Glachs
> Priority: Trivial
> Fix For: 3.4.0

> CONSTRUCT-Sparql-Request fails with "no result format specified or
> unsupported format".
> In SparqlWebService.select an extensive request header parsing is done to
> determine the best content type to use for the response.
> Reason: in the above environment - the method
> {code:java}
> List<String> acceptHeaders =
> EnumerationUtils.toList(request.getHeaders(ACCEPT));
> {code}
> does not produce a list with each requested accept header, instead a list
> with a single entry containing all accept headers is created - example below:
> {code:java}
> "application/n-triples;q=0.7, text/plain;q=0.7, application/rdf+xml;q=0.8,
> application/xml;q=0.8, text/turtle, application/x-turtle,
> application/trig;q=0.8, application/x-trig;q=0.8"
> {code}
> This string is then further parsed with
> {code:java}
> List<ContentType> acceptedTypes =
> HttpMarmottaUtils.parseAcceptHeaders(List<String>)
> {code}
> where the string is split into tokens. Problem: the leading space after each
> comma (",") is not stripped!!
> Solution: in MarmottaHttpUtils.java, method "parseContentType", each token
> should be trimmed - line 132.
> {code:java}
> String mt[] = c.trim().split(";");
> {code}
> Just provided the patch to "develop" branch
