Re: [Bigdata-developers] Can't format SPARQL result with Turtle.

[Bryan T. <br...@bl...>]

Conneg is handled here:
https://github.com/blazegraph/database/blob/64bb8ca92eb063d45d68ec920a34b5321b80e2fe/bigdata-core/bigdata-sails/src/java/com/bigdata/rdf/sail/webapp/BigdataRDFContext.java
at around line 2470.  Not sure what is going on offhand.  Can you set
a debugger on this and see what is happening?

} else {
// Use whatever was specified by the client.
final List<String> acceptHeaders = Collections.list(req.getHeaders("Accept"));
acceptStr = ConnegUtil.getMimeTypeForQueryParameterQueryRequest(
req.getParameter(BigdataRDFServlet.OUTPUT_FORMAT_QUERY_PARAMETER),
acceptHeaders.toArray(new String[acceptHeaders.size()]));
}

// Do conneg.
final ConnegUtil util = new ConnegUtil(acceptStr);
