IIRC things have moved on since then. How do things stand relative to
Jena 2.10.0?

I extended QueryEngineHTTP to achieve what I had described:

This is GPL3 licensed which is a blocker to incorporating your
suggestion. If Jena 2.10.0 does not do what you want, please could you
open a JIRA and attach a suitably licensed version?
Thanks

I think endpoint (authentication) config is useful in a broader scope
than SERVICE only.

Hey,
I'm running SPARQL queries on endpoints with HTTP Basic
authentication, and am looking for a convenient way to manage and
configure the credentials.
Currently I've implemented a simple registry that checks endpoint URIs
against a map and sets the credentials using
QueryEngineHTTP.setBasicAuthentication().
Recently however I came across query Context configuration:
http://jena.apache.org/documentation/query/service.html
That seemed exactly what I needed, but there is a problem: it doesn't
seem to work with basic QueryEngineHTTP? Am I right to assume that
srv:serviceContext only works with explicit SERVICE endpoints?
Any reason why the approaches cannot be unified and
QueryEngineHTTP.setBasicAuthentication() would use the Context? It is
executing the query against some service after all (even if it's not
explicit SERVICE). What class(es) would I need to extend to achieve
this?
The code I tried on ARQ 2.9.2 (endpoint and credentials are bogus):
Context sparqlContext = new Context();
sparqlContext.put(ARQConstants.allocSymbol("http://jena.hpl.hp.com/Service#";,
"queryAuthUser"), "xxxxx");
sparqlContext.put(ARQConstants.allocSymbol("http://jena.hpl.hp.com/Service#";,
"queryAuthPwd"), "yyyy");
Map<String,Context> serviceContext = new HashMap<String,Context>();
serviceContext.put("http://dydra.com/graphity/repository/sparql";,
sparqlContext);
ARQ.getContext().put(ARQConstants.allocSymbol("http://jena.hpl.hp.com/Service#";,
"serviceContext"), serviceContext);
...
QueryEngineHTTP request =
QueryExecutionFactory.createServiceRequest(endpointURI, query);
if (log.isDebugEnabled()) log.debug("SPARQL Context: {} ",
request.getContext());
request.execConstruct();
I see the credentials in the debug output:
symbol:http://jena.hpl.hp.com/Service#serviceContext =
{http://dydra.com/graphity/repository/sparql=symbol:http://jena.hpl.hp.com/Service#queryAuthPwd
= yyyy
symbol:http://jena.hpl.hp.com/Service#queryAuthUser = xxxxx}
but the serviceContext doesn't seem to have effect since I'm getting
13:21:54,149 TRACE HttpQuery:242 - Exception in exec
HttpException: 401 Unauthorized
You need to sign in or sign up before continuing.
at
com.hp.hpl.jena.sparql.engine.http.HttpQuery.execCommon(HttpQuery.java:431)
where QueryEngineHTTP.setBasicAuthentication() used to work fine. Am I
doing it wrong?
Help appreciated :)
