Andy Seaborne commented on JENA-707:
------------------------------------
Your config works for me (loaded with tdbloader, query with API and
QueryExecutionFactory) with the current version of Jena and TDB.
* {{mkdir -p quad-store/live}}
* {{tdbloader --desc tdb.ttl D.trig}} (D.trig has one triple and one quad)
* Code as below:
{noformat}
Dataset ds = TDBFactory.assembleDataset("tdb.ttl") ;
Query query = QueryFactory.create("SELECT * { { ?s ?p ?o } UNION { GRAPH ?g {
?s ?p ?o } } }") ;
QueryExecution queryExecution = QueryExecutionFactory.create(query, ds) ;
QueryExecUtils.executeQuery(query, queryExecution) ;
{noformat}
I don't have access to OSX.

> Key: JENA-707
> URL: https://issues.apache.org/jira/browse/JENA-707
> Project: Apache Jena
> Issue Type: Bug
> Affects Versions: Jena 2.11.1
> Environment: OSX 10.9.3 (Mavericks)
> Reporter: Rick Moynihan
> Priority: Minor
>
> When using the Jena API and TDBFactory.assembleDataset("config.ttl") if the
> storage location path contains a hyphen it prevents querying at least via
> QueryExecutionFactory.
> e.g. the following Assembler config fails, causing all queries to return
> empty resultsets:
> {quote}
> @prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> .

> [] ja:loadClass "com.hp.hpl.jena.tdb.TDB" .
> tdb:DatasetTDB rdfs:subClassOf ja:RDFDataset .
> tdb:GraphTDB rdfs:subClassOf ja:Model .
> <#live> rdf:type tdb:DatasetTDB ;
> tdb:location "quad-store/live" ; # change to suit your local
> installation
> ja:context [ ja:cxtName "arq:queryTimeout" ; ja:cxtValue "10000,10000"
> ] ;
> tdb:unionDefaultGraph true ;
> .
> {quote}
> But changing tdb:location to "quadstore/live" works.
