------------------------------------------
Summary: a QueryEngineHTTP doesn't handle the returned content
type after an execModel() call.
Key: JENA-466
URL: https://issues.apache.org/jira/browse/JENA-466
Project: Apache Jena
Issue Type: Bug
Components: ARQ
Affects Versions: Jena 2.10.0
Reporter: ArthurVaisse-Lesteven
When executing this simple piece of code :
public class test {
public static void main(String[] argv){
String request = "Ask from <http://example.com#graphe> where
{<http://example.com#ProofOfConcept> ?p ?o}";
String endpoint = "http://localhost:3030/shield/query";;
Query query;
try{
query = QueryFactory.create(request);
}
catch(Exception e){
throw e;
}
QueryEngineHTTP query_engine = new QueryEngineHTTP(endpoint,
query);
try{
SPARQLResult spqlr = new
SPARQLResult(query_engine.execDescribe());
}
finally{
query_engine.close();
}
}
}
I got the following exception :
Exception in thread "main" com.hp.hpl.jena.query.QueryException: Endpoint
returned Content Type: application/sparql-results+xml which is not a valid RDF

com.hp.hpl.jena.sparql.engine.http.QueryEngineHTTP.execModel(QueryEngineHTTP.java:275)

com.hp.hpl.jena.sparql.engine.http.QueryEngineHTTP.execDescribe(QueryEngineHTTP.java:251)
at
com.hp.hpl.jena.sparql.engine.http.QueryEngineHTTP.execDescribe(QueryEngineHTTP.java:248)
at test.main(test.java:29)
The same error occurs when I change the endpoint to a Sesame repository. So I
think the problem come from the code who receive the repository response and
check content type. He probably wait another content type.
