Re: [Owlim-discussion] OWLIM/Sesame and Query parsing

Hi Laurent,

since you are building a single jar out of few other (if I got it right) - 
could you check the contents of the MATE-INF/service subfolders of the final 
jar  for all the parsing service specific definitions - text files named by 
the service interface with lines stating specific interface implementations
i.e. specifically for a file named 
META-INF/services/org.openrdf.query.parser.QueryParserFactory with
contents:
org.openrdf.query.parser.sparql.SPARQLParserFactory
if you merge several jars where there is a such file, the last one will 
override the one from other jars

hope this is of some help

regards,
Damyan

Thanks for your response.

I do same and it works in a JunitTest. However, when I test it in my
global application which link jar and create a JAR of all my classes,
i get the previous Exception.

JAR are in classpath and the problem seems to be the same that the
link I previously referenced.

RepositoryConnection conn = null;
       boolean result = false;

       try {
           conn = this.repository.getConnection();

           try {
               result = conn.prepareBooleanQuery(language, 
query).evaluate();
           } finally {
               conn.close();
           }
       } catch (Exception e) {
           e.printStackTrace();
       }

       return new Boolean(result);

Where language is QueryLanguage.SPARQL and query is equals to "ASK { ?
s ?p ?o }"

Laurent

Hi,

how do you parse the query? The following code works just fine ...

  BooleanQuery q = 
repository.getConnection().prepareBooleanQuery(QueryLanguage.SPARQL,  "ASK 
{ ?S a ?C} ");
  System.out.println("result is "+ q.evaluate());

regards,
Damyan

Dear all,

I am trying to parse and to execute a SPARQL ASK query in my 
application. When I do that, I get the following exception :

org.openrdf.query.UnsupportedQueryLanguageException: No factory 
available for query language SPARQL

However all the JAR are in the classpath. It is a known problem ?

I have searched on the web and I have found a similar subject but  it 
dates back to 2007 :
http://www.openrdf.org/forum/mvnforum/viewthread?thread=1410

The solution is to use a more recent Sesame version which corrects   this 
bug. So i have tried with the Sesame 2.3-pr1 version but the   problem is 
always the same.

Does someone has an idea ?

Thanks.

Kind Regards
Laurent
