Unable to connect with fuseki SPARQL endpoint through Sesame connector

Finally solved, with the tips that Andy S provided in the fuseki mail list. If you want to have a look at the whole discussion check http://markmail.org/message/bootb7tlrg35luou

The problem was that the Sesame repository and the repository ID were not aligned with Fuseki. For my sesame connector the sesame repository always hangs from /repositories so I had to take it into account when defining the dataset in Fuseki.

Therefore, I launched fuseki with the dataset: /repositories/ds

  $ java -Xmx1200M -jar fuseki-server.jar --update --mem /repositories/ds
    18:35:45 INFO  Server               :: Dataset: in-memory
    18:35:45 INFO  Server               :: Dataset path = /repositories/ds
    18:35:45 INFO  Server               :: Fuseki 0.2.5 2012-10-20T17:03:29+0100
    18:35:45 INFO  Server               :: Started 2012/11/20 18:35:45 CET on port 3030

and in the piece of code to connect to fuseki I created the repository with a repositoryID of ds/sparql

 public static void main(String[] args) {

        String endpointFuseki = "http://localhost:3030/";
        String repositoryID="ds/sparql"

    try {
        HTTPRepository endPoint = new HTTPRepository(endpointFuseki, repositoryID);
        endPoint.initialize();

        RepositoryConnection conn =  endPoint.getConnection();
        try {
            String sparqlQuery = "SELECT * WHERE {?X ?P ?Y} LIMIT 10 ";
            TupleQuery query = conn.prepareTupleQuery(QueryLanguage.SPARQL, sparqlQuery);
            TupleQueryResult result = query.evaluate();

            while (result.hasNext()) {
                // do something linked and open
            }
          }
        } finally {
            conn.close();
        }
        catch (Exception e) {
              e.printStackTrace();
          }
}
