Federated query

[Kamalraj Jairam]

Hello,

     if i create federated query like

    CONSTRUCT 
  { ?s <http://localhost/target#patientId> ?o .}
WHERE
  { SERVICE <http://localhost:8084/processor/webresources/rs/sparql>
      { ?s <http://localhost.com/traleerdf/csv#ID> ?o }
    SERVICE <http://localhost:8084/processor/webresources/rs/sparql>
      { ?s <http://localhost.com/db#patient_patientid> ?o }
  }
LIMIT   10

   will jena always send a select query to the endpoints?

   I’m getting the following exception i execute this query

   om.hp.hpl.jena.sparql.resultset.ResultSetException: skipToHead: Unexpected 
tag: {http://www.w3.org/1999/02/22-rdf-syntax-ns#}RDF
