------------------------------
Summary: SERVICE execution does not propogate BINDs within the
SERVICE clause
Key: JENA-422
URL: https://issues.apache.org/jira/browse/JENA-422
Project: Apache Jena
Issue Type: Bug
Components: ARQ
Affects Versions: Jena 2.10.0
Reporter: Rob Vesse
Assignee: Rob Vesse
Fix For: Jena 2.10.1
This was originally spotted thanks to a user question at
http://answers.semanticweb.com/questions/21759/using-bind-and-service-in-fuseki
The basic problem described there is that a BIND used within a SERVICE clause
appeared to have no effect.
I was able to reproduce this with a minimal Fuseki setup using an in-memory
dataset containing a single triple and the following query:
SELECT * WHERE { SERVICE <http://localhost:3030/ds/query> { ?s ?p ?o . BIND(?o
AS ?x) } }
I have a unit test for Fuseki that demonstrates the behaviour as well. Under
the debugger I can see that the BIND clause is not included in the query string
that gets sent to the remote service hence the lack of values for the BINDed
variable.
