Re: [topbraid-users] sml:CreateSPINResultSet using sml:ConvertStringToSPINRDF

Jamal; It could be a bit simpler than you think.  Attached is an example that will take a query as an argument and return the results in JSON format.  The key to the example is to name the argument to match the local name of the query property - in this case selectQuery.

This is also set up as a Web service, so you can find all of the first names in our kennedys model with the following URL:

localhost:8083/tbl/sparqlmotion?id=testSPINxlation&selectQuery=SELECT DISTINCT * WHERE {?s kennedys:firstName ?o}

This assumes the TBC-ME personal server.  For a TBL server, replace the server name accordingly.

Let us know if that helps you any.

Hello,

In a SPARQL motion script (TBCME Version: 3.6.2.v20120921-1501R , Windows 7), based on input parameters, I have built a SPARQL query string and I want to run this query.
I wanted to use sml:ConvertStringToSPINRDF to generate a sp:Select instance and use the uri of this resource as input argument of sml:CreateSPINResultSet. But I have an error message saying "Error: java.lang.IllegalArgumentException: Node must be either literal or a SPIN query or a SPIN template call". I don't understand the reason. Could you help me ?

Thanks in advance
Jamal
