hello,
I am running my input SPARQL query and you want to insert two and two
intenger and String. The problem I have with the introduction of variables
the type String, once I run it gives me the following error:
*Exception in thread "main" com.hp.hpl.jena.query.QueryParseException:

Print variable "querys" out after construction and see the error.
If you put newlines in the query string, it'll be easier to read.
