SPARQL QUERY STRING VARIABLES
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:
Lexical error at line 1, column 331. Encountered: " " (32), after :

Print the query out:
System.err.println(querys);
You will see that you get the whole query on a single line, which
is very hard to read, and the error message will just tell you
line 1 (there is only one line) and probably a character position
like 79 or 113 which is hard to relate to the line.
You need line-breaks in the query string, so FOR EXAMPLE the line
" ?m gr:quantitativeProductOrServiceProperty ?s . " +
becomes:
"\n ?m gr:quantitativeProductOrServiceProperty ?s . " +
so that `?m gr:quantitativeProductOrServiceProperty ?s .` comes
out on a new line.
Do that to all your querys lines and then print the querys. Not
the code -- the query string. The error will probably be obvious.
Chris
PS don't put subject lines in all-caps. Don't past code into your
message with all those extra *s -- it makes the code harder to read.

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

Put newlines in your query. (At the beginning or end of your strings.)
Print it out or look at it in an editor, especially if it can show
line numbers.
Then you can see where the problem is & it will likely be obvious
how to fix it.

kernels of metal with rueful respect, "ought to prove pretty potent in the
pinch. I just wish I knew which ones they were."
