Re: Looking for a more restrictive type of SPARQL validator

Hi Andy,

thanks for the fast reply and thank you very much for the hint.
I'll send a copy of this to our programmers then. Just originally assumed the error resided inside the SPARQLing (I'm just the markup-guy… ;-) ) 

Nonetheless, here comes the stacktrace (short version):

Hi all,

for a content inclusion project I recently wrote the following SPARQL
query, had it validated at http://sparql.org/query-validator.html and
tested locally with Twinkle 2 –— all doing perfectly well.

Though, just as soon as this very same query runs on our server,
JENA/ARQ gives me a


com.hp.hpl.jena.query.QueryParseException: Syntaxfehler


Which is, why I'm looking for a query validator, which evaluates SPARQL
more similar to the way JENA/ARQ do— internally and which provides
errors meaningful enough to properly act upon.

Any help, links, tools etc. are very welcome!!
http://sparql.org/query-validator.html is running Jena (it is a Fuseki server).
Parse errors return the line number and column of the error (being an LL parser, they are usually right!) 

You have a different error - what's the stacktrace?

Andy



Best,
