Hi David To me it looks like that the SPARQL endpoint of dbpedia does not return valid JSON as results of a SPARQL CONSTRUCT query.
I think in the error.log file (/sling/logs/error.log) should provide some additional information (such as the query sent to "http://dbpedia.org/sparql";. You could e.g. use your browser to see the returned results yourself. If you provide such information I could also make some tests and help. best Rupert On Mon, Aug 29, 2011 at 11:20 AM, Bertrand Delacretaz <[email protected]> wrote: > Hi David, > > On Mon, Aug 29, 2011 at 10:58 AM, David Riccitelli > <[email protected]> wrote: >> ...I'm having an issue with Stanbol (r1153390), the analysis of a text fails >> 100% of the times with an exception.
