[jira] [Commented] (STANBOL-170) Unwanted Exception thrown on
console
[ https://issues.apache.org/jira/browse/STANBOL-170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13144954#comment-13144954 ]
Paolo Castagna commented on STANBOL-170:
----------------------------------------
This is because Clerezza's JenaParserProvider.java [1] does not have "RDF/JSON" support, therefore it defaults to "RDF/XML".
So, you are using an RDF XML parser to parse RDF/JSON.
RDF/JSON support has been only recently added to Jena (and it has not been released yet):

> When sending data to the stanbol enhancer, I get the attached exception on my console. I use the full launcher with the Zemanta and OpenCalais engines.
> Though I retrieve annotations I think the exception should at least be catched and replaced by an appropriate message. This can look "scary" for first-time users.
> The command I execute:
> curl -X POST -H "Accept: application/rdf+json" -H "Content-type: text/plain" --data "The Eiffel Tower." http://localhost:8080/engines
