Hi,
The Stanbol Entityhub does not have an RDF to HTML serializer. Because
of that it responds with
"The registered message body writers compatible with the MIME
media type are:
text/html; charset=utf-8"
If you send an RDF mime type (e.g. text/turtle) as Accept header it
should work just fine.
Try to add "&header_Accept=text/turtle" to the end of your URL when
requesting an Entity via the browser.
e.g.
http://localhost:8080/entityhub/lookup?id=file:///C:/Users/Acer/Documents/Semantic/Stanbol/EntityPerson/Marry.Smith.rdf%23Marry_Smith&header_Accept=text/turtle
best
