Rupert Westenthaler commented on STANBOL-175:
---------------------------------------------
Parsing the ID of an Symbol to http://localhost:8080/entityhub/mapping is
supposed to result in an error, because this method only accepts IDs of
EntityMappings.
To lookup (possible multiple) mappings for an symbol one has to use curl
"http://localhost:8080/entityhub/mapping/symbol?id={symbolId}";
However the reported error (java.lang.IllegalArgumentException) as well as the
http error code are very misleading.
A request like this should rather return 404 Not Found

> 1) Lookup an entity using the entityhub/symbol/lookup endpoint:
> curl
> "http://localhost:8080/entityhub/symbol/lookup/?id=http://dbpedia.org/resource/Paris&create=true";
> In the JSON result you get the ID, e.g.: "id":
> "urn:org.apache.stanbol:entityhub:symbol.1265dfa5-f39a-a033-4d0a-0dc0bfb53fb7"
> 2) Get the mapping for this ID using entityhub/mapping endpoint:
> curl
> "http://localhost:8080/entityhub/mapping?id=urn:org.apache.stanbol:entityhub:symbol.1265dfa5-f39a-a033-4d0a-0dc0bfb53fb7";
> 3) You get the following error message:
