Hello Mr Westenthaler, I have configured Apache Stanbol. I can access services using http://localhost:8080. I tried to do steps that you described, and I did not have a problem with step 2, but I am not sure that I did step 1 correctly.
When I issued command like this one: curl -X POST -H "Content-Type: application/rdf+xml" --data "@acm_ccs-proton_rdfxml.owl" http://localhost:8080/entityhub/entity I got response: *curl: (52) Empty reply from server* This file which I am trying to upload is almost 1MB big. It should not be a problem with memory. Do you have any idea what could be a problem? How I can check that I did the job correctly?
