HI, The modification didn't help me to update the ontology remotely.The program just display the names in the console window with no updation.
I think some where I am doing wrong. I have a doubt regarding the owl file . Currently I have per2.owl in two locations . One is in the root directory "D:\fuseki-0.2.2\per2.owl" for executing the command " ruby s-put http://localhost:3030/ds2/data default per2.owl" . And the second one is inside the "D:\fuseki-0.2.2\pages" directory also. when I removed the per2.owl file from the D:\fuseki-0.2.2\pages it shows the error. " Exception in thread "main" com.hp.hpl.jena.shared.DoesNotExistException: http://localhost:3030/per2.owl"; So confusing when calling "UpdateExecutionFactory.createRemote(ur," http://localhost:3030/ds2/update";);" which file will update or is it just in-memory updation. Should I need to write extra function for updating the ontology. similar like model.write(...)
