Trying to use DatasetAccessor. I am getting the following error. Where
could I start to troubleshoot this error. Is this a problem with my
config.ttl file? I am trying to run the following command :
DatasetAccessor datasetAccessor =
DatasetAccessorFactory.createHTTP("http://localhost:3030/ds";);
Model model = datasetAccessor.getModel("http://example.org/#serviceA";);
Exception in thread "main" org.apache.jena.atlas.web.HttpException: 403 -
