connection refused from jena fuseki

Question

I'm trying to READ my data from localhost jena fuseki with the SPARQL query service on the internet like this one http://factforge.net/sparql this is my query

select * where { 
service <http://localhost:3030/blibiografi/sparql>{
    ?s ?p ?o .}
limit 10

. but unfortunately I get an error message like below.

Error 500: error
Query evaluation error: Connect to localhost:3030 [localhost/127.0.0.1] failed: Connection refused (Connection refused) (HTTP status 500)

can i pull data directly from jena fuseki directly with query or not? or is there a service where i can upload my graph ontology and perform read and update operations on it?

Answer 1

If your problem is related to encountering a "Connection refused" error while attempting to use the FactForge query service to query your local data, it's important to understand that this error is likely occurring because Fuseki is only running on your local machine and is not accessible from FactForge.

In this situation, the solution is to use the Fuseki Web interface on your local machine, as it will allow you to query your dataset directly. You've already identified the correct Fuseki Web interface URL, so you can access the Fuseki UI by navigating to http://localhost:3030/#/dataset/<datasetname>/query in your browser. This approach should resolve the "Connection refused" error, as it bypasses the need to access FactForge and instead interacts with your local Fuseki instance.
