Failed to build dataset from description (service name: sparql): java.net.ConnectException: Connection timed out

[lyne1991]

Hi,
I downloaded xlwrap and started the server, but i got the error whose script is reported below. The server starts but i can't use the SPARQL endpoint nor SNORQL ( i get an internal server error) . I tried modifying etc/pubby-base-config.ttl by putting the following values for the given properties.
conf:webBase http://localhost:8900/;
conf:sparqlEndpoint http://localhost:8900/sparql;
Is there anything else i might need to change for configuration?
