[jira] [Commented] (JENA-220) General purpose SPARQL query engine
uses W3C is uses online RDFa Distiller - so not usable behind a firewall
[ https://issues.apache.org/jira/browse/JENA-220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13226953#comment-13226953 ]
Andy Seaborne commented on JENA-220:
------------------------------------
Fuseki does not ship with or provide RDFa distilling itself. How are you invoking this functionality? Is it by e.g. SPARQL FROM clause? If so, that's where the distiller needs to be set.
If you are behind a firewall, and want Java to call out through it, try setting the proxy details when you invoke java:

The W3C service is pyRdf.

> Components: Fuseki
> Affects Versions: Fuseki 0.2.1
> Environment: I runnung Fuseki version 0.2.1-incubating-SNAPSHOT (Build date: 2012-03-03T05:07:05+0000) under Windows 7 Professional: java -jar fuseki-server.jar --mem /dataset

> Fix For: Fuseki 0.2.1

> When I'm using http://localhost:3030/sparql in Fuseki - I get an wrong results when working behind a firewall. The reason is simple: RDFa is distilled using the W3C service http://www.w3.org/2007/08/pyRdfa/ which you can see in the console or when HTTP sniffing. So the sofwtare is not usable in an intranet solution or behind firewalls. Is it possible to use another distiller, perhaps http://dev.w3.org/2004/PythonLib-IH/dist/pyRdfa.tar.gz using Jython?
