Re: SPARQL with UNION returning TDBTransactionException

Try using a service like Github Gist. Is it possible that only one of the legs of the query has results in it? Have you confirmed that _neither_ of the legs executed separately shows the problem? ajs6f > On Feb 28, 2017, at 4:51 AM, Andy Seaborne wrote: > > What people on the list receive is

Re: paging the query results

One option: Jena is now using Java 8, so you can use the Streams API to do this: https://stackoverflow.com/questions/29273705/how-to-paginate-a-list-of-objects-in-java-8 ResultSet is an Iterator, so you can convert it to a Stream. --- A. Soroka The University of Virginia Library > On Sep 16, 20

Fuseki (and the rest of Jena) now requires Java 8. That's the problem you have here. --- A. Soroka The University of Virginia Library On Aug 24, 2015, at 1:25 PM, Colin Maudry wrote: > Hello, > > I've been using Fuseki 2.0 for months on Ubuntu 14.04, and realized a > v2.3 was out. > > 1. I d

Re: Apache Maven

Apache Maven is the build management system used by Jena. You will find info here: https://maven.apache.org/ If you are just using Jena as a framework or toolkit you will probably not need Maven. If you intend to do actual development work on Jena, you will need to become familiar with Maven.

Re: EmbeddedFusekiServer in Fuseki 2

I don't know what you need an embedded server for, but if, by chance, it was for use supporting SPARQL endpoints in integration tests and you are using Maven, you can take a look here https://github.com/ocymum/trippi-sparql-update/blob/master/pom.xml for an example of some Maven-fu that uses th

Re: Fuseki over HTTPS?

Are you deploying Fuseki to your own servlet container (e.g. Tomcat or Jetty) or using the server included with Fuseki and is it Fuskei 1 or 2? If the former, you will need to supply configuration specific to that container. If the latter and it is Fuseki 1, there is a Stack Overflow answer for

There may be a better answer for this, but at the very least, you can serialize your triples/quads and use SPARQL Update to send them to your Fuseki instance. --- A. Soroka The University of Virginia Library On Aug 17, 2015, at 3:08 PM, Andy Doddington wrote: > > On 17 Aug 2015, at 19:50, An

Re: Support for a Graph.getName()?

Since this is essentially about debugging, would it suffice to require Graph implementations to provide something in toString() to uniquely identify themselves, or do you really require user-settable or -accessible labels? --- A. Soroka The University of Virginia Library On Aug 5, 2015, at 8:35

Re: Uploading file in fuseki

For the first case, you should be able to HTTP PUT your file directly to the appropriate URL, e.g. http://remoteserver.com:3030/ds/data. You could also go to http://remoteserver.com:3030 and use the forms made available there. --- A. Soroka The University of Virginia Library On Jul 24, 2015,
