Hi Henrik, I presume you are following the instructions at:
https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtSesame2HttpRepository
<https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtSesame2HttpRepository>
When during the addtion of the repo is the error occurring ? I assume Virtuoso
is at least listed as an available repository and you have provide connection
details and if so please provide the details of the connection params passed ?
And it is at the point of added the Virtuoso repo that the error is occurring ?
If the RDF4J HTTP server is attempting to connect to Virtuoso then you can
enable tracing to the “virtuos.log” file using the trace_on() function as
detailed at:
http://docs.openlinksw.com/virtuoso/fn_trace_on/
<http://docs.openlinksw.com/virtuoso/fn_trace_on/>
Which should provide details of what is occurring in Virtuoso and hence
possible cause of the problem ...
Best Regards
Hugh Williams
