Fuseki - problem with starting fuseki server (connection timed out)
Hi,
I'm having problem with starting fuseki server. I have a config file in
which I have declared my service and when I run command:
fuseki-server --config=config.ttl
the following log writes in console:
12:30:32 INFO Config :: Configuration file: config.ttl
12:30:32 INFO Config :: Service: :service3
12:30:32 INFO Config :: name = MODEL
12:30:32 INFO Config :: query = /MODEL/query
12:30:32 INFO Config :: graphStore(RW) = /MODEL/data
12:30:32 INFO Config :: graphStore(R) = /MODEL/get
and then I get:

I'm suspecting that the url for
PREFIX ja: <http://jena.hpl.hp.com/2005/11/Assembler#>
is not up... or maybe some other jena.hpl.hp prefix. Can anyone confirm
that?
because I used the same config file few days back and everythng was working
normal...
also, when I run fuseki with "fuseki-server --update --mem /ds" command, it
started successfully.
thank you for your answers!

Hi,
yes I'm using a bit older version of fuseki, I'll go and update on the
latest one.
also, you were right about that <> ja:imports d2rq: . I changed that so it
doesn't do import and it works fine now.
Thank you so much for the help!
Regards!

It's not that - using a prefix does not cause anything to read the URL.
[[
<> ja:imports d2rq: .
]]
You are asking the system to import the contents of the URL dr2rq: which is
<http://www.wiwiss.fu-berlin.de/suhl/bizer/D2RQ/0.1#>
This read is timing out - the remote server is not working whereas it
was last time.
(I don't know why you need to import that graph.)
