Hi,

I had experienced an error message when tried to upload an rdf file, any clue ?

Some logs on fisuki container (I renamed /fuseki volume to /database) :

BTW, if I add a 'COPY inist.ttl $FUSEKI_BASE/configuration/inist.ttl' command to the Dockerfile in order to configure a Dataset on startup of Fuseki, it seems this file 'inist.ttl' is somehow not copied (or just deleted/overwritten). I had to add a 'cp "/inist.ttl" "$FUSEKI_BASE/configuration"' command to the 'docker-entrypoint.sh' file to make the Dataset appear on the jena-fuseki admin. interface !!
What am I missing ?

And here some other logs for docker command :

docker run --rm --name jena-fuseki -p 3030:3030 -e ADMIN_PASSWORD=123pw123 -e JVM_ARGS=-Xmx2g -v $(pwd)/fuseki-data:/fuseki jena-fuseki

When testing directly (without rebuilding image) with your image stain/jena-fuseki => gives this on Dataset creation : 'Not Found' !

On dataset creation, we get this in browser console about http request ! :

Thanks for help

Thanks for your report!

What is the content of your inist.ttl? It seems to make references to /database/ - how do you overridde the FUSEKI_BASE in your Dockerfile? This is also used by the entrypoint to set the password.

Do you have the content of your .rdf file publicly available? Are you sure it's RDF/XML format?

I am running with just docker run -p 3030:3030 stain/jena-fuseki and am able to make db1 as In Memory and db2 as Persistent. I tested uploading a .rdf file which parsed well (even if it has broken namespaces! :-)

Note when you are testing different images locally you should do a Ctrl-Shift-R reload to make sure the Fuseki web UI is not confused.

Hi and thanks for your feedback !

jena-fuseki without building it:

I am running with just docker run -p 3030:3030 stain/jena-fuseki and am able to make db1 as In Memory and db2 as Persistent.

The same here. Actually, it works well on my peronnal PC (non Professionnal). But it seems to work weird on my Professionnal PC (Ubuntu 16.04 LTS). Maybe something to do with POST requests (from UI to Jena API) bloqued somehow... ?

jena-fuseki with building it (I tried to adapt our old version jena-fuseki's v230 Dockerfile to yours v340, by adding the .ttl file config / Proxy settings...etc):

how do you overridde the FUSEKI_BASE in your Dockerfile?

Simply like that (/fueki becomes /database):

# Config and data
VOLUME /database
ENV FUSEKI_BASE /database

Do you have the content of your .rdf file publicly available? Are you sure it's RDF/XML format?

An internal rdf file, so not publically, but it already worked for sure on v230. Maybe v340 is more strict on parsing ?

What is the content of your inist.ttl?

Indeed, I removed all containers/images/volumes/binds before.

Well, it's all right now.
Maybe something weird with system/net buggy...

Thanks.
