Fuseki OWL Reasoner Configuration
I am new to Apache Jena and Fuseki.
I was able to run the docker version of Fuskei (jena-fuseki-docker-3.17.0 distribution) successfully. However, I am not that successful with being able to run Fuskei with any reasoner. Appreciate any help you can
In order to narrow down the problem, I am now running Fuseki in Standalone mode in Windows 10
> fuseki-server --tdb2 --loc data -v --update /ds
I modified the Template file (config-tdb2-dir) at ./run/templates/config-tdb2-dir

Thank You Andy ad Sorin
I was using Fuseki full but was relying on a template to get picked-up based on the cmd line options --tdb2 --loc data . Using explicit --config worked.
I assumed that the template file will get automatically applied with the right DIR and dataset NAME.
Thank You
Gowrisankar

The docker version is Fuseki/main (no UI, and it does not use the
template files) but the log output:
>
file:///C:/developer/graph/bin/apache-jena-fuseki-3.17.0/webapp/,UNAVAILABLE}
that seems to be Fuseki full - the webapp (war file or prepackaged with
Jetty as the webapp server. That does use templates built into the binary.
Not sure what's happening here. The way to run with a custom
configuration file is specifiy it on the command line ...

There is an example configuration file:
https://github.com/apache/jena/blob/master/jena-fuseki2/examples/config-inference-2.ttl
fuseki-server --conf MyInf.ttl
Andy
I did try your modified template file in Fuseki full (not docker) and it
seemed to worked for me. --conf is the better way to specific a
configuration.
