Re: Fuseki user-defined Web Services
Hi,
thanks for your comments.
Andy,
your link refers only to the embedded mode. How can I do something similar
for the standalone Fuseki server?
You wrote "JENA-1435 means it is possible to have "/dataset/MyService" and
provide the code for MyService without having to modify Fuseki source
code.". It seems to be sufficient for my use case but I need some guidance
how to implement it (how to register my own service as Fuseki service in
the standalone server mode).
Thanks,
Piotr

Hi Andy,
thanks for your answer.
I already started to experiment on hosting Fuseki using Glassfish server
and deploying those REST services on Glassfish and it seems this might be
the best way for us.
Thanks,

That is tricky - I can't think of a way to have the configuration
execute early enough.
The standalone and war full servers use webapp startup and web.xml where
are Fuseki basic is adding servlets to Jetty.
How much the full server and the UI did you want to use?
