The standalone and war full servers use webapp startup and web.xml where

How much the full server and the UI did you want to use?

Re: Fuseki user-defined Web Services

[Andy Seaborne]

A somewhat different form of customization.

JENA-1435 means it is possible to have "/dataset/MyService" and provide 
the code for MyService without having to modify Fuseki source code.


A JAX-RS module could use that to plug in.

It could not be used for the main Fuseki dispatch without significant 
replumbing of JAX-RS as Fuseki dispatch changes as datasets are added 
and deleted. Fuseki needs to respect the SPARQL protocols 9query, 
update, GSP).

Re: Fuseki user-defined Web Services

Is this just a Java thing, or does it mean that I can setup a REST service on 
Fuseki itself (maybe with some config file)?

Fuseki user-defined Web Services

[Piotr Nowara]

Hi,

is there any documentation describing the new Fuseki capability of handling
the user-defined services?

The 3.7.0 release info says: "JENA-1435: Provide extensibility of Fuseki
with new services. It is now possible to add custom services to a Fuseki
service, not just the services provided by the Fuseki distribution."

Does this mean I can create my own REST Web Service and host it using
Fuseki?

Thanks,
Piotr
