How to enable CORS on Fuseki2

[Jeffrey Witt <je...@gmail.com>]

Hi, 
I just updated to Fuseki2 from Fuseki1. With Fuseki1 I was enjoying the
enabled CORS support, especially important for javascript only, single page
apps. 

But, as I¹ve gleaned from this post:
https://issues.apache.org/jira/browse/JENA-652 CORS is not enabled by
default for Fueski2. I wonder if it is now possible to enable CORS for
Fueski2. If so could someone guide me through the enabling process.

(I have little to no experience with writing in Java, so I might need
detailed instructions).

Thanks in advance.

Hi there,

You'r right - CORS is not enabled in Fuseki2. It would eb re

if you are deploying Fuseki2 with the standalone server jar 
(fuseki-server.jar), not the WAR file, you can follow the instructions 
for Jetty [1] to enable it (no Java required, editing web.xml is required).

The web.xml file is in webapp/WEB-INF/web.xml of what usually FUSEKI_HOME

The war file can also be done - it needs unpacking, changing web.xml and 
repacking.

-----------
There's machinery in Fuseki2 for this (and a request routing problem - 
now being fixed).

What would help me is someone with experience to advise what the headers 
should be for the various options and especially whether one choice of 
settings is good for everyone or whether this needs configuration in 
some way.  Even if the latter, what is the best out-of-the-box settings?

If it is one universal set of settings, is better (safe) to do in 
Fuseki2 or, for example when running in Tomcat, should Tomcat do it?
