You can stay with 3.1.0 for the moment (obviously, you'll eventually want to
upgrade to get all the other good things in 3.1.1 {grin}).
For 3.1.0, please look at:
https://jena.apache.org/documentation/query/service.html#controlling-service-requests
and especially at the last paragraph:
https://jena.apache.org/documentation/query/service.html#srvservicecontext
In that paragraph is explained the mechanism by which you can "override system
context settings on a per URI basis" (quoting from it). That's a way that you
supply a specific username/password combo (aka
srv:queryAuthUser/srv:queryAuthPwd combo) for a specific service at a specific
URL. As the notes there say, you can do this either on a per-query basis (by
passing in a Context, just as you surmised) or in the static ARQ context (which
would make your config available to all queries).
Does this help?
