[Geoserver-users] Unknown namespace WFS error in Firefox / IE

[ChrisFleet]

Hello Folks,

We have been using GeoServer in two installations (versions 1.7.2 and 1.8.0)
for six years and been very happy with it. We use it to display bounding
boxes of historical maps and allow selection of these through WFS queries.

In the last week there have been changes made to the servers, as well as an
update to the GeoServers from a backup, and - returning from a holiday to
discover this - these seem to have now caused a fatal error for our WFS
requests.

All our layers are in a single Workspace 'nls' and we access them through a
WFS request along these lines:

http://geoserver.nls.uk/geodata/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=nls:catalog_1inch_1st_3rd&outputFormat=text/javascript&format_options=callback:loadFeatures&srsname=EPSG:3857&cql_filter=INTERSECTS(the_geom,POINT(311912.45037301356%20665758.4406516276))

This sometimes is returning a correct JSON response in Chrome, but not in
Firefox, IE or Edge.

Also, our GeoServer logifiles are now giving a regular error:

ERROR [geoserver.ows] - org.geoserver.wfs.WFSException: Unknown namespace
[nls]

A demo application with a few layers can be viewed at:
http://geo.nls.uk/maps/dev/NLSFindByPlaceOL3/index.html
<http://geo.nls.uk/maps/dev/NLSFindByPlaceOL3/index.html>

This displays the bounding boxes correctly from GWC but when you click on a
coloured rectangle, it only returns the details correctly in the right-hand
results column in Chrome.

The code behind this (with the relevant Javascript in find.js) can be viewed
at: https://github.com/NationalLibraryOfScotland/NLSFindByPlaceOL3
<https://github.com/NationalLibraryOfScotland/NLSFindByPlaceOL3>

This is probably / hopefully something very simple, but we seem to have
tried everything. It may not be a GeoServer error but something at
network/server level. Very grateful for any ideas.

Thanks,

Chris

Just as a follow-up message to this, I have just discovered that if I am
logged into GeoServer, the WFS requests work in that browser fine - so it
must be a security setting.

I am still searching for the solution, so very grateful for any ideas on
this more specific problem.

Thanks,

Chris

Hi Chris,
from here on Linux that call returns proper responses for both Chrome 59
and Firefox 54.
The application also works fine in both.
Telling what's wrong in such a old GeoServer is... well... going to be
really hard, it may well
be that nobody around remembers issues of those versions :-)

Cheers
Andrea

Many thanks for your reply, Andrea.

Yes, we are planning to upgrade.

Just to say, in case my earlier message didn't get through, we solved this
by changing settings under Security > Data. Somehow our main nls workspace
did not have the ROLE_ANONYMOUS set and when we did this, all worked fine.
This setting somehow got overwritten without us realising, so we looked
initially in the wrong place for the solution.

Very grateful to you for looking into this.

Chris

A final follow-up, just in case useful for others.

nls workspace did not have the ROLE_ANONYMOUS set and when we did this, all
