Hi,
I think it might have been more to do with the database tables again as I was
trying to use a custom schema rather than public.
I’ve now reconfigured my store to use the public schema and renamed my stores /
tables to be lower case names. This means the error has gone away but I still
have not been able to get GeoServer to create and populate a new layer.
On the plus side, my layers are now working again now but I’m unsure if that is
from the GWC or the GeoServer really; I think it is working though.
I’m still a little confused as to whether it tries to generate a schema per
layer or a table but that might just be due to the wording of an error message.
Thanks,
Paul

Subject: RE: [Geoserver-users] Image Mosaic failing to create reader again
Hi Andrea,
Thanks for the reply, is there a good place for me to start looking i.e. a part
of the source code which defines the process of setting up the table etc?
I don’t know why but I still can’t quite get my head round where the source
code for plugins is actually stored?
I’m still no help at all when it comes to development work as I still keep
meaning to come along to an event or code sprint of some sort to get my head
around the processes. Sorry about that, the kids are still very young and so
there is very little time outside of work to learn new scripting languages.
Cheers,
Paul

Hi Paul,
rasters failing to load do not report any error to GeoServer, just a null. This
is a 10+ years old design mistake that's expensive to fix today (idea, add a
flag to make them throw an exception, retrofit each and every one of them to do
so).
As Daniele suggested, currently the way is to switch to gt Dev logging and hunt
into the many messages (some of which are red herrings).
The mosaic is especially hard because during init it creates tables, config
files and the like, won't revert them on failure, and won't proceed further in
the next setup if it finds them... So you have to know what to look for and
delete manually.
I hope one day we can setup a code Sprint with a few devs, for a few days, to
actually start returning meaningful info out if failures.
Cheers
Andrea

Hi,
I’m struggling with the same image mosaic error I had a while ago but in a
different context.
I’m trying to create an image mosaic using a local PostGIS database (running on
localhost to the GeoServer) but I’m getting:
Could not list layers for this store, an error occurred retrieving them: Failed
to create reader from file:Raster/Test2 and hints Hints: EXECUTOR_SERVICE =

FORCE_AXIS_ORDER_HONORING = http STYLE_FACTORY = StyleFactoryImpl
FORCE_LONGITUDE_FIRST_AXIS_ORDER = true COMPARISON_TOLERANCE = 1.0E-8
GRID_COVERAGE_FACTORY = GridCoverageFactory TILE_ENCODING = null
The store I’m using to connect appears to work and I’ve even managed to create
the whole database using the GeoServer; all looks fine. However when I go to
create an image mosaic I get the error above and no table is created within the
schema.
My question is simple enough, does anyone know if the error is really caused by
issues connecting to the database or could it actually be caused by issues with
the location of the image directory?
The system was working but I was trying to rebuild it from scratch on a later
version of Windows Server (2016 I think) and the data directory is now on a
network drive. Despite the number of times I’ve looked at this error message I
still find it confusing to identify what the GeoServer is actually trying to
do, is it trying to read the files, write to the database, create a table or
index?
Alternatively are there preparedStatements missing on my version of PostGIS or
something like that?
As usual I would be really grateful for any hints but of course I know everyone
is very busy.
