Hi there, 

 

I am sending an issue that I could see in many mail lists, but I failed
to find a concrete solution.

 

 

I download the uk-1to250k raster files from ordnance survey. (1:250 000
Scale Colour Raster
https://www.ordnancesurvey.co.uk/opendatadownload/products.html) 

 

 

I Have my geoserver running on tomcat on win 7 machine. (I also have the
same error with my linux box).

 

 

I have my geotiffs (.tif files) together with .tfw files. (56 of each)

 

I included an .prj for each file (I read it on many mailing list and
forums that I should have the projection type file included)  this is
(EPGS:27700) (add 56 .prj)

 

 

Copy files on the data/os   ( path from tomcat webapps:
geoserver\data\data\os) I also have tried from (coverages/os)

 

I name the ds name : os250k

 

url= file:data/os 

 

 

I get this error

 

Could not list layers for this store, an error occurred retrieving them:
Unable to acquire a reader for this coverage with format: ImageMosaic

 

 

The log throws this error, here is a short version
