Hi,
I'm trying to serve raster data hosted in a PostGIS 2.0 through
GeoSeser via the ImageMosaicJDBC plugin. I'm currently using geoserver
2.2-RC2 and gt-imagemosaic-jdbc-8.0.
I was able to publish my new layer and I can see into the
getCapabilities response of my WCS service. However I can't request it
through a GetCoverage request in both 1.0.0 or 1.1.0 supported
version.
Here is the current stack trace I'm getting:

I debugged the existing code and figure out that the problem is
occuring because the requestedEnvelope property of the
ImageMosaicJDBCReaderState instance is null and then it cannot be
read. This happens because the READ_GRIDGEOMETRY2D is not set into the
GeneralParameterValue array passed as argument of the
ImageMosaicJDBCReader.read method. This is happening because this
property is explicitly ignored into
org.geoserver.data.util.CoverageUtils when the GeneralParameterValue
array is created.
Please can you help me to figure out was is wrong with my current
setup. The equivalent GetMap request is working perfectly fine.
Thanks.
