Almacen de datos raster de POSTGIS.

[Juan Carlos Romero]

Tengo cargado en la mi base de datos PostGIS un Geotiff de 8BITS de profundidad de color. Supongo que la carga es correcta pues mediante un script php hago una consutla SQL a la base de datos y me muestra el TIF correctamente. Mi problema viene al cargarle en Geoserver. Al agregar un nuevo almacén de datos siempre obtengo el mismo error tras varias pruebas: Could not list layers for this store, an error occurred retrieving them: El argumento "value" no debe ser nulo.

He realizado la configuración siguiendo lo indicado en http://docs.geotools.org/latest/userguide/library/coverage/pgraster.html

He cargado el Geotif en la tabla 200504precipitacion.

He creado la tabla masterinterpolacion

CREATE TABLE public.masterinterpolacion

(

  name character varying(254) NOT NULL,

  tiletable character varying(254) NOT NULL,

  minx double precision,

  miny double precision,

  maxx double precision,

  maxy double precision,

  resx double precision,

  resy double precision,

  CONSTRAINT "masterInterpolacion_pkey" PRIMARY KEY (name , tiletable )

)

He insertado los valores name=recipitaciones y tiletable=200504precipitacion.

He creado los parámetros de conexión, guardados en la carpeta coverages

connect.pgraster.xml.inc

</config>

Y siempre obtengo el mismo error, el log de Geoser er aparentemente no muestra nada especial:
