I am trying to add resources consisting of a shapefile (archsites.shp +
accessory files), a mapping file and a schema to the app-schema
src/test/resources/test-data directory in order to run unit tests using
shapefile-based datastores. I tested the mapping file and schema in
geoserver (built from trunk) and it seems to work fine, but when I try a
unit test in geotools, I get on the console:
Sep 22, 2010 4:43:19 PM org.geotools.factory.FactoryRegistry scanForPlugins
CONFIG: Factory implementations for category DataAccessFactory:
org.geotools.data.complex.DataAccessIntegrationTest$InputDataAccessFactory

org.geotools.data.complex.config.AppSchemaDataAccessConfigurator
acquireSourceDatastores
SEVERE: Cannot find a DataAccess for parameters {create spatial
index=true, memory mapped buffer=false,
url=file:src\test\resources\test-data\aecoreco\data\shapes\archsites.shp,
charset=ISO-8859-1}
with a trace of:
org.geotools.data.DataSourceException: Cannot find a DataAccess for

So it looks like I need to register a DataStoreFactory or
DataStoreFactorySpi for shapefiles in some META-INF file somehow. I
scanned the geotools manuals and lists looking for this but didn't seem
to find anything that I could recognise as relevant. Could someone point
me in the right direction? Thanks, Tara
