Good thinking. GeoTools is wired up at runtime using Java Service Provider Interface (SPI) plugin system. This is a very simple system that uses text files located in META-INF/services to list what implementations are available in each jar.
To try it yourself consider this tutorial: http://docs.geotools.org/latest/userguide/tutorial/function.html I can find the EPSGCRSAuthorityFactory being hooked up correctly in the epsg-wkt jar here <https://github.com/geotools/geotools/blob/master/modules/plugin/epsg-wkt/src/main/resources/META-INF/services/org.opengis.referencing.crs.CRSAuthorityFactory> . The other one "org.vfny.geoserver.crs.GeoserverOverridingWKTFactory" seems to come from geoserver? So perhaps this is a geoserver-devel question. -- Jody Garnett On 27 August 2015 at 01:11, Marcel <[email protected]> wrote: > Hello all, > > When running a jar-file on yarn I get the following error message: > > WARNING: Can't load a service for category "CRSAuthorityFactory".
