Dear Ben, thanks for your reply. I built the uber-jar (lol..) with the eclipse-integrated function to export jar. I chose the options "Runnable Jar File" and "Extract required libraries into generated JAR". These options work perfectly well for some projects the JAR is used in, but not in every. The FileDataStoreFactorySpi is definitely there in the required folder, but it only contains the line "org.geotools.data.shapefile.ShapefileDataStoreFactory", is that correct? Nevertheless, this class exists. The (now extracted) classes of the gt-shapefile are there as well (org.geotools.data.shapefile.*, org.geotools.data.shapefile.dbf.*, org.geotools.data.shapefile.indexed.*, org.geotools.data.shapefile.indexed.attribute.*, org.geotools.data.shapefile.prj.*, org.geotools.data.shapefile.shp.*, org.geotools.data.shapefile.shp.xml.*). Just how Maven built these; in the pom.xml the gt-shapefile entry exists.
This seems to be weird... Like I said, it works fine in "my" project, but not in the "big one" we need it for. Nevertheless, thank you for your help.

How did you build your uber-jar? Did you concatenate all the /META-INF/services files? This is a Java SPI error that should never occur if you have the gt-shapefile jar on the classpath. It looks like something is trying to discover a provider for FileDataStoreFactorySpi; I think gt-shapefile provides the only (supported) implementation. Either you lack gt-shapefile or its /META-INF/services/org.geotools.data.FileDataStoreFactorySpi has been damaged/removed. If a JAR file contains files in /META-INF/services named for the long class name of an interface, they list list implementations of that interface that can be discovered dynamically at runtime. This is the Service Provider Interface (SPI): http://docs.oracle.com/javase/7/docs/technotes/guides/jar/jar.html#Service_Provider You can have multiple service providers on the classpath. They are searched in the order found. Kind regards, Ben. On 14/02/14 17:51, Oehler, Philipp wrote: > Dear Geotoolers, > > I’m using geotools in a big project.
