Hi Carlos, The GeoTools library tends to be a bit more focused on the science side of things, so the StyledMapPane fell by the wayside. JMapPane is mostly intended for demos and to show you how to start making your client application.
When you add your shapefile you can provide a CoordinateReferneceSystem object if one was not already available using this method: - http://javadoc.geotools.fr/2.3/org/geotools/data/shapefile/ShapefileDataStore.html#forceSchemaCRS(org.opengis.referencing.crs.CoordinateReferenceSystem) Cheers, Jody > > Hello, My name is Carlos Ruiz, I´m from Colombia.
