Hello everyone,
I´m new to geotools and I want to use the CRS.decode() method on the
server side of my GWT (Jetty Servlet Container) application. But I
always get an Exception. I included all the jars from the binarys
except the epsg ones, because I read about that (only extension and
hsql are included). I´m using geotools 2.7 M1, Eclipse Helios, Java
JDK 1.6.0_18 and Windows 7 32bit. It might be the case that Windows
prevents the hsql-epsg from writing its database to the harddisk, I id
not find any of the files. I do not know how to give geotools write
access if that´s whats causing the error...
I appreciate all comments and ideas.
Thank you and Best regards
Felix
