Hmmm... two things here: - the epsg-extensions module is there to allow you to add/override definitions, it's file based, and that's what we use in GeoServer for adding/overriding wkt definitions. You can use that as well - epsg-hsql need to write on the file system has been a source of troubles indeed, it would be better if we could use something that can read definitions out of the classpath directly. As far as I know H2 does support reading from databases in uncompressed zip files, and I believe JavaDB does too. My preference is with H2, and I'll probably propose soon enough a version running out of a zip file. I did provide a H2 version running out of the file system over 2 years ago, but it was not picked up, this time I'll try to do it out of a zip file: http://jira.codehaus.org/browse/GEOT-1430 Once we have that H2 + zip file I believe there won't be any more reason to work off the epsg-wkt file... or I'm still missing something? (I mean, H2 + zip in classpath is not really perceived as a database, doesn't it?)
