Hi > Could you tell me how to modify Geoserver's source code?
No. But I would ask your boss why he wants to change the source code when there are easier options. regards Stefan > Date: Thu, 28 Oct 2010 11:15:18 +0200 > From: [email protected] > To: [email protected]; [email protected] > Subject: AW: [Geoserver-devel] How to change Geoserver's source code to > offset GIS data > > Hi > > > > your aim is not to change GeoServer's source code.
