[Geotools-gt2-users] Map Viewer help

[Antonio Caccese]

Hi i wrote the post "Passing 2.0 to 2.1" but i haven't any response. I am working to a map viewer for my thesis at University of Salerno (Italy). I have finished to work with shapefile and i have created a fully functional viewer that offer some functions as add and remove layer, zoom in, zoom out, zoom to full extent, rotation of the map, drag the map, find a feature, identify a feature, and a query builder. All this functions are based on StyledMapPane. In particular, I wrote the class MyStyledMapPane that overwrite some method of the ZoomPane class. I’ve added it standard mouse listener to perform operation like dragging map or identifying a feature. The final version of my map viewer must load also raster format. Geotools 2.1 release is more powerful than release 2.0 about raster management and so I would pass from 2.0 to release 2.1. When I load the first shapefile in mapPane I obtain the following error message: 18-ott-2005 15.13.51 org.geotools.map.DefaultMapContext getLayerBounds GRAVE: Data source and map context coordinate system differ, yet it was not possible to get a projected bounds estimate... org.opengis.referencing.operation.OperationNotFoundException: Bursa wolf parameters required.     What’s the right configuration of coordinate system for the StyledMapPane?     Thanks in advance.
