Hi,
MySQLDataStore currently does not supports CRS , cause of which when one
tries to render mysql geometries using StreamingRendererer (2.4-M1)
the following exception is thrown
Mar 31, 2007 4:29:14 PM
org.geotools.renderer.lite.StreamingRendererprocessSymbolizers
WARNING: null

A possible fix is to modify the buildAttributeType to take in account the
CRS of the table or geometry .Example modification of Mulitpolygon
return AttributeTypeFactory.newAttributeType(rs
.getString(COLUMN_NAME), MultiPolygon.class);
to
return AttributeTypeFactory.newAttributeType(
rs.getString(COLUMN_NAME),Geometry.class, false, 0, null,
DefaultGeographicCRS.WGS84);

Thanks and Warm Regards
