Hi Peter,
It's weird that the ProjectionFactory isn't returning a set of
projection classes available, your properties look OK. The default
projection can be set in the openmap.properties file, by listing the
class of the default projection where you used to use the projection's
id name.
for instance:
openmap.Projection=com.bbn.openmap.proj.CADRG
But if the ProjectionFactory isn't being loaded properly, it'll return
a Mercator projection.
You can run with the -Ddebug.componentfactory flag to make sure the
different components are being created at startup.
