Re: [Geotools-gt2-users] Simple map with points

[Sami D. <sk...@fr...>]

Hi,

sorry to bother you once again, but I can't get this to run...

- All FeatureTypeFactory methods are deprecated. Looks like we are suppos=
ed to
use FeatureTypeBuilder, but javadoc says that a builder instance is
instanciated thanks to a FeatureTypeFactory.newInstance() method, which i=
s
deprecated...
- Even inside deprecated methods, I don't see any CoordinateReferenceSyst=
em
parameter
- What is the string that I am supposed to pass to
MemoryDataStore.getFeatureSource(String) ?

Thanks a lot,
Sami Dalouche
