Re: Re: [Geotools-gt2-users] Overriding Feature IDs For PostGisDataStore ?

[Satyanarayana Murty Pindiproli]

  Hi Chris ,
 
  Based on your Idea I have started Impelementing My own FID Mapper Interface.However i find that I dont have any class by Name of JDBC1DataStore.I have a Class Named JDBCDataStore.
I am using 2.1.RC1 version of geotools.
Though i am sure this would work i wanted to know if there are Differences between these two classes which i may have to look into.

Please update me on any information that you have about this guys .
JDBC1DataStore and JDBCDataStore.


Thanks &
Regards.

Satya.
