Here is the problem Justin, MemoryDataStore implements sorting in GeoTools 2.2 - since this is against our own GeoTools interface SortBy interface; we need to do the deprecation dance as we move to GeoAPI. Aside: SortBy2 is our convention to allow extensions beyond the OGC specifications, the specification only allows a propertyName as far as I understand it - hense SortBy2.
I am not familiar with JDBCDataStore and its friend SQLBuilder, but your suggestion sounds good. Cheers, Jody > Hi all, > > Starting to tackle sorting as part of wfs 1.1.
