[Geotools-gt2-users] "Transforming" WFS

[Swan J. <Jer...@no...>]

(Appoligies to those who I've already inadvertantly spammed with the
following on WFS-dev):

I'm seeking to implement a "transforming WFS adaptor", i.e. a service
that sits between an external WFS client and server and allows custom
transformations to be performed on the geometry (the specific
transformations to be determined polymorphically).

Internally, there are 3 adaptor components: the client (which connects
to the external WFS server), the server (which connects to the external
WFS client) and the transformer (which polymorphically transforms client
output to server input).

While I've achieved this using a weakly-typed API (i.e. XML as String)
together with XSLT, it would clearly be preferable (from an adaptor
developer's perspective) if the API had the explicit representation of
features as Java objects that GeoTools offers.

Any tactical advice on how this could best be achieved using existing
GeoTools components (perhaps taking the WFSClient example from
org.geotools.demo.example as a base?) would be greatly appreciated.

Regards,

Jerry.
