[geotk] Implementing a WPS

[Adrien ANDRE]

Hi all,

I have a remote sensing tile set.
I built an algorithm that returns a list of underlying tiles given a 
feature collection.

Using Netbeans i'd like to implement this as WPS method.

Could you tell me what the main steps are, to achieve this?

I actually previouly implemented a simple web service that works well:
getUnderlyingTile(double longitude, double latitude) : String tileID

But i'm not at ease with complex types, and dont know how i could use 
these to return geographic features.
Even if i guess the response contains GML.

Regards,

Adrien
