Hi,
I'm playing around with Geoserver WPS features. I've implemented a small WPS process but I'm stuck trying to customize the WPS DescribeProcess response. Here is what I'm trying to do : I wanna do something almost like gs:Reproject but I want to be able to support only a few input and output CRS. Therefore I'd like the DescribeProcess to list the supported CRS for my WPS process.
I've tried some dirty tricks (like implementing an enum for the CRS type => It works (nice surprise) but of course ":" (colon) is not accepted by Java in an enum key).
Do you have any ideas/clues on how to achieve this ?
10x in advance
Manu

Eh, are you trying to do the INSPIRE compliant reproject? 
Right now there is no way to do what you want, we’d need to expand
Parameter back in GeoTools to provide a domain of possible values,
then change the annotation system to provide that list, and finally
alter the DescribeProcess to use it

He he spot on 
Ok ... Just as I thought I'll have a closer look at Geotools and Geoserver WPS core to see what I can do.
Cheers
