Ok. I did resolve it:
from geoserver.wps import process
#from geoscript.geom import Geometry
from StringIO import StringIO
@process(
title='Sample',
description='Sample',
inputs={'arg1': (int, 'first argument'),
'arg2': (int, 'second argument')},
outputs={'result': (str, 'The buffered geometry')}
)
def run(arg1, arg2):
#return "hello world";
return str(arg1+arg2);
I'll continue working on it. Thanks for the help.
