Override web.http.JsonRequest for custom error handling v7.0

Question

Hello:
How can I implement my own custom error handling?  I need to remove the traceback when user is not in debug mode and instead display a more end-user friendly msg, in spanish.
I can't locate the web.main method to inherit. I tried inheriting  web.http. JsonRequest  dispatch() method but did not work.
Thanks
Mayte

Hi Mayte
Could you post what you tried with JsonRequest class to try it? normally this get solved by doing a monkey patch on addons/web/http.py
Like:
from openerp.addons.web import session,http
class JsonRequest(http.WebRequest):
def dispatch(self, method):
....my changes to error response here...
#monkey patching
http. JsonRequest =  JsonRequest

Hi Axel:
As you say, I did it by doing a patch directly on web/http.py, but sinces modifying core addons is not a recommended practice I want to inherit in my own addon.
I tried:
Created addons\my_addon\httpy.py as follows:
from web import session
from web.http import WebRequest
from web.http import JsonRequest
class JsonRequest(WebRequest):
def dispatch(self, method):
....my changes to error response here...  I added httpy.py to my init.py and even tryed adding dependance to web on my __opene
