I'm looking at the example StockWatcher.java from GWT modified to use JSON 
and call a Web2py server app.

In the client app I'm 
using: http://127.0.0.1:8000/init/default/stockPrices.json?q=ABC
note the ".json" extension.

In my default.py in Web2py I have:
def stockPrices():
    sym = request.vars['q']
    rows = db(db.stock_price).select()
    prices = rows.find(lambda row: row.symbol in sym).as_list()
    return json.dumps(prices)

Is there an approach in Web2py I can use that I don't need to call 
json.dumps() when returning "prices" ? What are others doing?
