ROO 1.1.3, I cannot get the JSON results

I did as what the doc said, defined all of my entities, and executed

Code:

---

controller all

---

, and then, I realize I need JSON result, so I executed

Code:

---

json all

---

, and executed command by maven (I chose the Google Appengine Datastore as my DB)

Code:

---

mvn gae:run

---

when I run

Code:

---

curl -i -H "Accept: application/json" http://localhost:8080/petclinic/owners

---

, I still get the html response, not JSON.

I reviewed the source, it did generate the *Controller_Roo_Controller_Json.aj files. And I rebuilt the web app, but I still cannot get the JSON response, but HTML response. What did I wrong? Did I miss some step? It cannot get the correct JSON response if I use GAE?

I regenerated the source by run the log.roo script, and it works well now.

I have no idea why it works well now, maybe I modified the source mannually before, but the roo shell was running and it updated the source everytime when I modified the java file. It must be something hidden bug hard to be reproduced.

Anyway, regenerate the source is not so painful, thank roo a lot.:p
