I have just opened this thread to get some feedback about the debugging environment you are using. From some of the WRT presentations, the following approaches are suggested:

- Firefox
Javascript debugger plug-in
Implement S60 Web widget's specific object stubs
- On s60 emulator
use alert method
send log data to server
enable java/ecma script error from the browser settings

I tried to use the first approach in my project. As I am using AJAX requests, the following entry explained how to set up the debug environment
However, I have not been successfully and every time I send request and 401 HTTP request is gotten. Any idea?

You could also add any suggestions for debugging.
