debugging and running a widget

[ferranhalden]

Hi,

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
Firebug
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
http://blogs.forum.nokia.com/blog/ja...illa.com-en-us
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.

Cheers

Hi,

if you're facing issue with the AJAX requests handling in firefox.

option-1:
Get GreaseMonkey + XMLHttpRequest Bypass script hack

If this doesn't works for try next option

option-2:

Setp-1:
---------------------------------------------+
Add this line of Javascript code before calling each XMLHTTPREQUEST.open function
netscape.security.PrivilegeManager.enablePrivilege(”UniversalBrowserRead”);

// create XmlHttpRequest Object
var xmlhttp = new XMLHttpRequest();

// Enable Universal Browser Read
try{ netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead"); }
catch(e){ alert(e); }

// before each
xmlhttp.open(METHOD, URL);

Step-2 {Optional for FF2 / Mandatory for FF3}
---------------------------------------------+
- Open Firefox browser and navigate url > "about:config"
- Search this property by using the filter "signed.applets.codebase_principal_support"
- and set the Boolean value to "true"

Comment : A codebase principal is a principal derived from the origin of the script rather than
from verifying a digital signature of a certificate. Since codebase principals offer weaker security,
they are disabled by default in Mozilla. More info: http://www.mozilla.org/projects/secu...d-scripts.html

Step-3 {Optional }
------------------+
- Open Firefox browser and navigate url > "about:config"
- Search this property by using the filet "security.fileuri.strict_origin_policy"
- and set the Boolean value to "false"

Comment : allowed XMLHttp to do it’s thing from a file:///

Hope this helps you.

Thanks for your suggestion.

I have setup the following environment:

- firefox 2.0.0.17
- firebug 1.0.5
- greasemonkey 0.7.20070607.0
- XMlhttprequest - bypass security script

I have followed your steps until point 2-b, because I don't see the last property you mentioned "signed.applets.codebase_principal_support".

I have not been successful. Any time I sent a request, I am getting an HTTP 401 as response. However, I can not see in the NET panel of firebug that those requests have been performed.

Any idea?
