Permission UniversalBrowserRead denied

Hi experts,

I am trying to access
http://localhost:8080/qc/SubjectCategoryListRetriever
from
http://localhost:8080/qc/index.html

and it throws an exception:  
Permission denied to call method XMLHttpRequest.open

so, i put the suggested fix:

try {
   netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
} catch (e) {
alert("Permission UniversalBrowserRead denied.");
}

alert("h1");
var transaction = YAHOO.util.Connect.asyncRequest('GET', "localhost:8080/qc/SubjectCategoryListRetriever", callback, null);
alert("h2");




but that just fails when trying to enable the permission.
can someone tell me what is going on?  

thanks
Daniel

Daniel,

This needs to be called from signed scripts. Check out this URL for details: http://www.mozilla.org/projects/security/components/signed-scripts.html

it turned out that i had to use relative paths instead of absolute paths, because it confuses 172.0.0.1 with localhost, as a crossdomain transaction
