I have created a php page that makes use of Google Javascript APIs. I am trying to use Ajax to populate the info windows of the markers dynamically, but get a permission denied error on the xdr.open line. I have checked the other posts relating to similar errors, and tried different changes, but still the same error.

Is
GroovyCaller.phpreturning the http headerAccess-Control-Allow-Origin? From http://msdn.microsoft.com/en-us/library/cc288060(v=vs.85).aspx:Your server must know about your client to accept a cross domain connection. You can start with
Access-Control-Allow-Origin: *to get it working, and then narrow it down.
