[OpenLayers-Users] trouble adding local kml file to OL

Tue Apr 12 18:17:18 EDT 2011

Hi all,

I;m having some trouble adding a kml file to openlayers. The script is at
bottom, and i've followed this thread without solving the problem:
http://osgeo-org.1803224.n2.nabble.com/adding-KML-file-td6003583.html

note that
(a) i have apache running (but no proxy host configured- i tried to do it
but it broke my web server, i'm not an expert at troubleshooting it.
(b) webserver is back on - i use it for an application with php and postgis
(which i actually want to link to an OL application)
(c) i am new to OL

1. with both the html and kml file on the webserver,
- i get only the google map displayed, no kml file displayed
- no error message
- no kml file displayed

2. with the html on local folder and kml file on webserver
- i get only the google map displayed
- error message Access to URL denied" code" 1012

3. with both html and kml files in local folder
   - same response as 1 above
   - although i dont know if i shoulde be using url to point to the file in
this case

The code is below. Any help appreciated!!
Also, do i absolutely need proxy hosting or is there some way i can use my
existing webserver and working postgis as is?
Thanks,
Vishal
