[Zoo-discuss] WPS

Thu Nov 28 22:17:51 PST 2013

Hi
I am getting the following error. *Unable to load the main.cfg file*
Since this is the first time am trying to load CGI Module I will list down
the steps I have followed.

 1. Downloaded the package and extracted it to *C:\inetpub\wwwroot\*.
 2. Edited the main.cfg present inside C:\inetpub\wwwroot\Dist\cgi-bin
folder. Replace the d:/ZOO_INSTALL_PATH and  d:\ZOO_INSTALL_PATH with
C:\inetpub\wwwroot\Dist
 3. Next I went to the IIS Manager. Under the Sites -> Default Web Site ->
Dist -> CGI-bin. I selected Handler Mappings from feature list and ensured
the Read Script and Execute permissions are checked.
 4. Then I added the Zoo_loader.cgi and Mapservr.cgi in ISAP and CGI
Restrictions
 5. Re stared the server
 6. And browse for the following :
http://localhost:8087/dist/cgi-bin/zoo_loader.cgi (I also modified my
main.cfg file for this address
*serverAddress=http://localhost:8087/dist/cgi-bin/zoo_loader.cgi
<http://localhost:8087/dist/cgi-bin/zoo_loader.cgi>*)
  7.  I am getting the following xml in the response.

<ows:ExceptionReport xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:xsi="

" version="1.1.0">

<ows:Exception exceptionCode="InternalError">
<ows:ExceptionText>Unable to load the main.cfg file.</ows:ExceptionText>
</ows:Exception>

</ows:ExceptionReport>

I am looking into it to see if this is an configuration issue at my end, or
if i have missed some thing that you can point out, it will be really
helpful.
Thank's
Anunay
