[Users] WFS not loading

Fri Mar 12 06:14:15 CET 2010

Hi list,

this post is regarding the earlier post called 'WFS not loading',

I'm going through the proxy setup, assuming the devil is in the detail.

I'm working with windows and Tomcat 6.

followed the example from Juan  to set the proxy -
http://www.mail-archive.com/users@openlayers.org/msg11290.html (he had
Tomcat 5) .

   1. I modified the file: "web.xml"

<servlet>
       <servlet-name>cgi</servlet-name>

 <servlet-class>org.apache.catalina.servlets.CGIServlet</servlet-class>
       <init-param>
         <param-name>debug</param-name>
         <param-value>0</param-value>
       </init-param>
       <init-param>
         <param-name>cgiPathPrefix</param-name>
         <param-value>WEB-INF/cgi</param-value>
       </init-param>
<init-param>
 <param-name>executable</param-name>
         <param-value>c:\python26\python.exe</param-value>
       </init-param>
<init-param>
         <param-name>passShellEnvironment</param-name>
         <param-value>true</param-value>
       </init-param>
        <load-on-startup>5</load-on-startup>
   </servlet>

   <!-- The mapping for the default servlet -->
   <servlet-mapping>
       <servlet-name>default</servlet-name>
       <url-pattern>/</url-pattern>
   </servlet-mapping>

   <!-- The mapping for the JSP servlet -->
   <servlet-mapping>
       <servlet-name>jsp</servlet-name>
       <url-pattern>*.jsp</url-pattern>
   </servlet-mapping>

   <servlet-mapping>
       <servlet-name>jsp</servlet-name>
       <url-pattern>*.jspx</url-pattern>
   </servlet-mapping>

   <!-- The mapping for the CGI Gateway servlet -->
   <servlet-mapping>
       <servlet-name>cgi</servlet-name>
       <url-pattern>/cgi-bin/*</url-pattern>
   </servlet-mapping>

2. I Did not rename the servlets-cgi.renametojar since in Tomcat 6 it is not
necessary.

3. copied the proxy.cgi from the openlayers website
to: C:\apache-tomcat-6.0.13\webapps\ROOT\FAFNR\WEB-INF\cgi\proxy.cgi

4a. in the proxy file I included my machine:  allowedHosts =
['localhost:8081', 'localhost']
4b. changed #!/usr/bin/env python to #C:/Python25/python.exe (I read
somewhere that's correct for windows user)!

5. in my map file I set the proxy: OpenLayers.ProxyHost =
"WEB-INF/cgi/proxy.cgi?url=";

Here I'm a little confused: shouldn't be the location point to
"cgi-bin/proxy.cgi?url="; because of the setting in the web.xml file?

6. included in the client folder the context.xml
file: C:\apache-tomcat-6.0.13\webapps\ROOT\META-INF\context.xml (privileged
is set to: "true")

7.- Restarted Tomcat.

Now, the WFS doesn't load.

*In Firebug:*

The Firebug response to the proxy call is the content of the proxy.cgi !!

as well as an error regarding python

not well-formed
#C:/Python25/python.exe

where did I miss something? is it the location of the proxy.cgi or is the
issue related to python.

Regards, Philipp
