[OpenLayers-Users] CGI and Tomcat

[Juan Arévalo]

Hi!

I have finally managed to display my WFS example in the map! It is not so
obvious to set up the proxy host in Tomcat! I would like to share with you
all the steps  I followed, in case that someone need it:

1.- I modified the file: "web.xml" C:\Archivos de programa\Apache Software
Foundation\Tomcat 5.5\conf\web.xml. I uncomented the following lines of
code: 

    <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> 
        <load-on-startup>5</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
          <servlet-name>cgi</servlet-name> 
          <url-pattern>/cgi-bin/*</url-pattern> 
    </servlet-mapping> 

You have also to add this piece of code:

      <param-name>executable</param-name>
        <param-value>c:\python25\python.exe</param-value> 
       </init-param>

<init-param>
<param-name>passShellEnvironment</param-name>
<param-value>true</param-value>
</init-param>


2.- I renamed the file servlets-cgi.renametojar to servlets-cgi.jar under
the folder: C:\Archivos de programa\Apache Software Foundation\Tomcat
5.5\server\lib 

3.- I downloaded the "proxy.cgi" file from Openlayers:
http://trac.openlayers.org/browser/trunk/openlayers/examples/proxy.cgi and
copy the file in a folder called "cgi-bin" that I created under my
directory: "C:\Archivos de programa\Apache Software Foundation\Tomcat
5.5\webapps\client\WEB-INF\cgi\proxy.cgi" 

4.- In the proxy.cgi file I included my machine in the allowed hosts: 

allowedHosts = ['demo.mapfish.org', 'localhost:5000', 'localhost',
'127.0.0.1'] 

5.- I included this piece of code in my map: 

OpenLayers.ProxyHost = "/client/cgi-bin/proxy.cgi?url=";
6.- I also included in our client folder the context.xml file:

C:\Archivos de programa\Apache Software Foundation\Tomcat
5.5\webapps\client\META-INF\context.xml

Make sure that the privileged is set to: "true":

<Context privileged="true" antiResourceLocking="false"
antiJARLocking="false" />

7.- Restart Tomcat.
