Thank you for the response. I have been using
urllib2.urlopen("http://www.openlayers.org";), so I can rule out the
url being incorrect. Since my original question I can add the
following:
1. I am not using a proxy to connect to the internet
2. I added these lines to the script:
...
proxy_support = urllib2.ProxyHandler({})
opener = urllib2.build_opener(proxy_support)
urllib2.install_opener(opener)
...
I believe this tells python not to look for a proxy server.
3. I have added http://www.openlayers.org and its ip to my windows
hosts file
4. socket.gethostbyname produces the same 11001 error as
urllib2.urlopen
You are spot-on suggesting a dns issue. It seems like python
cannot resolve hostnames when it is running in Tomcat 6. Here is
my Tomcat cgi config from 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:/Program
Files/Python25/python.exe</param-value>
</init-param>
<init-param>
<param-name>passShellEnviroment</param-name>
<param-value>true</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>
The hostnames consistently resolve in Apache Server with the same
script, so I don't think my dns config is wrong. I don't have a
local firewall, but could my network firewall be blocking python
from takin care of business? Can anyone share their experience or
a link on running python in Tomcat?
thanks again,
josh
