Re: urlopen error (11001, 'getaddrinfo failed')
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-namecgi/servlet-name servlet-classorg.apache.catalina.servlets.CGIServlet/servlet- class init-param param-namedebug/param-name param-value0/param-value /init-param init-param param-namecgiPathPrefix/param-name param-valueWEB-INF/cgi/param-value /init-param init-param param-nameexecutable/param-name param-valueC:/Program Files/Python25/python.exe/param-value /init-param init-param param-namepassShellEnviroment/param-name param-valuetrue/param-value /init-param load-on-startup5/load-on-startup /servlet servlet-mapping servlet-namecgi/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 On Fri, 11 Sep 2009 08:54:20 -0500 Chris Withers ch...@simplistix.co.uk wrote: open...@hushmail.com wrote: fs = cgi.FieldStorage() url = fs.getvalue('url', http://www.openlayers.org;) try: insert a print url here... y = urllib2.urlopen(url) print y.read() This script produces the urlopen error (11001, 'getaddrinfo failed').

urlopen error (11001, 'getaddrinfo failed')
Hello Python User, I am using python in an openlayers application to access another server on my network via javascript. The proxy script works fine when the application runs in Apache HTTP Server, but I get a urlopen error (11001, 'getaddrinfo failed') error after moving the application to Tomcat. The tomcat cgi configuration tested fine with a hello world python script. I then boiled my proxy script down to the following: #!c:/Program Files/Python25/python.exe -u import urllib2 import cgi fs = cgi.FieldStorage() url = fs.getvalue('url', http://www.openlayers.org;) try: y = urllib2.urlopen(url) print y.read() except Exception, E: print Status: 500 Unexpected Error print Content-Type: text/plain print print url: , url print print Some unexpected error occurred. Error text was:, E This script produces the urlopen error (11001, 'getaddrinfo failed'). The openlayers homepage is expected. My environment is Tomcat 6, Apache 2, Win XP, and Python 2.5. I have my local firewall turned off. Proxy support is enabled, and working, in Apache 2.0 (I get the error with Apache Server stopped). I seem to be missing something to facilitate the communication between python, my network and tomcat. Any direction or solution is greatly appreciated.
