Re: How to forward external-ip-facing requests from ApacheHTTPServer to Tomcat?
Hi, Thank you for the suggestion :) I will give it a shot but I am really too deep into my setup to be doing any big changes or something new! So while I try to google and learn more about setting up mod_proxy, I would really appreciate if someone can tell me: How do I go about configuring apache to forward the outside-facing-ip requests to Tomcat through JK connector? This should be something pretty standard for anyone who has ever moved Tomcat from a local testing env. (localhost) to a production env. (real ip) ...right?

Filip Hello Everyone, I have successfully configured Apache to forward requests to my Tomcat instance. But it does so...only for requests whose IP resolves to 127.0.0.1 If I try to access a page through apache server (that's actually on tomcat) with the outside-facing-ip of my computer it fails. For example: 1) URL: http://12.34.56.78:666/blah/serveMe.html;FAILS with a 404 (apache does not forward properly) 2) URL: http://12.34.56.78:8080/blah/serveMe.html; SUCCEEDS (tomcat seems to be ok when it gets the request directly, so it has to be a forwarding failure by apache in the previous case) 3) URL: http://my.domain.com:666/blah/serveMe.html; SUCCEEDS (I have my.domain.com mapped to 127.0.0.1 in my windows' hosts file) 4) URL: http://localhost:666/blah/serveMe.html;SUCCEEDS I think this happens because the 1st request (the one with the outside facing ip) is not forwarded to Tomcat by apache. a) The apache error logs show that Apache is trying to look for the page in the wrong place b) The access logs ofcourse show a 404 because it can't find the page to serve Now, I have read a few threads and been on a few forums and apparently my worker.properties file is supposed to be as simple as this: worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=my.domain.com worker.ajp13.type=ajp13 --- I also tried putting my outside-facing-ip and localhost as values for worker.ajp13.host but it didn't seem to make any difference at all. In that case I must ask all of you: Question 1: How do I go about configuring apache to forward the outside-facing-ip requests to Tomcat? If it is not done in workers.properties...then where is it handled? Question 2: Or am I wrong and it is actually handled by workers.properties? Even then, how? Thanks in advance to all those who answer and all those who take the time to read this. Cheers, - Pulkit - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to forward external-ip-facing requests from ApacheHTTPServer to Tomcat?
Hi Daniel, Firstly, Thank you for your response. Secondly, I must confess that I failed to grasp some of it due to my ignorance of Unix. I understood the overall idea but found myself scared/hesitant in implementing it as I'm using Win Server 2003. I'm a bit perplexed by the contents you said I could add to workers2.properties as I was not aware that fields were acceptable in such format. May be its the type of connector you are using or maybe its just my lack of experience/knowledge. I did find a soulution of ***sorts** which I would like to share with all of you so that you may comment/bash on its weaknesses/lamenesses thus helping me in finding a better one: *sigh* I just: a) Removed the 127.0.0.1my.server.com mapping from the hosts file. b) Added another Virtual Host to my server.xml file...resulting in something like this: !-- Define the default virtual host -- Host name=localhost ... Listener className=org.apache.jk.config.ApacheConfig modJk=c:/apps/apache/apache2/modules/mod_jk- apache-2.0.55.so / /Host !-- Define the hack virtual host for external-facing-ip requests Host name=my.server.com ... Listener className=org.apache.jk.config.ApacheConfig modJk=c:/apps/apache/apache2/modules/mod_jk- apache-2.0.55.so / /Host c) This happened to do the job, as now the file that Tomcat was auto-generating for use by Apache had some lines that accounted for the proper forwarding of external-facing-ip requests as well :) These were not there earlier and the file I speak of is tomcat_home\conf\auto\mod_jk.conf ) d) I still feel a bit jilted because my solution seems repetitive...there are 2 virtual hosts that are located in the exact same place and to top it off they have the same listeners inside them. They are identical in every aspect. I HAD tried entering Aliasmy.server.com/Alias under the localhost virtual-host but that did not seem to do the job... so I settled for having this repitition. Do let me know of your thoughts on this...

RE: How to forward external-ip-facing requests from ApacheHTTPServer to Tomcat?
Pulkit, I don't have any experience with WinServer (strictly a Linux man), but if it works... Also, it was my understanding (last time I checked) that no one's maintaining the old jk connector code - possibly because your method is now the recommended way? I don't know. Good luck!
