I'm on ubuntu gutsy and I'm failing to get httpd to act as a proxy for tomcat.

I have a servlet running on tomcat at localhost:8082/testserv, which works if I address it that way.

I have symbolic linked ubuntu's files to load proxy_module and proxy_ajp_module (e.g. link mods-available/proxy.load and mods-available/proxy_ajp.load and mods-available/proxy.config to mods-enabled).

The proxy.config which I've modified some, looks like:

<IfModule mod_proxy.c>
ProxyRequests Off
<Proxy *>
AddDefaultCharset off
Order allow,deny
Allow from all
</Proxy>
ProxyVia On

ProxyPass /testserv http://localhost:8082/testserv
ProxyPassReverse /testserv http://localhost:8082/testserv
</IfModule>

I've restarted httpd, now when I access http://localhost/testserv, I get 403 forbidden and /var/log/apache2/error.log has:

[warn] proxy: No protocol handler was valid for the URL /testserv. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.

Do I need something other than mod_proxy and mod_proxy_ajp?

http://localhost:8082/testserv works.

Tomcat's logs have no errors in them.

I use mod_jk 1.2 for that. The docs at http://tomcat.apache.org/connectors-doc/ are pretty good, but if you have any specific questions please let me know.

My setup has mod_jk.so in Apache's module's directory and the following in the conf/extra/httpd-modjk.conf file referenced by httpd.conf:
In my conf/extra/httpd-vhosts.conf file use the following:
Lastly, for Tomcat I have the following in conf/jk2.properties:
Hope that helps...

Thanks, that seems to work.

hello frends...
what u mention files..that is not in my httpd directory? so please specify , m using fedora core6 and my httpd directory is
conf , conf.d, link to /var/log/httd,
link to /usr/lib/httpd/modules
link to /var/run
now no files like
conf/extra/httpd-modjk.conf
conf/extra/httpd-modjk.conf
conf/extra/httpd-vhosts.conf

plase specify this files or give me more information.
my httpd version is
Server version: Apache/2.2.6 (Unix)
Server built: Sep 18 2007 11:26:13

thank you..give me more information regarding this issue..

I created those files and added references to them in httpd.conf - they are not part of the standard install. You can add new files as long as you put something like this in httpd.conf:

and now no 8080 and 8009 port is not opened for this. so what should i do ?

hello,
i m using very 1st time tomcat. i know apache bt not tomcat.so please tell me begining.. which verison of tomcat should i use? and which version of connector for intregrate tomcat with apache?
and i want to open my jsp pages through 80 port so what should i do for that?
please help me. i m using fedora core 6 so please tell me begining.

Your JRE_HOME needs to be set to point to where ever your Java run time is installed.

I'm still using Tomcat 5.5. Although version 6 is out, I haven't had a chance to test it at work. I use mod_jk 1.2.26 as the connector.

If you're running Apache on port 80 and Tomcat on port 8080 and they're connected via mod_jk, then you will be accessing them via port 80. Apache will be configured to had those requests to Tomcat, so you don't need to change anything.

my confusion is between tomcat5 and tomcat5.5

i m using yum install tomcat so it download and install tomcat5 and you told me about tomcat5.5 that mean you r using apache-tomcat5.5 or another version? i that any difference between tomcat5 and apache-tomcat5.5? tomcat5 version is download and installed by yum updater and apache-tomcat5.5 is .bz format. so please tell me and i m using httpd2.2 also?

U r showing me apache-tomcat5.5 but which version i should download, cause it is available for core, deployer, embadded, administration web application, etc..please tell me.. i just wanna my jsp pages run on 80 port.

thank you for replying and help about above issue.

Tomcat is now part of the Apache software foundation so Tomcat and Apache-Tomcat are the same thing. Download the core version, the others should not be necessary.

If the Apache-Tomcat and Apache (httpd server) packages are available via yum and you're familiar with yum it may be easier to do it that way. Otherwise the earlier posts in this thread should have enough info.

thanks for everything. i just download core version and also download mod_jk connector what u define. have u any documentation for configuring this connector? how it configure? i used two types of method for same but still not working.. i cannot use 80 port for both html and jsp files.. So please have u any documentation for configure this connector, please send me...

thank you again and sorry for giving you little more trouble.




now i configure all the things..

thanx for giving me reply
Now i configured apache-tomcat 5.5 and httpd 2.2 and mod_jk_1.2.26. all configuration i did and first start tomcat and then httpd. now i can access localhost and localhost:8080 both..
and both are showing me apache and tomcat pages.but when i click localhost/jsp-examples then it show me error as below

now what should i do?

If you went through all of the steps in the posts above, there is a mod_jk.log file. Can you check that please and see if it has any more information? Also, what changes have you made - are your files the same as the ones above?

Thank you for everything. My tomcat and apache both works fine. Now i can
access via localhost/jsp-examples/ and it works fine. But when i open my hosted website www.mywebsite.com/jsp-examples, then it dosent works. so what should i do for that. www.mywebsite.com is already up and access anywhere from internet.

If you need any further information tell me, i give you more information abou that.

Thank you very much replying my request.

What error do you get when you use your hosted web site - is it a 404? When you installed Tomcat and mod_jk on that box did you use the same steps to set it up?
