Thank you..this worked like a dream..

but applications seem to be accessible from tomcats port as well.. how can i block that.

i just want the applications to be accessed from apache(port).

btw both tomcat and apache are on same unix server.

2010-10-04T21:13:39.128-07:00

for me, its three part configurations,
1. apache, to load mod_jk.so, forward request to workers
2. tomcat, the worker connect to tomcat ajp1.3 connector port, so that tomcat would be notified of the forwarded request.
3. especially import, the worker port should be same as tomcat ajp1.3 connector port.

2010-04-06T13:40:47.801-07:00

Thanks for such a nice Blog. I install Apache httpd 2.2, tomcat 6.0. I installed apache as root user and tomcat as tomcat user. I downloaded tomcat-connectors-1.2.28-src. Now i m trying to configure it as a tomcat user, but unable to configure it. getting error " cp: cannot create regular file `/usr/local/apache2/modules/mod_jk.so': Permission denied
"
Is there any way to configure it as tomcat user or do i have to configure it as root.

Please advice.

Thanks
Manoj

Hi Grig,
Great post, after a little effort I managed to get it working with Tomcat on port 8080. I have another server running Tomcat on port 80 and can't figure out how to get the right port for the worker. After a netstat -anp, I am non-the-wiser, any ideas ?

2008-04-11T17:53:00.000-07:00

The above examples will serve the static content, not dynamic content

eg. Alias /jsp-examples "/usr/local/tomcat/webapps/jsp-examples/"

To get the static content, you don't even need to configure mod_jk

Straight, Forwarded and Focused.

Short comment thought:

In case U're using Virtual Host tags then the following will not work for U:
Test Apache/Tomcat integration by going to http://Web_server_name_or_IP/jsp-examples and http://Web_server_name_or_IP/servlets-examples

Assuming that
Web_server_name_or_IP = Your_Virtual_Host_Name

To make it happen U need to place JkMount lines within Virtual_Host derectives tags.

Thank you so much. Was going thru so much pain trying to get tomcat to work on apache server until I ran into your how-to. Thanks.

2008-01-10T01:15:00.000-08:00

Nice article but if you still have problem running your java applications on apache2 with mod_jk connector just make a slight change..viz, use ajp13 worker rather than default, ajp12. good luck.

Thanks a lot. It worked for tomcat6 too.

2007-12-10T10:02:00.000-08:00

dbspace -- to point apache to a tomcat instance on a different machine, you need to specify that machine in your workers.properties file.

Example:

worker.app2.port=8010
worker.app2.host=remote-host
worker.app2.type=ajp13
worker.app2.lbfactor=1

In this case, worker app2 is directed to remote-host.

as u have written in the documentation ........that static content is served by the apache it is gettting served .......
and jsp content is getting server by the tomcat using connector.......

but in case of jsp files the tomcat is showing the 404 error.......
i know what this error exctly means...........

Thanks for posting this wonderful article.
I found tomcat jsp examples if I only added "Alias" part(of course with directory tag) into the httpd.conf.
I don't know what is wrong? why I don't even need mod_jk.so.

Thanks,

Hi,
First of all thanks so much for helping us get through the pain of configuring Apaceh2 and Tomcat 5.5 with mod_jk. However I am running into certain issues.

1. I am having a apache loadbalancer in place and I am using ssl. My ssl.conf file has the necessary ssl parameters. Now the issue I am actually facing is:
Say the name of my application is ABC which is placed under /opt/tomcat/webapps/ABC.

The ssl.conf file has following entries in Virtual Hosts section:

DocumentRoot "/opt/static" #Static content is served from here.

JKMount /ABC loadbalancer
JKMount /ABC/* loadbalancer

Now when I type https://ip-address/ in the browser, then the welcome page defined in web.xml of ABC application gets displayed (this is a login page). When I enter the username and press submit ideally /ABC/login.do should be called. However when i checked the apache logs, it showed that /login.do was called instead of /ABC/login.do. Basically this request was not forwarded to tomcat.

However this works well when I enter https://ip-address/ABC in the broswer. Following this all calls are made in the proper way. i.e /ABC/login.do was called.

2. I am no getting any entries in mod_jk.log, Like the worker was looked up and stuff.

3. I have another application PQR in webapps. I have configuerd this application on another ip-address on the same machine.
There is another virtual host entry for this :

However when i try to access the application on this ip-address, the other applictaion ABC gets displayed. However if I type

https://ip-address2/PQR then this applictaion works fine.

Request you guys to help me sort this out.

Thanks in advance.

I did it everything . I also got the connection, but I can only load pages which are static. I can't load jsp pages

Not sure what's going on with your configuration. ...

Not sure what's going on with your configuration. You may want to try installing mod_jk from an RPM:

2007-06-08T17:36:00.000-07:00

Grig:

I finally find a RPM package with apxs in it. And I install the package successfully in my server. [root@nexant-pl man8]# rpm -ql apache2-devel | grep apxs2
/usr/sbin/apxs2
/usr/share/man/man8/apxs2.8.gz

However, I don't know if I need to do "Make" or "make install" in order to make apxs2 take effort. I check by typing >man apxs2, it does not come up. And I do the following in the JK connector folder:
./configure --with-apxs=/usr/sbin/apxs2

and get the same error :
could not find /usr/sbin/apxs2
configure: error: You must specify a valid --with-apxs path

Do you know if I miss anything to make the apxs2 takes effort in my server?

Grig:

I still did not get through my problem because Redhat does not has dpkg. I search the web but can't find a file to allow me install dpkg to Redhat.

Would you please tell me the URL where you download your APACHE 2.0.55? It seems that your apache2 does come with apxs in its /bin folder. As I mentioned, I download both apache 2.2.24 or 2.0.59, either them come with apxs2.

Thank you very much.
