Tomcat5, Apache2 and mod_jk!

[honey bee]

Hello!

I am trying to execute JSP with apache.I am working on FedoraCore-4 and have tomcat5, apache2 and mod_jk already installed.

Apache and tomcat are working fine, but when i try connect them using mod_jk i don't get the correct execution of pages.

For Examples, if i execute http://localhost/jsp-examples/dates/date.jsp, i get the following result:

<%@ page session="false"%>

    * Day of month: is
    * Year: is
    * Month: is
    * Time: is
    * Date: is
    * Day: is
    * Day Of Year: is
    * Week Of Year: is
    * era: is
    * DST Offset: is
    * Zone Offset: is

, while if i execute the same example as http://localhost:8080/jsp-examples/dates/date.jsp, the results are:

#  Day of month: is 3
# Year: is 2006
# Month: is July
# Time: is 17:24:20
# Date: is 7/3/2006
# Day: is Monday
# Day Of Year: is 184
# Week Of Year: is 27
# era: is 1
# DST Offset: is 1
# Zone Offset: is 5

I have made the following additions to the files.
1. httpd.conf:

Include conf.d/*.conf

<IfModule mod_jk.c>
   JkWorkersFile "/etc/httpd/conf/workers.properties"
   JkLogFile "/var/log/mod_jk.log"
</IfModule>

<IfModule mod_jk.c>
     Alias /jsp-examples "/usr/share/tomcat5/webapps/jsp-examples"

     <Directory "/usr/share/tomcat5/webapps/jsp-examples">
         Options Indexes FollowSymLinks
         DirectoryIndex index.jsp index.html index.html
     </Directory>

     <Location "/jsp-examples/WEB-INF/*">
         AllowOverride None
         deny from all
     </Location>

</IfModule>

2. I have created workers.properties in /etc/httpd/conf, containing:

workers.tomcat_home=/usr/share/tomcat5
workers.java_home=/usr/java/jdk1.5.0
ps=/
worker.list=default

worker.default.port=8009
worker.default.host=localhost
worker.default.type=ajp13
worker.default.lbfactor=1

3. The jk2.properties is all commented file.

4. The server.xml file is:

<Server port="8005" shutdown="SHUTDOWN" debug="0">
 
 <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener"
            debug="0"/>

I have tried several tutorials and solutions on web, but didn't achieved the results.May be anyone can locate from these files what's the exact problem or what needs to be added.

Hi

I too had the same problem... then i inside the virtual host container... have configured like the below items...

Inside the virtual Host container... (uncomment those items which are required..)

# JkMount /* ajp13
# JkMount /jsp-page/* ajp13
# JkMount //* ajp13
JkMount /jspwebpages/* ajp13
# JkMount /pages/* ajp13
# JkMount /trial/* ajp13
JkMount /web/* ajp13

Then restart the apache server... (no need for tomcat)
Then it shud work...

I did the same thing some months backk... using centos + tomcat + apache.
Your other configurations are fine and i think suitable...

Try this method....

Hello!

Thanks a lot for your reply .I have added these lines to the file, but still i am not getting the correct result.

I have placed the jsp-examples folder to my hosts document root.Now i have added the lines to host like this:

<VirtualHost 192.168.0.3:80>
ServerName hinahayat.com
DocumentRoot "/webspace/hinahayat.com/docs/html"
JkMount /jsp-examples/* default
</VirtualHost>

and i also tried this:

<VirtualHost 192.168.0.3:80>
ServerName hinahayat.com
DocumentRoot "/webspace/hinahayat.com/docs/html"

<IfModule mod_jk.c>
Alias /html "/webspace/hinahayat.com/docs/html"

<Directory "/webspace/hinahayat.com/docs/html">
Options Indexes FollowSymLinks
DirectoryIndex index.jsp index.html index.html
</Directory>

<Location "/html/jsp-examples/*">
AllowOverride None
deny from all
</Location>

JkMount /html/jsp-examples/* default
</IfModule>
</VirtualHost>

, but still i am not getting any results.Similarly, when i try to execute the pages through the localhost the results aren't correct.

[honey bee]

Ok,

In my httpd.conf i have added:

<IfModule mod_jk.c>
JkWorkersFile "/etc/httpd/conf/workers.properties"
JkLogFile "/var/log/mod_jk.log"

JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

JkOptions +ForwardKeySize +ForwardURICompat +ForwardDirectories
JkRequestLogFormat "%w %V %T"

JkMount /jsp-examples/servlet/* default
JkMount /jsp-examples/*.jsp default

</IfModule>

and this to my virtual host:

<VirtualHost 192.168.0.3:80>
ServerName hinahayat.com
DocumentRoot "/webspace/hinahayat.com/docs/html"

<IfModule mod_jk.c>
Alias /html "/webspace/hinahayat.com/docs/html"

<Directory "/webspace/hinahayat.com/docs/html">
Options Indexes FollowSymLinks
DirectoryIndex index.jsp index.html index.html
</Directory>

<Location "/html/jsp-examples/*">
AllowOverride None
deny from all
</Location>

JkMount /*.jsp default
</IfModule>
</VirtualHost>

my jsp pages open when i try to execute the page, but don't shows the correct result ann in my mod_jk.log i have the following errors when my localhost execurtes page:

Now, plz help me with this.What needs to be done to solve it out?

[arunr110]

Hi,

I did the mod_jk some months backkk....

so i am not able to give you any options immediately...

I have my document, which describes how it worked... which i used to refer.. often...(at that time)
I put that doc under this place also....
http://rhcenotes.blogspot.com/2006/0...tegration.html

Apache tomcat integration using mod_jk


Install apache and make it work.
(Make sure apache is running on Virtual Host Container)
Make sure tomcat can be started/stopped using scripts
Make sure tomcat is running on port 4000 or 8080 (if jboss is not running on port 8080)
Get the rpm file for mod_jk (mod_jk-1.2.6-3jpp_4fc.i386) (or for AMD 64 bit OS)
Stop Both Apache and Tomcat
Install the rpm mod_jk-1.2.6-3jpp_4fc.i386
Check whether you have the file mod_jk.so under the folder /etc/httpd/modules/
Edit the file /etc/httpd/conf/httpd.conf and include an entry "LoadModule jk_module modules/mod_jk.so" under LoadModule category. (These lines lists all the available modules for the apache server.
Under $TomcatHome/conf create a folder called auto and copy the mod_jk.conf inside this folder. (Get mod_jk.conf by running $rpm -ql mod_jk and subsequent mod_jk.conf.sample file. ($TomcatHome/conf/auto/mod_jk.conf)
Edit mod_jk.conf file and make sure the following entries are fine.
LoadModule jk_module modules/mod_jk.so
JkWorkersFile /etc/httpd/conf/jk/workers.properties
JkLogFile logs/mod_jk.log
(make sure they have the correct path)


Create a folder under $TomcatHome/conf/jk
Copy workers.properties.sample from installation(rpm -ql) and put it here in $TomcatHome/conf/jk/workers.properties

Edit the workers.properties file and make sure the following are edited properly.
workers.tomcat_home=/usr/local/tomcat
workers.java_home=/usr/java/jdk

do not edit anything else.

go to $TOMCATHOME/conf/ and
cp server.xml server.xml.original
cp server-minimal.xml server.xml

Edit the file server.xml and make the port to be 4000

<Service name="Catalina">
<Connector port="4000" />

tomcat part is over..


Just before the Section 3 : Virtual Host container --- add the following three lines..

JkWorkersFile "/usr/local/tomcat/conf/jk/workers.properties"
#JkLogFile "/usr/local/tomcat/logs/mod_jk.log"
#JkLogLevel info
JkLogStampFormat "[%a %b %d %H %M:%S %Y]"

Which tells the location of workers.properties file for apache.

Inside the virtual Host container...

# JkMount /* ajp13
# JkMount /firstwebapp/* ajp13
# JkMount /webapp2/* ajp13
JkMount /webapp3/* ajp13
# JkMount /webapp4/* ajp13
# JkMount /web/* ajp13
JkMount /webr/* ajp13


service httpd start
service tomcat start

access apache by
http://localhost/

and tomcat containers by

http://localhost/webapps/

I used CentOS 4.2 + Apache 2.2 + Tomcat 5.0.18 under a AMD 64 bit processor.

Hello!

Thanks a lot for quick and detailed replies, but still it isn't working.Tomcat5 and Apache2 are already installed in the system.Both are working fine separately.

Even mod_jk was already present, but the connection is not created by it.I have enabled the port in server.xml and also defined it in workers.properties, can't locate the mistake.

I think i must re-install all these and again try the tutorials on web.

Thank you for your concern .

Regards!
