apache2 & tomcat5 - how to configure VIRTUAL HOSTS & JSP?

Hello,

I have installed my SuSE 9.2 pro with a DHCP server, DNS server, and even LDAP authetication (thanks to help found on this forum!).
At present, I have also intalled my apache2 webserver easily, but I can not figure out how to configure tomcat5 to work with my apache2.
Let me make it clear that I have installed both packages, apache2 & tomcat5, accoding to SuSE's descriptions so I have the usual JSP pages working (/jsp-examples/ and /servlets/), however I do not understand how to configure Apache2 VIRTUAL HOSTS to serve JSP pages.
SuSE as you know comes with a mod_jk rpm which is easily installed and remaining of cofiguration is fairly straigth forward thanks to notes in the /var/ directory.
But even after a lot of time searching and reading I still can not setup the server.

I have tried ProxyPass and ProxyPassReturn as an alternative but that did not work.
And also tried [uri:/domainPath/*] configuration, again, without any lucky.

I swear that I have searched, but it seems that I still missing something!?

What I am seeking is to enable the following VIRTUAL HOSTS (with JSP & servlets) to be processed through tomcat5:

<VirtualHost *:80>

<IfDefine SSL>
SSLEngine off
</IfDefine>

DocumentRoot /srv/www/vhosts/brainpowered.net/
ServerName www.brainpowered.net
ServerAdmin admin@brainpowered.net

DirectoryIndex index.jsp index.html


</VirtualHost>



the default jk.conf (/etc/apache2/conf.d/jk.conf) is as follows:

########################start#############################
# simple configuration for apache (for AJP connector, modul mod_jk.so)

<IfModule mod_jk.c>

JkWorkersFile /etc/tomcat5/base/workers.properties
JkLogFile /var/log/tomcat5/base/mod_jk.log

# Log level to be used by mod_jk
JkLogLevel error

JkMount /servlets-examples/servlet/* ajp13
JkMount /jsp-examples/*.jsp ajp13

# The following line prohibits users from directly accessing WEB-INF
<Location "/jsp-examples/WEB-INF/">
AllowOverride None

</Location>

deny from all
</Location>

</IfModule>

And the workers.properties file is:

#######################start#############################

# workers.properties -
#
# This file provides jk derived plugins with the needed information to
# connect to the different tomcat workers. Note that the distributed
# version of this file requires modification before it is usable by a
# plugin.
#
# As a general note, the characters $( and ) are used internally to define
# macros. Do not use them in your own configuration!!!
#
# Whenever you see a set of lines such as:
# x=value
# y=$(x)\something
#
# the final value for y will be value\something
#
# Normaly all you will need to do is un-comment and modify the first three
# properties, i.e. workers.tomcat_home, workers.java_home and ps.
# Most of the configuration is derived from these.
#
# When you are done updating workers.tomcat_home, workers.java_home and ps
# you should have 3 workers configured:
#
# - An ajp12 worker that connects to localhost:8007
# - An ajp13 worker that connects to localhost:8009
# - A jni inprocess worker.
# - A load balancer worker
#
# However by default the plugins will only use the ajp12 worker. To have
# the plugins use other workers you should modify the worker.list property.
#
#

# OPTIONS ( very important for jni mode )

#
# workers.tomcat_home should point to the location where you
# installed tomcat. This is where you have your conf, webapps and lib
# directories.
#
workers.tomcat_home=/var/tomcat3

#
# workers.java_home should point to your Java installation. Normally
# you should have a bin and lib directories beneath it.
#
workers.java_home=/opt/IBMJava2-13

#
# You should configure your environment slash... ps=\ on NT and / on UNIX
# and maybe something different elsewhere.

Many, Many thanks in Advance!

i have been seeking for a solution and i think this may help others.

As SuSE 9.2 default configuration of mod_jk provides a worker.property file with pre-configured workers (apj12, apj13) we simply need to add jkMount'ers for JSP pages.

in the jk.conf file, i have added the following lines:

# mount all files ending with JSP
JkMount /*.jsp ajp13

# mount all files ending with JSPX
JkMount /*.jspx ajp13

# mount all files that are stored under SERVLET folder
JkMount /*/servlet/* ajp13

because I am using VIRTUAL HOSTS in apache2, i had to amend the configuration for the virtual host as:

<VirtualHost *:80>

<IfDefine SSL>
SSLEngine off
</IfDefine>

DocumentRoot /srv/www/vhosts/brainpowered.net/
ServerName www.brainpowered.net
ServerAdmin admin@brainpowered.net

DirectoryIndex index.jsp index.html

# withdrawing access to configuration folder
<Directory "/srv/www/vhosts/brainpowered.net/WEB-INF">
Options None
Deny from all
</Directory>


</VirtualHost>



additionally, we need to tell tomcat5 where the virtual host's file reside. We do that by amending the $CATALINA_BASE/base/server.xml file. And adding a host description for each VIRTUAL HOST of apache2:

<Host name="brainpowered.net" debug="1"
appBase="/srv/www/vhosts/brainpowered.net/"
unpackWARs="true">
<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="brainpowered.net." suffix=".txt"
timestamp="true"/> -->
<Context path="" docBase="" debug="0"
reloadable="true" crossContext="true" />
<Alias>www.brainpowered.net</Alias>
</Host>

It works for me. And I hope it helps others as well.

Regards,


Nicolas

hello

I have a small problem. I installed tomcat5 on my Suse 10.2 box, and both the apache and tomcat5 is up and running. The problem, now I have, is that I want to create new directories under webapps and put my servlets there so that I can run them from http://localhost:8080/

For instance, the servlets-examples that is in

/srv/www/tomcat5/base/webapps/servlets-examples works fine when I open the browser: http://localhost:8080/servlets-examples/

But now I want to create new directories such as project1.. for other servlets I want to host on my computer. So I created directory under webapps like:

/srv/www/tomcat5/base/webapps/project1

and created the WEB-INF, and classes under WEB-INF, set the right permissions. But when I open the browser, even if I stop and re-start the tomcat5, the url path:

http://localhost:8080/project1

is not accessible. The error I am getting is:

HTTP Status 404 - /project1/

type Status report

message /project1/

description The requested resource (/project1/) is not available.

Why is this happening? How can I fix this? I spent many hours researching it, but without luck.

Can anyone help me? I will appreciate.

regards.
