Can not access Tomcat applications

[NetWorm]

In any case I installed Apache and Tomcat and I've linked: this means that when I go to the address http://my_server/ I go directly to the page of tomcat without having to specify port

Now the problem is that I can not access the applications managed by tomcat and that I had before in apache no longer available

Do you know what conf file works correctly, in my apps in Apache and Tomcat?

[Zecho]

I would say httpd.conf ...

Type a document root that refers to your application handled by Tomcat
VirtualHost and possibly other ports that refer to other directory. (with alias etc)

For instance, suppose you have a HTTP Server that listens to the 80 and 443
The 80 refers to the root server in PHP + MySQL and several virtualhost
The 443 refers to the implementation in HTTPS on Tomcat with the addition of a URL rewrite to be visible on the field

Here is the code of file sites-enabled/000-default

<VirtualHost 192.168.1.2:80> 
ServerName 192.168.1.2 
DocumentRoot /usr/share/tomcat5.5/webapps 
ServerAdmin webmaster@foobar.com 
ErrorLog /var/log/apache2/error.log 
CustomLog /var/log/apache2/foo.log combined 

Alias / "/usr/share/tomcat5.5/server/webapps" 
<Directory "/usr/share/tomcat5.5/server/webapps"> 
Options Indexes +FollowSymLinks 
</Directory> 

JkMount /* default 

#Alias /websvn "/usr/share/websvn" 
#<Directory "/usr/share/websvn"> 
# Options FollowSymLinks 
# order allow,deny 
# allow from all 
# AuthType Basic 
# AuthName "Subversion Repository" 
# Require valid-user 
# AuthUserFile /etc/apache2/dav_svn.passwd 
# <IfModule mod_php4.c> 
# php_flag magic_quotes_gpc Off 
# php_flag track_vars On 
# </IfModule> 
#</Directory> 

</VirtualHost>

I am very unsure whether I should enter httpd.conf

mod_proxy or mod_ajp13 in Apache ?

JkMount /* default

That means that you are referencing all to the tomcat

[NetWorm]

Yet I have configured mod_jk. And for "JkMount /* default", that's what I noticed. I have played with JkMount and JkUnMount to balance traffic to the right server.

Thank you for your help
