Adding web application to existing Apache/Tomcat installation

Dear All,

we are trying to add a web application to an already existing installation of Apache/Tomcat but cannot seem to get this to work. Does anyone have a good tutorial or description on how to do this? We are fairly new to the configuration of Apache/Tomcat and are getting a bit confused by all the different configuration files and how they are linked. So any hints, pointers or tutorials on how this is done will be greatly appreciated.

Best regards
Daniel Martinsson

Hi Daniel,

Can you confirm if you are using mod-JK or mod-proxy as the configuration is quite different.

Good morning,

it seems we are using mod-proxy

this is from the httpd.conf file
LoadModule proxy_module modules/mod_proxy.so

There are a couple of things you need to do.
(if you make any changes to server.xml/web.xml you need to restart tomcat if oyu make changes to httpd.conf you wil need to restart apache).

1: Ensure you have your application resources configured in catalina_home/conf/server.xml
(your database resources)
EG:
         <Resource
                name="jdbc/DBNAME"
                auth="Container"
                type="javax.sql.DataSource"
                driverClassName="com.mysql.jdbc.Driver"
                url="jdbc:mysql://localhost/DBNAME"
                username="DBUSER"
                password="DBPASS"
                maxActive="10"
                maxIdle="5"
                minIdle="1"
                maxWait="15000" />

2: Ensure you have your modules configured in catalina_home/conf/web.xml
(mime types and servet mappings):
EG:    
<servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>
EG:
    <mime-mapping>
        <extension>shtm</extension>
        <mime-type>text/html</mime-type>
    </mime-mapping>


3: Ensure you have your app proxy configuration in httpd.conf (apache conf file)
EG:

#Tomcat configuration
ProxyRequests off
<proxy *>
  Order deny,allow
  Allow from all
</proxy>

ProxyPass /MYAPP http://mydomain.com:8080/MYAPP
ProxyPassReverse /MYAPP http://mydomain.com:8080/MYAPP


Here are some links that may help you:

http://tomcat.apache.org/tomcat-6.0-doc/proxy-howto.html
http://www.apachetutor.org/admin/reverseproxies
http://www.ehow.com/how_6108865_configure-apache-reverse-proxy.html

These also have some good documentaion that may be worth you looking at:

Also PSI probe may help you:
http://code.google.com/p/psi-probe/

Deploy the war file. It uses the same username and password as tomcat manager.  connect using: myurl.com:8080 or if you have chnaged the port for manager access it will be: mydomain:myport.
