JBoss 7 Multiple root context web applications

Question

I need to configure two websites: www.foo.com and www.bar.net on my Apache2+ JBoss7.1 environment.

Apache sites configuration example (they're similar each other, except for site name) :

<VirtualHost *:80>
        ServerAdmin     [email protected]
        ServerName      www.foo.com

        DocumentRoot /var/www/foo
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/foo>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        SetEnvIf Request_URI "/photos/*" no-jk
        JkMount / ajp13
        JkMount /* ajp13

</VirtualHost>

In JBoss standalone.xml I have:

<subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false">
            <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
            <connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>
            <virtual-server name="default-host" enable-welcome-root="false" default-web-module="bar">
                <alias name="localhost"/>
                <alias name="www.bar.net"/>
            </virtual-server>
            <virtual-server name="foo" enable-welcome-root="false" default-web-module="foo">
                <alias name="www.foo.com"/>
            </virtual-server>
        </subsystem>

While both apps have jboss-web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <security-domain>java:/jaas/foo</security-domain>
    <context-root>/</context-root>
</jboss-web>

Deploying foo.war results in:

INSTALL: Failed to process phase INSTALL of deployment "foo.war"

Caused by: org.jboss.msc.service.DuplicateServiceException: Service jboss.web.deployment.default-host./.realm is already registered

What's the right configuration? Where is the error?

Solution 1

It was just enough to add foo to my configuration, now working good with mod_jk. I blogged about it: http://fabiobozzo.wordpress.com/2013/02/25/multiple-web-applications-with-jboss-and-apache/

Solution 2

I think that the problem is that you've defined the same context root for the two applications. You can't have two applications with the same context root at the sametime. One possible solution would be to define a different context for each application (/foo and /bar respectively), and use the ProxyPass directive in each Apache virtualhost.

<VirtualHost *:80>
        ServerAdmin     [email protected]
        ServerName      www.foo.com
        ...
        ProxyPass         /     http://yourjbossserver:port/foo/
        ProxyPassReverse  /     http://yourjbossserver:port/foo/
</VirtualHost *:80>

<VirtualHost *:80>
        ServerAdmin     [email protected]
        ServerName      www.bar.com
        ...
        ProxyPass         /     http://yourjbossserver:port/bar/
        ProxyPassReverse  /     http://yourjbossserver:port/bar/
</VirtualHost *:80>

This way you could access your applications directly through the addresses: www.bar.com and www.foo.com, respectively. (Notice that if you have an Apache acting as a proxy, and using it's own virtualhosts, there is no need to define JBoss virtualhost).

A simple but complete example would be (in this case I've configured the jboss jmx-console, running in the same machine as the apache, to be accessible from www.foo.com):

<VirtualHost *:80>
    ServerName www.foo.com
    ProxyPass         /     http://localhost:8080/jmx-console/
    ProxyPassReverse  /     http://localhost:8080/jmx-console/
</VirtualHost>

Notice that you need to add a backslash at the end of the address.

Have you removed the JKMount directive? if you use proxyPass you shouldn't need it. On the other hand, if you don't need the <Directory> directives, remove or comment them. They may interfere with the ProxyPass directive. I've added a simple full configuration example.

I've just noticed that I forgot to add a backslash at the end of the address. So, a part of removing the directives you don't use, make sure to add the backslash (I've corrected the example).

at least now I can see the login form but static resources can't be found and my form isn't working <link type="text/css" rel="stylesheet" href="/myapp/javax.faces.resource/css/login.css.htm;jsession‌​id=yLqJkKu1h7vG6xAen‌​Jn7TvTp.undefined"> How can I send you a pvt message please?

[Toni]

Could you post the new configuration you're using? And about the css, are they in a context different to the application one?

down voted without a comment. classy im ok with it because the difference between the person that down voted it and I is when this was written, what i said was in fact correct. I was running multiple sites on the same instance mapped with that same configuration. go test it before you down vote it next time.
