Handle default page (mixing mod_cluster with mod_rewrite )

lowecg2004 Jul 28, 2009 7:41 PM

I feel a bit embarrassed asking this because I can't help thinking this has a simple solution and is something that I should know, but...

Back in the day, with mod_proxy and a single instance of JBoss, I used to use the following mod_rewrite rule to handle the default page in my virtualhost:

RewriteEngine On
 RewriteCond %{HTTP_HOST} ^cluster\.domain\.com [NC]
 RewriteRule ^/$ /index.html [PT]

Now I'm using mod_cluster, I cannot get this to work. When hitting the URL http://cluster.domain.com/ I just get a 404 from my application. Logging from mod_rewrite says that the rule has matched, but it doesn't make its way through to JBoss.

BTW - if I enter http://cluster.domain.com/index.html then my app picks this up fine.

In my application's web.xml I've also tried:

<welcome-file-list>
 <welcome-file>index.html</welcome-file>
 </welcome-file-list>

But no luck (not even using JBoss directly). I've even tried various combinations of DirectoryIndex in http.conf - again nothing.

Can anyone offer any pointers on how to handle this? I've spent far too long on this and I'm waving a white flag in total utter defeat.

Cheers,

Chris.

you want / or /index.html to be mapped to your application in JBoss so it must be the ROOT webapp (server/default/deploy/ROOT.war), once it is working in JBoss directly you should remove the Rewrite directives.

I already have the following in my web app:

<jboss-web> ... <context-root>/</context-root> <virtual-host>cluster.domain.com</virtual-host> </jboss-web>

Shouldn't that be enough? The context is working okay, it's just a question of getting a default document to be served.

I'll focus on getting this working directly...

Thanks for the reply.

Fixed it.

In order for <welcome-file-list> to be recognised, web.xml file also needs to have an additional servlet mapping that matches with the welcome-file entry. For example:

<servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>/index.html</url-pattern> </servlet-mapping> ... <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list>

Not so obvious after all?

I have created a JIRA: MODCLUSTER-86
Note that is it only a related problem.

Cool - although I've managed to resolve my use case, having mod_cluster interact appropriately with mod_rewrite will be very handy.

Thanks for your time,

Chris.
