Re: Configuring which Servlet is invoked
Chris, I'm going to leap into the middle of this discussion. Please feel free to discount what I'm going to say since I've just briefly glanced at the Roller 5.0 RC2 documentation. From what I understand, the intent is to have one Roller application running as the default web application (ROOT) on a Tomcat server, and have it be the default application for multiple blogger domains. From the Wiki page, Roller will handle multiple domains with one application by referring to a properties file, such as: # roller-custom.properties weblog.absoluteurl.photophys=http://photophys.com weblog.absoluteurl.alex=http://greenimp.me weblog.absoluteurl.linus=http://linusjohnson.com I'm guessing that somewhere in the Roller application these absolute URLs are mapped to internal URLs. Maybe this works like an internal mod_rewrite? I don't know, since I haven't looked at the code. Let's assume for a minute that Roller acts as if it has its own URL rewrite engine. If that's the case, then all Tomcat has to do is deliver the multiple URLs to the same application. In other words, photophys.com, greenimp.me, and linusjohnson.com should all be delivered to the ROOT web application of the default host, and Roller will figure out what to do from there. If that's the case, then what I think you need are aliases along with the default host definition. So using the above example, the following Host element can be constructed: Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Aliasphotophys.com/Alias Aliasgreenimp.me/Alias Aliaslinusjohnson.com/Alias /Host You'll have to set up all aliases to resolve to the same IP address that is your host. For testing, this can be done in the hosts file. In Linux it's /etc/hosts as long as your nsswitch.conf includes files for host resolution. In Windows/XP (don't know about other versions), it's in Windows\system32\drivers\etc. Hopefully Roller will do the correct thing internally. Fronting this with Apache httpd should not be too difficult if the above works. Basically, you'll use name-based virtual hosts with mod_jk (or mod_proxy_ajp) to map / and /* back to the same Tomcat server. Again, hopefully Roller will figure things out with the Alias elements. If I'm completely off base, please forgive the rambling. Again, I've not played with Roller (and this appears to be a release candidate), not looked at the source code, nor done more than skim one web page and the PDF docs. . . . just my two cents. /mde/ - Original Message From: Christopher Dodunski chrisfromsquir...@christopher.net.nz To: users@tomcat.apache.org Sent: Mon, October 11, 2010 9:20:48 PM Subject: Re: Configuring which Servlet is invoked Catalina logs contain some entries that may shine some light on the matter...

Re: Configuring which Servlet is invoked
Hi, Thank you André for your clear explanation below. I am aware already of how the directory structure relates to URL formation and, thanks to you and others, now understand the significance of Host elements within an Engine. And I see how the default host is configured. It doesn't, though, quite answer my particular issue. Apache Roller is a weblog server, that handles multiple domains - e.g. blog.host1.com, blog.host2, etc. But, at the present time, to correctly form URLs within the HTML it serves up, Roller must run as the default Tomcat application. Therefore, it is installed at /usr/local/tomcat/webapps/ROOT. Here is what is happening: 1) HTTP request comes into my webserver with the URL: http://blog.christopher.net.nz 2) Apache HTTP server receives this on port #80 3) mod_rewrite appends /christopher to the end of the URL of the request header (Roller recognises this as the handle, so it serves up the correct blog page) 4) mod_proxy forwards request on to Tomcat's AJP port #8009 5) Tomcat receives this but, with the current configuration, invokes the application at webapps/christopher. Instead, I would like it to invoke the default (Roller) application at webapps/ROOT. Interestingly, if I browse to another domain hosted by Roller - http://blog.bread.co.nz(/bread) - as I don't happen to have an application at webapps/bread, Tomcat handles this fine. The default application (Roller) serves up the weblog for handle=bread. Thanks regards, Chris.

RE: Configuring which Servlet is invoked
Hi Chuck, The unpacking matter is now sorted - Tomcat didn't have write access. Regarding which is default host, I already have several applications hosted on Tomcat, and these are called by Apache HTTP (proxy) server like so: ProxyPass /tomcat ajp://127.0.0.1:8009/christopher/ ProxyPassReverse /tomcat ajp://127.0.0.1:8009/christopher/ My preference would be to leave localhost/127.0.0.1 as the default host. All applications (except Roller) are installed at /usr/local/tomcat/webapps. Roller hosts multiple domains, and so I can't see how this can be the default host. I thought the best option might be to set up a Host for each domain Roller serves, all with appBase=/home/roller/application. Is this the best solution in your opinion? Thanks, Chris.

Engine name=Catalina defaultHost=localhost Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false /Host The first Host above should be the one running the blogging app; is that correct? Host name=http://blog.christopher.net.nz; appBase=/home/roller/application unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false / Are the appBase settings switched? I would have thought the roller directory would be associated with the blogging webapp, based on your previous descriptions. Have restarted Tomcat, but Tomcat isn't unpacking /home/roller/application/ROOT.war as expected. Does Tomcat have read and write access to that directory? The catalina.out log doesn't seem to give a reason. Possibly the wrong log file to look at. What do the others have in them? - Chuck - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
RE: Configuring which Servlet is invoked
From: Christopher Dodunski [mailto:chrisfromsquir...@christopher.net.nz] Subject: RE: Configuring which Servlet is invoked Roller hosts multiple domains, and so I can't see how this can be the default host. That is exactly the situation where you want it to be the defaultHost, so you don't have to configure a Host per domain. However, that does restrict you to one default webapp servicing all of the domains. Either that webapp or a filter can route each request to the proper domain-related webapps, if needed. I thought the best option might be to set up a Host for each domain Roller serves, all with appBase=/home/roller/application. Not good. You should have a separate appBase for each Host. If you don't, incorrect deployment may occur based on the timing of each Host seeing the webapps underneath the shared appBase. If you run with expanded directories rather than .war files, it may work, but it's not recommended. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Configuring which Servlet is invoked
What I probably omitted to say is that localhost is likely to be associated with many more domains than the Roller application alone. So marrying the default host to Roller isn't likely to save me work. Instead, I have added Alias elements to the Roller host for each blog domain. And so far so good! Roller serves up the bread blog with http://blog.bread.co.nz, and Tomcat no longer invokes webapps/christopher (a localhost app) with http://blog.christopher.net.nz. However, it doesn't appear to invoke Roller either. Instead Tomcat reports The requested resource () is not available. Why is host below invoking Roller for some of the Alias elements, but not all? Puzzling! Host name=blog.optomus.com appBase=/home/roller/application unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Aliasblog.bread.co.nz/Alias Aliasblog.capereinga.co.nz/Alias Aliasblog.doubtlessbay.co/Alias Aliasblog.christopher.net.nz/Alias Aliasblog.isaac.net.nz/Alias /Host Chris. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Configuring which Servlet is invoked
Catalina logs contain some entries that may shine some light on the matter... SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Document base /home/roller/application/optomus does not exist or is not a readable directory INFO: Container org.apache.catalina.core.ContainerBase.[Catalina].[blog.optomus.com].[/optomus] has not been started SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Document base /home/roller/application/christopher does not exist or is not a readable directory INFO: Container org.apache.catalina.core.ContainerBase.[Catalina].[blog.optomus.com].[/christopher] has not been started SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Document base /home/roller/application/host-manager does not exist or is not a readable directory INFO: Container org.apache.catalina.core.ContainerBase.[Catalina].[blog.optomus.com].[/host-manager] has not been started SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Document base /home/roller/application/manager does not exist or is not a readable directory INFO: Container org.apache.catalina.core.ContainerBase.[Catalina].[blog.optomus.com].[/manager] has not been started Is it a Tomcat requirement that additional hosts (appBase) must each contain manager and host-manager? This appBase currently contains ROOT (Roller) only. The first two errors above make no sense to me.
