I was pushing out the magnolia-railo-demo and was looking at the site performance. It was amazing by itself, sending back magnolia-railo built pages in 100ms including wire time from Portland to Dallas raw from Tomcat. On this box I have one IP though and I wanted to use a subdomain for the demo which means proxying vhosts.

When I proxied it through Apache’s httpd it took about twice as long for the page to load! (roughly 130-150ms for the base page) It seemed totally ridiculous… Now in all fairness I’m no Apache expert, but I decided to drop in nginx as a proxy on the front end and its cost as a proxy is nearly unnoticeable. I wouldn’t be able to tell it apart from hitting tomcat directly as far as speed is concerned.

I’ll have to give this a closer look for my other projects…

One slightly tricky thing is that if you need Apache’s ProxyPreserveHost in Nginx you need to use proxy_set_header Host like this:

location / {
   root   /usr/share/nginx/html;
   index  index.html index.htm;
   proxy_set_header Host $host;
   proxy_pass http://127.0.0.1:80;
}

Sometimes I wonder what it will be like when apache’s gone. I will probably find myself cding into /etc/httpd/logs and cat access_log over and over… just to remember old times.

Here is the example app live from Magnolia and Railo Part 2. I fixed something in the config that was blocking import as well… so if anyone tried it let me know.

If anyone is interested in logging in, let me know and I will give you some credentials to log in and poke around.

For some reason, this is performing crazy fast right now. On the order of 100 ms, across the country network lag included, on an extremely underpowered rackspace cloud machine (256 megs of ram, running mysql, php, httpd, ngnix and tomcat for this app).

Turn on your firebug or chrome inspector and compare it to your CMS…

I defy any other pure Railo/CFML CMS from topping that for a single uncached hit with three custom cf paragraphs…

This is part two in a three part series on how to make Magnolia CMS and Railo work together beautifully.

If you missed part one you’ll need to have read it and done all steps to get anything out of this.

Step One: Wipe out your repositories folder

We’re starting over with content, so at this point I am assuming you dont have anything in your website tree that is not replaceable. If you have something you want to keep, export it first. This is /repositories in the webroot by default, and is the location that magnolia has stored its derby database. Delete it.

Step Two: Get the magnolia-railo-sample files

Export some sample files and configuration with subversion.

svn export https://www.joshuafrankamp.com/svn/incubator/magnolia-railo-sample/trunk/ tempWebroot

Step Three: Merge the sample files

Copy the contents of tempWebRoot into your webroot, this will overwrite the two files we wrote last time, and add many more.

Step Four: Start up your container

Bootstrapping of the app will occur. While it does, lets go over some of the files that I have prepared for you in this sample.

1. Adding a template renderer
   1. config.modules.templating.template-renderers.cfm.xml
   2. This is required to bind the cfm type to a backing class. We will use the JSP renderer, because it is a dispatch model that is native to Railo since it is a web app.
2. Creating a template definition node, and backing cfm
   1. config.modules.templating.templates.sampleTemplate.xml
   2. template.cfm with some assets/ that it needs to render properly
   3. This is a specific template instance, that in a normal magnolia application would represent one of many template choices. For this example, we will create a simple template.
3. Creating a cf include paragraph definition, dialog, and backing cfm
   1. config.modules.templating.paragraphs.cf.xml
   2. config.modules.templating.dialogs.cf.xml
   3. cfinclude.cfm
4. Creating an example content style “Whats New” paragraph, dialog, and backing cfm
   1. config.modules.templating.paragraphs.whatsNew.xml
   2. config.modules.templating.dialogs.whatsNew.xml
   3. whatsnew.cfm
5. Creating a page dialog, this will be an editor for page level properties
   1. config.modules.templating.dialogs.page-properties.xml
6. Example Page
   1. website.index.xml
   2. This page uses the sampleTemplate, and pulls in the example paragraph types in paragraph instances that show them off.  It also allows access to the page properties dialog.
7. Magnolia Tag Libraries
   1. cms-taglib.tld
   2. These are typically in the magnolia jars, but we need them out where CF can get ahold of them.

Step Five: Hit /index

Magnolia will render the node at the path /index. Since this node is configured in the magnolia administrator to use the simpleTemplate template, it will include the definition of that template to render the page. The templatePath for simpleTemplate is /template.cfm which is a traditional CFML file on disk. At this point the standard Railo request lifecycle will start, including Application.cf(c|m). Then the file will execute, with one signifigant difference. The magnolia context has been set up, and some request scope variables have already been set for easy access to magnolia state information about the page.

A few notes about parts of the example template.cfm

• The tag libraries give simple access to magnolia controls and data structures. These allow you to render magnolia chrome inline in CFML.Example:

  <cfimport taglib="/tags/cms" prefix="cmsmod" />
  <cfimport taglib="/META-INF/cms-taglib.tld" prefix="cms" />

• There are three ways to read information from the content repository. The tag library, request scope context objects, and instantiation of singleton magnolia api objects. They all get the information from the same underlying jcr, but with varying levels of complexity and power.Example:

  <cms:setNode var="page" />...
  <title>#page['title']#</title>

  This pulls the properties from the current content node into a Java Map (struct) whose keys and values give you access to the properties. You can also get at the same information through request['state'] which the reader could dump out and traverse to find all kinds of wonderful things in the api

• Paragraphs are at the heart of everything in Magnolia. They are the single reason for having templates, is the content you want to put on them. By default, Magnolia dispatches the requests for paragraphs to paragraph handlers which in turn for Java technologies, dispatch them as includes through the web app container. This is the point of failure for a technology like Railo, because each request in Railo assumes that it is the beginning and end of that request. It tries to read multi part data on the inbound request, it tries to set headers and response sizes on the outbound response. That is problematic for paragraphs and a big sticking point in the integration between Railo and Magnolia, and it is also not a problem anymore!
  Fortunately, Railo includes its own custom tag concept, and it is simple to implement around the problem. Replacing container includes with calls in a reimplementation of (contrary to its name, this is the tag responsible for including paragraphs, not templates). Look for <cmsmod: includeTemplate /> custom tag calls, in a different namespace. That is the custom implementation of the <cms:includeTemplate /> that would have required going outside the current Railo request.Example:

  <div id="center">
  	<cms:contentNodeIterator contentNodeCollectionName="main">
  		<cmsmod:includeTemplate />
  	</cms:contentNodeIterator>
  	<cms:newBar contentNodeCollectionName="main" paragraph="cf,whatsNew" contentnodename="mgnlNew"/>
  	<hr />
  </div>
