Railo and Magnolia CMS are finally together. It’s been a bit of a bumpy road, what with issues arising immediately when they first met. A casual observer might think the relationship was doomed. But a funny thing happened over the course of the last year, Railo changed for the better and for that matter so did Magnolia. I’m proud to say they’ve even moved in to the same bulding at JBoss (in a matter of speaking). From what I hear the landlord thinks the world of both of them but they have still led separate lives.

Until now.

This will be the first in a series of magnolia-railo merged app tutorials. Part one will walk through the merging of the two web apps into one. Part two will show how to enable Railo templating and explore the interaction between Magnolia and Railo. Part three is about the dark side, potential problems and workarounds.

Before we dive in, I will address the question “why should these two technologies be merged?” It is simple really. Magnolia is a superior CMS to anything offered in the CFML world, and has amazing interoperability with other technologies. Railo on the other hand, blows the pants off any of the native templating options available in Magnolia and its rapid and powerful tag based language easily unlocks the power of Magnolia’s Jackrabbit JCR. In short, they were made for each other.

Lets put these two together:

1. Download the latest railo custom all os war, extract to /merge-target. I’ll refer to this directory as the location of our new merged app, however you can name it what you wish.
2. Delete these files from /merge-target/WEB-INF/lib These files overlap with magnolia’s jars.
   1. apache-jakarta-commons-codec.jar
   2. apache-jakarta-commons-collections.jar
   3. apache-jakarta-commons-fileupload.jar
   4. apache-jakarta-commons-httpclient.jar
   5. apache-jakarta-commons-io.jar
   6. apache-jakarta-commons-lang.jar
   7. apache-jakarta-oro.jar
   8. apache-lucene.jar
   9. backport-util-concurrent.jar
   10. concurrent.jar
   11. PDFBox.jar
3. Download the latest railo patch (currently 3.1.2.006.rc). Put it in /merge-target/WEB-INF/lib/railo-server/patches/
4. Download Magnolia Community Edition war extract to /magnolia-temp
5. Copy /magnolia-temp/WEB-INF/lib/* to /merge-target/WEB-INF/lib/* There should be no file name conflicts.
6. Copy /magnolia-temp/WEB-INF/config to /merge-target/WEB-INF/config
7. Merge web.xmls. Use Magnolia’s xml header with namespaces! It doesn’t like anything else, because it reads it in at runtime. Here is the one I created:

9. Set magnolia.update.auto=true in /WEB-INF/config/default/magnolia.properties
10. Start your container such as tomcat.
11. Go to /.magnolia, login superuser/superuser
12. Navigate to Configuration. server->filters->bypasses. You will see the railo node appears, in the configuration bypasses. If you inspect it you will see it is a uriStartsWithVoter that is configured with /railo-context. This node gives you bypassing of magnolia filters for any url starting with /railo-context.
13. Because of this you can hit /railo-context/admin/index.cfm and setup railo.

The bypass rule is required because Magnolia controls the url space with its chain of filters. You can right click on it and copy it to make another arbitrary bypass that is applied immediately. The filters are configurable and this gives you flexibility in fronting CFML apps with arbitrary urls configurable at runtime. At this point you can build anything you want using Magnolia’s built in templating. The bypasses allow you to run standalone CFML apps in the same JVM, under specified url paths (/myapp/*).

That is it for part one. The next article will highlight how your templates and paragraphs can be built in standard CFML, and the interaction between Magnolia and Railo.

Earl Grey Ice Cream

• larger ziploc bag (1 gallon or 1 quart)
• smaller ziploc bag (1 pint or 1 quart)
• ice
• salt (rock preferred)
• 2 earl grey tea bags
• 1/2 cup water
• 1/4 cup whipping cream
• 1/4 cup whole milk
• 1 tablespoon sugar

Heat the water to boiling, pull it off the heat and put in the tea bags. Let it steep for a few minutes, pull out the tea bags. Squeeze the teabags and attempt to get all the flavour out into the liquid, it should be dark brown.

Put the concentrated tea, sugar, cream and milk in to the smaller bag and seal it.

Pack the larger bag 1/3 full of ice and salt, place the smaller sealed bag into the larger bag, place more ice and salt on top. The goal is to completely surround the smaller bag with ice.

Shake for about 10 minutes or until inner bag is ice cream.

Eat the best ice cream in the world!

You’ve been waiting for it! You’ve been porting to other solutions! But wait! here it is!

svnant 1.3 with subversion 1.6.X support.

Tigris happens to be doing maintainence now but it will be up there soon too.

At work I am troubleshooting apache/tomcat/coldfusion/magnolia stack on windows. It is the most fun thing you can imagine. I was messing with apache’s configuration on mod_proxy_balancer and I needed to a way to test if my settings were having the desired effect.

I ran into a *nix shell script that did this, but not one for windows. This is super simple way to count connections against your localhost’s port 80, web server. It shows established and waiting connections.

Save this as a  .bat file and it will output them. It could be optimized in a number of ways, but who cares!


echo port 80:
netstat -a -n | find "TCP 127.0.0.1:80 " | find /C "ESTAB"
netstat -a -n | find "TCP 127.0.0.1:80 " | find /C "TIME_WAIT"


Dear open source software community,

Utilities are an important part of programming packages. It is commonly held that a utility class be one with static methods; the association that they may hold may be as simple as the type they operate on. 

A utility for manipulating strings may be called StringUtil or StringUtils. There is no consensus on this in the community.

If you hold that each method in the class IS a utility, you would probably assume the class should be named StringUtils. (like apache lucene, apache commons, spring)

If you hold that the class itself is the utility, bound together by its common association. Each method is simply that, a method in the utility that operates on strings, you would probably assume the class should be named StringUtil. (like apache lucene, apache poi or jetty)

Thats right, in lucene they can’t even decide within the same project…

They have packages named util and utils, and utilities name SUBJECTutil and SUBJECTutils.

Kind of like my codebase at work… As soon as you decide.. can you let me know?

- Joshua

Update: At my work developer poll ”util” has it. Three to one with one abstaining.

My home network gateway is a busybox (linux) based openWRT router running on linksys wrt54g hardware. I’ve been playing with its many built in and package based features, via ssh and a web based portal. For my next version I think I can dump the web based portal and go strait for the pure ssh only distribution.

My router is actually not a router at all anymore, it is an embedded computer with a wireless adapter (or two?) and a fully configurable switch, set up in client mode, using its wireless adapter to search for open wifi nodes and connect. Then it nats up a wired network (which my 800 foot condo has 14 ports) for the rest of my computers.

I realized just how cool it was when I was adding a crontab entry to do connection detection and reconnect and it opened up vi. I don’t get vi, and don’t care to understand it. I had to go look up how to exit it. I’m not ashamed to say so, its a horrible, horrible invention. Ok so not a horrible invention, but like the telegraph it has served its purpose. Can we move on?

So I cracked open the global profile in zile (light emacs clone) and changed the default editor.

That is when I realized, this is cool. I have not one, but multiple editors on my router. Other packages that are available are traffic shaping, upnp, various kinds of vpn, torrent clients among other things.

Next I am going to move on to my home backup/file server/torrent machine which will probably be an openwrt box as well. This time its running on a 1 watt solid state linksys NSLU2, spinning up a hard drive when I want to stream or backup something, but mostly relying on a large usb flash drive for torrenting. The NSLU2 and the router combined will be a super low power ‘always on’ computer for my home. Yay!

I pushed some buttons and opened up part of my svn repository to share the code from my earlier example:

https://www.joshuafrankamp.com/svn/incubator/simpleGroovyCalendar/src/

I read up on groovy’s site, about google data support but I actually couldn’t find the referenced code anywhere… I’d like to learn more about ‘use’ and other aop/mixin techniques.

I fixed a few bugs in this release. One was dealing with remote info requests against files. A couple others were from updated subversion 1.5, and new svnant dependencies. I added a cleanup task, contributed to Oleg Byelkin.  Writing the tests for that was a little bit of a trick due to the fact that cleanup (in order to be succesful) needs to have a messed up working copy… so I settled for writing a lock file to the .svn/ and calling it succesful if it removed it.

svnant-1.2.1.zip

The other day I was talking to some coworkers about a groovy method that I had refactored. It was one that I had pulled the guts out because I needed two forms of the same data. So I added getDaySizeList which contains most of the logic, but I still needed to get a rollup sum from getDuration for another part of the application.

I knew groovy collections supported an “each” function that takes a closure. Groovy syntax allows for omission of parentheses when there is at least one argument, so it can look like this:

myCollection.each{ closure } not myCollection.each({ closure })

it would also allow you do things like:

myCollection.add object  (look no parens!)

which creeps me out right now, so I’m not going to think about it.

I digress… Here is my method, that I thought was a short implementation:

int getDuration(){
	int hours = 0;
	getDaySizeList().each{dayHourMap -> hours += dayHourMap.hours}
	return hours
}

I was excited, no visible loop, just something to do “each” for the members of the collection, drilling down into the hours property of the map in each collection item, summing them into a waiting “hours” int, then returning it. Slick.

Barney then replied that I should have (duh) used the sum closure-taking builtin in groovy… which turns the above method into this:

int getDuration(){
	return getDaySizeList().sum{it.hours}
}

“it” is the default single argument to the closure.  You can see I only kept the end of the closure, to the right of the former +=.

Magic.
