Beta Railo Extensions: CFJAVASCRIPT / CFSTYLESHEET

Wed, 17 Mar 2010 18:24:00 +0200

Another fine example of extending your Railo server by Andrea Campolonghi. Working on large ajax projects it is not uncommon to see pages that include a lot of javascript and css files. We're often times mixing and matching javascript plugins which sometimes has css stylings that go along with the plugins. We have worked to a solution that can help developers and let the server do the job of compressing and concatenating files. Let's imagine that your app need the following js files:

Cache (Reference) Part 3

Fri, 12 Feb 2010 11:44:00 +0200

Before we begin the last part of the cache blog, let's do a little review.

In the first part, I have shown how the cache is used as an object cache, how to create a cache and interact with it but not more. The second part was on everything that is possible with the cache, and for what it can be used. In the last part we want to see at some special cases and deliver the promised reference. [More]

Cache (Advanced) Part 2

Tue, 26 Jan 2010 19:32:00 +0200

In the first part of the cache blog entry we looked at how we can use the cache directly without entering into great detail. Now let's have a look at what the cache is at capable of. Because it provides much more than just storing data. [More]

Cache (Basic) Part 1

Fri, 22 Jan 2010 17:48:00 +0200

Since version 3.1.2 Railo supports the possibility of using a cache. This blog entry will go into the details of this feature. The blog is divided into 3 parts, the first part will deal with the base functionality, the second part show how the cache is used in backend and the last part takes care of specialties when using the cache and shows a reference.

http://projects.getrailo.org/ is now available for those Open Source projects that extend / enhance Railo. Big thank you to Andrea Campolonghi for the time he spent setting this up. If you have a open source project enhancing or extending Railo and would like to have a project hosting along with access to a public SVN and Trac (wiki), please contact us so that we can get you going!

The Ajax Railo project has been relocated to http://projects.getrailo.org/projects/railoajax/.

CFC Custom Tag Example

Fri, 11 Sep 2009 04:20:00 +0200

This post was inspired by Raymond Camden recent blog post about Yahoo Query Language (YQL). Back in June 2009, Michael Offner-Streit blogged about how to create CFC Custom Tags. So, I thought I'd do a little experimenting with this idea and convert Ray Camden's custom tag (cfm) over to a custom tag (cfc) that Railo enables you to use.

Using the Railo cluster cache

Sun, 02 Aug 2009 01:25:00 +0200

This is something we wanted to do for more than a year now. We wanted to implement a cache that is reachable from all the servers in a cluster. So here we go... [More]

Railo 3.1: Building your own Built-In-Function

Thu, 23 Jul 2009 14:19:00 +0200

Ever wish you could just install a frequently used UDF to the server since you use it so much? Take any of the numerous UDFs found at CFLib.org for example. How about... QueryRowToStruct()? That's a pretty useful function. Wonder why they didn't build this in? With Railo 3.1 RC, you can build this in yourself. With this blog post, I'm going to outline two different installation concepts, server wide and local context.

First, server wide:

Click on the "Download" link on QueryRowToStruct and you'll be prompted to download QueryRowToStruct.cfm
For server wide installation, you'll want to put this in the following directory:
```
{railo installation directory}/lib/railo-server/context/library/function/
```
Restart the server (I had to, I'm going to verify if this step is really necessary or if it can be fixed :) )

Once installed, I shouldn't have to cfinclude or copy/paste that function anywhere. I can create a test.cfm in my localhost and run the example code on QueryRowToStruct description page.

Now, you may be in a particular situation where you can't have this server-wide because you share the server with other people or because there's a conflict. You could just install it to your local context. Each virtual host you make should have its own WEB-INF directory, so you have a global admin and a local admin.

You would repeat all of the steps above, except for #2, you'll want to install this here instead:

{your website root directory}/WEB-INF/railo/library/function/

Remember, you don't have to use anything specific from CFLib.org. You can write your own user defined function or install the one that you frequently use. I bet this makes you wonder if Railo 3.1 could give you the ability to create your own Built-In-Tag? ;) You can and there's been some changes, so I plan on investigating and outlining in a new blog post. If you want to see if you can figure it out for yourself, you can use Andrea Campolonghi's <cfajaxproxy> as a great example. This example includes installation directions and will only work on Railo 3.1.020 build or higher.

Update: The resin webserver doesn't need to be restarted, but the Railo servlet engine does. You can do this one of two ways, log into the admin portal and click Restart or via code: <cfadmin action="restart" type="server" password="serverPassword">

Modifiers static,final,abstract

All these modifiers are very helpful in java, but do they make sense in cfml? What do you think? [More]

New Feature in Railo 3.1 - cfapplication

Tue, 07 Apr 2009 13:38:00 +0200

Before Application.cfc has been introduced, you had to set all the settings in the application.cfm by using the tag CFAPPLICATION. it is also possible to use the tag CFAPPLICATION outside the Application.cfm. It is not done quit often but it can certainly make sense. [More]

Struct addressing in Railo

Mon, 17 Nov 2008 20:27:00 +0200

There is a major difference in how Railo addresses structs in comparison to the CFML standard. The result is that implicit addressing, (as I call it) works in the CFML standard but not in Railo. This is an issue we are long aware of AND we will NOT fix it. [More]
