Acegi Security Framework for Spring Tips

Over at Craig's stack trace, Crag has a nice post on a terse configuration for the Acegi Security Framework for Spring.

Now that version 0.7 of Acegi is out, I had to make two small changes to Craig's acegi-common.xml file. This file holds all the default and stock beans needed for a generic install of Acegi. By moving all the boilerplate config out of the main configuration files, Acegi suddenly becomes usable.

To make this config work in the Acegi 0.7 + Spring 1.1.4 world, you must make (at least) two minor modifications.

First, for all the beans in acegi-common.xml that will be redefined in your application specific security configuration, you must add the attribute abstract="true". This is in addition to lazy-init="true". The abstract attribute forces Spring not to load up the bean, even if another bean references it. This is the case in acegi-common.xml where the httpSessionIntegrationFilter bean references other beans.

Which brings me to my second tip. You need to change the AutoIntegrationFilter reference to HttpSessionIntegrationFilter (or another IntegrationFilter of your choice). In version 0.7 of Acegi, the AutoIntegrationFilter has been removed.

It all seems to be working, now!

Lists and arrays in Dart

(This is Part 3 in a series about Dart. Check out Part 2, Function in Dart .) Warning : We expect the Dart libraries to undergo potentially sweeping changes before Dart goes to alpha. This document is relevant as of 2011-12-22. Intro Dart is a "batteries included" effort to help app developers build modern web apps. An important "battery" is the bundled core Dart libraries, providing common and rich functionality. Dart is building a solution for large, complex web apps, and providing well tested, integrated, and common libraries is key to helping a web app developer be more productive out of the box. The Collection libraries are a crucial set of APIs that Dart developers get for free. Much more than simple arrays and maps, the Collection library includes standard ways to filter, iterate, inspect, compose, and sort your data. This post specifically looks at List<E> , Dart's ordered, indexable collection of objects. Aside: The Dart project is lucky

Converting Array to List in Scala

Now, this has to have a built-in somewhere in Scala , because it just seems too common. So, how to convert an Array to a List in Scala? Why do I need this? I needed to drop to Java for some functionality, which in this case returns an Array. I wanted to get that Array into a List to practice my functional programming skillz. **Update**: I figured out how to convert Arrays to Lists the Scala way. Turns out it's a piece of cake. val myList = List.fromArray(Array("one", "two", "three")) or val myList = Array("one","two","three").elements.toList The call to elements returns an Iterator , and from there you can convert to a List via toList . Nice. Because my first version wasn't actually tail recursive, what follows is a true tail recursive solution, if I were to implement this by hand. The above, built in mechanism is much better, though. object ArrayUtil { def toList[a](array: Array[a]): List[a] = { d
