Welcome to another installment of This Week in Spring. Lot's of good content to go over, this week, so let's get to it.

Also: if you're in Stockholm, Sweden attending the JFokus Java conference, be sure to stop by the VMWare booth to say hi or have your questions answered about Spring, Cloud Foundry, and vFabric.

1. Alan Stewart has announced the release of Spring Roo 1.2.1, which includes fixes for multi-module Maven projects, huge performance enhancements, and updated support for PrimeFaces 3.1 and Google App Engine 1.6.2.

   Last week, Jason Weathersby and <a href="http://blog.springsource.org/author/jolong/">Josh Long</a> put together an introduction to using <a href = "http://www.springsource.org/BusinessIntelligenceWithSpringAndBIRT">BIRT and Spring together</a>.

BIRT's a fantastic technology for doing business intelligence and reporting, and Spring already knows about your data, so connecting them is a natural next step. Enjoy!

	<LI> <a href = "http://blog.codecentric.de/en/author/tobias-flohre/">Tobias Flohre</a> is back with not one, but <EM>two</EM> great posts on Spring! The first, a follow up to his series <a href = "http://blog.codecentric.de/en/2012/02/a-business-component-architecture-with-spring-3-03-1-part-3-properties/">on business component architectures introduces  properties and their use in Spring 3.1</a>. 
		
		The second post, on <a href = "http://blog.codecentric.de/en/2012/02/spring-data-mongodb-geospatial-queries/">geospatial queries in Spring Data MongoDB</a>, is a <EM>fantastic</EM> look at 	
		both geolocation, and the specific application  from <A href ="http://www.springsource.org/spring-data/mongodb">Spring Data MongoDB</a>.

	<LI> The Java CodeGeeks have a great post on <a href = "http://www.javacodegeeks.com/2012/02/oauth-with-spring-security.html">securing your resources with   Spring Security OAuth</a>. 
		 This  post is <EM>not</EM> to be missed!
