[Jon Rose][1] and I have created a new [DZone Refcard][2] called [Flex 4 and Spring 3 Integration][3]. In the Refcard, we walk you through the steps for building RIAs with Flash Builder 4, Flex 4, BlazeDS 4, Spring 3, the Spring BlazeDS Integration, and Hibernate. Whew! That's a lot of pieces! The Refcard covers simple Remoting, Flex & Hibernate integration through Spring (all Java annotation driven and using the new data-centric development features in Flash Builder 4), Pub / Sub Messaging, and Flex and Spring Security. We pack a lot into six pages!

If you want to see recorded presentations / screencasts of some of these things check out:

  * [What's new in Flash Builder 4 for Java Developers][4]
  * [Flash Builder 4 Data Wizards with Java / Spring][5]
  * [Flex 4, Java, Spring, and Hibernate in Flash Builder 4][6]

I hope all of this is helpful. Let me know what you think.
