A new Spring subproject in the web portfolio:

Spring BlazeDS IntegrationFocus on integrating the open source BlazeDS with Spr ing

M1 - Dec 2008

Bootstrap the BlazeDS MessageBroker as a Spr ing- managed bean (no moreweb.xml MessageBrokerServlet config needed)

Route http- based Flex messages to the MessageBroker through the SpringDispatcherServlet

Expose Spring beans for remot ing using typical Spring remot ing exporterconfiguration

M2 - March 2008

Spring Security integration

Ensure that Spring security can secure any Springmanagedendpoints with credent ials provided by the Flex app

Integration with the BlazeDS MessageService Use Spring configuration to manage BlazeDS

MessageDestinations

Let Spring manage the JMS details

Allows easy communication from Flex clients to Springmessage- driven POJOs

Spring 3.0 REST integration

Provides support for multiple client- types

Flex apps can already consume Spring 3.0 RESTful endpoints through
