The Melbourne Spring User Group will have three presentations:

• Ben Alex will be presenting, "Web Security Success with Spring Security 2":

Most enterprise applications are multi-user systems dealing with business-critical corporate data. Such applications generally require a security approach that addresses user identification and their permissions.

Spring Security 2 (formerly known as Acegi Security) is the Spring Portfolio's security module, and is widely used in security-critical environments such as banking, finance, defense and government departments. Spring Security frees application developers from the time-consuming and complex work of securing their applications, with out-of-the-box capabilities including authentication, authorization, domain object access control, human user detection, channel switching and so on. As such, Spring Security significantly reduces the cost and risk of securing enterprise applications, while also providing a robust, production-proven solution that is extremely flexible to current and future requirements.

This session is aimed at introducing Spring Security to those not already using it, or those wishing to gain a wider appreciation of what it can do in typical enterprise applications. Ben demonstrates adding Spring Security to an existing web application. This shows you to configure and deploy Spring Security. He'll also briefly discuss the features most commonly used in web application deployment scenarios, single sign on, channel security enforcement (HTTP vs HTTPS), custom method authorization security, Ajax integration, and other considerations of web application security.

This presentation will feature a lot of live demos and code, so sit back and enjoy!

• Adam Boas will be presenting on Flex 3 and Spring

• Larry Liang will be presenting on the new open source BlazeDS system and Spring

Refreshments are available from 5:30 pm, with the presentations kicking off at 6:00 pm. All presentations will be completed by 8:00 pm, after which attendees are invited to further refreshments.

There is no cost involved, and refreshments (tea, coffee, juice, beer, wine etc) will be provided courtesy of Renewtek. There will also be some extra drinks and nibbles when the evening's formal presentation wraps up.

You do not need to be a member to attend. You simply need to register via this web site, so that we can ensure there is sufficient seating and refreshments for those interested.

Your registration record will not be shared with anyone. We'll only use it to print your name badge, and add you to the Australasia Spring Interest list (so that you know about future Spring user group meetings and similar events in our region, as well as any potential changes to this event's details).

Please note that registration is on a first-come basis, as seating is limited at this event. Therefore, kindly register ASAP to secure your place. Also, please let us know (email office_au@springsource.com) if you can't attend so that we don't keep your place reserved. Unfortunately late registrations cannot be guaranteed seating, although we'll always do our best to accommodate you.
