Spring 2.0 has marked a major advance in the Spring Framework. While still maintaining backwards compatibility, this release adds quite a few new features. What are those features and how do they add value? Come by and see.

In this session we'll provide a practical tour of what's new in Spring 2.0. Spring 1.x users who are looking to upgrade to Spring 2.0 will love this session. If you're not using Spring already, this talk will give a great overview of the things you're missing out by not using Spring 2.0.

The talk will highlight new configuration strategies, Spring AOP, bean scoping, JPA support, JMS improvements, new Spring MVC features, VM languages, and much more.

An Enterprise Service Bus (ESB) brings flow-related functionality such as message routing and transformation to a Service-Oriented Architecture. An ESB also provides a layer of abstraction with endpoints for various protocols and transports. These features promote decoupling of integration logic from business functions, flexibility in the transport layer, and pluggability of POJO services.

While ESB is a vast topic, this session will offer a glimpse of a few technologies (scheduling, messaging, and remoting) within the context of an ESB. The content will be heavily example-based with a good deal of code and configuration. The emphasis will be on Spring's enabling role for implementing POJO-based solutions that achieve flexibility in the face of the constantly changing requirements of enterprise integration.

Spring 2.0 introduced support for Message-Driven POJOs meaning that it is now possible to receive JMS messages asynchronously and delegate the handling of those messages to simple objects even within a lightweight application running outside of any application server. If your POJO has a return value, it will automatically be sent to a response destination.

After a quick overview of Spring's JMS support, we will build a Message-Driven POJO sample application from the ground up. This will include sending a Message as a request and receiving a reply across separate JVMs. You will learn how to configure the Message-Driven POJO without writing a single line of messaging code. You will also learn how to configure the pool of concurrent consumers and integrate with Spring's transaction management. We will use the JMS namespace available as of Spring 2.5, and we will even explore the possibility of delegating to a Groovy-scripted object.

Spring Security (formerly known as 'Acegi') enables self-contained, consistent, and extensible solutions for securing your applications. Version 2.0 provides major enhancements including a domain-specific XML namespace, convention-based defaulting, and annotation support. This provides a significantly simpler experience for developers while still supporting the same degree of flexibility.

Spring Security's interceptor-based approach is non-invasive even when extended to accommodate domain-specific requirements. The two main security processes (authentication and authorization) are decoupled in order to provide flexibility across a wide variety of providers and strategies. This presentation will include an overview of Spring Security's pluggable authentication process and how it accommodates a wide range of possibilities including Database, LDAP, Single Sign On, and even an in-memory option for development and testing. We will then proceed to cover authorization where you will see its consistent approach for securing web requests and method invocations. Throughout the session, we will walk through a sample application that demonstrates Spring Security's core features.
