Spring MVC is a powerful and flexible framework for building web applications. Its interface-based API promotes loose coupling, yet it also offers many convenient base classes for common functionality. Whether you use the base classes or roll your own, you will discover numerous strategies and extension points. This flexibility will be greatly appreciated once you are up to speed, but newcomers often wonder where to begin.

This session will introduce the core components in a breadth-first fashion focusing on the essentials. We will then build a simple Spring MVC-based webapp from scratch including implementation, testing, configuration, and deployment. Along the way you will see how to bootstrap a Spring-managed service layer, configure request handlers, render views, provide some validation logic, and even configure data-binding for a file-upload. We will round off the discussion with some best-practice guidelines and a quick "what next?" overview of some of the most important extension points.

Spring's Portlet MVC framework is one of the major new additions in Spring 2.0, bringing the proven benefits of the servlet-based Spring MVC framework to JSR-168 Portlet development.

In this presentation, you will learn how to use Portlet MVC to develop enterprise portlet applications. It will cover the framework's architecture and API in a direct comparison with Spring MVC. It will also include a walkthrough of a sample portlet application with a detailed review of the implementation and configuration. Mark will highlight a number of the framework's compelling features as well as its integration with Spring Web Flow.

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.
