When applications grow bigger, modularity becomes a key aspect regarding maintainability. Design decisions made in the early days are hardly discoverable in the codebase, inter-module dependencies grow a lot. The talk introduces means and approaches to connect logical architecture to the codebase.

One of the questions we get asked the most by developers and architects is: when and why would I use OAuth2? The answer, as often with such questions, is “it depends”, but there are some features of OAuth2 that make it compelling in some situations, especially in systems composed of many lightweight web services, which becoming a very common architectural pattern.

Deploying modern applications in the cloud can introduce new challenges like distributing and integrating application components across private and public networks, using heterogeneous messaging systems, driving heavier workloads and horizontally scaling the messaging tier. Learn how to overcome these challenges using proven enterprise integration patterns with AMQP based messaging, Spring Integration and RabbitMQ.

This video explores the dependency injection options available to developers using Scala. It covers several options including Java frameworks like Spring and Guice, and Scala language approaches such as the Cake pattern.

An introduction to the SpringSource Tool Suite Error Analysis. SpringSource Tool Suite (STS) provides the best and most complete set of Eclipse-based tools for building Spring-powered applications that run on the major application server platforms, including Apache Tomcat, SpringSource tc Server, SpringSource dm Server, IBM WebSphere, Oracle WebLogic, and JBoss. STS incorporates a task-focused user interface to speed development, architecture review tools to guide developers toward best practices and runtime error analysis with automated resolution lookup to help developers solve problems in running applications.

Spring ActionScript is an offshoot of Java Spring and brings Inversion of Control to the Flash Platform. Primarily focusing on Flex and AIR development, you’ll learn how this framework can be used to build testable and maintainable applications. We’ll take a look at the different kinds of configuration options, how it compares to Java Spring and what building blocks it includes to create tailored architectures.

Spring Roo is an exciting new rapid application development framework. It slices and dices and packs all the punches of frameworks like Rails and Grails but the end result is pure Java. In this presentation, we will be discussing what Spring Roo is and demonstrate it’s how it can be used to trim your development time and make your code more readable.

This video introduces the OpenSource library Hades that significantly eases implementing data access layers with JPA. It takes the audience on a guided tour through code samples introducing the features of Hades:
* Executing queries by only declaring interface methods
* Extending the EntityManager to provide a typed interface, programmatic pagination and sort support
* Combining execution of finder methods with pagination
* Auditing of entities to keep track of creation and modification date and user
* Integration of custom data access code
* Integration into Spring applications via Spring namespace and Spring IDE extension

Beside doing an overview of the Grails framework, Jeff Brown shows how to write a Spring-integrated application in Grails. Some of the topics covered are: Spring Beans in Groovy, DI in Grails, Grails and Spring MVC, Database transaction management and remoting with Spring in Grails.
