There is a constant tussle between following Agile techniques and still managing to do enterprise architecture. While Agile development focuses on adjusting the design as more insight is gained, architecture establishes the technology stack and addresses quality attributes.

Late last month Google released Guice 3.0, a Java framework that implements the dependency injection (DI) design pattern. The motivation behind Guice was to make it easier for programmers to write DI code by reducing the need to write boilerplate factories. This article examines the new 3.0 features, loks at how Guice 3.0 supports Spring DI, and introduces Guice 4.1 (a.k.a. MiniGuice).
The OOP conference (Object Oriented Programming) was held in Munich, Germany, from 24th to 28th January 2011 with “Business Impact through Mastering Change” as its general motto.

Sonatype, the professional services company that sponsors the development of many key Maven committers, has announced that they will build Maven 3 atop the Guice Dependency Injection (DI) container instead of the Plexus DI container employed for Maven 1 and 2. Backwards compatability will be ensured using a shim to support Plexus.
Dependency Injection has become a much more accepted and accessible approach in recent years, driven by many factors including increased popularity in SOA, TDD, and many other factors. With this has come increased usage of Dependency Injection frameworks. Bob Martin advises, with examples, applying a decoupling approach between your application code and your Dependency Injection framework.
Dependency Injection is one of the main features of recently released Java EE 6 version. JSR 330 (Dependency Injection for Java) provides a standardized and extensible API for dependency injection. And JSR 299 (Contexts and Dependency Injection for the Java EE Platform 1.0), which builds on JSR 330, unifies and simplifies the EJB and JSF programming models.
