by Alex Blewitt on  May 26, 2011 2

Yesterday, Mark Reinhold posted the first public draft of the future of modularity in Java. As it is a draft, there are a handful of issues that still need to be agreed on - but it represents the consensus of what modularity in Java should look like.

Annotation-Driven Dependency Injection with Google Guice 3.0

by Michael Floyd on  Apr 20, 2011 7

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).

by Alex Blewitt on  Apr 20, 2011

A new project on Google Code, the Pojo Service Registry, aims to provide an OSGi-lite mechanism for Java applications, but outside of a OSGi runtime. Instead of requiring all JARs to be bundles, it scans the startup classpath and emulates a bundle layer, whilst providing the service hookups that would be wired together in a full OSGi container.

Business Benefits of OSGi

by Alex Blewitt on  Nov 30, 2010 6

Many consider the cost of migration onto OSGi expensive, but frequently this is conflated with the cost of modularity itself. Modularising a large, complex and heavily intertwined library is an expense that has no immediate benefits to the maintainers. However, if left to rot, the system will become more complex, intertwined and larger over time and the maintenance cost will increase.

by Jean-Jacques Dubray on  Nov 11, 2010 13

Ross Mason, founder of MuleSource expressed his frustration with OSGi: "OSGi is a great specification for middleware vendors, but a terrible specification for the end user."
