Loom is a micro-kernel designed and implemented on top of the DNA framework. It supports components developed using the Avalon framework. In the future Loom will also support DNA and Pico components.

NanoContainer is a Dependency Injection (DI) container that manages trees of PicoContainers. NanoContainer adds the following features to PicoContainer:
HiveMind is a services and configuration microkernel:
Services: HiveMind services are POJOs (Plain Old Java Objects) that can be easily accessed and combined. Each service defines a Java interface it implements. HiveMind takes care of instantiating and configuring each service just as necessary. HiveMind lets services collaborate with each other via dependency injection.
Configuration: HiveMind allows you to provide complex configuration data to your services in a format you define. HiveMind will integrate the contributions of such data from multiple modules and convert it all into data objects for you. HiveMind configurations allow for powerful, data-driven solutions which combine seemlessly with the service architecture.
Microkernel: HiveMind is a framework for creating applications, not an application, or even an application server, itself. The 'core' of HiveMind is the startup logic that knows how to parse and understand the module deployment descriptors, and use that information to instantiate and initialize all those services and configurations.
In HiveMind, a service is an implementation of a Java interface. Unlike other SOAs (Service Oriented Architectures, such as a SOAP, or EJBs), HiveMind is explicitly about combining Java code within a single JVM. HiveMind uses a descriptor to describe different services, their lifecycles, and how they are combined. HiveMind takes care of thread-safe, just-in-time creation of singleton service objects so your code doesn't have to.
Excalibur is an open source software project of The Apache Software Foundation that contains a lightweight, embeddable Inversion of Control container named Fortress that is written in java.
Guice is a dependency injection container that wholly embraces annotations and generics, thereby enabling you to wire together and test objects with less effort than ever before. Annotations finally free you from error-prone, refactoring-adverse string identifiers.
