Spring is an Application framework which has Inversion of Control container, Aspect-oriented programming framework, Data access, Transaction management, Model-view-controller for web, Remote access framework (RPC) and lot more. It is well integrated with Toplink, Hibernate, JDO, and iBATIS. Spring Social is an extension of the Spring Framework that enables applications to connect with Software-as-a-Service (SaaS) providers such as Facebook and Twitter and interact with those services on behalf of their users.

Spring - Application Framework

A CQRS (Command Query Responsibility Segregation) Framework for Scalable, High-Performance Java Applications. 
Axon decouples application components to enable linear dynamic scaling. Logical components are separated within your architecture in a service oriented manner, and coupled using an asynchronous message bus. This enables components to be physically spread amongst different servers and hereby realizing linear scaling.
 
Axon Framework helps build scalable, extensible and maintainable applications by supporting developers apply the Command Query Responsibility Segregation (CQRS) architectural pattern. It does so by providing implementations of the most important building blocks, such as aggregates, repositories and event buses (the dispatching mechanism for events). Furthermore, Axon provides annotation support, which allows you to build aggregates and event listeners without tying your code to Axon specific logic. This allows you to focus on your business logic, instead of the plumbing, and helps you to make your code easier to test in isolation.
 
Axon does not, in any way, try to hide the CQRS architecture or any of its components from developers. Therefore, depending on team size, it is still advisable to have one or more developers with a thorough understanding of CQRS on each team. However, Axon does help when it comes to guaranteeing delivering events to the right event listeners and processing them concurrently and in the correct order. These multi-threading concerns are typically hard to deal with, leading to hard-to-trace bugs and sometimes complete application failure. When you have a tight deadline, you probably don’t even want to care about these concerns. Axon’s code is thoroughly tested to prevent these types of bugs.

AxonFramework - High Performance and Scalability framework for Java

MyFaces is a family of projects related to the JavaServer Faces (JSF) specification published as part of the Java Community Process. The "core" project is an implementation of that specification. Other MyFaces projects implement related specifications (eg the Portlet Bridge), or add features to any JSF implementation (not just the Myfaces Core). JavaServer(tm) Faces (JSF) is a web application framework specification (JSR252, JSR127) based around the model-view-controller pattern. The Apache MyFaces project provides both an implementation of the JSF specification ("MyFaces Core"), and a set of add-on libraries that work on any implementation of the specification (including, of course, Apache MyFaces Core). JSF is quite similar to the <a class="http" href="http://jakarta.apache.org/tapestry">Tapestry framework</a> as that is also a component-based framework. JSF can also fill the same "niche" as the well-known <a class="http" href="http://jakarta.apache.org/struts/">Struts framework</a>, but has a rather different approach.

 The Apache MyFaces project provides: 
 <UL>
	<LI>A JavaServer(tm) Faces implementation (MyFaces API, MyFaces Impl modules)</LI>
	<LI>Several component libraries containing UI widgets for building web-applications with JSF (e.g. MyFaces Tomahawk, MyFaces Trinidad, MyFaces Tobago)</LI>
	<LI>Extension packages to JavaServer(tm) Faces (e.g. MyFaces Orchestra, MyFaces Extensions Validator)</LI>
	<LI>integration modules to other technologies and standards (e.g. MyFaces Portlet Bridge for integration with the portlet-standard)</LI>
