<ul>
<li>Plugin architecture for startup/shutdown hooks and middleware components</li>
<li>Distributed OAuth2 JWT security verification as part of the framework</li>

<li>Audit to dump important info or entire request and response.</li>
<li>Body parser to support different content types</li>
<li>Standardized response code and messages from configuration file</li>
<li>Externalized configuration for all modules for dockerized environment</li>

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>

Blade is a pursuit of simple, efficient Web framework, so that Java web development even more powerful, both in performance and flexibility. The design is simple, easy to understand and doesn't introduce many layers between you and the standard library. The goal of this project is that the users should be able to understand the whole framework in a single day. It supports RESTful style routing interface. It has no invasive interceptors and provides the writing of DSL grammar.

RESTX is the lightweight, modular, feature rich, blazing fast, open source Java REST framework. It shares similarities with modern frameworks like Play! like hot compile and a very productive experience, but focused on REST and pure Java.
 
It is focused more on Rest. This implies that it’s not a general web framework, i.e., there is no templating mechanism. It’s better use with a JavaScript framework on the client side, and you can always use any other templating mechanism to serve your pages.

Griffon is desktop application development platform for the JVM. Inspired by Grails, Griffon leverages concepts like Convention over Configuration, modularity, and freedom of choice. The framework at its core is written 100% in Java allowing developers to write their own applications with only Java. Other programming languages such as Groovy and Kotlin may be used too, in which case additional capabilities such as builders and extension methods become available.
 
Griffon encourages the use of the MVC pattern. Griffon also follows in the spirit of the Swing Application Framework (JSR 296), it defines a simple yet powerful application life cycle and event publishing mechanism. Another interesting feature comes from the Groovy language itself: automatic property support and property binding (inspired by BeansBinding (JSR 295)), which makes creating observable beans and binding to their properties a snap! As if property binding was not enough Groovy’s SwingBuilder also simplifies building multi-threaded applications, say goodbye to the ugly gray rectangle (the bane of Swing apps)!

Xenon is a framework for writing small REST-based services. (Some people call them microservices.) The runtime is implemented in Java and acts as the host for the lightweight, asynchronous services. The programming model is language agnostic (does not rely on Java specific constructs) so implementations in other languages are encouraged. The services can run on a set of distributed nodes. Xenon provides replication, synchronization, ordering, and consistency for the state of the services. Because of the distributed nature of Xenon, the services scale well and are highly available.
 
Xenon is a "batteries included" framework. Unlike some frameworks that provide just consistent data replication or just a microservice framework, Xenon provides both. Xenon services have REST-based APIs and are backed by a consistent, replicated document store.
 
The lightweight runtime enables the creation of highly available and scalable applications in the form of cooperating light weight services. The operation model for a cluster of Xenon nodes is the same for both on premise, and service deployments.

Spincast is a framework to serve as a backend for Single Page Applications (SPA), to develop old-school HTML generated websites or to be a REST API services platform. Spincast aims to feel more like a library than like a framework. It is not opinionated and favors configuration over convention. Its main goal is to give power to the developers. 

Spincast is an highly flexible and open source Java web framework, based on Guice
