Apache's implementation of the JavaServer Faces (JSF) and Jakarta Faces specification

Branches

Main

Jakarta Faces 4.0 implementation
Based on the refactored 2.3-next codebase

3.0.x

Jakarta Faces 3.0 implementation
It's equals to JSF 2.3 but with “jakarta.faces” packages and constants instead of “javax.faces”

2.3-next

(Almost) JavaServer Faces 2.3 implementation
Completely refactored codebase compared to 2.3, also providing a Quarkus extension
2.3-next equals the JSF 2.3 API but delegates @ManagedBeans to CDI; ManagedBeans configured via XML are completely ignored. The implementation of the old FacesEL (javax.faces.el.*) also has been completely removed.

2.3.x

JavaServer Faces 2.3 implementation

Minimum Requirements (main / 2.3-next)

Java 1.8
Servlet 3.0
EL 2.2
CDI 1.2
JSTL 1.2 (optional)
BV 1.1 (optional)

Servlet 4.0 will enable JSF to serve resources via HTTP/2 push.

Installation

Quarkus extension

Since 2.3-next a Quarkus extension is available. A sample project can be found here: https://github.com/apache/myfaces/blob/main/extensions/quarkus/showcase/

Uber-JARs are not supported by design

Differences to a normal servlet container

You need to put your views under src/main/resources/META-INF/resources as Quarkus doesn't create a WAR and src/main/webapp is ignored!
Session replication / passivation / clustering is not supported yet by Quarkus
