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

Branches

main

Jakarta Faces 5.0 implementation

4.1.x

4.1.x Jakarta Faces 4.1 implementation

4.0.x

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

2.3-next

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

2.3 JavaServer Faces 2.3 implementation

Minimum Requirements (main)

  • Java 17+
  • Servlet 5.0+
  • EL 5.0+
  • CDI 4.0+
  • JSTL 3.0+ (optional)
  • BV 3.0+ (optional)

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/

Not supported features:

  • Quarkus Uber-JARs are not supported (See: https://issues.apache.org/jira/browse/MYFACES-4427)
  • Quarkus does not support session replication / passivation / clustering
  • Quarkus beans are not serializable and therefore session passivation would never work anyway
  • Quarkus does not implement @ConversationScoped
  • Quarkus does not support injection in normal objects, therefore injection in JSF artifacts like NavigationHandler etc. is not supported

Differences to a normal servlet container while developing

  • 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!
