History JSF 2.3 New Feature Review Opening Up Java EE Summary Q&A 2
This talk assumes basic familiarity with JSF. JSF has lots of flashy components and wonderful ways to work with it. There are other resources to visit for that perspective on JSF. This talk has a little historical content in the front, some opinion on JSF relevance in a contemporary context. The heart of the talk is the feature review, entirely in NetBeans, some words about opening up JavaEE and I intend to leave 5 – 10 minutes time for Q&A, even with our short 45 minute session duration. 3 4 5

8. How Can JSF Still Be Relevant?
Abstractions Endure
WE STILL NEED WEB APPS THAT ARE QUICK TO BUILD,MAINTAINABLE, LOCALIZABLE, ACCESSIBLE, SECURE, DEVICE INDEPENDENT, Good looking, and are FUN TO USE

13. How can JSF Still Be Relevant?
Conversation with PrimeFaces Founder Cagatay Civici
JSF is still being used in back office applications
Government Agencies
Banks
Like to keep their business logic on the server side
Where applications are composed of lots of “screens”
Authored by many different people/teams
Share common template
It is “good enough” and many people already know how to use it.
It’s a “known quantity”, easy to find people to be productive with it.
How are people using JSF and PrimeFaces?
JSF is being used at back office applications.
Where a lot of "screens" are being used?
Government agencies, banks, people like the security aspect of it. Like
to keep their business logic at the server side.
OminFaces + PrimeFaces
Modernized with themes, using Resource Library Contracts from JSF 2.2:
Material Design.
The sticky-ness of the UI: the fact that it is good enough, and people
already know how to use it.
The way people use JSF has not changed a lot over the years. It's easy
to find programmers that can be productive with it. Easier learning curve.
Server Push
- Just like in Ajax: first not standard, now standard. At first glance
people just use pull, but at some point they find they need pull.
o:socket. Sending system messages to online users from admin console.
When the user does something, other users get notified.
Ajax Method Invocation
- Demanded in the spec for years. People use it when you need to do an
ajax call that is not related to the ui. When the UI elements reach a
certain combination, they would use ajax method invocation.
Multi-field validation
- They had been using workarounds first. Such as using action
listeners. Now they don't need to do this.
Tighter CDI integration
- Typesafety.
Component Search Expressions
- Because JSF was so heavily based on IDs, we needed some way to reach
into components, to manipulate.
People are using plain vanilla with HTML 5 friendly markup.
