SEAM and JavaServerFaces

I would like to formally announce that JAVAWUG (Java Web User Group) is holding the Thirty Sixth Birds-of-Feather (Meet-up 36) at Sun CBC on Wednesday, 16th April 2008 from 18:45 until 20:15. Talk
Seam is an open source "deep integration" framework that tries to have the best of both the Java EE and Spring worlds. Seam is firmly rooted in Java EE standards. It started out to address the design flaws between two key Java EE frameworks: JSF and EJB3. Some of its core features are being adopted in future official Java EE standards such as JSF 2.0 and WebBeans. As more and more users start to adopt Seam, it has expanded far beyond the scope of Java EE.

This talk will start with a brief on Java Server Faces, EJB 3.0, AJAX, Remoting then an introduction on Seam,

- What is Seam, The contextual component model, State management, ...

- What advantage you have by using Seam in your project.

- It's time to deprecate the Stateless Web Application !!

WebBeans (JSR 299) :

EJB 3.0 :
Facelets : Attendee should have a basic knowledge of Java Web Development (JSP, JSF, Struts, ..) and also a general understanding of Java EE5.

Biography Sebastien Degardin is a Java EE developer involved in the JBoss Seam community.
Having experience in Java SE and Java EE (mainly Java EE 5 and EJB3)).
He currently trying to become specialist in transactional system (JTA and others).
Sebastien used to live in Brussels, San Francisco, now involved in projects in London.

    New technologies for me but interesting to get an insight in its capabilities.

    It was great to meet you all last night, I hope everyone enjoyed the talk and the drinks afterwards. I would be keen to hear any feedback on last night.

    The talk was great, and I thought what made it more special was the excellent job that Barry and his company did by supporting the meet up group through out

    The meeting was great, with a very good technical presentation which gave me a very good idea of what SEAM is capable of and how powerful it is. We had quite a lot of good questions and concrete answers for them. I would like to thank the JAVAWUG guys for the organization and promotion of the event, Barry Cranford for the drinks and for the great night and mainly Sebastien Degardin for the great presentation. Besides that, it was a great opportunity to meet other java developers.

    JSF is becoming more and more popular but still has some problems. SEAM comes to solve many of them.
    Among all cool features that SEAM has, I will highlight a few of them:
    - Integrate JSF with EJB 3.0.
    - Declarative state management: Seam extends the context model defined by the servlet spec?request, session, application?with two new contexts?conversation and business process?that are more meaningful from the point of view of the business logic.
    - Bijection: Differs from IoC in that it is dynamic, contextual, and bidirectional. You can think of it as a mechanism for aliasing contextual variables (names in the various contexts bound to the current thread) to attributes of the component. Bijection allows auto-assembly of stateful components by the container. It even allows a component to safely and easily manipulate the value of a context variable, just by assigning it to an attribute of the component.
    - Workspace management and multi-window browsing.
    - Prefer annotations to XML.

    Seam has the same possibilities as JSF, however the configuration seems to be way simplier and much more efective.

    Very interesting technical presentation and demonstration of Seam's features as well as an introduction to JSF and EJB3 which was much appreciated by me.

    I've been using JSF for almost 2 years now but I still didn't find the necessity to use SEAM. In a certain way, I find some of the ideas behind SEAM a bit controversial, mainly when it comes to expose your domain model to the view layer. I'm very keen to go to this presentation and maybe clarify a few points. I looked at SEAM quite a while ago and I'm looking forward to see the improvements.
