Hi all,
I have not implemented an application using JSF and was wondering the performance issues associated with it. One reads about it quite often, especially when comparisons are made, but it would be good to get some concrete answers from someone who has a system in production using JSF.
Any JSF pitfalls? Maybe the author can throw more light on this also.
Thanks,
Anuj

There's at least one more open source implementation and you'll soon see many commercial implementations from application server vendors.

So far, JSF seems not being popular, although it may get famous soon or later.
I guess large vendors, like IBM, SUN, BEA, will soon provide JSF plug-ins for JSF, however, by now, any tools and plug-ins that I can use together with WSAD?

have a nice one

JSF is a specification and the performance depends on a specific implementation of the specification.
I've seen reports about a flawed synchronization approach for the reference implementation that can cause performance problems, but there are other implementations. One I hear a lot of good things about is MyFaces: http://sourceforge.net/projects/myfaces/.

Just another question, what implementation do you base your book on?

Based on all the JSF articles, questions in Sun's JSF forum, JSF books about to be released, and the number JSF BOFs and sessions at this year's JavaOne, I say JSF seems to be very popular.
All the vendors you mentioned have tools in the works, for instance Sun's Java Studio Creator and Oracle's JDeveloper. I believe early access versions with JSF support is available for both products.
Keep in mind that the JSF 1.0 spec was released in March, roughly 3 months ago, and JSF 1.1 was released last week to fix a few problems. It always takes a few months for the vendors to get their products tested and released. And it takes even longer before major companies start using a new technology, so just be patient.
this is supposed to be a surprise, but it smells like a tiny ad:
