ajax phase listener

[John Slave <sl...@libero.it>]

In bpcatalog tutorial there is a special requirement:
putting some xml in faces-config.xml to tell jsf servlet to use a 
special phase listener to manage request.
Why is not this requirement present in myfaces ajax component (for 
example input suggest). How can i easily create an ajax custom component 
using myfaces?

Yours faithfully

I preffer, use and recommend to use simple servlets to response the request
ajax.
Because PhaseListeners always will be invocated.

Something has to answer on the server if you do ajax, since there are as
for now no jsf mechanisms, you have to do it either via a jsp, a servlet
or a phase listener.
The phase listener approach is the one which is the least intrusive for
the end user, because it is sort of plug and play.

Sun chose this approach, others choose to use servlets for answering.

Check out the sources,  I normally do not push people towards the
sources, but in this case you have to. There are various easy components
which utilize ajax one way or the other in the sandbox.
The newer ones use dojo to reduce the amount of code on the javascript side.

You should note that in the more recent versions of these components (and
the way they are packaged with Java Studio Creator) this configuration file
is inside the component jar.  They do use a phase listener, courtesy of
Shale Remoting -- it is shared across all of the components using this
library, versus the early bpcatalog strategy of each component providing
their own listener.

Some people prefer to use separate servlets.  But zero configuration
(nothing needs to be added to web.xml) is a pretty nice feature of using a
phase listener.
