Hi Jerry,
I am doin some R&D on flex intergration with J2EE. I ve some doubts.* How do I navigate from one mxml page to another.. feature similar to that of RequestDispatcher or do you any alternate approach.
Remember that the RequestDispatcher in the
Servlet API is tied to the request/response paradigm enforced on us by HTTP and
the page-request model of a website.
With RIA development, we can break free of
the shackles of request/response, to a pseudo-thick-client model.
Instead of thinking in pages, we think in terms of an application where our only
server round-trip is for RPC method invocation and the exchange of
data.
So ... rather than dispatch the request
forward to view another JSP, it's MUCH easier to simply have your RIA client
"render" another view state that already exists on the
client.
It's a bit of a head-warp, but once you get
your head around it, it's liberating, I assure you...
* Is there any framework kindoff for intergrating Flex with J2EE application.
Funny you should say that ... check
out:
With Cairngorm, we took what we consider
to be the appropriate patterns from the Core J2EE Pattern catalogue (Alur et al) and applied them to
Flex RIA development and Flex/J2EE integration. From the questions you're
asking, Cairngorm is going to be instantly familiar to you, and will get you
rapidly up to speed with organising and architecting a Flex
RIA.
When
you download Cairngorm, there's also a "Cairngorm Store" application, that will
be a good starting point for you for seeing how the framework is used in
anger.
Think mini-Struts for Flex RIA, and you're
there.
* What is the best practice to communicate with J2EE application like
should I opt for remoteobject or
httpService or webService.
For a J2EE application where you own the
server-side as well as the client, I'd go RemoteObject every single time,
from a performance standpoint, as well as from the stadndpoint of how little (ie
not at all) you need to impact your server-side development to accomodate
Flex.
It's pre-Flex, but I wrote a whitepaper for
Macromedia some time ago, to discuss Flash Remoting (AMF / RemoteObject) versus
WebService versus HTTPService - you can find it here:
I
think most of the arguments (if not all of them) still
stand.
* Any recommendation on good books for Flex intergration to J2EE.
Funny you should ask that
:-)
I'm one of the authors of "Developing Rich
Clients with Macromedia Flex", and there's a significant treatment of
integration with J2EE infrastructure. You can find out more at http://www.iterationtwo.com/flexbook/
There's a number of chapters of the book
available for free download.
For you, I'd recommend you start with the
chapter on "Flex and J2EE Integration" which was made available some time ago at
theserverside:
Three
other chapters are available at macromedia.com:
I think that's MORE than
enough resource to get you started. If you have any further questions on
Flex/J2EE integration, or on the Cairngorm microarchitecture for RIA
development, please don't hesitate to ask.
It's a leap of faith from
a previous life of abusing stateless HTTP protocols to produce anaemic and
ineffective user experiences, to the brave new world of developing richer, more
immersive and effective RIA user experiences with Flex.
Welcome to the other
side.
