E-commerce with FLEX. Good Idea?

Hi. I'm gonna develop an e-commerce but I'm having problem deciding what kind of technology to use. I'd like to use flex + Java, but I never saw an e-commerce built and working over flex. What do you think?

Thanks.

There are plenty out there.

Things I would caution you with for large Flex based sites ("e-commerce" or otherwise):

For complex forms its not the best choice (you will find yourself reinventing the wheel a bit). Flash is best with lots of graphical interactive stuff, not things that are largely text and inputs.

performance testing is more complex than an HTML site

i18n support is in its infancy (its fine for Western character sets, but less good for RTL languages)

E-commerce require a quick response time or the customer goes elsewhere. A carelessly build fat client and you loose your customers

Container integration is poor with BlazeDS (should you use this). If you want to use a JEE container other than Tomcat/JBoss, things will go wrong.

Right, Paul. But what languages/frameworks would you use to develop the client side? HTML/CSS, JQuery, Servlets/JSP, Wicket, Tiles, Velocity? What kind of technologies websites like amazon.com has been used? The server side is easy to me because I've worked with java for years. And maybe it's the problem. I'm a java programmer and I have dificult do make a rich client side. That's why I'm trying to use a good RIA.

Can't speak for Amazon really, but ultimately their site appears to be is just HTML plus some AJAX. What frameworks they use I can't say.

I think you are clouding the question. Its really:

Some plug-in technology (such as Flash, Applets, native ActiveX application)

or HTML (with AJAX/JavaScript frameworks if required)

The server side is easy to me because I've worked with java for years

We'll that's OK, except Flex presents you with a bunch of new problems for which you usually need something like BlazeDS or LCDS.

I developed some webapps with flex/blazeDS. It was a good experience. But I think it's not (maybe yet) a good idea to develop wesites.
OK, Paul. My choice is HTML/AJAX.

Thanks a lot.
