Re: using GWT with flex?

What exactly  do you mean  with "incorporate ajax" ? 
Do you mean making async  call to the server ? 
If  yes cant you do that with Blase DS ?

Like i said before i dont know  if the road mxml/as ->External Interface -> js ->  gwt -> backend  and  back is effective
because  you are adding  a lot of overhead just to call methods in the backend.

Thanks for response. We are already using blazeds to communicate with our remote spring services. Our present architecture:
Flex talks to backend java objects using spring blazeds.

I want to incorporate ajax so What I had in mind is
Flex mxml/as screen invokes JavaScript invokes java backend?
Would that be correct?

Thanks

Well the suggestion  was for the "Integrating Flex with GWT part". 

If you come from Flex learning GWT should not  be a  big problem because the development model is very similar.
The official GWT Documentation is always a good point to start: http://code.google.com/webtoolkit/doc/latest/DevGuide.html
And if you are really really stucked there is a guy called Thomas Broyer here in the community. You cant miss him :)

Making a GWT RPC call from an AS3/MXML based  Flex application is not that easy and adds a lot of  overhead to your application.

We had the same issue with one of our Flex applications. This is one of the reasons that motivated me to create a GWT API for Flex, so one could use Java everywhere instead of mixing MXML/AS3(Flex UI), JavaScript(External Interface to communicate with the GWT ) and Java(GWT +  backend)

If your Flex application is MXML/AS3 based the best way should be to use something like Blase DS.

If you want to use a GWT API to build a Flex application  you can  have a look at gwt4air.

Best,

Alain

from flex background.
