JSON and Java through BlazeDS


Level 1
I'm using a regular httprequest to make call to a Java app
service that returns JSON. Can I make that same call using BlazeDS
and AMF? I'm having problems with Flexsessions when mixing the two
and want to just keep all my service calls in remoting.

I don't have much problems between flex sessions and sessions
in a JSP (if that is what you mean).

I would suggest to investigate some time using Blaze-DS
because it will give you a must faster response time then using

What is your exact problem using sessions??

Here is a example what I do :

set user_id in a session

FlexContext.getFlexSession().setAttribute("user_id", id);

get it back:

id =

get it in a JSP page:

user_id = session.getAttribute("user_id");

Thanks for the reply. Well problem is that I am making some
calls to my AMF service first and that sets a session cookie in the
broswer. Then when I use the Java service over HTTP, that service
sets another session cookie and my app gets confused. To fix it, I
have to delete the session cookie after my AMFcalls return which is
a bad hack. I tried making my Java calls over an http proxy but I
keep getting a "NetConnection.Call.BadVersion" error
