Hi , Thanks alot for the help, I have made some modification and it is working now , i ll post the full mxml file later for the sharing Thanking all of you ..
RE: [flexcoders] Re: how to call dynamic servlet
Why are you converting the e4x XML into the legacy XMLDocument? And if you
really are satisfied working with dynamic Object instead of XML, then use
resultFormat=object and skip all that decdoing stuff. Flex will do that
for you. But that is the worst of both worlds; you lose the power of e4x
and suffer the diminished access performance of a dynamic object.
I suggest you use XML and XMLListCollection instead.

Hi Thanks alot for your reply,
I have removed the binding variables, replaced xml by e4x , and setted the
url before the service.send but am still unable to get the successful result
here is my modified code
