Thanks a lot for your reply. I recompiled the swf again &
in the Tomcat console I could see that the method on my class
was being called. So, thing that made this whole thing work
was,
Matt's advice to change the endpoint URI to
http://localhost:8080/flex/messagebroker/amf
&
recompilation of the swf after it.
However on the browser side I am seeing this error in a new window,
An ActionScript error has occurred,
TypeError: Error #1009: null has no properties.
at SimpleRemoteObject/::getNameHandler()
at SimpleRemoteObject/___Operation1_result()
at flash.events::EventDispatcher/dispatchEvent()
at
mx.rpc::AbstractOperation/http://www.adobe.com/2006/flex/mx/internal::dispatchRpcEvent()
at
mx.rpc::AbstractInvoker/http://www.adobe.com/2006/flex/mx/internal::resultHandler()
at flash.events::EventDispatcher/dispatchEvent()
at mx.rpc::Producer/acknowledge()
at
::NetConnectionMessageResponder/NetConnectionChannel.as$36:NetConnectionMessageResponder::handleResult()
at mx.messaging::MessageResponder/result()
Any clues ?
Thanks,
Aejaz
