This is a well know bugs of POST method of Flash's XML Api, post method
is not interpreted by some Servlet contatiners, for example Orion/Oracle
OC4J.
You has to process directly the input stream of http request.
I attached an example of XSP which process the XML input stream, this
example could help you as jump start to solve your problem.
If it doesn't work I'll sent to you other JSP tomorrow.
Best regards, Marcelo.
