wsdl2as is a Java library and tool to generate ActionScript3 code implementing a client to webservice defined by a WSDL file.
A wsdl2as maven plugin exists to integrate this process into your Maven 2 build.
wsdl2as supports WSDL 1.1 definitions of document/literal SOAP services.
Wrapped-style services are supported, and wsdl2as will unwrap parameters and response values when it recognises the 'wrapped' pattern.
Some SOAP basics working, though the XML-Object mapping provided via asxsd still leaves a lot to be desired.
Don't use this project in a production environment yet, unless you are willing to get your hands dirty fixing any problems you find in the code.
