I am trying to communicate with a Java webservice implemented using Apache
Axis. It has been working fine, until I tried sending an object with an
array property. When I call the webservice passing the array, I get the
following error:
org.xml.sax.SAXParseException: Element "xmlns:soapenc"cannot have "xmlns" as
its prefix.
I checked to make sure it wasn't an array.length = 1 issue... now I'm just
stumped. On the surface, it looks like Flex is not generating a valid SOAP
call to the webservice.
Below I have provided the Flex & Java code for a simplified example of the
problem. The code has 2 buttons: 'Get Foo' which calls the webservice to
get a Foo object, and a 'Save Foo', which simply passes that Foo instance
back to the webservice. It blows up when you click 'Save Foo'.
I also have captured the SOAP traffic between client & server.
Any help would be appreciated.
Thanks in advance,
-Tim.
