Has anyone had luck with embedded complex types with Axis. Taking the Address example one step further, I have WSDL describes an address to have a phone that is a complex type, such as:
<EmployeeVO> <firstName>John</firstName> <lastName>Doe</lastName> <phone> <area>999</area> <location>9999</location> <prefix>999</prefix> </phone> </EmployeeVO>
The WSDL, SOAP request, SOAP response and Java code follow. Basically, AXIS cannot serialize the response because it interprets "EmployeeVO" as containing "area"...
