Hi,

I recently attempted to write a client for HP Service Center using CXF
2.1.4, and HPSC would not accept the message (it wouldn't tell us why
either, it just decided the message was invalid).  I then generated
stubs using Axis and went through the same procedure, but Axis wouldn't
send the message because I was not setting an attribute.  It threw an
exception and forced me to set it, even though the resulting XML (in the
message) just had the following placed into the message:

<keys /> 

I've included the relevant part of the WSDL below:

<xs:complexType name="ChangeModelType">
  <xs:sequence>
    <xs:element name="keys" type="ChangeKeysType"/>
    ..

Without setting the keys attribute on ChangeModelType, Apache says:

java.io.IOException: Non nillable element 'keys' is null.
        at
org.apache.axis.encoding.ser.BeanSerializer.serialize(BeanSerializer.jav
a:215)

Why doesn't CXF exhibit the same behaviour?

Thanks,


John
