So I found the answer to my question. When sending the data to XFire,
the namespaces must be set on the fields of the complex data type, as
below:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/
envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:ns4="http://rpc.whisper.ucsc.edu";
xmlns:ns5="http://core.whisper.ucsc.edu";
>
...
<ns4:addItemToLibrary>
<in0>
<ns5:authors>
<AuthorData>
<ns5:person>false</ns5:person>
<ns5:organizationName>test org</ns5:organizationName>
</AuthorData>
</ns5:authors>
<ns5:dateCreated></ns5:dateCreated>
<ns5:primaryKeyword>test2</ns5:primaryKeyword>
<ns5:title>test</ns5:title>
</in0>
Note the ns5: on the person and organizationName fields.
The only part that I'm left confused about though is why XFire
doesn't put (or maybe doesn't need to put) the namespaces on outgoing
messages, as below:
<getAllItemsInfoResponse xmlns="http://rpc.whisper.ucsc.edu";>

I'm a little bit confused, because you mixed System.out and log.
Could it be that the first element of the List returns null, it
fails with a NPE in author.isPerson() and we don't see the
System.out logs?
M.
Bloody hell. Thanks for catching that. I'm teaching a beginning
programming course this quarter (in Java), and spent all afternoon
yesterday telling students how to use System.out.println().
After fixing the logging statements, I'm finally able to see the
exception that's getting thrown. Its a NullPointerException within
the proxy for my Author object.

The method signature for isPerson() is:
public final boolean isPerson()
So that made me think that perhaps a value wasn't sent for that
field, but the SOAP message did send one (I've formatted this to
make it more readable):

The WSDL for the service is below.
So I tried changing the type from the Author interface to the
AuthorData implementation class, and added logging statements to
the constructors and property setters. With those changes, the
output I get is:

So you can see that the class is begin created, but the properties
aren't being set. I'd be willing to bet that this is the cause of
the NullPointerException when the dynamic proxy for the Author
interface is used instead of the concrete class. And it brings me
back to my question from last night: Is the AuthorData part of my
message formatted/layed out correctly, and if not, what should it
look like?
Thanks,
Mark
