After some time, I'm back again at my problem trying to directly
returning XML from a web service. With RPC/encoded I'd get "section 5"
encoding, but that's not what I want.
I'd like to return XML like this in the SOAP response
<root>
<child>CHILDVALUE</child>
<list>
<item>ITEM1</item>
<item>ITEM2</item>
</list>
</root>
I've set up a test project where the serializer fakes this for a dummy
return value. With rpc/encoded this works partly, that is, I can call
the web service from a browser and get the result I want. But, of
course, the result isn't really rpc/encoded, it actually is document
(or wrapped)/literal. Now, when I change deploy.wsdd to reflect this
(see below), my serializer isn't found anymore, as the thrown exception
indicates
java.io.IOException: No serializer found for class
wsdltest.MyReturnValue in registry

at
org.apache.axis.encoding.SerializationContext.serializeActual(SerializationContext.java:1267)
at
org.apache.axis.encoding.SerializationContext.serialize(SerializationContext.java:778)
...
Further problems are creation of appropriate WSDL, deserialization, and
generation of client code.
I've looked through the axis samples and searched on the web, but I was
unable to find an example that demonstrates what I'm trying to do. I'm
wondering whether it's really so utterly uncommon.
