Sam/axis-dev,
Thanks Sam for providing the wire dumps. I have some questions...
So a runtime could send an array using "style A":
<name type="soapenc:Array" soapenc:arrayType="ns:foo[3]" >
....
Or a runtime could send an array using "style B":
<name type="ns:ArrayOfFoo" soapenc:arrayType="ns:foo[3]" >
....
Apache SOAP is sending "style B"; I believe it used to send "style A".
Apache Axis sends "style A".
------------------------------------------------------------------------------------------------
A compliant runtime can receive an array of type "style A".
In this case the deserializer is easily found because the type is
"soapenc:Array".
A compliant runtime can receive an array of type "style B".
In this case, the runtime will attempt to find a deserializer of type
"ns:ArrayOfFoo". In the case of Axis below, "ns:ArrayOfFoo" is not
registered in the deploy.wsdd for samples.echo.TestClient.
QUESTION 1: So should the behaviour be 1) fail as below or 2) if a
deserializer is not found
choose the array deserializer if the soapenc:arrayType attribute is
present?
My answer: I can make the change to implement (2) if I get some feedback
from axis-dev.
QUESTION 2: Since the runtime can easily choose which style to send, should
we lean
towards sending "style A" since it is more likely to be accepted by the
remote runtime?
My answer: We should send "style A"

The SOAP echoStructArray failed that night as I had updated the client but
not the server. Since then I had difficultly running Axis with the latest
Tomcat for a classloader/javax issue that I finally tracked down. My
feeling at the moment is that the wire dumps attached below are both (1)
consistent with the WSDL definition, and (2) able to be produced by an
appropriately configured Apache SOAP installation out in the field without
any code mods. The topic of what Axis should send is certainly up for
discussion, but in my mind it is clear that the following datastreams
should be accepted.
