Aha -- because if the minOccurs attribute = 0, then Axis replaces the qname that
woulda been "xsd:int" (where xsd = http://www.w3.org/2001/XMLSchema) with
"soapenc:int" (where soapenc = http://schemas.xmlsoap.org/soap/encoding/). This all
takes place in org.apache.axis.wsdl.symbolTable#getNillableQName -- it appears that
the Axis developers are coupling the concept of nillable and minOccurs = 0 as per this
comment from the source:
// If we have a minoccurs="0"/maxoccurs="1", this is just
// like a nillable single value, so treat it as such.
I don't mean to drag everyone into this, but is that correct? If the thing *doesn't*
occur, I suppose it could be represented as xs:nil, but, seeing as how Axis is
generating this from WSDL that clearly states the type is of type "xsd:int" -- I don't
think the the toolkit should be making judgments as to whether or not it can swap
in/out namespaces. After all, the server side will most likely be expecting to see a
value from the xsd namespace.
The issue gets further muddied when you consider that the soapenc's
(http://schemas.xmlsoap.org/soap/encoding/.) representation of int is just a
restriction on xsd's int (http://www.w3.org/2001/XMLSchema).
I guess this is one of the reasons the ws-i people put their collective foot down.

Subject: why oh why - soapenc & minOccurs
All,
Does anyone have any input as to why, when given schema such as the
following:
<wsdl:types>
<xsd:schema targetNamespace="http://www.foo.com";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<xsd:element name="foo">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="bar"
type="xsd:int" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
<wsdl:types>
WSDL2Java generates code that indicates that bar is of type "int" as
defined in the "http://schemas.xmlsoap.org/soap/encoding/"; namespace? I
am bewildered. If I remove the minOccurs attribute, Axis will generate
the correct stub.
Sorry for a quasi-repost -- perhaps I didn't phrase my original issue
well or no one knew the answer ;).
Thanks,
Cory Wilkerson
