Hi,
I'm having a problem where Axis C++ is generating stub code
that does not compile. After trimming the WSDL file down a bit,
I've narrowed it down to the case where a complexType has
a field which is an array of xsd types, e.g.,
<xsd:complexType name="myComplexType">
<xsd:all>
<xsd:element name="data" type="typens:ArrayOfInt"/>
</xsd:all>
</xsd:complexType>
<xsd:complexType name="ArrayOfInt">
<xsd:complexContent>
<xsd:restriction base="soapenc:Array">
<xsd:attribute ref="soapenc:arrayType"
wsdl:arrayType="xsd:int[]"/>
</xsd:restriction>
</xsd:complexContent>
</xsd:complexType>
Here is an example WSDL file including the above:
<?xml version="1.0"?>
<definitions name="MyService" targetNamespace="urn:typens"
xmlns="http://schemas.xmlsoap.org/wsdl/";
xmlns:typens="urn:typens"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/";
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<types>
<xsd:schema xmlns="http://www.w3.org/2001/XMLSchema";
targetNamespace="urn:typens">
<xsd:complexType name="myComplexType">
<xsd:all>
<xsd:element name="data" type="typens:ArrayOfInt"/>
</xsd:all>
</xsd:complexType>
<xsd:complexType name="ArrayOfInt">
<xsd:complexContent>
<xsd:restriction base="soapenc:Array">
<xsd:attribute ref="soapenc:arrayType"
wsdl:arrayType="xsd:int[]"/>
</xsd:restriction>
</xsd:complexContent>
</xsd:complexType>
</xsd:schema>
</types>
<message name="myMethodRequest">
<part name="mydata" type="typens:myComplexType"/>
</message>
<message name="myMethodResponse">
<part name="mydata" type="typens:myComplexType"/>
</message>
<portType name="MyServicePort">
<operation name="myMethod">
<input message="typens:myMethodRequest"/>
<output message="typens:myMethodResponse"/>
</operation>
</portType>
<binding name="MyServiceBinding" type="typens:MyServicePort">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<operation name="myMethod">
<soap:operation soapAction="urn:typensAction"/>
<input>
<soap:body use="encoded" namespace="urn:typens"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
</input>
<output>
<soap:body use="encoded" namespace="urn:typens"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
</output>
</operation>
</binding>
<service name="MyServiceService">
<port name="MyServicePort" binding="typens:MyServiceBinding">
<soap:address location="http://127.0.0.1/soap"/>
</port>
</service>
</definitions>
The stubs are generated without any errors:
# java org.apache.axis.wsdl.wsdl2ws.WSDL2Ws -ostubs -lc++ -sclient example.wsdl
log4j:WARN No appenders could be found for logger
(org.apache.axis.i18n.ProjectResourceBundle).
log4j:WARN Please initialize the log4j system properly.
Code generation completed.
However, when I try to compile this, I get the following:

If the array elements in ArrayOfInt are instead wrapped to use
a complex type that just wraps an individual xsd type, the
generated code compiles. This is one possible workaround I
suppose. Nevertheless, this seems like it is potentially a bug.
