I'm using Axis2 to generate a client from WSDL. I'm having a problem with the databinding. The WSDL I'm using is somewhat complex, so to illustrate the problem I created some simpler WSDL. Consider this fictitious service that takes as a request a last name, and then returns as a response the husband (first name, last name) and wife (first name, last name, maiden name) registered with that last name.
Here are how the types are defined in the WSDL:
<xsd:schema targetNamespace="http://www.example.org/family2/">
<xsd:element name="FamilyLookupRequest">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="lastName" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element name="FamilyLookupResponse">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="husband">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="firstName" type="xsd:string" />
<xsd:element name="lastName" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element name="wife">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="firstName" type="xsd:string" />
<xsd:element name="lastName" type="xsd:string" />
<xsd:element name="maidenName" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
In Axis2 it doesn't handle this correctly. The FamilyLookupRequest object is created correctly. But because the FamilyLookupResponse has nested complex types Axis2 does not create the FamilyLookupResponse class correctly. Axis2 creates the husband_type0 and wife_type1 classes correctly. The FamilyLookupResponse class contains a husband and wife member, but they are defined as OMElements instead of their correct type (husband_type1, and wife_type0).
If I change the WSDL as follows, Axis2 will then create the classes correctly. Any ideas? Is this a bug?
<xsd:schema targetNamespace="http://www.example.org/family2/">
<xsd:complexType name="husband">
<xsd:sequence>
<xsd:element name="firstName" type="xsd:string" />
<xsd:element name="lastName" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="wife">
<xsd:sequence>
<xsd:element name="firstName" type="xsd:string" />
<xsd:element name="lastName" type="xsd:string" />
<xsd:element name="maidenName" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
<xsd:element name="FamilyLookupRequest">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="lastName" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element name="FamilyLookupResponse">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="husband" type="fml:husband" />
<xsd:element name="wife" type="fml:wife" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
Lastly Axis 1.4 handles either version of the WSDL correctly.
