shpelda commented on AXIS2-3891:
--------------------------------
Have the same issue, following type definition gives mentioned error:
<xsd:element name="scr-response">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="header" type="xsd:string"/>
<xsd:choice>
<xsd:element name="data" type="xsd:string"/>
<xsd:element name="error" type="xsd:string"/>
</xsd:choice>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
workaround would be to change it in following manner:
<xsd:element name="scr-response">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="header" type="xsd:string"/>
<xsd:element name="body" type="response-body-type" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="response-body-type">
<xsd:choice>
<xsd:element name="data" type="xsd:string"/>
<xsd:element name="error" type="xsd:string"/>
</xsd:choice>
</xsd:complexType>
This is happening only if generating serverside bindigs.

> The WSDL is confidential as also the specific schemata. Security annotations
> were made to an existing WSDL along the lines of the example given by the
> Rampart tutorial at:
> http://wso2.org/library/3190 and this WSDL:
> http://wso2.org/files/UToverHTTPS.xml
> Public XSDs can be retrieved from here:
> http://www.iso20022.org/catalogue_of_unifi_messages.page
> Does anybody have a hint why unwrapping fails? Are XSD choice elements not
> supported in combination with multiple XSDs?
