Description

I sent this (accidentally) to axis-user list.
I received a response from Ane Thomas Manes indicating tht I should file this as a bug:

I am currently using Axis 1.2 beta to expose my web service.
I am using the document/literal (wrapped) configuration.

The axis server does something that seems strange, and I'm not sure if it's intentional or not. This email is not as long as it seems.

Given this operation (defined in my WSDL):

<operation name="getFactor">

<input name="getFactorRequest" message="impl:getFactorIn"/>

<output name="getFactorResponse" message="impl:getFactorOut"/>

</operation>

---------------------------------------------------------------------------------

The corresponding input and output messages are defined a follows:

<message name="getFactorIn">

<part name="parameters" element="intf:getFactor"/>

</message>

<message name="getFactorOut">

<part name="parameters" element="intf:getFactorResponse"/>

</message>

---------------------------------------------------------------------------------

The corresponding elements are defined as follows:
<element name="getFactor">

<complexType>

<sequence>

<element minOccurs="1" maxOccurs="1" name="id" type="xsd:string"/>

</sequence>

</complexType>

</element>

<element name="getFactorResponse">

<complexType>

<sequence>

<element name="factor" minOccurs="1" maxOccurs="1" type="intf:Factor"/>

</sequence>

</complexType>

</element>
---------------------------------------------------------------------------------

I won't bother providing the schema for the intf:Factor type.

Here's the question:
When a client calls the getFactor() method, why does the response always contain a top level element in the soap body call getFactorReturn instead of using the name provided in the getFactorResponse element schema: in this case "factor"?

So the response to this method looks like this (the top level element of the body tag is <getFactorReturn>):

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/ <http://schemas.xmlsoap.org/soap/envelope/> " xmlns:xsd="http://www.w3.org/2001/XMLSchema <http://www.w3.org/2001/XMLSchema> " xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance <http://www.w3.org/2001/XMLSchema-instance> "> <soapenv:Body>
<getFactorResponse xmlns="http://object.hydra.erisk.com <http://object.hydra.erisk.com/> ">
<getFactorReturn>
<name>My Test Factor</name>
<id>1</id>
</getFactorReturn>
</getFactorResponse>
</soapenv:Body>
</soapenv:Envelope>

I would have expected the response to this method to look like this (the top level element of the body tag is <factor>):

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/ <http://schemas.xmlsoap.org/soap/envelope/> " xmlns:xsd="http://www.w3.org/2001/XMLSchema <http://www.w3.org/2001/XMLSchema> " xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance <http://www.w3.org/2001/XMLSchema-instance> "> <soapenv:Body>
<getFactorResponse xmlns="http://object.hydra.erisk.com <http://object.hydra.erisk.com/> ">
<factor>
<name>My Test Factor</name>
<id>1</id>
</factor>
</getFactorResponse>
</soapenv:Body>
</soapenv:Envelope>

The reason this is an issue is that when you auto generate code (at least in .NET) using the WSDL I described above, it assumes (rightly so?) that the top level element of the response SOAP body will be named as you name it in your WSDL.

Please let me know if this is an issue with Axis or if there is a spec somewhere that requires the top level element to be named getFactorReturn (in this case).

Thank You,
