Trouble with namespaces in a SOAP message generated with Axis2

Hello,

I am generating SOAP messages using Axis2 and a WSDL which you can find hereafter.
I logged the messages that are sent and I noticed a behavior that I cannot decide if it is legitimate or not (due to my lack of experience on SOAP I presume).
The first element in the content of the SOAP body is prefixed with a namespace which is defined in the WSDL while the definition of the element is described in a separate XSD file (that I import into the WSDL). I.e., in the sample SOAP message hereafter, I expected to see ns2 instead of ns3 as a prefix for element msg1.
Moreover, if I change the element prefix with ns2, I can validate the content of the message with eclipse while I cannot with the message as sent by Axis2.

Can someone explain this behavior ? What could be the problem if there is any ?

Thanks,

-          Emmanuel



The SOAP message :
<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
                <soapenv:Body>
                               <ns3:msg1 xmlns:ns3="wsdl-namespace" xmlns="xsd2-namespace" xmlns:ns2="xsd1-namespace<http://libra.intrinsec.com/bel_protocol/1.0/>">
                                               <ns2:metadata>
                                                               <ns2:id>322221</ns2:id>
                                               </ns2:metadata>
                               </ns3:msg1>
                </soapenv:Body>
</soapenv:Envelope>

The (relevant part of the) WSDL :
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<wsdl:definitions
                xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
                xmlns:tns="wsdl-namespace"
                xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
                xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                xmlns:xsd1="xsd1-namespace"
                xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
                xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
                name="name"
                targetNamespace="wsdl-namespace" >

                <!-- types, provide data type definitions used to describe the messages exchanged -->
                <wsdl:types>
                               <xsd:schema targetNamespace="wsdl-namespace" xmlns:xsd1="xsd1-namespace" xmlns:jxb=http://java.sun.com/xml/ns/jaxb jxb:version="1.0" >
                                               <xsd:import namespace="xsd1-namespace" schemaLocation="xsd1.xsd" />
                               </xsd:schema>
                </wsdl:types>

                <!-- message, represents an abstract definition of the data being transmitted. A message consists of logical parts, each of which is associated with a definition within some type system. -->
                <!-- Requests -->
                <wsdl:message name="msg1Request">
                               <wsdl:part element="xsd1:msg1" name="content" />
                </wsdl:message>
                …

The relevant part of the XSD where messages are defined :
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns=http://www.w3.org/2001/XMLSchema
xmlns:tns="xsd1-namespace"
                xmlns:xsd2="xsd2-namespace"
                xmlns:jxb=http://java.sun.com/xml/ns/jaxb
targetNamespace="xsd1-namespace"
                elementFormDefault="qualified" jxb:version="1.0">

                <import namespace="xsd2-namespace" schemaLocation="xsd2.xsd" />

                <element name="msg1">
                               <complexType>
                                               <sequence>
                                                               <element name="metadata" type="tns:MetaDataType" />
                                               </sequence>
                               </complexType>
                </element>
                …
