xsi:type attribute not set in SOAP request

[georgesberscheid]

Hi,

I generated client artifacts from a WSDL file using wstools and I'm trying to consume a third-party web service. However the server seems to expect xsi:type attributes to be set in the request which the generated web service client doesn't do.

This is the fragment from the WSDL file:

<xsd:element name="login">
 <xsd:complexType>
 <xsd:sequence>
 <xsd:element name="username" type="xsd:string" maxOccurs="1" minOccurs="1"></xsd:element>
 <xsd:element name="password" type="xsd:string" maxOccurs="1" minOccurs="1"></xsd:element>
 </xsd:sequence>
 </xsd:complexType>
</xsd:element>

The generated SOAP request looks as follows:

<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
 <env:Header />
 <env:Body>
 <ns1:login xmlns:ns1='http://testuri.org' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
 <username>TestUser</username>
 <password>MySecretPassword</password>
 </ns1:login>
 </env:Body>
</env:Envelope>

This generates the following error message from the server: "server error. invalid method parameters"

However , if I (manually, using a debugger in org.jboss.ws.soap.SOAPConnectionImpl.call()) change the request string to include xsi:type for the parameters, the request is successfully accepted by the server:

<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
 <env:Header />
 <env:Body>
 <ns1:login xmlns:ns1='http://testuri.org' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
 <username xsi:type="xsd:string">TestUser</username>
 <password xsi:type="xsd:string">MySecretPassword</password>
 </ns1:login>
 </env:Body>
</env:Envelope>

How do I make JBossWS add the parameter types to the request?
Thanks,

Georges
