For the following WSDL element and type: -

<complexType name='Person'>
<sequence>
<element name="request" minOccurs="0">
<complexType>
<all>
<element minOccurs="0" maxOccurs="1" name="surname" nillable="true" type="string"/>
</all>
</complexType>
</element>
</sequence>
</complexType>

<element name='lookup' type='tns:Person'/>

If this element is referenced from the message and wstools is configured with a parameter-style of wrapped then two classes are generated: -

'LookupRequest.java' and 'Lookuprequest.java', this second class should not be generated.

In addition to this the generated JAX-RPC mapping needs to handle the case of the type correctly.
