Parameter name as Param0

[Wishing Carebear]

Hello:I'm new to axis2. Trying the pojoguide samples of Weatherservice with
a complextype Weather.

When looking into the wsdl, noticed the Weather complexType has name as
param0 as shown below:

<xs:element name="setWeather">

   <xs:complexType>

        <xs:sequence>
             <xs:element minOccurs="0" name="param0" nillable="true"
type="ax22:Weather"/>
        </xs:sequence>
   </xs:complexType>
</xs:element>

Wondering if it is possible to give a logicalname.

Thanks,
Ravi
