A JAX-WS client is generating the fllowing payload by parsing this WSDL and Schema file(s).

In my Perl client I write the following....I am skipping some generic send request parts...

# ------------------- getAllLocalGroups() ----------------------------
sub LocalGroupProvider::getAllLocalGroups()
{
    my $this = shift;
    my ($rawJson, $methodRef, $inputRef) = @_;

    my $method = SOAP::Data->new(
            'name' => $this->{'Hyas'}->getMethod(),
            'prefix' => 'ns0' );
    my $provider = $this->{'Hyas'}->getProvider();
    $method->attr({
            'xmlns:ns0' => "http://www.bluearc.com/BAService/$provider
+"  });
   
    $$methodRef = $method;

    my $jbuf = {};
    if ( $rawJson )
    {
        my $job = JSON->new();
        $jbuf = $job->decode($rawJson);
    }
   
    my $evsId = SOAP::Data->new(
            'name' => 'evsId',

            );

    @$inputRef = ($evsId);
    return(1);

I see that your code is generating

  <S:Body>
    <ns0:getAllLocalGroups>
      <ns0:evsId xsi:type="xsd:unsignedShort">evsId</ns0:evsId>
    </ns0:getAllLocalGroups>
  </S:Body>
[download]

I would like to generate this

  <S:Body>
    <ns0:getAllLocalGroups> 1 </ns0:getAllLocalGroups>
  </S:Body>
[download]

Please show me how you would use SOAP::Lite to generate that.

Again, note there is no element called evsId, the value of evsId is placed in an element that is also the methodName, that of "getAllLocalGroups".
