Ksoap and SOAPStruct

Hi
I am a newby in java j2me and KSOAP and I must
programm a client in j2me who must communicate with
SOAP:Lite.
I would like to realize this structure with KSOAP.
and I would like to create this SOAP request  with a
array of SOAPStruct I didn't find example on this web
site and the web, but I know that is possible
:(http://ksoap.enhydra.org/software/documentation/round-2-base/index.html)
I would like to discover the code (maybe this request 
is  built with a vector):

<SOAP-ENV:Envelope xmlns:n2="http://soapinterop.org/"
xmlns:n1="http://soapinterop.org/xsd"
xmlns:n0="http://xml.apache.org/xml-soap"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<n2:echoStructArray id="o0" SOAP-ENC:root="1">
<inputStructArray xsi:type="SOAP-ENC:Array"
SOAP-ENC:arrayType="n1:SOAPStruct[2]">
<item xsi:type="n1:SOAPStruct">
<varString xsi:type="xsd:string">Hello
World</varString>
<varInt xsi:type="xsd:int">42</varInt>
<varFloat xsi:type="xsd:float">123.45</varFloat>
</item>
<item xsi:type="n1:SOAPStruct">
<varString xsi:type="xsd:string">Hello
World</varString>
<varInt xsi:type="xsd:int">42</varInt>
<varFloat xsi:type="xsd:float">123.45</varFloat>
</item>
</inputStructArray>
</n2:echoStructArray>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
has someone got an example 
thank an advance
Maria
