Cmdbuild Ws Soap - error in request with SoapUI

Hi,
I’m using SoapUi to query Cmdbuild webservices.
This is my request

<soap:Envelope xmlns:soap=“http://www.w3.org/2003/05/soap-envelope” xmlns:soap1=“http://soap.services.cmdbuild.org”>
soap:Header
<wsse:Security xmlns:wsse=“http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd” soap:mustUnderstand=“1”>
<wsse:UsernameToken xmlns:wsse=“http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd” xmlns:wsu=“http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd” wsu:Id=“UsernameToken-3”>
wsse:UsernamemyUser</wsse:Username>
<wsse:Password Type=“http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest”>myPwd</wsse:Password>


</wsse:UsernameToken>
</wsse:Security>
</soap:Header>
soap:Body
soap1:getCardList

     <soap1:className>Computer</soap1:className>
  </soap1:getCardList>

</soap:Body>
</soap:Envelope>
