weblogic Ws-security policy vs oasis policy

Hi all.

We are trying to configure ws-security on a webservice deployed on Weblogic 10.3.6: the purpose is to permit the execution of the ws only if authenticated.

So, we created an user ("dummy") into the default weblogic realm and communicated the credentials to who develops the client of this webservice.

He has released a test Envelope running by SOAP-UI

<soapenv:Envelope xmlns:sch="http://com.webservices.amm.standalone.key.provider/schema.xsd" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header>
     <wsse:Security soapenv:mustUnderstand="1" 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
