I am developing soap web service. I run it successfully in tomcat. But when i deployed it to weblogic, en error occurred. I am sending username and password to web service from header but an error occurs as below: 

```
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:vw="http://vw.com/">
  <soapenv:Header>
    <username>operator</username>
   <pass>xxxxxx</pass>      
   </soapenv:Header>
   <soapenv:Body>
      <vw:createParams>
       <!--Optional:-->
         <arg0>app1</arg0>
         <!--Optional:-->
         <arg1>All</arg1>
      </vw:createParams>
   </soapenv:Body>

```

```
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <ns0:Fault xmlns:ns0="http://schemas.xmlsoap.org/soap/envelope/"    
                 xmlns:ns1="http://www.w3.org/2003/05/soap-envelope">
         <faultcode>ns0:Server</faultcode>
         <faultstring>javax.xml.soap.SOAPException: Header child element 'username' must be namespace qualified!</faultstring>
      </ns0:Fault>
   </S:Body>
 </S:Envelope>

```
