SAXException: bad envelope tag

问题:

I'm trying to connect to a webservice https protected through a webservice client. Eclipse generated a stub based webservice client and looks nice to me. The problem comes when I try to call a method from the webservice:

String a = (String)webservice.userProfileServices(xml);

I'm also using the following SOAP headers:

esgGatewayPort = (new EsgGatewayLocator()).getesgGatewayPort();

//setting the authentication header
PrefixedQName name = new PrefixedQName("http://schemas.xmlsoap.org/ws/2002/07/secext","Security","wsse");
System.out.println("Setting headers for authentication");
org.apache.axis.message.SOAPHeaderElement sh = new org.apache.axis.message.SOAPHeaderElement(name);
SOAPElement sub;

try {

      String clntUserName="myUser";
      String clntPassword="myPassword";
      sub = sh.addChildElement("UsernameToken");
      SOAPElement element = sub.addChildElement("Username");
      element.addTextNode(clntUserName);
      element = sub.addChildElement("Password");
      element.addTextNode(clntPassword);
      ((org.apache.axis.client.Stub) esgGatewayPort).setHeader(sh);

} catch (SOAPException e) {

      e.printStackTrace();

}

I receive the following:

Any help will be truly appreciated.
