Namespace problem with added header

Question

I have a client request handler which needs to add an authentication header of the form:
<Security>
   <UsernameToken>
      <Username>username</Username>
      <Password>password</Password>
   </UsernameToken>
</Security>     The key code which does this in the request handler is:
SOAPHeaderElement she = shd.addHeaderElement(senv.createName(SIGN_HEADER_NAME));
she.setMustUnderstand(true);
she.addNamespaceDeclaration("", SIGN_HEADER_URI);
SOAPElement selToken = she.addChildElement(SIGN_HEADER_TOKEN);
SOAPElement selUser = selToken.addChildElement(SIGN_HEADER_USERNAME);
selUser.addTextNode(username);
selUser = selToken.addChildElement(SIGN_HEADER_PASSWORD);
selUser.addTextNode(password);But what I end up with is:
<Security soapenv:mustUnderstand="1" xmlns:soapenv=...
       xmlns="http://demo">
   <UsernameToken  xmlns="">
      <Username>username</Username>
      <Password>password</Password>
   </UsernameToken>
</Security>     The attributes on the Security element are correct, but the xmlns="" attribute on the UsernameToken element is the problem. The SOAP classes/methods are clearly namespace aware and are essentially saying with xmlns="" that it doesn't know the namespace of UsernameToken and the following elements.
I tried dropping some wsdl for the security elements in the wsdl directory of the client, but it seems to need some programmatic hookup.
I have defined the handler in the webservicesclient.xml as:
         <handler id="Handler_1128108948956">
            <description>Adds an authentication header with username & password</description>
            <handler-name>utils.SOAP_Auth_Handler</handler-name>
            <handler-class>utils.SOAP_Auth_Handler</handler-class>
            <soap-header id="SOAPHeader_1128460509232">
               <namespaceURI>http://demo</namespaceURI>
               <localpart>Security</localpart>
            </soap-header>
         </handler>How do I keep the soap methods from adding on the xmlns="" to the UsernameToken element?
I'm running WebSphere App Developer 5.0.2.9.

Answer 1

Can't you use the removeNamespaceDeclaration method?
public boolean removeNamespaceDeclaration(String prefix)Removes the namespace declaration corresponding to the given prefix.
Parameters:
prefix - a String giving the prefix for which to search
Returns:
true if the namespace declaration was removed successfully; false if it was not
