When Domino is used to create a webservice consumer, it does not provide an easy way to add SOAP headers to method calls. To do so, extend the STUB class it provides, copy any methods that need SOAP headers, and insert a line after the 'createCall' to provide that functionality. See snippet 69125 for the details of the 'createSessionHeader' code.

add_session_header.java

public QueryService_pkg.QueryResult queryFirst(QueryService_pkg.QueryRequest request) throws java.rmi.RemoteException {
  lotus.domino.websvc.client.Call _call = createCall("queryFirst");
  _call = createSessionHeader(_call);
  java.lang.Object _resp = _call.invoke(new java.lang.Object[] {request});
  this.queryHeader = _call.getResponseMessage().getSOAPEnvelope().getHeaderByName(new QueryServiceLocator().getServiceName().getNamespaceURI(), "QueryHeaderValue");
  return (QueryService_pkg.QueryResult) _call.convert(_resp, QueryService_pkg.QueryResult.class);
}
