Authenticating web services -- get Invalid Response Code:(401) Unauthorized

Hi,

ich have implemented a websirve in dynpro java (thanks for all the guys who wrote guides for that), but i still have a problem. i have to set username and password for authorization.

i have already tested follwoing code:

reqMo.wdSetInvocationModifier(
		 new IWDWSInvocationModifier() {
		   public void doModifyInvocation(Object port) {
			 // Creating the SOAP Header node.
			 HTTPControlInterface http = HTTPControlFactory.getInterface(port);
			 http.setHTTPProxyUserPass("xxxxx","xxxxxx");
			 
		   }
		   public void doModifyAfterInvocation() {}
		 }
	   );

but i get same message as follows:

Exception on execution of web service with WSDL 

URL 'http://server:port/special/wsdl_report_gen.wsdl' with operation '_-xxxx_-generateReport' in 

interface '{urn:sap-com:document:sap:soap:functions:mc-style}XXXX_REPORT_GEN':
Invalid Response Code: (401) Unauthorized. The requested URL 
was:"http://server:port/sap/bc/srt/rfc/sap/XXXX_report_gen/111/XXXX_report_gen/XXXX_report_gen"; 
nested exception is: 
com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid 
Response Code: (401) Unauthorized. The requested URL 
was:"http://server:port/sap/bc/srt/rfc/sap/XXXX_report_gen/111/XXXX_report_gen/XXXX_report_gen"

any ideas?
