Can anyone provide me the sample code to set username and password for a Apex code callout. I see most of the people set certification. But i am looking for some sample code where in we can set user name and password to the webservice client call.

In my case i am trying to consume a SAP Wervice from Apex code generated by WSDL.

My client call is

 System.debug(' callservice begin -- ');
    sapComDocumentSapRfcFunctions.ZCUSTOMER_HELPPortType stub  = new sapComDocumentSapRfcFunctions.ZCUSTOMER_HELPPortType();
    sapComDocumentSapRfcFunctions.ZCUSTOMER_HELP_Response_element result = stub.ZCUSTOMER_HELP(1,'jay');
    System.debug('result ---'+result);

Following is the error i am getting

11:16:14:220 CALLOUT_RESPONSE [28]|This service requires client certificate for authentication procedure.

 I am making just a http call. Do i need to setup any credentials for this like user name and password..? how can i set them .

Help is appreciated.

Web service callout failed: Unexpected element. Parser was expecting element 'http://schemas.xmlsoap.org/soap/envelope/:Envelope' but found ':html'

I debugged in Execute Anonymous using the test code 

When I do this I get a com.sforce.ws.SoapFaultException.

Can anyone please help.
