Axis2 web service client sample for getting values using web service stub,[you need to pass authentication only if secured the WS]

/* Say this CxLastBill class constructor creates object with Status and Cusomner's lastBillMin */
private Long lastBillMin = null;//getter & setter in code
private String status = null;//getter & setter in code

 public CxLastBill(HashMap hm, String cxRef) {//hm map has authentication and EP,cxRef is the request parameter 
 //Http Authentication 
HttpTransportProperties.Authenticator basicAuthentication = new HttpTransportProperties.Authenticator(); basicAuthentication.setPassword(hm.get("RBMPD")); basicAuthentication.setUsername(hm.get("RBMUS")); 

//Call End point Runtime and set some properties for request
    ECAAccountStub proxy;
    try {
        proxy = new ECAAccountStub(hm.get("RBMEP"));//Endpoint
        proxy._getServiceClient()
