Web Services - Username / password

Question

Hi,
I was just playing around with web-services and wanted to create a simple web-service where a client will send a username/password to a web-service running on a local Tomcat server (port 8080). In response, the service will return a "hello <username>" and display a password valid message on the client side. I am writing both the client code as well as the server code using the Java/axis classes. I have the following code so far .. please let me know if I have done it correctly and how do I proceed with writing the service-code?
//the client that sends a username and requests a webService
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
public class ClientDOC
     public static void main(String args[])
          try
               String sEndpoint = "http://localhost:8080/axis/services/RPCuser";
               String sOperationName = "HelloUser";
               String sUserName = String.parseString(arg[0]);
               String sPassword = String.parseString(arg[1]);
               //making connection
               Service userNameService = new Service();
               Call SOAP_call = new Call(userNameService.createCall());
               SOAP_call.setTargetEndPointAddress(new java.net.URL(sEndpoint));
               SOAP_call.setUsername(sUserName);
               SOAP_call.setPassword(sPassword);
               SOAP_call.setOperationName(new java.lang.string(sOperationName));
               System.out.println("Calling HelloUser Service");
               System.out.println(call.invoke(new Object[]{} );
          catch (Exception e)
               System.err.println(e.toString());
Web-Service
~~~~~~~~~~
package services.RPCuser;
public class ServiceRPC
     public String HelloUser(void)
          try
               String sMsg = null;
               //TODO? How do get the Username and Password parameter
               String sUserName = ;
               String sPassword = ;
               if (sPassword == "pass")
                    sMsg = "Hello "+sUserName;
               else
                    sMsg = "Invalid Password";
          catch (Exception e)
               System.err.println(e.toString());
}
