    basicHttpBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
    EndpointAddress epa = new EndpointAddress("http://sewsr2.sewinfra.com:8002/webservices/SOAProvider/plsql/fnd_user_pkg/");
    FND_USER_PKG_PortTypeClient port = new FND_USER_PKG_PortTypeClient(basicHttpBinding,epa);
    port.ClientCredentials.UserName.UserName ="asadmin";
    port.ClientCredentials.UserName.Password = "welcome";
    SOAHeader header = new SOAHeader();
    InputParameters10 input = new InputParameters10();
    header.RespApplication = "FND";
    header.Responsibility = "FND_REP_APP";
    header.SecurityGroup = "STANDARD";
    header.NLSLanguage = "AMERICAN";
    header.Org_Id = "115";
    input.X_USER_NAME = "sysadmin";
    OutputParameters4 ouput = port.TESTUSERNAME(header, input);
    int value = ouput.TESTUSERNAME.Value;
