java调用c# 写的webservices有关问题

java调用c# 写的webservices问题
c# 写的webservices如下:
/// <summary>
    /// WebServiceIPDA  Ver 2.1
    /// </summary>
    [WebService(Namespace = "http://qqbbxpddddd.xicp.net/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
    // [System.Web.Script.Services.ScriptService]
    public class WebServiceIPDA : System.Web.Services.WebService
    {
        /// <summary>
        /// 数据库连接字符串
        /// </summary>
        private string _ConnectionStr;

        /// <summary>
        /// 数据库连接对象
        /// </summary>
        private MMS.Public.DbAccLibry.DbAccess DataBaseSrvConn;

        /// <summary>
        /// 构造函数
        /// </summary>
        public WebServiceIPDA()
        {
            //MMS.Public.DbAccLibry.Config cfg = new MMS.Public.DbAccLibry.Config();
            //cfg.ConfigType = MMS.Public.DbAccLibry.ConfigFileType.AppConfig;
            //string sysConfigFile="web.config";

            _ConnectionStr = "Server=localhost;Database=jcSystemData;User ID=sa;Password=newman2007;Connect Timeout=50;Pooling=True;Min Pool Size=1;Max Pool Size=100;Persist Security Info=False;Asynchronous Processing=true;Integrated Security=false;";

            //_ConnectionStr=System.Configuration.ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString;

            //_ConnectionStr=cfg.GetConfigValue(sysConfigFile, "connectionString").ToString();

            DataBaseSrvConn = new MMS.Public.DbAccLibry.DbAccess();
            DataBaseSrvConn.DatabaseInint(MMS.Public.DbAccLibry.DataBaseType.MsSqlServer, _ConnectionStr);
        }

        /// <summary>
        /// 业务员登录
        /// </summary>
        /// <param name="aUserID">业务员编号</param>
        /// <param name="aPWD">业务密码</param>
        /// <returns>成功返回：'T',失败返回'F'</returns>
        [WebMethod]
        public string Login(string aUserID, string aPWD)

        {
            string result = "T";
            try
            {
                IDataParameter[] parms = new SqlParameter[] { new SqlParameter("@v_UserID", aUserID), new SqlParameter("@v_PWD", aPWD) };

                DataSet dsLogin = DataBaseSrvConn.ExecuteDataSet(CommandType.StoredProcedure, "jcp_CheckBusLogin", parms);

                if (!(dsLogin.Tables[0] != null && dsLogin.Tables[0].Rows[0]["Result"].ToString().Trim() == "T"))
                {
                    result = "F";
                }
            }
            catch
            {
                result = "F";
            }
            return result;
        }
}
 
c#调用方法:
IPADWebservicesTest.ServiceReference1.WebServiceIPDASoapClient my = new IPADWebservicesTest.ServiceReference1.WebServiceIPDASoapClient();  
string flag = my.Login("00001", "9:;<=>");
能正常调用并返回
Java调用如下:
String ss=client.login("00001","9:;<=>");
System.out.Printin(ss);
