带有Out参数的Stored Proc调用中的列索引无效

Question

get对象上抛出了无效的列索引错误。 正在调用Proc并设置参数的Java代码：

        public Object[] order(HttpServletRequest request,
              String userId,
              String tName,
              String aCodes,
              String aFinCodes,
              String oType,
              int iBase,
              String cFinCodes
             ) throws xyzSqlException{

        Connection conn = null;
        CallableStatement cstmt=null;
        ResultSet rsTempHead = null;
        ResultSet rsTempDetails = null;
        int notdisplayedRows = 0;
        Object[] oTempList = null;

                        ds = getDataSource(installBase);

                        try
                        {
                            conn = ds.getConnection();

                            OrdEntDTO tempDetailsDTO= null;

                                cstmt = conn.prepareCall("{call get_temp_details (?,?,?,?,?,?,?,?,?)}");

                            cstmt.setString(1,userId);
                            cstmt.setString(2,tName);
                            cstmt.setString(3,aCodes);
                            cstmt.setString(4,Utility.convertSQLStringIN(aFinCodes,","));
                            cstmt.setString(5,oType);
                            cstmt.registerOutParameter(6, -10);
                            cstmt.registerOutParameter(7, -10);
                            cstmt.registerOutParameter(8,Types.NUMERIC);
                            cstmt.setString(9,Utility.convertSQLStringIN(cFinCodes,","));
                            rsTemplateHeader =(ResultSet)cstmt.getObject(6);
                            rsTemplateDetails =(ResultSet)cstmt.getObject(7);
                            notdisplayedRows = cstmt.getInt(8);
                            logger.debugMsg("The notdisplayedRows " + notdisplayedRows);
                                int listIndex = 0;
                                if(rsTemplateDetails != null)
                                {
                                    oTempList = new Object[501] ;
                                }
}

步骤：

   CREATE OR REPLACE PROCEDURE get_temp_details (userid                  IN       VARCHAR2,
    tname            IN       VARCHAR2,
    acode              IN       VARCHAR2,
    afincode           IN       VARCHAR2,
    otype               IN       VARCHAR2,
    refcur1                 OUT      sys_refcursor,
    refcur2                 OUT      sys_refcursor,
    temp_ord_status   OUT      NUMBER,
    cFinCodes      IN       VARCHAR2
)
