致電Oracle功能

我有以下功能規格：

 
FUNCTION FUNC_GET_SOMETHING_FROM_DATABASE (IN_parameter1   IN VARCHAR2, 
              IN_parameter2   IN VARCHAR2, 
              IN_parameter3   IN VARCHAR2, 
              IN_parameter4   IN VARCHAR2, 
              IN_parameter5   IN VARCHAR2, 
              IN_parameter6   IN VARCHAR2) 

RETURN REFCURTYP; 

以下是我在Java方法被調用函數中的Oracle：

 
public List<SomeVO> getLogReport(
      String parameter1, String parameter2, String parameter3, 
      String parameter4, String parameter5, 
      String parameter6) throws BlahException, RemoteDataAccessException { 

     Vector<Object> params = new Vector<Object>(); 

     DataCollectionImpl<LogReportVO> someData = new DataCollectionImpl<LogReportVO>(
       LogReportVO.class); 

       // IN Parameters 

     params.add(parameter1); 
     params.add(parameter2); 
     params.add(parameter3); 
     params.add(parameter4); 
     params.add(parameter5); 
     params.add(parameter6); 


     //Out Parameter 
     params.add(new DBParameter(DBParameter.OUT, DBParameter.CURSOR)); 

     try { 
      callStoredProcedure(
        Constants.FUNC_GET_SOMETHING_FROM_DATABASE, params); 
     } catch (RemoteDataAccessException e) { 
      throw new BlahException("LogReportDAO", 
        "getLogReport", e.getMessage(), 
        e.getRealException()); 
     } 
     return someData.getDataCollectionObjects(); 
    } 

我得到的錯誤是：

wrong number or types of arguments in call 

附加信息：

 
protected void callStoredProcedure(String procedureName, Vector params) throws RemoteDataAccessException { 
     callStoredProcedure(getSchema(), procedureName, params); 
    } 

    protected void callStoredProcedure(String schema, String procedureName, Vector params) throws RemoteDataAccessException { 
     callStoredProcedure(getDatasource(), schema, procedureName, params); 
    } 

    protected void callStoredProcedure(String dataSourceName, String schema, String procedureName, Vector params) throws RemoteDataAccessException { 
     getOracleConnection(dataSourceName).callStoredProcedure(
       getFullyQualifiedProcedureName(schema, procedureName), params); 
    } 

    private OracleConnection getOracleConnection(String datasource) { 
     OracleConnection oraConn = null; 
     try { 
      oraConn = new OracleConnection(datasource); 
     } catch (RemoteDataAccessException rdae) { 
      log.fatal("BaseDAO.getOracleConnection " + rdae.getMessage(), rdae); 
     } catch (Exception ie) {  
      log.fatal("BaseDAO.getOracleConnection" + ie.getMessage(), ie); 
     } 

     return oraConn; 
    }

最有可能你的代碼沒有考慮到存儲過程的返回值。

爲什麼不使用標準JDBC方式調用存儲過程呢？它像一個魅力。
