Probleme bei der Erstellung von Oracle Array aus Liste

Question

Mein Code fließt sehen Vorlieben:

1. Get a list of Attributes from a particular schema. This is ArrayList in type. 
2. The method given below receives the list and does the following 
    a. It converts it to an String/Object Array. 
    b. Connects to another Schema. 
    c. Iterate through a table and get the corresponding values from a field for those attributes. 
    d. Sends back to calling method so that the same can be updated for those attributes in primary schema. 

I Fehler bei folgenden Codezeilen sind immer:

Array itemDesc = ((OracleConnection)conn).createArrayOf("XXJN_PCM_ITEM_LIST", items); 

Error: java.sql.SQLFeatureNotSupportedException: Unsupported feature at oracle.jdbc.driver.PhysicalConnection.createArrayOf(PhysicalConnection.java:15560)

I ojdbc6 Glas in Projekt verknüpft habe und ich habe auch das Glas ojdbc7 benutzt. Aber der gleiche Fehler die ganze Zeit.

Unten ist mein Code:

public HashMap MyMethod(ArrayList list) throws SQLException, Exception { 
     HashMap itemsQtyMap = new HashMap(); 
     PreparedStatement psmt = null; 
     Iterator iter = list.iterator(); 
     ResultSet resultSet = null; 
     String itemNumber = null; 
     double temp = 0; 

     Object [] items = list.toArray(); 
     logger.info("Length of the converted array is " + items.length); 
     OracleDataSource ds = new OracleDataSource(); 
     ds.setURL(PropertyNames.DB_URL); 
     Connection conn = ds.getConnection(PropertyNames.DB_USERNAME,PropertyNames.DB_PASSWORD); 
     logger.info("Connection is "+ conn); 

/*This output in the logger is coming as Connection is oracle.jdbc.driver.T4CConnection@3de779fb */ 
     Array itemDesc = ((OracleConnection)conn).createArrayOf("XXJN_PCM_ITEM_LIST", items); 
     logger.info("Length of Item desc is "+ itemDesc); 

     item = (String[]) list.toArray(item); 
     Array itemDesc = ((OracleConnection) conn).createArrayOf("XXJN_PCM_ITEM_LIST", item); 
*/ 
     oracle.sql.StructDescriptor x = StructDescriptor.createDescriptor("XXJN_PCM_ITEM_QRT_DEM", conn); 
     ResultSetMetaData rsmd = x.getMetaData(); 
     int numberOfColumns = rsmd.getColumnCount(); 
     System.out.println("resultSet MetaData column Count=" + numberOfColumns); 
     for (int i = 1; i <= numberOfColumns; i++) { 
      logger.info("column MetaData "); 
      logger.info("column number " + i); 
      // get the column's name. 
      logger.info(rsmd.getColumnName(i)); 
     } 

     OracleCallableStatement cstmt = (OracleCallableStatement) conn.prepareCall("{ call xxjn_pcm_item_dem.item_qrt_dem(?,?)}"); 
     cstmt.setArray(1, itemDesc); 
     cstmt.registerOutParameter(2, OracleTypes.ARRAY, "XXJN_PCM_ITEM_QRT_DEM_TBL"); 
     cstmt.execute(); 
     // Object[] dem = (Object[])cstmt.getObject(2); 
     // Array dem = cstmt.getArray(2); 
     Object[] dem = (Object[]) ((Array) cstmt.getObject(2)).getArray(); 

     System.out.println("length=" + dem.length); 
     for (Object tmp : dem) { 
      logger.info("Inside for Loop for Object TMP"); 
      OracleStruct row = (OracleStruct) tmp; 


      Object[] attrs = row.getAttributes(); 

      // Attributes are index 1 based... 
      // String sqlt = row.getSQLTypeName(); 
      //System.out.println("Item Number = " + (String) attrs[0]); 
      DemandPopulationBean bean = new DemandPopulationBean(); 
      bean.setItemNumber((String) attrs[0]); 
      bean.setQ1Demand(((BigDecimal) attrs[1]).doubleValue()); 
      bean.setQ1Demand(((BigDecimal) attrs[2]).doubleValue()); 
      bean.setQ1Demand(((BigDecimal) attrs[3]).doubleValue()); 
      bean.setQ1Demand(((BigDecimal) attrs[4]).doubleValue()); 

     } 
     logger.info("---"); 

     //cstmt.close(); 
     return itemsQtyMap; 
    }

Das Problem nun behoben ist. Just closed eclipse und Projekt von Grund auf neu erstellt, es hat dieses Mal für mich funktioniert. Ich habe ojdb7 Glas verwendet.
