如何使用Java JDBC从Oracle存储过程中检索数组

Question

在我的Oracle数据库中，我输入

CREATE OR REPLACE TYPE DOSSIER_RESULT AS OBJECT
(
  id           number,
  user_id      number
)

此对象的集合

CREATE OR REPLACE TYPE DOSSIER_RESULTS_ARRAY AS TABLE OF DOSSIER_RESULT

还有一个具有最后一个类型的OUT参数的过程

 procedure get_dossier(i_search_mode           in number,
                        i_person_id             in number,
                        i_case_num              in varchar2,
                        i_auto_num              in varchar2,
                        o_dossier_results_array out dossier_results_array)

在Java代码中，我有

public static void getDossierTest(Dossier obj) {

        LOGGER.info("------obj: " + obj);

        Connection conn = null;
        CallableStatement callableStatement = null;
        ResultSet rs = null;
        try {
            conn = DbConnection.getConnection(DbConnection.CONN_SU);
            Map map = conn.getTypeMap();
            map.put("DOSSIER_RESULT", Class.forName("data.DossierSearchResultsModel"));
            conn.setTypeMap(map);

            callableStatement = conn.prepareCall("{call pkg_1av_test.get_dossier(?,?,?,?,?)}");

            callableStatement.setInt(1, 1);
            callableStatement.setLong(2, obj.getId() == null ? 0 : obj.getId());
            callableStatement.setString(3, obj.getNum() == null ? "" : obj.getNum());
            callableStatement.setString(4, obj.getGrnz() == null ? "" : obj.getGrnz());
            callableStatement.registerOutParameter(5, java.sql.Types.ARRAY);

            callableStatement.execute();

            Array array = callableStatement.getArray(5);

            for (Object item : (Object[]) array.getArray()) {
                if (item instanceof DossierSearchResultsModel) {
                    LOGGER.info("------------Got that: " + item.toString());
                }
            }

        } catch (Exception e) {
            e.printStackTrace();
        } 

    }

但是在

callableStatement.registerOutParameter(5, java.sql.Types.ARRAY);

我收到以下错误：

ORA-03115: An unsupported network data type or data representation

请帮忙！我究竟做错了什么？ 我需要使用Java代码从Oracle存储过程中获取该数组（或collection）

和模型类
