Question

对象类型：

CREATE OR REPLACE type cycle_t as object
(
  rk     NUMBER,
  ndt    date,
  ht     varchar2(40),
  be     number(5),
  count  number(20),
  fy     number(2),
  bih    VARCHAR2(20)
);

收藏类型：

CREATE OR REPLACE type cycle_tab as table of cycle_t;

PACKAGE：

CREATE OR REPLACE PACKAGE shem.Pkg_Bam_rok AS
    type cycle_tab is table of cycle_t;

    PROCEDURE test_proc(i_cf             IN VARCHAR2,
                        i_acm            IN VARCHAR2,
                        o_res            OUT cycle_tab,
                        o_error_message  OUT VARCHAR2);

END Pkg_Bam_rok;
/

BODY：

CREATE OR REPLACE PACKAGE BODY Pkg_Bam_rok AS

    procedure test_proc(i_cf             IN VARCHAR2,
                        i_acm            IN VARCHAR2,
                        o_res            OUT cycle_tab,
                        o_error_message  OUT VARCHAR2)
    is
        v_be  varchar2(20);
    begin
        SELECT 2 into v_be  from dual;
    end test_proc;

end Pkg_Bam_rok;

JDBC_CALL：这是我的proc的调用

final String typeName = "cycle_t";
final String typeTableName = "cycle_tab";

// Get a description of your type (Oracle specific)
final StructDescriptor structDescriptor = StructDescriptor.createDescriptor(typeName.toUpperCase(), connection);        
final ResultSetMetaData metaData = structDescriptor.getMetaData();

CallableStatement call = connection.prepareCall("{call shem..Pkg_Bam_rok.test_proc(?,?,?,?)}"); 
call.setString(1,"asd"); 
call.setString(2,"asd");
call.registerOutParameter(3,Types.ARRAY,typeTableName.toUpperCase());
call.registerOutParameter(4,java.sql.Types.VARCHAR); 
call.execute();

PLS：00306：获取错误的参数或输入错误

编辑：我试过普通的proc它可以工作，但是从包中调用它给出错误

为proc调用获取错误的参数或类型数
