java调用以下存储过程时报错：

--1.创建一个包，在该包中定义了一个游标类型yh_cursor1
create or replace package testpackage as type test_cursor is ref cursor;
end testpackage;

--2.创建存储过程
create or replace procedure sp_13(spNo in number,p_cursor out testpackage.test_cursor) is begin open p_cursor for select * from emp where deptno=spNo;
end sp_13;

console打印的异常信息：

解决办法：

用oracle自带ojdbc14.jar (1.5m)替换weblogic81/server/lib下的ojdbc14.jar(1.3m)
