java調用以下存儲過程時報錯：

--1.創建一個包，在該包中定義了一個游標類型yh_cursor1 create or replace package testpackage as type test_cursor is ref cursor; end testpackage;--2.創建存儲過程 create or replace procedure sp_13(spNo in number,p_cursor out testpackage.test_cursor) is beginopen p_cursor for select * from emp where deptno=spNo; end sp_13;

console打印的異常信息：

解決辦法：

用oracle自帶ojdbc14.jar (1.5m)替換weblogic81/server/lib下的ojdbc14.jar(1.3m)
