jdbc怎么处理存储过程返回的游标啊?谢谢,急(内有代码)

[yxh101]

create or replace package test_age
as
type mycursor is ref cursor;
procedure get_all(op_cur out mycursor);

end test_age;
/

create or replace package body test_age as
procedure get_all(op_cur out mycursor) is
begin
open op_cur for select name from mytbl;
end;
end test_age;

/

调用:

String procedure = "{call test_age.get_all(?) }";
CallableStatement cstmt = conn.prepareCall(procedure);
try{
cstmt.registerOutParameter(1,xxxxxxxxx);
//请问此处给如何注册输出参数呢?


}catch(Exception e)
{
System.out.println(e.toString());
}
