我是JasperReports和iReport Designer的新手。我的客户希望使用JasperReports技术来迁移/开发所有报告。注意：我没有Java体验iReport 4.5.1使用JasperServer 4.5和Oracle DB存储过程使用引用游标 - 已关闭
在过去的几天里，我通过JasperReports进行了一些挖掘和导航，这是我迄今为止的地方。
我使用iReport设计器来设计我的报告。
在我的SQL语句和过程下面，我已经编译好了，并且在Oracle SQL Developer编辑器中一切正常。

我现在去了iReport的设计师建立一个数据库连接，并创建一个数据集来叫我的程序如下图所示
{call PUBLISHER_AND_BOOKS($P{P_PUBLISHER_ID}, $P{ORACLE_REF_CURSOR})}
当我点击阅读字段获得字段从列表我的方法我收到以下错误消息
Error: SQL problems: Invalid column type.
所以我通过单击确定进行手动添加字段到reprot，当我预览报告时I g没有错误信息。所以我查看了我的DataSource/DataSet，通过右键单击报表名称和查看查询它是空白的，所以我给出了上面提到的过程名称，当点击下一个时，我得到了同样的错误信息
现在我无法连接或创建一个数据集继续我的报告设计
如果任何人都可以帮助解决此问题，以便我可以继续进行报告设计，那将会非常有帮助。
注
1.我在报告查询设置查询语言PLSQL
2.定义光标PARAM为java.sql.ResultSet中有也试过--- NO LUCK, same error
3我已经在我的类路径符合PlSqlQueryExecuter类出口
4.我已经看过这样的：

所以任何人都^ h另一个解决方案，我可以继续使用我的使用sys_refcursor的存储过程。
另外一个工作教程链接或博客将是一个很大的帮助。
在此先感谢。
