服务器中的 JasperReports 异常不支持嵌套事务在本地主机中工作正常
Nested transactions not supported JasperReports exception in server works fine in localhost
我必须继续使用 JSF 开发 Web 应用程序。它使用 Jasper Reports 生成 PDF 文件。它在本地主机上运行良好，没有警告，没有错误，一切正常。但是，当我上传到 VPS 时，它不起作用，这很奇怪，因为代码是相同的。我的电脑是 Ubuntu 15.04，Glassfish 4.1 和 Oracle Java 8。服务器有一个 Ubuntu 14.04 服务器，Glassfish 4.1 和 Oracle Java 7。
根据服务器glassfish的日志文件，是数据库有问题，但不知道是什么原因。本地主机和服务器使用相同版本的 MySQL 并且数据库的定义是相同的。实际上，我可以登录服务器，所以我可以访问数据库。
服务器中是否有必须不同的配置？
有人知道我应该找什么吗？
这些是错误：
错误 1

更新：
我删除了 PDF 的所有页面，除了一页，即：
这已经不是了
JasperPrint jasperPrint2 = JasperFillManager.fillReport(reporte2, map, conn); //THIS RISES AN ERROR
JasperPrint jasperPrint3 = JasperFillManager.fillReport(reporte3, map, conn);
JasperPrint jasperPrint4 = JasperFillManager.fillReport(reporte4, map, conn);
JasperPrint jasperPrint5 = JasperFillManager.fillReport(reporte5, map, conn);
代码中只有这个，而且有效！
JasperPrint jasperPrint = JasperFillManager.fillReport(reporte, map, conn);
但我需要所有页面，而不仅仅是一页。
我已经修好了。我仍然不知道为什么它以前在服务器中不起作用，而在本地主机中却起作用。无论如何，我已经在 Reportes.java crearPDF(...) 中更改为：
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
作者：
Session session = HibernateUtil.getSessionFactory().openSession();
在函数的末尾，我在 finally 块中调用了 session.close()。
我必须继续使用 JSF 开发 Web 应用程序。它使用 Jasper Reports 生成 PDF 文件。它在本地主机上运行良好，没有警告，没有错误，一切正常。但是，当我上传到 VPS 时，它不起作用，这很奇怪，因为代码是相同的。我的电脑是 Ubuntu 15.04，Glassfish 4.1 和 Oracle Java 8。服务器有一个 Ubuntu 14.04 服务器，Glassfish 4.1 和 Oracle Java 7。 根据服务器glassfish的日志文件，是数据库有问题，但不知道是什么原因。本地主机和服务器使用相同版本的 MySQL 并且数据库的定义是相同的。实际上，我可以登录服务器，所以我可以访问数据库。
服务器中是否有必须不同的配置？ 有人知道我应该找什么吗？
这些是错误：

更新：
我删除了 PDF 的所有页面，除了一页，即：
这已经不是了
JasperPrint jasperPrint2 = JasperFillManager.fillReport(reporte2, map, conn); //THIS RISES AN ERROR
JasperPrint jasperPrint3 = JasperFillManager.fillReport(reporte3, map, conn);
JasperPrint jasperPrint4 = JasperFillManager.fillReport(reporte4, map, conn);
JasperPrint jasperPrint5 = JasperFillManager.fillReport(reporte5, map, conn);
代码中只有这个，而且有效！
JasperPrint jasperPrint = JasperFillManager.fillReport(reporte, map, conn);
但我需要所有页面，而不仅仅是一页。
我已经修好了。我仍然不知道为什么它以前在服务器中不起作用，而在本地主机中却起作用。无论如何，我已经在 Reportes.java crearPDF(...) 中更改为：
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
作者：
Session session = HibernateUtil.getSessionFactory().openSession();
在函数的末尾，我在 finally 块中调用了 session.close()。
