BIRT 查看器报告错误答案

【问题标题】：BIRT Viewer Reporting ErrorBIRT 查看器报告错误
【发布时间】：2011-01-26 17:56:09
【问题描述】：

我最近在 CentOs Linux 机器上的 tomcat 中安装了 BIRT Viewer Version : 2.6.1。我们最初认为我们已经成功安装了它，因为我们的报告工作正常。但是，我们现在收到一条错误消息，我们无法解决。我们正在从 postgresql 数据库中提取数据，并将驱动程序放在正确的位置。我们在尝试运行报告时收到的错误消息如下：

org.eclipse.birt.report.service.api.ReportServiceException: Error happened while running the report.

使用以下堆栈跟踪：

日志文件似乎表明 postgresql 无法找到某个类，但我们的文件位于正确的位置。

谁能提供任何见解或帮助？

谢谢

【问题讨论】：

究竟哪个位置是“正确位置”，以及您将哪个文件作为 postgresql 驱动程序放置？该报表是否在报表设计器中工作？
报表正在报表设计器中工作，postgresql 驱动程序位于：birt-viewer\WEB-INF\platform\plugins\org.eclipse.birt.report.data.oda.jdbc \驱动程序。该文件是 postgresql 驱动程序。
文件为：postgresql-9.0-801.jdbc4.jar

标签： database postgresql birt

【解决方案1】：

尝试将 JDBC 驱动放在其中之一

lib 你的应用服务器目录（tomcat/lib 或者适合你的服务器的东西）
birt-viewer/WEB-INF/lib

您会更加确定驱动程序在 JVM 类路径中可用。

【讨论】：

我们尝试了这个并重新启动了tomcat。它工作了大约一天，但现在我们又遇到了同样的问题。
