postgresql - BIRT 报告 postgreSQL DB 上的异常

Question

我在 BIRT 报表设计器上设计了报表设计文件 (test_report.rptdesign)。我可以通过单击 BIRT 报告设计器上的“在 Web 查看器中查看报告”来查看报告。但是，当我尝试使用 TOMCAT 查看报告时，出现“没有可用的报告设计对象”错误。TOMCAT 和“BIRT VIEWER”配置正确。我将“BIRT VIEWER filse”放在“C:\xampp\tomcat\webapps”文件夹下。我已经正确配置了“\birt-viewer\WEB-INF\web.xml”文件。我尝试了示例报告(客户。 rptdesign,TopNPercent.rptdesign) 在 TOMCAT 服务器上，它工作正常。但是，当我尝试使用 postgreSQL 时，它没有用，有异常。我将“test_report.rptdesign”文件放在“C:\xampp\tomcat\webapps\brt-example\report”文件夹下。你能给我一些建议吗？

错误信息如下:

There is no report design object available.

我最终通过在 Eclipse“XML 源”选项卡中编辑以下行解决了这个问题:

<report xmlns="http://www.eclipse.org/birt/2005/design" version="3.2.23" id="1">

我所要做的就是将版本从 3.2.23 更改为 3.2.10。您可以通过直接在记事本中编辑 *.rptdesign 文件来实现。
