使用外部化连接配置文件查看birt报告时出现以下错误。

在 beforeOpen脚本上，我有一个以下脚本

var myresourcefolder = reportContext.getDesignHandle().getResourceFolder();
this.setExtensionProperty("OdaConnProfileStorePath", myresourcefolder + "/reports/reportName.cps")

我在创建报告时跟踪了this。我可能会错过什么？

如果您正在使用任务来呈现报告，则可以设置JDBC连接，而不必配置每个报告以使用它：

IReportRunnable runnable = engine.openReportDesign(design);
IRunAndRenderTask task = engine.createRunAndRenderTask(runnable);
//Where 'conn' is java.sql.Connection
task.getAppContext().put("OdaJDBCDriverPassInConnection", conn);
task.run();
