Jdbc JasperReports服务器“作业无法执行”

我是JasperReports服务器的新手，一直在寻找解决此问题的方法。我什么也没找到。我继承了此服务器，报告未按计划运行

Job: 3rd (ID: 61)
Report unit: /reports/Scheduled/00_Schedule_Primer
Quartz Job: ReportJobs.job_61
Quartz Trigger: ReportJobs.trigger_62_1
Exceptions:

An error occurred while executing the report.

我甚至不知道从哪里开始解决这个问题。任何帮助都会很棒

您的连接url、用户名和密码值似乎不正确。如果这三项都正确，则将创建连接。请检查您的Jasper服务器配置
