Grails插件：Jasper插件-没有此类报告规范错误

Question

I am getting an error when trying to run any of the demo reports in the Grails Jasper Plugin demo page. I'm thinking I'm missing some configuration, but the plugin doc doesn't give any more detail.

Error 500: Internal Server Error

It looks like the plugin doesn't provide a report at all, at least I can't find any. You will need to create a basic test report in Jasper and then place it within your /reports/ folder.
