无法运行Jasper报告:系统找不到指定的文件 [英] Unable to run Jasper report : The system cannot find the file specified

问题描述

我在reports\templates\Contractor_Bill.jrxml中有报告，结果在reports\results\中.在Netbeans 6.5中它可以正常工作，但是当我将包含exec jar文件的dist文件夹复制到新位置并运行jar时，它将引发此异常.

I have the reports in reports\templates\Contractor_Bill.jrxml and the results in reports\results\. It works fine in Netbeans 6.5, but when i copy the dist folder containing exec jar file to a new place and run the jar it throws this exception.

我还在新位置创建了报告文件夹，它仍然生成相同的异常.

I also created the report folder in the new place, and it still generates the same exception.
