[英]Unable to run Jasper report : The system cannot find the file specified
I have the reports in reports\\templates\\Contractor_Bill.jrxml
and the results in reports\\results\\
. 我在
reports\\templates\\Contractor_Bill.jrxml
中有reports\\results\\
,结果在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. 它在Netbeans 6.5中可以正常工作,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 also created the report folder in the new place, and it still generates the same 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。
