It seems like you've uploaded your *.jrxml file to JasperReports Server. Uploading jrxml file from Jaspersoft Studio to JasperReports Server replaces references to "repo:" which JasperReports Server understands. Unfortunately, this isn't understood by tomcat by default so it's not finding the 345.jasper file. You can just reference the 345.jasper file from your context root of your servlet.

I design the report by studio , and build the jasper file . if I use reference the 345.jasper file , how to design the report ?
