I am using iReport 4.5 and JasperReport Server 4.5 on EC2 via a Bitnami image. My data source is a remote XML file. I am able to create a report just fine in iReport but I get this error when I try to deploy the jrxml file. I've browsed these forums and a lot of the fixes talk about compatibility. I actually downgraded from iReport 4.6 for this very reason, after setting iReport 4.6 compatibility to 4.5 did not work. I also tried saving my jrxml file as UTF-8 without any luck.
