I am using JasperReports 0.4.4 (And I can not upgrade to a newer version). I need to write a new report (And have done so) but can not compile into a format that is excepted. My current error is java.io.StreamCorruptedException dori.jasper.engine.JRException: Error loading object from file : c:toolsreportsUserHistory.jasper Any help or advice on how to get a file into the correct .jasper format for use by 0.4.4 would be greatly appreciated. (I looked into iReport, but version 0.2.0 starts with JasperReports 0.4.5)
