Hi All, We have on old linux server (SunOS 5.9) with old .jasper files with same name .xml files (didn't see any jrxml files) and we want to investigate all the .jasper files/reports to evaluate what was done etc. Looked up a lot of post on this blog but didn't see how I can view or decompile those .jasper reports to see what was done on them (report logic, calculations, filters etc) except one about Jaspersoft Studio. Moved the files over to my windows laptop and tried opening/previewing it as per its instructions but get an error (see below). Any assistance would be greatly appreciated. net.sf.jasperreports.engine.JRException: Error loading object from InputStream. at net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:230) Caused by: java.io.InvalidClassException: net.sf.jasperreports.engine.base.JRBaseReport; local class incompatible: stream classdesc serialVersionUID = 606, local class serialVersionUID = 10200 at java.base/java.io.ObjectStreamClass.initNonProxy(Unknown Source)
