Hi, We have been using Jasper 0.65 Version for last 3 years. We have a requirement to deliver the Report in the RTF format. According to the 0.65 version, Jasper doesn't support Generation of Reports in the RTF format. We would like to migate to 1.3.4 version, we are amazed to findout that 0.65 reports are not opened in the 1.3.4. We are getting the following exception. Please provide the solution for this problem. Immeidately solution required. Do we have any tool to convert from 0.65 to 1.3.4. code: String jasperFile=application.getRealPath(System.getProperty("file.separator"))+ "reports"+System.getProperty("file.separator")+"xxx.jasper"; File reportFile = new File(jasperFile); JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath()); Getting following exception net.sf.jasperreports.engine.JRException: Error loading object from file : E:SJMHreportsxxx.jasper at net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:92) at net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:64) Caused by: java.io.InvalidClassException: net.sf.jasperreports.engine.base.JRBaseReport; local class incompatible: stream classdesc serialVersionUID = 605, local class serialVersionUID = 10200
