Hi,
I have a problem with Jasper Report. I have written a report with IReport and I have integrated it in my web project. My report uses a xml data source. When I execute my program,it show this exception: java.io.InvalidClassException: net.sf.jasperreports.engine.base.JRBaseReport; local class incompatible: stream classdesc serialVersionUID = 601, local class serialVersionUID = 10001 You can help my? I use: JBuilder 2005 Tomcat 5.0, j2se 1.4.2 Thank and sorry for my english, Carlo |

or indirectly quoted someone who said : >java.io.InvalidClassException: see [url down] You have stale *.ser serialialised object file. It needs to be regenerated. Exactly what that is, can't tell you. Perhaps with a stack trace or filemon you could figure out which file is stale. See [url down] |
