stream classdesc serialVersionUID = 406

2003-07-31 08:30

When I try to generate my PDF using JSP I get this message:

 

java.io.InvalidClassException: dori.jasper.engine.base.JRBaseReport; local class incompatible: stream classdesc serialVersionUID = 406, local class serialVersionUID = 500

 

 

The code I used is:

 

<%@ page errorPage="error.jsp" %>

<%@ page import="datasource.*" %>

<%@ page import="dori.jasper.engine.*" %>

<%@ page import="java.util.*" %>

<%@ page import="java.io.*" %>

 

<%

File reportFile = new File(application.getRealPath("/reports/etiquetas.jasper"));

 

Map parameters = new HashMap();

 

byte[] bytes =

JasperRunManager.runReportToPdf(

reportFile.getPath(),

parameters,

new WebappDataSource()

);

 

response.setContentType("application/pdf");

response.setContentLength(bytes.length);

ServletOutputStream ouputStream = response.getOutputStream();

ouputStream.write(bytes, 0, bytes.length);

ouputStream.flush();

ouputStream.close();

%>

I met the same problem when I tried to fill the report created by 0.4.6 with 0.5.0. I'm not sure if this is the reason for your problem.

I think your report was compiled with 0.4.6, but you are trying to run it with 0.5.0.

Check your subreports too!

 

I hope it helps!
