java.io.EOFException for CSV format

[manumtl]

Hello everyone, I am currently on JasperReports-0.6.1-project
And I try to run the example BarbecueApp
As an argument.
Tcsv-
Ftestss-

but when I run it. I have a

java.io.EOFException
    at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2230)
    at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2696)

    at com.hydroquebec.mac.ssep.ce.util.rapport.jasperreport.BarbecueApp.main(BarbecueApp.java:214)

 

 

but the code is simple

Code:

if (TASK_CSV.equals(taskName))            {File sourceFile = new File(fileName);                               //File sourceFile = new File(contextReportFile);                boolean creer = sourceFile.createNewFile();                if(!creer)                    creer = sourceFile.mkdir();                       JasperPrint jasperPrint = (JasperPrint)JRLoader.loadObject(sourceFile);                       File destFile = new File(sourceFile.getParent(), jasperPrint.getName() + ".csv");                               JRCsvExporter exporter = new JRCsvExporter();                               exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);                exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, destFile.toString());                               exporter.exportReport();}

that's not really enough to go on, post a little more and I might be able to help. Above all else, upgrade if possible. Gonna have a hard time getting support for a 5+ yr old version

Hello gertbeedfrobe, thank to get back to me. I m only try to run the sample BarbecueApp for the version JasperReports-0.6.1-project for a java application. 

 

I think my problem is in the argument

Tcsv-
Ftest

if I put a file name test

a got a message

ok I just read in this forum

For the PDF export task of the Barbecue sample you have to provide the serialiazed jasper print (.jrprint) file. This object/file is obtained by compiling and filling the report design (.jrxml).

 

thank.
