Export failure


Recommended Posts



I need to call iReport from an application. I wrote a java class to do so. The code works perfectly for a pdf export but fails for a docx (or rtf) export.

I just have this error text :

Exception in thread "main" java.lang.ClassCastException: java.lang.String

at net.sf.jasperreports.engine.export.JRRtfExporter.exportReport(JRRtfExporter.java:207)

at geneReportToolkit.ExportToRTF.getRTFReport(ExportToRTF.java:100)

at geneReportToolkit.ExportToRTF.main(ExportToRTF.java:41)



Here is the export part of the code



// Export to rtfString reportName="/tmp/myRtfReport.rtf";JRRtfExporter exporter = new JRRtfExporter();exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);exporter.setParameter(JRExporterParameter.OUTPUT_FILE, reportName);exporter.exportReport();

The code "exporter.setParameter(JRExporterParameter.OUTPUT_FILE, reportName);"

is setting the file to a parameter. If the file does not exist, it will throw classcast exception, as the code will be something like 

 destFile = (File)parameters.get(JRExporterParameter.OUTPUT_FILE);


here the values in the RExporterParameter.OUTPUT_FILE is cast to File.if myRtfReport.rtf does not exist

exception is thrown


hope this helps.

Thank you very much. It dit help a lot.

I change this line :

exporter.setParameter(JRExporterParameter.OUTPUT_FILE, reportName);


exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, reportName);

and now it works.
