Hello,

I'm in the final stages of generating my pdf report. I have the .jasper and .jrprint created and when I try and export the .jrprint to pdf I get the following exception. Can someone explain what it means? Thanks

 

ExceptionConverter: java.lang.NullPointerException

Hi,

 

What version of JasperReports are you using and

how are you exporting to HTML?

Do you use the JasperExportManager?

 

Thank you,

Teodor

Hello,

 

I am exporting to pdf using the following code:

 

String printFile = JasperFillManager.fillReportToFile

("C:\test_1.jasper", null, new

JRBeanArrayDataSource( list.toArray() ) );

 

/**

* Export the .jrprint file to a .pdf

*/

JasperExportManager.exportReportToPdfFile

(printFile);

 

 

 

I have managed to fix the problem by including every jar that comes with jasperreports-1.0.1, but this is just a band-aid because there are several jars which i dont need.
