"AWT-EventQueue-0" Error

2006-07-10 09:01

Hi there,

I've been trying to get this error out of my way for a while now and finally I've to come to these forums for some help.

 

This is a simple program which generates a Jasper Report. The only information that report has is a Static Title Field.

 

 

jasperReport = (JasperReport) JRLoader.loadObject("./report/Quicktemp.jasper");

jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, jrds);

JasperExportManager.exportReportToPdfFile(jasperPrint,"./report/Quicktemp.pdf");

Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " +"./report/Quicktemp.pdf");

 

No parameters to pass, no fields to pass. jrds is an empty data source. The thing is that this perfectly executes in the IDE am using (JBuilder). But when I make an excutable JAR file and try to run it then I get the error:

 

Excpetion in thread "AWT-EventQueue-0" java.lang.ExceptionInInitializerError

Can anyone please help me with this error?

 

Thanks much :)
