error using JasperReport with Sun Studio Crea

2006-06-08 18:28

Hi,

 

I am a newbie using JasperReports v1.2.0 in a J2SE environment using Sun AS 8.

 

The .jasper file is created correctly and my .jrxml file displays fine in iReport-1.2.0

 

I need to create reports in Studio creator the Sun.

 

I tried many examples but I always end up with the same error msg and can't find a solution for it.

 

This is the error message:

 

 

net.sf.jasperreports.engine.JRException: Error loading expression class : testreport_1142608681187_139038

 

 

InputStream wfile = new FileInputStream(new File("c:/Program file/JasperSoft/iReport-1.2.2/reports/report.jrxml"));

JasperDesign design = JRXmlLoader.load(wfile);

JasperReport report = JasperCompileManager.compileReport(design);

 

JasperPrint print = JasperFillManager.fillReport(report,param, conn);

 

 

I have tried to change the java.policy of the JRE adding:

 

permission java.lang.RuntimePermission "createClassLoader";

in this file:

C:SunCreatorSunAppServer8domainscreatorconfigserver.policy (windows)

I put it in between grant { };

 

but even this doesn't work.

 

 

Has anyone had the same problem and maybe found a solution for it?

I would be very thankful if someone could point me in the right direction.
