No Class does exists?

2005-03-11 10:47

Hi! I ve designed with "iReport" and compiled locally, on my PC, a jasperreport file (*.jrxml). It all works fine. But when I try to do the same on my webapp server (SAP Enterprise Portal) I get this mess:

Could anyone please help me?!

 

Here s the code I m using:

 

 

/* Crea el Informe y lo visualiza */

public void creaInforme() throws JRException, Exception{

 

try{

/* HashMap de los par metros utilizados en el informe */

Map parameters = new HashMap();

//parameters.put("imagePath", "C:\tmp\promocion.jpg");

 

// Compila el dise o

JasperCompileManager.compileReportToFile("C:/tmp/prueba.jrxml", "C:/tmp/prueba.jasper");

 

// Conexi n con la Base de Datos vac a

JREmptyDataSource ds = new JREmptyDataSource();

 

// Pasa los datos al informe y salva diretamente en formato PDF. Sin necesidad de archivo .jrprint

JasperRunManager.runReportToPdfFile("C:/tmp/promo.jasper", parameters, ds);

}

catch(Exception e){

throw e;

}

}

 

Thanks:)

JasperCompileManager.compileReportToFile("C:/tmp/prueba.jrxml", "C:/tmp/prueba.jasper");

 

Why don't you use pre-compiled reports?

Thanks Vinod, that s a good idea.I think you mean I should use directly the compiled jasper file that iReports brings out when a report is executed.

it seems you don't have all the necessary libs in you class path... try putting all the stuff in the lib folder for iReport in your web app's WEB-INF/lib... (not all the jars may be necessary, depends on what you do with your reports/app
