Estou tentando fazer um relatório em java e criei esta classe:

import net.sf.jasperreports.engine.data.JRXmlDataSource;

import net.sf.jasperreports.engine.export.JRPdfExporter;

import net.sf.jasperreports.engine.*;

import java.util.HashMap;

public class Relatorio {

public static void main(String[] args) throws Exception {

              String reportFileName = "/addressbook.jasper";
              String outFileName = "/addressbook.pdf";
              String xmlFileName = "/addressbook.xml";
              String recordPath = "/Northwind/Customers";

              JRXmlDataSource jrxmlds = new JRXmlDataSource(xmlFileName,recordPath);

      HashMap hm = new HashMap();

      try
      {
          JasperPrint print = JasperFillManager.fillReport(
                      reportFileName,
                      hm,
                      jrxmlds);

          JRExporter exporter = new net.sf.jasperreports.engine.export.JRPdfExporter();

          exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,outFileName);
                  exporter.setParameter(JRExporterParameter.JASPER_PRINT,print);

                  exporter.exportReport();
                  System.out.println("Created file: " + outFileName);
      }
      catch (JRException e)
      {
          e.printStackTrace();
          System.exit(1);
      }
      catch (Exception e)
      {
          e.printStackTrace();
          System.exit(1);
      }

  }

}

ela compila corretamente mas quando executo ela apresenta a mensagem abaixo:

Este erro é porque a classe não encontra o arquivo addressbook.jasper

Se estiver no mesmo diretorio da classe nao precisa colocar a barra na frente

onde declara o arquivo

String reportFileName = "/addressbook.jasper";

Nosso código:

public class Relatorio {

public static void main(String[] args) throws Exception {

              String reportFileName = "addressbook.jasper";
              String outFileName = "addressbook.pdf";

      JRXmlDataSource jrxmlds = new JRXmlDataSource(new

BufferedInputStream(new
FileInputStream(“bd.xml”)),"/Northwind/Customers");

HashMap hm = new HashMap();

      try
      {
          JasperPrint print =

JasperFillManager.fillReport(reportFileName,hm,jrxmlds);

JRExporter exporter = new

net.sf.jasperreports.engine.export.JRPdfExporter();

exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,outFileName);
          exporter.setParameter(JRExporterParameter.JASPER_PRINT,print);

          exporter.exportReport();
          System.out.println("Created file: " + outFileName);
      }
      catch (JRException e)
