body: <p>I'm trying to compile a sample report using JaspeReport 5.6.0. in NetBeans 8.0.
  Using the following class code :</p>
  
  <pre><code>        package kinema.utility;
  
  import java.util.HashMap;
  import net.sf.jasperreports.engine.JREmptyDataSource;
  import net.sf.jasperreports.engine.JRException;
  import net.sf.jasperreports.engine.JasperCompileManager;
  import net.sf.jasperreports.engine.JasperFillManager;
  import net.sf.jasperreports.engine.JasperPrint;
  import net.sf.jasperreports.engine.JasperReport;
  import net.sf.jasperreports.view.JasperViewer;
  
  
  public class ChiamaReport {
  
   public ChiamaReport() {
  
  
      try {
  
  
         JasperReport jasperReport = JasperCompileManager.compileReport("c:\report1.jrxml");
          JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(), new JREmptyDataSource());
          JasperViewer jasperViewer = new JasperViewer(jasperPrint);
          jasperViewer.setVisible(true);
      } catch (JRException ex) {
      }
  
  }
  </code></pre>
