Multiple Pages in one JasperPrint

Sample Code:

DefaultTableModel dtm = new DefaultTableModel(new Object[0][3], new String[]{"Id","Name","Family"});
String[] fields= new String[3];    
boolean firstFlag=true;
JasperPrint jp1 =null;
JasperPrint jp2 =null;
for (int i=0 ; i<=pagesCount ; i++)
{
   fields[0]= "id";
   fields[1]= "name";
   fields[2]= "family";
   dtm.insertRow(0, fields); 
   try
   {
      Map params = new HashMap();                
      if (firstFlag)
      {
         jp1 = JasperFillManager.fillReport(getClass().getResourceAsStream(reportsource), params, new JRTableModelDataSource(dtm));                
         firstFlag=false;                            
      }else
      {
         jp2 = JasperFillManager.fillReport(getClass().getResourceAsStream(reportsource), params, new JRTableModelDataSource(dtm));
         jp1.addPage(jp2.getPages().get(0));
      }     
   }catch (Exception e) 
   {
      System.out.println(e.fillInStackTrace().getMessage());
   }
}
JasperViewer.viewReport(jp1,false);
