Java - ถามเกี่ยวกับ JasperReport ครับ ถ้าต้องการ Input ข้อมูล โดยไม่ยุ่งกับ Database มีวิธีเขียนแบบไหนมั่งครับ ??

 private class R{
  private String name;
  private String addr;

  public R(String name, String addr) {
   super();
   this.name = name;
   this.addr = addr;
  }
  public String getName() {
   return name;
  }
  public void setName(String name) {
   this.name = name;
  }
  public String getAddr() {
   return addr;
  }
  public void setAddr(String addr) {
   this.addr = addr;
  }

 }

   List<R> list = new ArrayList<R>(5);

   Map parameters = new HashMap();
   list.add(new R("a1" ,"a2"));
   list.add(new R("b1" ,"b2"));
   list.add(new R("c1" ,"c2"));

JasperPrint print = JasperFillManager.fillReport( fileName, parameters, new JRBeanCollectionDataSource(list));
