４．メインbean

$ cat databean.java
import java.util.*;

public class databean {
  private String layout;
  private Listsublist;

  public void setLayout(String layout) { this.layout = layout; }
  public String getLayout() { return(layout); }

  public void setSubList(Listsublist) { this.sublist = sublist; } 
  public List getSubList() { return(sublist); } 
}

５．サブbean

$ cat subbean.java
public class subbean {
  private String pack;

  public void setPack(String pack) { this.pack = pack; }
  public String getPack() { return(pack); }
}

６．サブbean1

$ cat subbean1.java
public class subbean1 extends subbean {
  private String apple;

  public void setApple(String apple) { this.apple = apple; }
  public String getApple() { return(apple); }
}

７．サブbean2

$ cat subbean2.java
public class subbean2 extends subbean {
  private String orange;
  private String value;

  public void setOrange(String orange) { this.orange = orange; }
  public String getOrange() { return(orange); }

  public void setValue(String value) { this.value = value; }
  public String getValue() { return(value); }

$ cat sample01.java
import java.util.*;
import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.engine.data.*;

public class sample01 {

   public static void main(String[] args) {
      databeanlist data = new databeanlist();
      ArrayListdataList = data.getdatabeanlist();

      JRBeanCollectionDataSource beanColDataSource =
            new JRBeanCollectionDataSource(dataList);

      try {
         Map parameters = new HashMap();
         JasperFillManager.fillReportToFile("sample01.jasper",
            "sample01.jrprint",parameters, beanColDataSource);
      } catch (JRException e) {
         e.printStackTrace();
      }
      System.out.println("Done filling!!! ...");
   }
}
