jasper でレポート作成（帳票作成）

■帳票作成
１．bean

$ cat databean.java
public class databean {
  private String first_name ;

  public void setFirst_name(String name) { first_name = name; }
  public String getFirst_name() { return(first_name); }
}

2．bean生成

$ cat databean.java
public class databean {
  private String first_name ;

  public void setFirst_name(String name) { first_name = name; }
  public String getFirst_name() { return(first_name); }
}

3．帳票作成

import java.util.*;

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

class sample01 {
   @SuppressWarnings("unchecked")
   public static void main(String[] args) {
      databeanlist db = new databeanlist();
      ArrayList dblist = db.getdatabeanlist();

      JRBeanCollectionDataSource beanColDataSource =
      new JRBeanCollectionDataSource(dblist);

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

４．コンパイル

$ javac sample01.java
$ ls
databean.class  databeanlist.class  jrc.class  sample01.class   sample01.java
databean.java   databeanlist.java   jrc.java   sample01.jasper  sample01.jrxml

５。実行（.jrprint作成）

$ java sample01
databean.class      databeanlist.java  sample01.class   sample01.jrprint
databean.java       jrc.class          sample01.jasper  sample01.jrxml
databeanlist.class  jrc.java           sample01.java

６。印刷イメージ確認

$ java net.sf.jasperreports.view.JasperViewer test01.jrprint
