-------------------------------------------------------------게시판 테이블 생성
create table board(
   num number NOT NULL,
   writer varchar2(20) NOT NULL,
  email varchar2(30),
subject varchar2(50) NOT NULL,
passwd varchar2(10) NOT NULL,
reg_date date NOT NULL,
readcount number default 0,
ref number NOT NULL,
re_step number NOT NULL,
re_level number NOT NULL,
content varchar2(100) NOT NULL,
ip varchar2(20) NOT NULL,
PRIMARY KEY(num)
);

create sequence board_seq;

-------------------------------------------------------------BoardDataBean.java
package my.board;

import java.sql.Timestamp;

public class BoardDataBean {
private int num;
private String writer;
private String subject;
private String email;
private String content;
private String passwd;
private Timestamp reg_date;
private int readcount;
private String ip;
private int ref;
private int re_step;
private int re_level;

setter와 getter를 생성
}

------------------------------------------------------------------------호출순서
서버실행->*.do
(writeForm.do)

->ControllerAction
CommandPro.properties 파일 읽어옴

-> init()
my.action.WriteFormAction 생성 (CommandAction 구현)

-> doGet()
http://localhost:9090/mvc2bbs/writeForm.do

-> requestPro()
com= /mvc2bbs/writeForm.do -> WriteFormAction.java -> writeForm.jsp
