入力フォームの値を保持したい

解決したいこと

今Webアプリを作っています。入力フォームに値を保持したいのですが、うまくいきません。
表以外はうまくいったのですが、表の中の入力フォームはうまく値を保持することができませんでした
ネットでも色々調べたのですが、そもそもtableを入力フォームにしている事例があまりなく困っています

発生している問題・エラー

1,2枚目で入力して投稿ボタンを押してエラーがあった場合1,2枚目で入力した値をそのままにしたいのですが3,4枚目のとおりうまくいってません。

自分で試したこと

入力フォームで受け取ったものをサーブレットのpostで"items"や"volumes"をListにいれてjspで出力したり
hashmapに入れてみたりpをjspで出力したりいろいろ試した結果サーブレットではなくjspがうまく書けていないのではないかと思っています。

サーブレット＋JSP(+JSTL)で表形式の入力をする場合は、以下の点に留意します。

同一名のパラメータを受け取るには、String[] value s= request.getParameterValues(パラメータ名) を用いる
送信するパラメータの長さにあわせて配列の長さを決めるか、初期長さを決めておかないとエラーになりやすい
JSTLは連想配列でも固定長の配列でも同じ記述で繰り返し表示ができる

例えばサーブレットは以下のように、値がない場合は初期配列10になるよう調整します。(getとpostで同じ実装ですが、特に変更内容が変わらないだけですので、メソッドの統合はしていません）

java
1import java.io.IOException;
2
3import javax.servlet.ServletException;
4import javax.servlet.annotation.WebServlet;
5import javax.servlet.http.HttpServlet;
6import javax.servlet.http.HttpServletRequest;
7import javax.servlet.http.HttpServletResponse;
8
9@WebServlet("/TableServlet")
10public class TableServlet extends HttpServlet {
11
12	final int SIZE = 10;
13
14	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
15
16		String[] items = convertBlank(request.getParameterValues("items"));
17		String[] volumes = convertBlank(request.getParameterValues("volumes"));
18		String[] units = convertBlank(request.getParameterValues("units"));
19
20		request.setAttribute("items", items);
21		request.setAttribute("volumes", volumes);
22		request.setAttribute("units", units);
23
24		request.getRequestDispatcher("tableInput.jsp").forward(request, response);
25	}
26
27	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
28		request.setCharacterEncoding("utf-8");
29
30		String[] items = convertBlank(request.getParameterValues("items"));
31		String[] volumes = convertBlank(request.getParameterValues("volumes"));
32		String[] units = convertBlank(request.getParameterValues("units"));
33
34		request.setAttribute("items", items);
35		request.setAttribute("volumes", volumes);
36		request.setAttribute("units", units);
37
38		request.getRequestDispatcher("tableInput.jsp").forward(request, response);
39	}
40
41	private String[] convertBlank(String[] values) {
42		if (values == null) {
43			return new String[SIZE];
44		}
45
46		return values;
47	}
48
49}
50

これを表形式で表示するJSPは、例えば以下のようになるでしょう。

jsp
1<%@ page language="java" contentType="text/html; charset=UTF-8"
2	pageEncoding="UTF-8"%>
3<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
4<!DOCTYPE html>
5<html>
6<head>
7<meta charset="UTF-8">
8<title>表形式の入出力</title>
9</head>
10<body>
11	<form method="POST" action="TableServlet">
12	<table>
13		<thead>
14			<tr>
15				<th>品番・品名</th>
16				<th>数量</th>
17				<th>単位</th>
18			</tr>
19		</thead>
20		<tbody>
21			<c:forEach var="i" begin="0" end="9">
22				<tr>
23					<td><input type="text" name="items" value="<c:out value='${items[i]}' />"></td>
24					<td><input type="text" name="volumes" value="<c:out value='${volumes[i]}' />" /></td>
25					<td><select name="units">
26							<option value="1" <c:if test="${'1' == units[i]}">SELECTED</c:if>>ｍ</option>
27							<option value="2" <c:if test="${'2' == units[i]}">SELECTED</c:if>>㎡</option>
28							<option value="3" <c:if test="${'3' == units[i]}">SELECTED</c:if>>式</option>
29							<option value="4" <c:if test="${'4' == units[i]}">SELECTED</c:if>>ケース</option>
30					</select>
31					</td>
32				</tr>
33			</c:forEach>
34		</tbody>
35	</table>
36	<input type="submit" value="送信">
37	</form>
38</body>
39</html>

リストボックスの箇所については、valueの値は表示するための文字列ではなく、何らかのコード値（ここでは上から1～4の数値を割り振った）にした方が実装しやすくなるかと思います。
