1.JavaBeanコード
public class UserBean {
private String name;
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}

<!DOCTYPE html>

<meta charset="UTF-8″>
<title>会員登録</title>
</head>
<body>
<form action="userReg.jsp" method="post">
<table>

<td><input type="submit" value="登録"></td>
</tr>
</table>
</form>

<% request.setCharacterEncoding(“UTF-8″);
<jsp:UserBean id="user" scope="page" class="com.ctn.kdf.UserBean"></jsp:UserBean>
<jsp:setProperty property="*" name="user" />
