You need to use the nameattribute in the form fields .
您需要name在表单字段中使用该属性。
<input type="text" name="email"></td>
The value of "email" can be retrieved in JSP as :
“email”的值可以在 JSP 中检索为：
String email = request.getParameter("email");
OR
或者
${param.email}
OR
或者
<c:out value="${param.email}"/> <%--(Using JSTL)--%>
Here are the complete listof attributes.
name = string #
名称 = 字符串 #
The name part of the name/value pair associated with this element for the purposes of form submission.
用于表单提交的与此元素关联的名称/值对的名称部分。

You should specify the input nameattribute. Try this,
您应该指定输入name属性。试试这个，
<form action="form.jsp" method="get">
<table cellspacing="5" border="0">
<tr>
<td align="right">Email:</td>
<td><input type="text" name="email"></td>
</tr>
<tr>
<td align="right">Password:</td>
<td><input type="text" name="password"></td>
</tr>
<tr>
<td></td>
<td><br><input type="submit" value="Submit"></td>
</tr>
</table>
</form>
