Here is all the code from my register.jsp file
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>
<html>
<head>
<title>register</title>
</head>
<body>
<form action="register.jsp" method="post">
account:
<input type="text" name="user"></input><br>
password :
<input type="password" name="password"></input><br>
<input type="submit" name = "submit" value = "Submit"></input>
<input type="reset" name = "reset" value = "Reset"></input>
</form>
</body>
</html>
<c:set var="user" value = ${param.user } scope = request></c:set>
<c:set var="password" value = ${param.password } scope = request></c:set>
<sql:setDataSource driver="oracle.jdbc.driver.OracleDriver" user="scott" password="669193"
url = "jdbc:oracle:thin:@//localhost:1521/orcl"/>
<sql:query var="query" sql = "select * from users where user =? and password = ?">
<sql:param value = ${user }></sql:param>
<sql:param value = ${password }></sql:param>
</sql:query>
<c:choose>
<c:when test="${!empty query.rows}">
<jsp:forward page="Hello.jsp"></jsp:forward>
</c:when>
</c:choose>
当我打开它时，浏览器显示此错误 HTTP Status 500
任何帮助真的很感激:)谢谢！

你可以发布整个堆栈跟踪吗？另外，为什么要在视图（JSP）中嵌入数据库连接逻辑？他们应该在控制器的某个地方 .
