Any suggestion??
Here's my coding:
<%@ page import="java.sql.*"%>
<%
String connectionURL = "jdbc:mysql://localhost:3306/example?user=root&password=password";
Connection connection = null;
Statement statement = null;
ResultSet rs = null;
%>
<html>
<body>

<%
Class.forName("com.mysql.jdbc.Driver").newInstance();
connection = DriverManager.getConnection(connectionURL,"","");
statement = connection.createStatement();
rs = statement.executeQuery("SELECT * FROM student");

while(rs.next()) {
out.println(rs.getString("name"));
}

rs.close();

%>

</body>
</html>
