jsp "unable to compile" and "cannot be resolved to a type"

I have a jsp file that imports from my package folder inside my classes directory. When I try to use it, i get the "Unable to compile" and "cannot be resolved to a type" errors. Here are my code.

<%@ page language="java" import="cs5530.*" %>
<html>
<head>
<script type="text/javascript">
function showInvalid()
{
    document.getElementById("invalid").style.display = 'block';
    document.getElementById("loginForm").reset();
}
</script>
</head>
<body>
<p>Welcome to FlixNet. Sign In</p>
<form name="loginForm" method="post" action="index.jsp">
    User Name: <input type="text" name="username"><br>
    Password: <input type="Password" name="password"><br>
    <input type="submit" value="Submit">
    <div id="invalid" style="display:none">
        <p>Invalid username or password</p>
    </div>
</form>
<%
Connector con = new Connector();
con.closeConnection();
%>
</body>
</html>

this is the error

org.apache.jasper.JasperException: Unable to compile class for JSP:

    javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

this is my file structure

public_html
    index.jsp
    |WEB-INF
        |classes
             mysql.jar
            |cs5530
                Connector.java
                Connector.class
                other java and class files.

my Connector class is under the package cs5530 so that isn't the issue. The connector class is a simple db connector class that I have tested and it works.
