How to use mysql-connector-driver with jsp
<p>I need to create a login with JSP and so, I need to use <code>mysql-connector-java</code>.</p>

<p>I insert the file jar: <code>mysql-connector-java-5.1.38-bin.jar</code>  into <strong>WEB-INF/lib</strong></p>

<p>and I use this code into the jsp file:</p>

<pre><code>&lt;%@ 
        page import="java.sql.*"
    %&gt;

&lt;%
    String DRIVER = "com.mysql.jdbc.Driver";
    String URL_mioDB = "jdbc:mysql://localhost:3306/ditta";

    try
    {
       Class.forName(DRIVER);
    } 
    catch (ClassNotFoundException e) 
    {
       System.err.println("Driver not found" + e);
    } 

    Connection connessione = null;
    try
    {
       // apro la connesione verso il database.
       connessione = DriverManager.getConnection(URL_mioDB,"root","");
    } 
    catch (Exception e)
    {
       System.err.println("Error during connection with db : " + e);
    } 

    String mail="",pass="",send="",query="";

    try
    {
        mail=request.getParameter("email");
        pass=request.getParameter("password");
        send=request.getParameter("send");

        out.println("&lt;FORM name='F1' method='post' action='login.jsp'&gt;");
            out.println("Email: &lt;INPUT type='text' name='email' value='' placeholder='mariorossi@gmail.com'&gt;&lt;BR&gt;&lt;BR&gt;");
            out.println("Password: &lt;INPUT type='password' name='password' value=''&gt;&lt;BR&gt;&lt;BR&gt;");
            out.println("&lt;INPUT type='submit' name='send' value='Invia'&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;INPUT type='reset' name='reset' value='Reset'&gt;");
        out.println("&lt;/FORM&gt;");
    }
    catch (Exception e)
    {
       System.err.println(e);  
    } 

    if(send!=null &amp;&amp; mail!="" &amp;&amp; pass!="")
    {
        query="SELECT * FROM dipendenti WHERE email="+ mail + " AND password=" + pass + "";

        Statement statement = connessione.createStatement();
        ResultSet resultSet = statement.executeQuery(query);
        ResultSetMetaData rsmd = resultSet.getMetaData();

        for(int i=0;i&lt;=rsmd.getColumnCount();i++)
        {
            out.println(resultSet.getString(i));
            }
    }

%&gt;
</code></pre>

<p>after that, When I click on the send button the page give me this error:</p>
