    <p>I am getting an error that says "<strong>cannot refer to a non-final variable inside an inner class defined in a different method</strong>"</p> <p>This is happening when I am trying to set up my timer referencing an action listener that I have constructed! This constructor simply displays a label and the timers desired effect is to run the action listener for 10 seconds but I can't get past this error. The code below shows he action listener and where he issue is occurring. I have put stars around the problematic areas. Thanks</p> <pre><code>**ActionListener actListner = new ActionListener() { public void actionPerformed(ActionEvent event) { lblgreenImage.setBounds(150,410,50,40); repaint(); } };** btnEnter.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent ae) { String username = txtUserName.getText(); String accessCode = txtPin.getText(); String dataSourceName = "securitysystem"; String dbUrl = "jdbc:odbc:" + dataSourceName; try{ //Type of connection driver used Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //Connection variable or object param: dbPath, userName, password Connection con = DriverManager.getConnection(dbUrl, "", ""); Statement statement = con.createStatement(); ResultSet rs = statement.executeQuery("select username, pin from securitysystem.employee where username = '" + username + "' and pin = '" + accessCode + "'"); boolean nomatches=true; while(rs.next()) { String checkrs = rs.getString("username"); String checkPin = rs.getString("Pin"); if (username.equals(checkrs)) { if (accessCode.equals(checkPin)) { **Timer timer = new Timer(500, actListner);** **timer.start();** </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
