Log file trouble

[kovalensue]

hello guys,

i have made a .log file:

public class Start {

public static void main(String[] args) {


//Zápis do logu
String logFile = System.getProperty("java.io.tmpdir") + "adventure.log"; System.out.println(logFile);

.
.
.
GUI gui = new GUI();
gui.setVisible(true);
}

when i run a programme in output window shows this directory of logFile

C:\Users\VLASTN~1\AppData\Local\Temp\adventure.log

and now i want to put a button into my GUI and when you click on it then will show up a dialog window with logFile....:

private class OvladacLog implements ActionListener {
        private JDialog log;
        private JEditorPane logOutput;
        private String fileDirectory;


        @Override
        public void actionPerformed(ActionEvent e) {
            log = new JDialog();
            log.setTitle("Log");
            log.setModal(false);
            log.setVisible(true);
            logOutput = new JEditorPane();
            logOutput.setEditable(false);
            log.add(new JScrollPane(logOutput));
            URL fileDirectory = ???? 
            try {
                logOutput.setPage(fileDirectory);
            } catch (IOException exception) {
                JOptionPane.showMessageDialog(null,
                        "Log file not found",
                        "Loading failed",
                        JOptionPane.ERROR_MESSAGE);
            }
            log.setLocation(700, 200);
            log.setSize(400, 600);
        }

    }

So, my question is: How to get the .log file which i created in main method and put it into Dialog window??....thanks for help....

Read the contents of log file using BufferedReader and then add those contents to JTextArea.

See this code example for more help:

Unfortunately, that's not a statement that we can answer, and I doubt that you want us to re-write the tutorial. What specifically don't you understand? What have you tried that's not working?
