Listener for changes in file

Hi
I am trying to solve a problem that needs me to display server logs to client developer using an applet.
I've written a logserver that reads the logfile and spits the output to the socket where my applet is connected to and reading for new data.
The problem I am facing is that I don't know how to tell the logserver that there is new stuff in the logfile that needs to be read and send to the socket so that Applet can read it and display it.
Can I register some kind of listner to this log file and set up a callback that then reads this file?
Thanks
Desi

Create a Runnable. Read the time stamp of the file using getLastModified. The thread checks after some time the new time stamp.
If value has changed just trigger an event.
Hope that helps.

  • How do I listen for changes in a container's components?

    I have a JScrollPane that contains a JTextPane. I want any Container that can possibly contain my JScrollPane to be able to listen for changes in the JTextPane's Document.
    For example, at the moment I'm using a JTabbedPane to hold a number of my JScrollPanes and I want to alter the tab title when any associated JScrollPane-JTextPane-Document is updated.
    Any suggestions on how best to handle this?

    I would use a controller object that manages all your gui components (tabs, scrolls, documents, text panes). Your controller object can register as a listener to the appropriate component, and when it changes, update the title of a tab (or do whatever else) as appropriate.
    Never put business logic like this stuff inside the actual gui components. Create, layout, etc. all the gui components (and related components like Document) from another controller like object instead. It makes handling the various listener stuff like this much easier. Read up on MVC (model view controller) stuff for more info.
    As for the actual mechanics, you could get the document that is used in the JTextPane and register as a DocumentListener. As a document listener, you get notified of all changes that are made to that document.

  • How do I listen for change in the global position of a Node

    Hi there,
    I want to create a Wire/Connection node between two scene nodes. I want this Wire node to be updated when one of the nodes is moving. In the common scenario I would listen for change events in the target nodes position and update the Wire :
    targetNode1.translateXProperty().addListener(new ChangeListener<Number>() {
    public void changed(ObservableValue value, Number oldValue, Number newValue) {             
    wire.setStartX(targetNode1.getTranslateX());
    wire.setStartX(targetNode1.getTranslateY());
    wire.setEndX(targetNode2.getTranslateX());
    wire.setEndY(targetNode2.getTranslateY());
    The problem is that the target nodes are children of another container nodes(that are actually moving). So listening for change events in the translate properties of the target nodes does not work(their parent nodes are actually moving)
    Is there way to listent for change in the global position of the target nodes relative to the Scene?

    It sounds very similar to a problem I posted about earlier...
    How to implement a UI similar to a UML Diagram with connections?
    I ended up making my own special bounds property, that updates when the parent's special bounds property changes.
    I also had to listen to the parentProperty change event to add/remove my listener on the parent node.
    All in all, a pain in the butt. There should be an easier way.
    The shortcoming of the solution is that all the nodes in the hierarchy must have my special bounds property implemented (ie. they're all classes under my codebase such that I can implement it), which for the moment is true... I'd like a cleaner solution however.

    what can i do for change CMYK file for RGB file, in Photoshop?
    I have to upload BEHANCE.. so please teach me, hurry.

    In Photoshop, you just change the image mode in the Image > Mode menu. Pretty basic stuff. You might want to spend some time reading some manuals to get the most of all the money you're paying.

  • Listening for Changes to JTextArea

    I am writing a program that listens for changes to the contents of a JTextArea to obtain input for its execution. But I have implemented DocumentListener, PropertyChangeListener to listen for changes to the JTextArea for deriving input without success. Please could anyone advice on what to do.
    My code is below.
       myListener implements DocumentListener{
       JTextArea txt = new JTextArea();
       txt.getDocument().addDocumentListener(this);

  • SWF panel listener for changed selection

    In short, my question is as follows. Is it possible to create a listener which
    detects when the current selection in the Flash authoring tool has changed,
    and informs my SWF panel? This does not have to be a listener per se,
    it can be some hand-crafted process which consumes some reasonable amount of processor time.
    I describe my question more precisely below.
    Suppose that I want to create an SWF extension panel for Flash (in Flash or Flex),
    and I would like the panel to display a property of the object currently selected on scene
    in the Flash IDE -- like the instance name of the object (if it exists).
    I can use JSFL to detect the instance name of the selected object, and pass the string to the
    SWF panel using call(), for instance. The problem is that I don't know how
    to detect that the user has selected the object, or that the selection has changed.
    Ideally, I would like to add an event listener that listens for such an action in the flash authoring tool.
    However, using JSFL, this does not seem to be possible (I can only listen to events such as frame changed
    or layer changed, but not selection changed).
    I tried the following solutions:
    1. Periodically check in JSFL whether the current selection has changed.
    The problem is that in JSFL, there is no sleep function, or anything alike. The javascript
    methods setInterval and setTimeout do not work in JSFL. Therefore, in order to periodically check for changes,
    one must actively loop. This is extremely resource-consuming -- in fact, it hangs the flash IDE.
    2. The periodic check can be triggered by the SWF panel itself. In actionscript, I can use setInterval to periodically
    invoke the selection update function via JSFL. I have set the interval to 400 milliseconds, which gives a reasonably quick
    reaction to changes. However, the functionality I want to implement is in fact more complicated than just retrieving the
    instance name of the selected object. As a consequence, performing this operation every 400 milliseconds still consumes
    too much processor time (the flash IDE consumes 30% of my processor time, even if the user doesn't do anything).
    Therefore, I still would like to find a solution which does not use the processor when the user does not do anything in the Flash IDE.

    I'm trying to do the same thing. Did you find a solution?

  • Listen for change in JTextField

    I would like to write an event listener to listen for any changes made to a JTextField. Normally I would think that keyListeners would do the trick except that the contents of this field can be altered by the application itself, and I would like to trap those changes too.
    Does anyone know of an event listener that listens for any changes made in the text of a JTextField, regardless of how those changes are made?

    use DocumentListener

  • Is there any event listener for changing the selection of layer?

    Hi all,
    I am looking into an event listener which fires on changing the selection of layer. I found 'Select' event listener which fires on selecting the different object.
    Actually the problem with Select event listener is that when we select an object and move it and deselect it by clicking on the document, event fires on the selection of that object. But if we again select the same object and move it, no event is fired at that time.
    Is there any workaround of this? So that the event is fired every time when we select the same object.
    Please help me on this..
    Regards,
    VG.

    Thanks for the reply..
    Actually I want the same behaviour as in illustrator i.e
    - Select a layer. (Notifier calls the listener)
    - Move it.
    - Click on the document.
    - Again select the same layer. (Notifier calls the listener again)
    - Move it.
    But in photoshop,
    - Select a layer. (Notifier calls the listener)
    - Move it.
    - Click on the document.
    - Again select the same layer. (Notifier doesnot calls the listener again as the layer is already selected in panel as you explained.)
    - Move it.
    Is there any way to get the same behaviour of illustrator in photoshop?

  • Listening for change events on a JTable

    Hi
    me = Java newbie!
    Well I've been building an app to read EXIF data from JPEG files using the imageio API and Swing. Learning both along the way.
    Stumbling block is that I am outputting the EXIF data into a JTable, inside a JScrollPane. These 2 components then become associated with a JInternalFrame container of the class MyInternalFrame.
    Works!
    Next job is to enable user to select a row in the table which then displays the image file.
    I know I can use ListSelectionEvent to detect a row selection and that 2 events are fired.
    I put some code into MyInternalFrame class to register a ListSelectionEvent, but I can't see how to reference MyInternalFrame from within this code....see below:
    package EXIFReader;
    import java.io.File;
    import java.io.FilenameFilter;
    import javax.swing.JInternalFrame;
    import javax.swing.JScrollPane;
    import javax.swing.JTable;
    import javax.swing.ListSelectionModel;
    import javax.swing.event.ListSelectionEvent;
    import javax.swing.event.ListSelectionListener;
    //This class constructs a table and displays it in a JInternalFrame
    public class MyInternalFrame extends JInternalFrame {
    static int openFrameCount = 0;
    static final int xOffset = 30, yOffset = 30;
    File file;
    File[] directoryMembers = null;
    public MyInternalFrame(File aFile) { //aFile rererences a directory containing jpeg files//
    super(null,
    true, //resizable
    true, //closable
    true, //maximizable
    true);//iconifiable
    file = aFile;
    //Set the window's location.
    this.setLocation(xOffset*openFrameCount, yOffset*openFrameCount);
    FilenameFilter filter = new FilenameFilter() {
    public boolean accept(File dir, String name) {
    return name.endsWith(".jpg");}};//Filter out any files in the directory that ain't jpegs
    directoryMembers = file.listFiles(filter);
    int i = 0;
    String[][] tableData= new String [directoryMembers.length][5];
    String[]headers = new String[]{"File Name","Date Taken",
    "F-Number","Exposure",
    "Flash Settings"};
    for (File dirfile: directoryMembers)
    try {
    if(dirfile!=null){
    tableData[i] = new ExifReader(dirfile).getEXIFData();//populate the table with jpeg file names
    i++;}}
    catch (Exception ex) {
    System.out.print("Error" + ex);
    if (tableData[0] != null){
    final JTable myTable = new JTable(tableData,headers);
    this.setSize(900,(50+(directoryMembers.length)*19));
    myTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
    this.getContentPane().add(new JScrollPane(myTable),"Center");//add the JTable and JScrollPanel to this MyInternal Frame and display it! - cool it works!
    ListSelectionModel myLSM = myTable.getSelectionModel();
    myLSM.addListSelectionListener(new ListSelectionListener() {
    public void valueChanged(ListSelectionEvent le) {
    int[] rows = myTable.getSelectedRows();//want to respond to selections and then display the image as a JInternalFrame but got confused about references from within this listener - need help!
    Any gentle nudges?!
    P
    I can respond to these events using a JFrame, but how can I display the image in a JInternalFrame?

  • JTextfield  listening for changes from other class

    Hi,
    Assuming I have a Jtextfield in one of the class1 extend Jframe,
    how do I update the jtextfield so that it could up make accessible by other class and continuously updated to reflect the input for value rom another class2.
    In other words very much similar to the observable model view concept
    class 1 may be look like
    private void initComponents() {
    jTextField1 = new javax.swing.JTextField();
    jButton1 = new javax.swing.JButton();
    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
    jTextField1.setEditable(false);
    class 2 may be look similar to the following
    public void out_1(){
    setStop1("N");
    for (int i=1;i<100;i++){
    class_1.getJTextField1().setText(String.valueOf(i)); // System.out.println(i);
    setOuti(i);
    setStop1("N");

    HI,
    I have attempted with the following coding , test 1 the source display generated using Netbeans GUI , t est2 the worker code ,and mybean the bean , so far nothing seems to work .
    I have not try the threaded swing concept as I am not familar with the concurrency but i am not sure whether propertylistener will do the job or not
    In summary , list of method employed are :
    binding the jtextfield1 to a bean,
    jtextfield add document listener ,
    Coding objective
    1. Test 1 defined jtexfield1 and jbutton
    2 Jbutton added actionlistener , where upon click,
    Execute Test 2 which will assign a series of integer to the bean , own setters & getters, Output is achieved via Test 1 jtextfield1 supposingly to display all the running number from 1 to 99 continuously until the test2 out_1 method finished the execution
    Anyone could provide the assistance .

  • The 2 year old fix for changing temp files is no longer valid, I need to change the temp file location in the latest firefox.

    In 3.6.3 I'm unable to find the parent cache to change where the temp files are located. I have an SSD drive, and I need to get the temp file off, and onto my platter drive. I have read the previous fix of about:config and changing the parent cache location, but it no longer seems to be there. I'm unable to locate anything relating to my SSD drive location in about:config.
    == User Agent ==
    Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.70 Safari/533.4

    Unfortunately, it appears that what I wrote about not being able to find the location IN about:config of the cache to change it from my C: drive to a different location, was mildly misunderstood that I didn't know how to get into about:config.
    The location of browser.cache.disk.parent_directory does not currently exist in 3.6.3. I'm assuming it's under a different location. Also using the simple string of "cache" lists several options, but none of them appear to be where firefox is currently dumping the temp files onto my C:
    I merely need to know how to switch the temp file location from 1 drive, to another. Not downloads, the temp file.

  • Is it mandatory for changing conf files for weblogic 10.1.2 to 10.3.5

    Hi Whom it may concern,
    we are going to version changing from weblogic10g to 10.3.5,is it mandatory to change the configuration files like application-client.xml,orion-ejb-jar.xml,orion-application-client.xm to weblogic-ejb-jar.xmll,please let me know.
    Thanks in advance.
    Regards,
    Venkatesh

    Hi Venkatesh,
    WebLogic Server will not be able to understand ,orion-ejb-jar.xml, orion-application-client.xml deployment descriptors.
    I believe it is a application which you have deployed on Oc4j Container.
    You need to migrate your application using the Smart upgrade tool.
    The Smart upgrade tool helps you to migrate the application and generates the necessary weblogic specific deployment descriptors and also suggests you the configuration changes by reading your oc4j configurations, to be made compatible and deployable on Weblogic environment.
    Please check the below doc.
    http://docs.oracle.com/cd/E16764_01/doc.1111/e15878/intro.htm
    Hope this helps!!
    Thanks,

  • Way to listen for change in JTable cell?

    I am having troubles trying to catch a key event while the user is entering text inside a given JTable cell (x/y location). The JTable only seems to manage String objects in it's cells so I can't place a JTextField in there with a KeyListener on it.
    Currently, I can only get control of the application once the user has left the cell they are editing.
    Does anyone have an example of a JTable 'cell KeyListener' scenario? At this point I want to see if I can print 'hello world' each time I type a character within a cell. Then I'll go from there....

    If you want to know when the contents of a cell have been updated you should use a TableModelListener.
    If you want to know when a character is added/removed from the cell editor then you need to first understand how this works with a simple text field.
    Typically you would use a DocumentListener to receive notifies of a change to the text field. However, within the DocumentEvent you wouldn't be able to change the text field as this notification comes after the text field has already been updated.
    If you need to ability to intercept changes to the text field before they happen, then you would need to use a DocumentFilter. An example of using a DocumentFilter is given in the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/generaltext.html#filter]Text Component Features.
    Once you get your regular text field working the way you want, the next step to create a DefaultCellEditor using this JTextField and use this editor in your JTable. The above tutorial also has a section on using editors in a table.
