  - Referencing the base methodI am creating a new custom JTextField object. I am overwriting my
    existing getText() method inside of it. The problem I am having is I
    don't know to get the text from the actual text field while I'm in my
    new getText() method. I tried casting my object but that didn't work.
    so my overall code looked something like this:
    
    public Class CustJTextField extends JTextField {
    
    private int length;
    
    CustJTextField(int length) {
    this.length = length
    }
    
    public String getText() {
    String text = ((JtextField)this).getText()
    if (text.length() > length) {
    return null;
    }
    return text
    }
    }
    
    Thats a much simpler form of what I'm coding, but you should be able to
    get the idea. Unfortunately calling the getText method with in my
    custom GetText method, ends up with a stack overflow error. Is there
    some way to reference the base method? Thanks for any help you guys
    can provide

  - JMF videoHi
    
    I'm building a multimedia CDROM using Java and JMF for playing video,
    audio, etc. on Windows only. I have an interesting problem and am
    stuck as to why it's happening and how to resolve it.
    
    Basically, everything is cool on my XP machine. But when I run the
    software on earlier Windows (95/8/ME/NT) the video won't play, and I
    get an error (not an exception) dumped to the console window saying
    that a player cannot be created for the video.
    
    Now I can understand JMF not being able to support certain video
    formats, but why does it work on XP but not on the others? I'm using
    the same JRE and JMF libraries on all machines, how can this be? Any
    ideas or suggestions?
    
    A couple of other related questions:
    
    - if I have to convert the video to a more 'common' format, does
    anyone know of any good (and free!) video conversion tools? I've had
    a nose round and found WinMPEG, it works for converting AVI to MPEG
    but don't seem to like converting the MPEGs I'm using to any other
    format.
    
    - the error I get from JMF is dumped to the console, why doesn't it
    throw an exception to the standard error stream? can I make it? stupid
    JMF!
    
    cheers for any ideas

  - javac doesn't find my anonymous classesI'm sorry of this question has been posed and answered many times before.
    But I have avoided using the "package" statement because of this.
    
    Most of my classes have no "package" statement, and their class files are
    stored in my current directory. Using "javac abc.java" works just fine.
    
    But some of my classes *do* have "package" statements. I try to compile
    them with "javac -d . def.java" so that the class file will be stored in a
    directory structure.
    
    But def.java refers to some anonymous classes whose class files are stored
    in the current directory. The "javac -d . def.java" can't find these
    classes. Why not?
    
    My classpath is ".;c:\Sub\Java\JRE", which works fine for my anonymous
    classes.

  - exception reportHi
    When my java application throw an exception, it will connect to
    MySQL, dump the exception to it. My java software is open source, so i
    scare everyone will know my mysql password because the password is
    inside the code.
    I can pack the class that connect to mysql to another jar, and don't
    release this piece of source code, but this is not open source and not
    what i want. Any other way?

  - A Business Case for Commons Daemon on FreeBSDGood Day,
    
    I have been working lately with ApacheDS LDAP server and am very impressed
    with its design and extensibility. Since it is written in pure Java, it
    makes Java geeks like myself quite happy.
    
    I would love to get it running on FreeBSD but unfortunately, it will not
    work without a service framework and therefore will not work on FreeBSD :'(
    The ApacheDS team has suggested getting a jsvc port for FreeBSD in order to
    port over ApacheDS. See Link to post:
    http://mail-archives.apache.org/mod_mbox/directory-users/200703.mbox/%email***@***.com%3e
    
    Having Commons Daemon would allow ApacheDS and solutions for Enterprise Java
    applications to the FreeBSD platform in a way that they are available
    already on Linux. At present, my only options are Linux (hmmm...) or Window
    (ack!).
    
    Please let me know how I can help get this port rolling again or help to
    expand this business case so we can justify getting this important project
    rolling again. I would be quite happy to help in being a tester.
    
    Thanks for your time and interest!

  - Java design question: Loosely coupled data extractionOk, so I have a rather complex object hierarchy performing a bunch of
    calculations and data manipulations. The hierarchy is populated using
    the builder pattern, which worked nice for abstracting away database and
    other data fetch mechanisms.
    Now time has come to extracting some data from the hierarchy, a report
    if you will. I would love to do this in the same loosely coupled way
    rather than implementing tree walking logic directly into the nodes of
    the hierarchy. My first though was the visitor pattern, as I guess it
    would allow me to hook ANY reporting/extracting mechanism up. Does this
    sound like a good idea? Are there alternatives you would suggest?
    
    Thanks in advance,
    Casper

    Oh man, Joan compared the communication between spouses with the
    communication between an employee and an employer in the software
    industry. I think this is not so difficult to understand!

  - how to populate the tomcat http request with account nameWe have a Tomcat application in which each request is routed via IIS
    (isapi-redirect)
    
    IIS populates a parameter with the
    active directory account name.
    
    This is then available in Tomcat to authenticate via a call
    to Active Directory.
    
    Without the account name I cannot see how we can authenticate.
    
    I am hoping someone can suggest an alternative way to providing
    the account name without using IIS?
    
    I have seen 3rd party products that support single sign on such as
    Vintela
    but these would appear to depend on the account name being
    provided in the request.

  - Hibernate and Date objectsHi everyone,
    
    I'm having a frustrating time working with Date objects and Hibernate
    with an Oracle database.
    
    I have a Patient class containing a Date field (java.util.Date)

java-programmer, [iText] template or watermark Hi,

I remember that with iText it is possible to use an existing PDF
document als template or "background image" for a new PDF document. IIRC
it could be done using some watermark- or template-functions?
(Unfortunately, the old documentation has ben abandoned...)

Anyway, I've got a document, and I could add a template to its
PdfContentByte. Furthermore, I have a PDFReader with which I've read the
existing document. But I don't know, how to get a template from the reader.

Or can this only be solved in a completely differnt way?

Ciao,
Ingo

  - implicit <? super T> when an array is a parameter in a generic methodi'm making some adjustments to previous code to utilize generics in java
    1.5 or 5.0 or whatever it is called. something seems inconsistent,
    though:
    let us say i have a method that operates on two collections:
    
    public <T> void testMethod(Collection<T> c1, Collection<T> c2){...}
    
    if i call this method with the following line, a compile-time error
    occurs:
    testMethod(new HashSet<Integer>(), new HashSet<Number>());
    
    and rightly so. in this case T != T (i.e. Integer != Number).
    
    the method would have to be rewritten to:
    
    public <T> void testMethod(Collection<T> c1, Collection<? super T>
    c2){...}
    and this indeed works. this is fine and quite logical.
    
    now the problem. let us assume i have a method that copies elements
    from an array into a collection:
    public <T> void testMethod(T[] a, Collection<T> c){...}
    
    suddenly i'm allowed to call this method with T != T, as in:
    
    testMethod(new Integer[100], new HashSet<Number>());
    
    the official word from sun is: "it will generally infer the most
    specific type argument that will make the call type-correct." apparently this
    line is only in reference to arrays (although they don't mention that).
    so when this "inferring" occurs, is there basically a re-writing going
    on the background that equates to changing the function to:
    public <T> void testMethod(T[] a, Collection<? super T> c){...}
    
    ?
    
    i guess the true root of the question is, which of the parameters (and
    indeed there may be many) will be going through the inferring process?
    there must be at least one "baseline" argument type parameter in calls
    like these that remains fixed (i.e. cannot go through an inferring
    process), because otherwise every type argument could just be inferred to be
    Object, making all calls legit and ruining the advantage of generics.
    wow, that may have been a bit confusing, but if anyone would point me to
    a general good source on java's version of generics (not sun's
    documents, as i've already tried to read those and they don't clear up this
    confusion at all), it would be greatly appreciated.
    thanks,

    Any suggestions?

    after some research in the bug database i found that this is a
    known bug with the print margins.
    
    http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6263423
    
    It seems that it doesnt matter whether one uses the native page
    setup dialog (PrinterJob.pageDialog(PageFormat)) or whether
    one uses the cross-platform Java page setup dialog
    (PrinterJob.pageDialog(PrintRequestAttributeSet)).
    
    Now i dont use a page setup dialog anymore, and use fix margins.
    :)
    
    regards

  - squeezing the use of memoryHi,
    Qick question about the use of int Vs. the use of short,char,byte
    in 'for' loops. Will it affect the memory utilization/performance at all ?
    If yes, to what extent, especially considering a program which uses
    looping extensively and doesn't need the entire 'int' range.
    Generally people just go ahead and use 'int' in loops...
    Awaiting your thoughts,
    Asif

  - SwingUtilities.getRoot() in a javax.swing.ActionAfter reading
    http://www.exampledepot.com/egs/javax.swing/frame_FrameFind.html
    
    I wrote a small test program in which I found that
    SwingUtilities.getRoot() returns null. getRoot() works well for me in
    other programs when I feed it a container (e.g. JPanel).
    
    What am I doing wrong? Cannot SwingUtilities trace the JFrame to which
    the JMenuItems are ultimately attached? Why not?

    SwingUtilities.invokeLater(new Runnable() {
    public void run() {
    new EnumAction();
    }
    });
    }
    
    EnumAction() {
    JMenu m = new JMenu("Menu");
    for (Command c : Command.values())
    m.add(new JMenuItem(c.action));
    JMenuBar mb = new JMenuBar();
    mb.add(m);

  - void method? Hello,
    I am not sure were to put the return, i want to return the sum of the 3
    digits, but it gives me an error becouse, it expect a void method

    }
    //method declaration
    public static int Sumdigits(long n){
    
    int num2 = (int)n % 10;
    int num1 = (int)n / 10;
    int num0 = (int)num1 % 10;
    int num100 = (int)n / 100;
    return
    System.out.println("de sum is" +num2+ "+" + num0 + "+" +num100);

  - Getting value of variable from Thread to main classI have a problem, with getting value of a variable that is set in
    thread. I start the Thread in a main class, thread gets the value from
    server and sets it as static variable. After starting the thread I try
    to print the value of " threadObjetc.staticvariable " but every time
    it has a null value. I suppose that the reason for that is that thread
    works in a background and functions of main class continues anyway. If
    someone had a similar problem and could help me to avoid it I would be
    gratefull for help, Thanks

  - Binomial Simulation-----BEGIN PGP SIGNED MESSAGE-----
    Hash: SHA1
    
    I'm taking a class in Evolutionary Computation. I just turned in an
    assignment that implements a simple genetic algorithm based on bit
    strings. For mutation I simply check each bit in the population and
    flip it with some constant probability. For a population of 10,000
    individuals of 100 bits that means that I have to execute the method
    Random.nextDouble() 1,000,000 times. I thought about this a bit and I
    could do the same operation by getting a single value from a binomial
    distribution and then selecting that number of bits at random. This
    would require far fewer operations that the current brute force method.
    For real problems this might not matter that much since mutation would
    take a small percentage of the time spent in the algorithm, but for my
    test problems mutation is the biggest contributor to run time.
    
    So, now to the question. Is there an open source implementation of
    nextBinomial() out there somewhere? I did a quick search of the web and
    didn't find one. I could implement my own, but it probably wouldn't be
    as fast as a widely used open source implementation and I don't want to
    spend the time on something that is really a library function if I don't
    have to.
    
    Note that I'm not trying to cheat here. If I end up using it in an
    assignment I will credit the author and the prof won't mind. This is a
    graduate course.
    
    Thank you.

  - synchronized confusion!hi all!
    If a method is synchronized like this:
    public synchronized void broadcast (String message) {
    
    I have like 10 threads calling the broadcast method.
    What happens to all threads calling this method?
    Does the threads halt/wait and line up in a qeueue??
    Is it like when one use the Wait-notify system or what.
    Does the threads stop what they are doing when they
    try to get access to the synchronized method and the method
    is locked.
    
    I know that when I use the wait() it will put
    thread's in the Wait mode. I can then do a notify/all
    and the waiting threds will continue. This is easy to
    understand. But the synchronized is not like that I guess
    
    Hope you understand what I mean!

  - Applet Issues!!Hey, Im Attempting to create an applet that will open a connection to my
    application server, the application server WILL be on the same machine
    that the applet will be loaded from, i.e. the app server is on the same
    machine as the web server. here is my code (sorry for the bad standards)
    
    public class ClientConference extends Applet {
    
    private ObjectOutputStream output;
    private ObjectInputStream input;
    private String message = "";
    private String chatServer;
    private Socket client;
    
    //----------------------------------------------------------------------//
    
    public ClientConference( String host ) {
    chatServer = host;
    ClientConference application;
    application = new ClientConference( "149.153.130.2" );
    application.runClient();
    }
    
    //----------------------------------------------------------------------//
    private void runClient() {
    
    try {
    connectToServer(); // Step 1: Create a Socket to make connection
    getStreams(); // Step 2: Get the input and output streams
    processConnection(); // Step 3: Process connection
    }
    
    // server closed connection
    catch ( EOFException eofException ) {
    System.err.println( "Client terminated connection" );
    }
    
    // process problems communicating with server
    catch ( IOException ioException ) {
    ioException.printStackTrace();
    }
    
    finally {
    closeConnection(); // Step 4: Close connection
    }
    
    } // end method runClient
    
    //----------------------------------------------------------------------//
    
    private void connectToServer() throws IOException{
    client = new Socket( InetAddress.getByName(chatServer), 8000 );
    }
    
    //----------------------------------------------------------------------//
    
    private void getStreams() throws IOException{
    output = new ObjectOutputStream( client.getOutputStream() );
    output.flush();
    
    input = new ObjectInputStream( client.getInputStream() );
    
    output.writeObject( "Client Connected" );
    output.flush();
    }
    
    //----------------------------------------------------------------------//
    
    private void processConnection() throws IOException{
    
    do { // process messages sent from server
    
    // read message and display it
    try {
    message = ( String ) input.readObject();
    }
    
    catch ( ClassNotFoundException classNotFoundException ) { }
    
    } while ( !message.equals( "TERMINATE" ) );
    
    }
    
    //----------------------------------------------------------------------//
    
    private void closeConnection(){
    
    try {
    output.close();
    input.close();
    client.close();
    }
    catch( IOException ioException ) {
    ioException.printStackTrace();
    }
    }
    
    //----------------------------------------------------------------------//
    
    private void sendData( String message )
    {
    // send object to server
    try {
    output.writeObject( "CLIENT>>> " + message );
    output.flush();
    }
    
    // process problems sending object
    catch ( IOException ioException ) { }
    }
    
    //----------------------------------------------------------------------//
    
    } // end class Client
    
    If anyone could even hasard a guess at the issue I would appreceate it,
    also here is output from the java console if its anyhelp.
    
    load: ClientConference.class can't be instantiated.
