  - Trying to put a background image in a JFrameTrying to put a background image in a JFrame
    
    I have looked this issue up and found that extending JPanel and
    specifying a paintComponent() is one possibility. I haven't tried this
    yet (and a different task popped up for today).
    
    However, I thought that using the JFrames JRootPane or JLayeredPane
    could be less a hassle. Well, it's not really, but I'm curious if this
    could be solved.
    
    Get the whole NetBeans project with a compiled jar (49kB zip file) here
    [1]. Please don't use the image for yourself, or my boss will kill me.
    
    What happens is that the image (with transparent areas) is painted
    infront of components instead of behind. Actually, when I first start
    the application, the image is infront of one button and behind the
    other. Moving the mouse over a button brings it to front, resizing the
    window will put all components behind the image.
    
    By the way, in the final project, the window will not be resizable,
    although I would appreciate some hint towards catering for the image
    being anchored to the lower right corner aswell.

  - HTTP Persistent connections on Apache web-serverHi,
    
    I need to implement a solution which needs a HTTP persistent connection
    
    from the client( any browser ) to the webserver ( Apache here )
    
    This is how I am trying to acheive the persistent connection:
    
    For every user logging on to the webserver, the browser sends a HTTP
    request to the webserver which is being handled by a servlet on the
    webserver. The servlet then creates a thread which holds the response
    object and waits for some asynchronous data coming from a diff backend
    sever.
    As soon as some data is posted on to this thread, this thread sends
    back the data to the clent on the response object that it has been
    holding as a java-script object.
    This thread is terminated only when the user logs out od the webserver.
    
    Now, I have a few questions on this part:
    
    1) I find that it is not an appropriate solution, given the fact that
    the webserver needs to cater to 20-30k users at a time and creating a
    thread per user on the webserver would really not solve the purpose. Am
    
    I right ? ( The webserver would die is n't it?..)
    
    2) Also, is there any limitation on the time that the thread can hold
    the response object? like if the thread doesn't get any data posted on
    to it from a diff backend sever, will the client( here IE or mozilla )
    close the underlying socket connection ?
    
    3)Any limitation on the scalability of this approach ( I want to know
    to how many users will this approach solve )?
    
    4) Now given my inner feeling that this approach won't work well, what
    is the best way to implement a lonf-lived HTTP persistenet connection
    from my browser to the webserver.
    (Please note that the webserver need to push some asynchronous data to
    the client as long as the user is logged on the webserver ..no refresh
    mechanism please )
    
    Apprecaite if reponded well!!!
    
    Thanks in advance to ALL

  - Help! Constructors not workingI'm doing an assignment for a Java class. Basically, we have to build
    constructors for a class, Television, whose attributes are *brand* and
    *price*. I have defined the constructors and accessor and mutator
    methods in Television.java, and access it via TelevisionClient.java
    (code for both is posted below). Both files compile. However when I
    run TelevisionClient, it runs through the code, but my constructors,
    tv0, which I assign a value in the program, and tv1, which is assigned
    through dialog boxes at runtime, are the same value - in other words,
    even assigning a value to one, they both have the values that are
    passed in through the dialog box. I appreciate any help.

  - Outsourcing to India and Chinayeah there was a philosopher back in the 60s by the name of
    thornkinson (god i hope that's right) but he went into detail on how
    society will eventually solve all its problems through efficient
    technology. he supposed built a vehicle that can do like 50mpg back
    then.
    
    the light bulb is an interesting question tho. its horribly
    inefficient. hasn't changed since edison created it. its used by
    literally everyone. you would think someone would realize the
    potential in mass producing something better..
    
    however i don't think its physically possible to heat a home using 3
    lightbulbs. besides a lightbulb mostly creates heat.

  - measuring signal strength in javahello
    
    i am writing a java program for locating a wireless device within an
    office environment. i want to use the signal strengths of the
    surrounding base stations (access points) to estimate the current
    location of the device.
    does anybody have an idea how to get the strength of a signal sent by
    a base station in java?

  - tablet stylus as graphicI am wondering if there is a simple applet somewhere, which I could embed in
    an html form, such that on a tablet pc, using the tablet's
    stylus, sign in some field, that field then, rather than being converted to
    text(as is typical in tablets) is then maintained as an image, then, the
    form is posted to a mysql database where the image of the signature is
    retained as such.
    
    Does anyone know of such an animal, or even something remotely like this?
    Thanks, Ike

  - Using Java with Dual & Quad Processors.I have a function which I call using for loop. I want that when My
    Java program is run on Dual Core its speed increases by twice and when
    it run on Quad core its speed increase 4 time.
    
    Here is the Code I am using.
    
    const NUMBER=1000;
    Public int int_x;
    Public int[] Array1= new int[NUMBER];
    
    init (){
    for (int i=0;i<NUMBER;i++){
    
    function_abc(i);
    }
    }
    
    // function_abc returns same value for a given Value of "i".
    
    function_abc(int i){
    int_x++;
    ...
    ...
    ...
    Array1[i]=i*5+int_x;
    }
    
    So in the end we get an Array[i] with the formula values. On a single
    processor it goes through all the for loop in NUMBER times.
    
    I want on Dual Core the Performance doubles by using Threads. So
    function_abc(i); is Called in multiple threads and Speed increases X
    times depending on number of X Processors the System has.
    
    How can it be done, any idea.
    
    So for Single Core it will have no spped increase.
    
    For Dual Core Twice Speed
    
    For Quad Core 4 Times speed is seen.
    
    Bye

  - escape meta for Pattern?On
    http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
    
    it says:
    > The string literal "$hello$" is illegal and leads to a compile-time error; in order to match the string (hello) the string literal "\$hello\$" must be used.
    
    Now, if I read my input strings from a file I have to convert my
    strings in order to match them against a pattern. How do I do that?
    Is there a predefined method to do it? Like quotemeta in perl?
    
    Thanks!

  - javadoc to ms word docAnyone got some tips to ease the conversion from javadoc to ms Word?
    
    I've got the source code, I can produce html and yes ms word does understand
    html, but its a laborious process with 50 files. And the html tables never
    fit the width correctly.
    
    Any tools to javadoc straight from source to ms .doc ?

    Please post some of your code. It's easier to talk about this using real
    names of Action classes and Forms.
    
    I'm guessing Action1 fortwards to JSP1 which has the username field (a
    login form?) When you submit that, it goes back to Action1, which sees
    that the value is present and forwards where?

  - Log4J problemHi everyone,
    
    Consider the following piece of code:
    
    Logger mylogger = Logger.getLogger(Log4JFileDeletionTest.class);
    
    public Log4JFileDeletionTest() throws Exception
    {
    FileAppender fapp = new FileAppender(new
    XMLLayout(),"/tmp/Log4JFileDeletionTest.log",true);
    mylogger.setLevel(Level.DEBUG);
    mylogger.addAppender(fapp);
    
    mylogger.info("This is a test log");
    
    Thread.sleep(7000);
    
    mylogger.info("This is after deleting the file");
    }
    
    If during the Sleep(), I delete the log file, then none of the
    subsequent log statements re-create the file. It remains deleted, no
    exceptions get thrown and all the logs are lost.
    
    Is there any solution to this, other than modifying the log4J code ?
    
    Thanks in advance.

  - reflect fieldHi all,
    
    I want to get value of string variable in a class, and field it with
    new strings like this :
    
    EXample
    
    public class helloWold()
    {
    String myString1 = "test1";
    String myString2 = "test2";
    String myString3 = "test3";
    String myString4 = "test4";
    }
    
    public static void main(String[] args) {
    Field myField[] = helloWold().class.getFields();
    
    for (int i = 0; i < myField.length; i++)
    {
    System.out.println(myField[i].getName()); //get value
    }
    }
    
    Actually I get the value, but i didn't know how to field it. I try the
    method set but i have an error
    'an not set java.lang.String field to java.lang.String'
    
    Any ideas
    
    Thanks.

  - Reading from URLConnection stops at JavaScript alert callHi all,
    
    when I post form content to a server (HTTPS protocol) using a
    URLConnection and then reading the servers response using a
    BufferedReader, the reader seems to stop just before reading the code
    for a JavaScript alert. The code for reading the response looks like
    this:
    
    in = new BufferedReader(
    new InputStreamReader(connection.getInputStream()));
    stbResult = new StringBuffer(5000);
    while ((sResult = in.readLine()) != null) {
    stbResult.append(sResult);
    }
    
    When accessing the same site with a browser a dialog pops up at the
    crucial point. After clicking away the alert the rest of the HTML page
    gets loaded by the browser.
    When looking at the code of the HTML page later on, I can see that the
    response read by my java app ended just before the JavaScript code:
    
    <SCRIPT LANGUAGE="JavaScript">alert("xyz");</SCRIPT>
    
    I need to read in the whole page including the alert message. How can
    I get my java app to read in the JavaScript code within the HTML page
    (no problem occured with the JavaScript code in the header) and the
    remaining HTML code?
    
    Thanks for thinking about this one!

  - new version of Open Content Software Design web bookI have an updated version of my Software Design web
    book (free!) that is primarily Java centric. This
    web book is not as complete as my "Java AI" and "Introduction
    to Common LISP" web books, but it is hopefully in a usable
    state as-is. I am especially looking for feedback
    on how to improve it (the Common LISP community was
    awesome in providing great feedback for the free LISP
    book - can the Java community do the same :-)

  - Announce: A new open source O/R mapping toolAnnounce:
    
    Molly DBO: A new open-source O/R mapping tool is out.
    
    There are many such programs out there. But this one is very
    special because it's simple (no xml configuration, yay !) and has
    been tested with postgres and mysql. This tool has been used
    extensively in production enviroments so the generated code has
    most bugs squeezed out by now.

  - Porting C++ Template to Java GenericI've run into a road block with porting some C++ code that makes use
    of templates to Java. In it, there is a main class I'll call A that
    is a template class:
    
    // C++
    template <class T> class A
    public:
    virtual T Evaluate() const = 0;
    };
    
    Other classes extend this class:
    
    // C++
    template <class T> class B : public A<T> {
    public:
    B(const T &v) { value = v; }
    T Evaluate() const { return value; }
    private:
    T value;
    };
    
    Now all of this is easy to implement in Java using Generic
    programing. The issue I'm having is when I try to implement code like
    this:
    
    template <class T1, class T2> class C : public A<T2> {
    public:
    C(A<T1> a, A<T2> b) { t1 = a; t2 = b; }
    T2 Evaluate() {
    return t1->Evaluate() * t2->Evaluate();
    }
    private:
    A<T1> t1;
    A<T2> t2;
    };
    
    Java complains about about the * operator being undefined for
    arguments T1, T2; Since Java doesn't have operator overloading, I
    can't really see how to implement the same functionality. Has anyone
    ever encountered this type of problem, or can anyone see a way around
    this issue?

  - edit jtable with enteri am having a problem with jtable which i was unable to solve for a
    last couple a days. i think there needs to be much more docs on some
    tricky uses of jtable than basic JTable/TableModel usage. so far i
    managed to move to the next cell when i press enter (right hand side,
    instead of moving down).
    
    i'd like to start editing in the next cell after moving from previous
    cell. so, if i was in editing mode in some cell, enter should bring me
    to the next cell with caret blinking in it. of course, if i wasn't
    editing some cell i don't want to edit next cell.
    
    basicly, i want to make "row edit session", for example user starts
    editing a cell with f2, and as long as he press enter he edits next
    cell, until he reaches the end of the row and then changes are
    commited to database, just like M$Access and SQLserver does. i think i
    can do this myself, all i need is little help to start edit next cell
    if user moves from previous cell. i checked BasicTableUI source, and
    as i see i should get the editor component and request focus on it.
    but i am stuck with that.
    
    thanks!

  - A question about Java ThreadI see a code like this:
    
    in a Thread:

    while (thread == currentThread) {
