  - A splash screenI am trying to create a splash screen. I would like it to be visible for a
    few seconds while the application is initialising. After a timer expires,
    the splash screen will close automatically. I have all of this working just
    fine.
    
    However, at some point during the application initialisation, it creates the
    main window. When this occurs, the main window appears on top of the splash
    screen. I would prefer that the splash screen be "top most" when this
    occurs.
    
    I have tried various combinations of toFront() and toBack() with no success
    whatsoever.
    
    How can I keep my splash screen topmost - preferably without having to mess
    with "lost focus" type of events? In VC++, I could do this by creating the
    splash screen window with the "TOPMOST" attribute set - but I can't find a
    similar attribute in the java window classes.
    
    TIA - Glenn Mc
    
    P.S. For what it is worth, I have attached some snippets of the code I am
    using. SplashPanel extends JPanel and contains all of the components making
    up the splash screen.
    
    public class SqlManEditor extends JFrame {
    
    private static JWindow splash;
    
    private static void showSplash (final int duration) {
    /* final JWindow */ splash = new JWindow ();
    SplashPanel content = new SplashPanel ();
    
    splash.setContentPane(content);
    splash.pack ();
    
    // Center the splash screen in the display.
    Dimension screen = Toolkit.getDefaultToolkit().getScreenSize ();
    int x = (screen.width - content.getWidth()) / 2;
    int y = (screen.height - content.getHeight()) / 2;
    splash.setBounds (x, y, content.getWidth(), content.getHeight());
    
    Thread r = new Thread () {
    public void run () {
    // TODO: Figure out how to get the splash screen
    to be "topmost"
    // Currently when the main window is
    created, it will appear
    // in front of the splash screen.
    splash.setVisible (true);
    // wait for the specified number of milliseconds
    try { Thread.sleep (duration); } catch (Exception e) {}
    // When the timer expires hide the window and get
    rid of it
    splash.setVisible (false);
    splash = null;
    }
    };
    r.start ();
    }
    
    public static void main (String [] args) {
    showSplash (5000);
    SqlManEditor s = new SqlManEditor ();
    s.toBack (); // After these two lines of
    code execute
    splash.toFront (); // s is in front and splash
    is still in back!
    }
    }

  - [(int)Math.floor(x)] or just [x]?here is the situation...
    
    i have an array... and i select something from random from it.
    i pick a random number x by using Math.random() and multiplying it by the
    length of the array.
    but this gives me a double, not an int.
    so when i go to use the array, it needs an int.
    in the language spec, it tells me that round-towards-zero is used when
    going from floating point to integer, and the casting is done
    automatically if possible.
    
    so, given that x is a double, both of these methods are basically
    equivalent:
    
    obj = myArray[(int)Math.floor(x)]
    
    and
    
    obj = myArray[x]
    
    only the top version is "safer" in some sense... it helps explain to
    anyone who would ever look at the code (including the author when having
    to back to it) what is going on.
    
    now, intution says the bottom one is NO SLOWER than the top, because the
    top may incur extra overhead due to the function call stack (for
    Math.floor)... but i'm not sure. when the runtime environment does the
    automatic rounding toward zero, does it basically go through the same
    operations as Math.floor anyhow?
    
    which one would most people here use... and most importantly why?
    
    (note, i may come up with a small test program and try to benchmark the
    two to get a quantitative answer, and i will post when i do.)
    
    thanks again for all the help,

  - Mouse position while drag&drop-operationHi swing experts!
    
    I have the following problem:
    
    I want to move a custom Transferable via Drag&Drop from a JTree to a
    JPanel.
    The transferable should be shown on the JPanel on the position the
    mouse is released.
    
    The trouble is, I can't determine the mouse position on the JPanel.
    The mouseListener and mouseMotionListener-routines on the JPanel
    obviously don't work while in a standard-java-drag&drop operation.
    For example: The JPanel doesn't fire a mouseEntered(..)-Event, when the
    panel is entered during a drag&drop-operation.
    
    So, without Mouse-Events, how do I get the drop-coordinates relative to
    the JPanel?
    
    Any clues?
    Thanks in advance! Your help is very appreciated.
    
    Best,
    Michael

  - Connecting J2ME application to Oracle databaseHello,
    
    For my study I have some questions about Java J2ME:
    
    1. Is it possible to develop a J2ME (CLDC/ MIDP) application, which has a
    direct connection to a Oracle database?
    
    2. Is there a way for using JDBC within a J2ME (CLDC/ MIDP) application?

  - javax.comm - SerialPort ProlemHi,
    
    I tried to install the comm-extensions (with Java 1.5) and copied my files:
    win32com.dll -> \myjdk\jre\bin
    javax.comm.properties -> \myjdk\jre\lib
    comm.jar -> \myjdk\jre\lib\ext
    
    I'm using Eclipse.
    Now to my problem:
    
    A piece of my code:
    
    portList = CommPortIdentifier.getPortIdentifiers();
    try {
    portId = CommPortIdentifier.getPortIdentifier( name );
    } catch(Exception e) {System.out.println("error on comportIdentifier");}
    
    After executing the first line portList is empty and 2 lines later a
    NoSuchPortException is thrown -
    it seems that I did something wrong because I don't get any portIdentifiers
    at all ... but after searching for hours in the internet I only found hints
    where to copy the files but nothing more ...
    
    I would be glad if someone could help me!!
    
    btw: I'm using WinXP

  - Acknowledgment class/deviceWe assume of having a device that generically we model with the Device
    class and that will be best specified with the class VCR extension of
    Device.
    Moreover we assume of having an application (class) Host that knows the
    class Device but not VCR;
    I would to make so that the device recognizes himeself (based on its
    property/features) and that the class Host make an istance of VCR.
    Something like
    Device dev = new VCR(... pars ...);
    
    In practical on different devices I'll have the same classes Device and
    Host and moreover for everyone device I'll have a specific class
    extension of Device (is VCR, PC, Freezer etc.).
    The class extension could be in one specific folder.
    
    How to make?
    Also ideas, suggestions, link

    Clearly we have different opinions on what compilers "should", or
    perhaps "should not" do. I think it's clearly /useful/ for a compiler
    to [be able to] note that there's no use made of some declared entity [1]
    in some codebase and I would not apply a "should not" to remove a
    useful feature. (Usual tradeoff remarks apply.)
    
    I think I'm done.
    
    [1] I spelled `entity` "thingy" in earlier posts, for want of remembering
    the word; I'm not trying to change what I meant.

  - GET and POST in jspHi,
    
    I've been trying to get two parameters passed from a html to a jsp
    page. I can read the correct values of the passed parameters but
    I am having difficulties distinquishing between those values in an
    if-else statement.
    
    The idea is, I need my jsp page to know how the call to it was made. It
    can be an INPUT or a VIEW mode.
    
    I've got an entries.html which is:
    
    <html>
    <body>
    
    <form action="DocView.jsp" method="POST" accept-charset="UTF-8">
    Enter a document of type:
    <SELECT NAME="doctype" SIZE=1>
    <OPTION VALUE="article">article
    <OPTION VALUE="book">book
    <OPTION VALUE="manual">manual
    </SELECT>
    <INPUT TYPE="submit" VALUE="Go">
    </FORM>
    
    <BR>
    
    <form action="DocView.jsp" method="POST" accept-charset="UTF-8">
    Or view an existing document with id
    <SELECT NAME="docid" SIZE=1>
    <OPTION VALUE="1">1
    <OPTION VALUE="2">2
    <OPTION VALUE="3">3
    </SELECT>
    <INPUT TYPE="submit" VALUE="Go">
    </FORM>
    
    </body>
    </html>
    
    and a DocView.jsp one:
    <%
    String doctype = request.getParameter("doctype");
    String docid = request.getParameter("docid");
    
    String mode = "";
    
    if(docid != "") {
    mode = "VIEW";
    }
    else if( doctype != ""){
    mode = "INPUT";
    
    out.println("doctype = " + doctype + ", mode = " + mode +"<BR>");
    out.println("docid = " + docid + ", mode = " + mode);
    
    %>
    
    The if-else statement should identify the type of call was made to
    DocView, based on that, actions will be taken.
    
    The code is just to demonstrate the idea of what I am doing. The
    actuall code reads data from a MySQL database.
    As a result of Docview.jsp I get the correct value of docid if I chose
    an id value or a null if not. The same with doctype,
    either the choosen doctype is displayed or a null. But the variable
    mode does not change.
    It is alway VIEW. Or actually it always gets the value that assigned
    first to it. If I change else-if with the if statement, then the mode
    will always be INPUT.
    Now that leads to the conclusion that mode has to be reinitialized! but
    How?
    
    I can do the same thing with PHP, but there I can use $_GET['param']
    and $_POST['param'] and different if-else statement, and it works
    perfectly. Here is just a snip if the statements in PHP (sorry for
    having to post a php code, but this might clearify my problem more).
    
    $mode="";
    $docid=$_GET['docid'];
    
    $doctype=$_POST['doctype'];
    
    if($docid!="") {
    $mode="VIEW";
    } else {
    $docid=$_POST['docid'];
    if ($doctype!="") {
    $mode="INPUT";
    } elseif ($docid!="") {
    $mode="EDIT";
    }
    }
    
    (the EDIT mode will be added to the jsp later), but this code does
    exactly what I want. how can realize the same in my jsp code?
    
    I appreciate any help on that.
    
    Thankfully,
    Michael

  - Possible to store JSP output as a string?Greetings all,
    
    Ultimately I'd like to use JSP/JSF for templating, very similiar to the
    way I do now with FreeMarker.
    
    I have a chunk of HTML which looks exactly the same on the web and in
    email. I'd like to reuse the same template for both.
    
    I've searched around and haven't been able to find a solution to my
    problem. I could screen-scrape it, but yuck. Am I stuck with
    FreeMarker/Velocity/Etc?
    
    Thanks much!

java-programmer, Monday as first day of the week not sunday hey,

I'm having trouble to tell JAVA that monday is the first day of the week and
not sunday. This is what I have at the moment

Calendar time;
time = Calendar.getInstance();
time.setFirstDayOfWeek(Calendar.MONDAY);

when I output time.get(Calendar.DAY_OF_WEEK) it always gives me a number on
higher then it actually is since it assumes Sunday is day 1. This really is
a annoying bug in my program. Can anyone help me or set me on the right
track ?

thnx in advance

Please don't multi-post.

What do you think the numbers mean?

int j,i = time.get(Calendar.DAY_OF_WEEK);
String s;
switch(i) { // unadjusted; Mon is 2, ..., Sat is 7, Sun is 1
case Calendar.MONDAY: s="Monday";break;
case Calendar.TUESDAY: s="Tuesday";break;
case Calendar.WEDNESDAY: s="Wednesday";break;
case Calendar.THURSDAY: s="Thursday";break;
case Calendar.FRIDAY: s="Friday";break;
case Calendar.SATDAY: s="Satday";break;
case Calendar.SUNDAY: s="Sunday";break;
default: throw new RunTimeException();
}
System.out.println(s);

j = ((i+5)%7)+1; // << adjust so Mon is 1, ..., Sat is 6, Sun is 7
System.out.println(j);
j = (i+6)%7; // << adjust so Mon is 1, ..., Sat is 6, Sun is 0
System.out.println(j);
j = (i+5)%7; // << adjust so Mon is 0, ..., Sat is 5, Sun is 6
System.out.println(j);

  - JDBC extensionHi java developers,
    if you are tired on writing SQL-statements and coding java-classes
    with get- and set-methods for every column, look at
    http://butler.sourceforge.net. It is a object model on top of JDBC
    that makes database programming easier. It also has a generator for
    generating table classes. Feature requests and contributions are also
    welcome.
    
    Best regards,

    When accessing an IMAP folder with Outlook, I can set different colored
    flags. Does this flag the messages on the server side and can I
    retrieve and change that flag via javamail?
    
    (Alternatively, is there any flag (I'm guessing a user flag) that
    javamail can set that can be displayed by Outlook?)
    
    Very many thanks in advance!

  - Tomcat help: Java Beans and servlets not working in user directories with UserConfig, jsp isHello all,
    
    I'm using jakarta-tomcat-5.5.7 with jdk 1.5 on solaris 8.
    
    I have configured in web.xml the UserConfig class as such
    
    <Listener className="org.apache.catalina.startup.UserConfig"
    directoryName="public_html" userClass="or
    g.apache.catalina.startup.PasswdUserDatabase"/>
    
    any jsps in home directories are working but servlets and beans that
    are being
    used
    from jsps are not.
    
    For example I have a directory
    
    /jakarta-tomcat-5.5.7/webapps/steve
    
    in it i have Test.jsp and a subdir WEB-INF in that I have a subdir
    classes and
    in that I
    have a sub directory called blah and in that subdir I have
    Product.class
    Test.jsp uses blah.Product and this all works in the main webapps
    directory.
    
    However if I move the contents of the steve directory to
    ~steve/public_html/webapps
    and I try to load Test.jsp (actually I renamed Test.jsp to
    TestProduct.jsp) I
    get the error
    
    org.apache.jasper.JasperException: /webapps/TestProduct.jsp(3,0) The
    value for
    the
    useBean class attribute blah.Product is invalid.
    
    I however can use a jsp that does not use any beans in the
    ~steve/public_html/webapps
    directory.
    
    I also have a regular servlet that works in
    
    /jakarta-tomcat-5.5.7/webapps/steve
    (with the appropriate web.xml which has the servlet-mapping)
    
    but it won't in
    ~steve/public_html/webapps
    
    Any help is appreciated.

    Build java/jdk-1.4.2p6_4 using GCC 3.4.2 recently committed to -current.
    
    >Fix:
    
    Some notes on the patches. The first one is the only patch needed for the JDK
    itself (it's casting away a const, but needs to be (byte*&) rather than (byte*)
    or else GCC 3.4 won't find the matching member function).
    
    The second patch is a bit of a hack for the Netscape 6/Mozilla plugin (which I've
    verified will load and works okay for both mozilla-1.7.1,2 and firefox-0.9.1_1).
    For UNIX, the correct HAVE_CPP_* macros are supposed to be defined by autoconf in,
    for example, "xpcom/xpcom-config.h" (according to the headers installed by
    Mozilla). But this file is missing altogether from the version of the headers
    installed by the BSD JDK patches, and GCC 3.4 really needs
    HAVE_CPP_MODERN_SPECIALIZE_TEMPLATE_SYNTAX defined or else it fails because
    "template<>" isn't being inserted in the right spots. Since both GCC 3.4 and
    the Metrowerks compiler support all of the HAVE_CPP features, I cheated and reused
    those defines for the NS_UNIX build.

  - ToggleButton oddityI'm trying to create a set of video controls on my application.
    I've added JToggleButtons named jtoggleButtonPlay, jToggleButtonPause
    and jToggleButtonRew. (All part of the same ButtonGroup
    buttonGroupVideoControls)
    There's also a combination of JSlider (jSliderFps) and a
    JFormattedTextBox (jFormattedTextBoxFps) to set the display rate.
    
    The below code is the change listener for the buttons.
    (Each button has a
    jToggleButtonX.addChangeListener(new ToggleButtonListener());
    line for them)
    
    class ToggleButtonListener implements ChangeListener{
    /**
    * stateChanged
    *
    * @param e ChangeEvent
    */
    public void stateChanged(ChangeEvent e) {
    JToggleButton source = (JToggleButton)e.getSource();
    if(!source.isSelected()){
    source.setSelected(true);
    }
    else{}
    if(source==jToggleButtonPlay){
    int fps = 25;
    jSliderFps.setValue(fps);
    }
    else{
    if(source==jToggleButtonPause){
    int fps = 0;
    jSliderFps.setValue(fps);
    }
    else{
    if(source==jToggleButtonRew){
    //at this time lacks any runnable code
    }
    else{
    System.err.println("Event from an invalid source");
    System.exit(-1);
    }
    }
    }
    }
    }
    The jSliderFps:s ChangeListener is set to activate the Play button if
    frame rate is set above 0 and the Pause button if frame rate is set to 0.
    
    However, when I run the application, only the first click on the control
    buttons counts. After that, I can't either activate the other buttons or
    set the active button from the slider's ChangeListener.
    Every attempt to activate a button after that seems to cause a
    java.lang.StackOverflowError.
    
    Any ideas on what's causing this?

  - JEditorPane and HTML offset positionGiven the offset from the start of an HTML document, how I can
    translate this into the offset when the HTML is rendered in a
    JEditorPane? e.g. in the HTML document (not strict HTML but still
    renders):
    
    <HTML>test</HTML>
    
    "test" starts at offset 6 in the HTML - but in the JEditorPane only
    "test" would be displayed so it would start at offset 0 - if I wanted
    to highlight it for example. You can imagine more complicated
    documents...
    
    Any ideas greatly apprieciated including if I can use an alternative
    to the JEditorPane.
    
    Thanks,

  - save with extensionI have following code:
    
    JFileChooser fc = new JFileChooser();
    fc.setFileFilter(/* my class*/ new ExtensionFileFilter("html", "HTML
    File"));
    int returnVal = fc.showSaveDialog(m);
    if(returnVal != JFileChooser.APPROVE_OPTION) return;
    ......
    
    with second line I force dialog to show only html files.
    But I want, when I choose file e.g. "out" then I want final file will be
    "out.html" and if I choose "file.html" the final file will be "file.html"
    
    Is this possible with JFileChooser, or I must write 2 or 3 lines of code?

  - Simple Question: How to see an Error stack trace in Tomcat... (Struts)Hi,
    
    I have a simple probleme, I guees. I have build a simple Java Web App
    (Struts, Log4J) with some JSP pages, and I have some difficulty to see
    the stack trace of a Java Exception when running a JSP page. If the
    page has started to be written, I can see the java exception (I see the
    stack trace in a classic error page). But if the page has been started
    to be written, per exemple when the the java exception is thrown in the
    middle of the JSP page (in a DAO call), I cannot see any stack trace in
    the page in the Log4J log or in the console... Tomcat is catching the
    Exception but not writing it anywhere...
    
    How can I change this? I would like to see the exception either in the
    console or in the jsp page... I could maybe check in the Struts-config
    to redirect Exception in a Error JSP page, but I doubt it would work,
    because the jsp page has started to be written and cannot be change for
    an other one in the process to be written.
    
    Thanks for replying.

  - Java Audio question - PLEASE HELPCould some DSP or Java guru please help me ? I have a simple Java
    application that records audio signals and does simple analysis on the
    collected data. I am using PCM encoding, with sampling frequency 16000
    Hz, 16 bits resolution, single or mono channel, little endian and
    signed.
    
    The data is read into a ByteArrayOutputStream and then as soon as I
    stop recording, the stream contents are written to a byte array, using
    'toByteArray()'. After that, I can get the size of this byte array,
    which gives me the total number of bytes collected, keeping in mind
    that I am using 16 bit resolution, i.e., each sound sample is 16 bits
    long. I am using a software tone generator, with the frequency set at
    500.0 Hertz.
    
    Now, from simple DSP principles, we know that if the number of samples
    collected is 'n' and the sampling frequency is 'fs', then the time
    needed to collect these 'n' samples is n/fs, and the fundamental
    frequency recorded is the inverse of this time value.
    
    However, I am only getting frequencies as low as 7 Hz, or 8Hz, which
    is just absurd. Could someone please tell me if I am doing something
    totally incorrect, or where the flaw in my reasoning is. Any help
    would be greatly appreciated. Thanks in advance for your help.

  - XML and XPathCouple of quick questions regarding Java and XML
    
    Is it possible to parse XML from a string instead of from a file?
    
    Using javascript I could explicitly call a node using
    xmlNode.selectSingleNode("/node1/node[@attribute='whatever']");
    Are there such functions available with Jave?
    
    Cheers

  - controlling printer settingsWhen I print, I want my application to automatically tell the printer
    to expand it's printing to it's maximum so that the margins are as
    small as possible. Is this within java's printing API's ability or
    will the user always have to specify this in their individual printers'
    print dialogs?

  - 73 megabyte NullPointerException objects out of memory'ing our JVMOn our IBM 1.4.1 JVM we sometimes get an out of memory error.
    According the IBM heapdump and heaproots, it is a large
    NullPointerException being thrown from a finalize(). In our
    application, should we catch all exceptions in our finalize() methods
    and prevent them from being thrown further? What does the
    "Finalizer" thread do with the exceptions that it gets from finalize()
    methods? Why does this 73megabyte null pointer happen in the first
    place??
    
    Any suggestions?

  - Why -1 returned from session.getCreationTime() ?When testing my struts code using MockStrutsTestCase the HttpSession
    method getCreationTime() returns -1. A negative value suggests some
    kind of failure but I can't find any reference to this value in the
    API doc. Is it possible to have a session that has a negative creation
    time? If so how can this happen?
    
    When I run my code as a regular webapp under Tomcat 5.0.18 all runs
    ok.
