    Agreed. The only thing different about "primary" keys from any other
    key is uniqueness -- a selection by primary key will return only one
    record. Other than that constraint, many databases treat them exactly
    the same as non-primary keys [e.g., can form indexes on them, etc.].

    +---------------
    
    Not in "ANSI SQL92", say, but there might be in most SQL databases!
    [See below re OIDs. Also, SQL:1999 had a "REF" type that was essentially
    and OID.]

    Don't confuse "SQL" & "relational algebra"!! You'll get real
    relational algebraists *way* bent out of shape if you do that!

    | Primary keys are updatable; there is nothing special about them.
    +---------------
    
    I think he's probably talking about "OIDs" (object IDs). Most
    current SQL-based databases provide them, usually as a normally-
    invisible "system column" that doesn't show up when you say
    "SELECT * FROM", but that *does* appear if you say "SELECT oid, *",
    and may be used as a "primary" key even on tables with no actual
    primary key:
    
    rpw3=# select * from toy limit 4;

  - Packaging/version controlI'm developing a Swing program which I periodically update (change or
    add classes or data files), weekly, to currently 2 people. The number of
    people will eventually grow but the update frequency should decrease.
    Currently, I'm putting the sources, classes, data files and a readme
    file into a zip and sending it. The readme tells the users to either
    compile or copy the classes over. There are ~25 .java files, ~75 .class
    files and ~20 data files. This is time consuming, inconsistent and error
    prone. I'm not using package statement or jars (currently). What are
    people using and / or what would you recommend. - Thanks - Lou

    That is not the issue. The issue is whether there are mechanisms to
    detect the error or you simply get undefined results.
    
    Think for example writing C code where you failed to initialise a
    variable. This was legal. Most of the time it was initialised to 0.
    But sometimes it was not, leading to a need for a timeout in a padded
    cell. It STRONGLY matters if the compiler/run time can detect the
    error.
    
    It is almost irrelevant if the given code is technically legal.

  - What's the proper way to use SocketChannel.finishConnect()?What's the proper way to use SocketChannel.finishConnect()?
    
    I've read the documentation but couldn't comprehend what is written for it.
    
    I've seen examples where it is placed:
    
    1a) Right after SocketChannel.connect() (without while loop)
    
    SocketChannel sc = SocketChannel.open();
    sc.connect(...);
    sc.finishConnect();
    sc.configureBlocking(false);
    sc.register(selector, SelectionKey.OP_READ);
    
    1b) Right after SocketChannel.connect() (with while loop)
    
    SocketChannel sc = SocketChannel.open();
    sc.connect(...);
    while (!sc.finishConnect()) {
    }
    sc.configureBlocking(false);
    sc.register(selector, SelectionKey.OP_READ);
    
    2a) When iterating the Selector.select() values (without while loop;
    
    SocketChannel sc = SocketChannel.open();
    sc.connect(...);
    sc.configureBlocking(false);

  - JSP <jsp:useBean ... /> tag: Difference between 'class' and 'type'Hello,
    
    I'm trying to gain a better understanding of the included tag libraries
    with JSP. The <jsp:useBean tag seems farily straightforward, in that it
    sets a page variable from an object in any scope, with a variety of options.
    
    I see examples listed that interchange the 'class' and 'type' attribute,
    but to me it's not real clear as to their distinction. Can anyone
    explain their difference?
    
    One thing I have noticed is that if I don't yet have a variable declared
    in the given scope, using the 'type' attribute causes an exception to be
    thrown, whereas the 'class' attribute does not. It seems that when I
    specify "class", it actually creates a new instance of the specified
    variable / bean.
    
    Thanks!!

  - native method performance puzzleJust to be clear, I'm afraid that I can't do more than sketch my problem out
    here, since it's customer-specific, but I'm hoping for some direction.
    
    I'm testing two implementations of a data-processing API, one in pure Java,
    one in native methods (windows dll). The process I am testing is disk I/O
    intensive.
    
    Running the same performance test over and over again I've found that the
    pure Java implementation gives very consistent results, while the native
    method version gives results that steadily get better over about a dozen
    runs, finally ending up about the same at the pure Java implementation
    (probably ultimately limited by disk thruput).
    
    For example, test 1 might look like:
    
    pure Java method : 12 sec
    native method: 20 sec
    
    test 5 like:
    
    pure Java method: 11 sec
    native method: 15 sec
    
    test 10 like:
    
    pure Java method: 12 sec
    native method: 10 sec
    
    What could be going on here? It sure feels like something is being cached,
    but I'm not sure what.
    
    Thanks,

  - Java 5.0 Flood!Since J2SE 5.0 has just come out, I'd thought I'd post a some links and
    highlights as written by the media around the internet.
    
    ---
    
    ** Sun ships Java upgrade, focuses on ease of use **
    The next release is due out by early 2006
    
    Highlights:
    - "J2SE 5.0 is an important step for Java in its ongoing battle against
    Microsoft Corp.'s .Net development environment", said Stephen O'Grady, an
    analyst at RedMonk Inc. in Bath, Maine. "The streamlined start-up times and
    a friendlier graphical user interface should be especially welcome additions
    to Java users", he said.
    
    "Particularly for Java applications on the client, it has taken a while for
    them to start up," O'Grady said. "That has been a problem. Also, from a
    user's perspective, [Sun] has updated the look and feel. It looks good. It's
    cleaner, and it's more modern."

    ** Sun Releases New Version of Java for Servers, Desktops **
    
    Highlights:
    - In addition, Austin said J2SE 5.0 will spark the creation of new tools for
    developers, particularly new profiling and analysis tools. "We have a cool
    technology called byte code insertion, so now you can profile in real-time."
    J2SE 5.0 also enables developers to "pre-template" code, "so other analyzing
    tools can read the metadata," he said.

    ** A New Direction for Java **
    
    Highlights:
    - The result: "Java's beginning to wend its way into some pretty interesting
    places," such as automobiles, said Schwartz. "I asked an automobile
    manufacturer, 'What's the price at which, if you could sell online services
    to the automobile, you could give away the automobile for free?' Without
    batting an eye, that auto company's CFO said, '$220,'" Schwartz told his
    JavaOne audience. "Now think about that. "Do you know a 17-year old who
    would pay $5 to download a custom horn tone to his car? I do," he said.
    
    - "It's not Sun thinking about putting services into an automobile, it's
    Siemens and BMW," Schwartz said, returning to center stage after a
    presentation in which a new BMW rolled out with an advanced Java-based
    navigation and entertainment system.

    Comments on Synth
    Synth is apparently a 'bare-bones' L&F designed specifically to allow
    non-programmers to turn it into a custom L&F using simple XML. The article
    "The Synth Look and Feel" in the next section gets more into the details.
    An example XML file is also presented below. For an overview of the idea
    behind Swing 5.0 see this article:
    
    ** Tiger on the Desktop **
    http://weblogs.java.net/blog/chet/archive/2004/09/tiger_on_the_de_1.
    
    ** The Synth Look and Feel **
    
    Highlights:
    
    For the anxious, here's a quick example. The following XML code, taken from
    example1.xml, defines a style named textfield and binds it to all text
    fields in Synth. The result is that text fields look like the one in the
    Motivation section.
    
    <synth>
    <style id="textfield">
    <state>
    <color value="white" type="BACKGROUND"/>
    </state>
    <imagePainter method="textFieldBorder" path="textfieldborder.png"
    sourceInsets="5 6 6 7" paintCenter="false"/>
    <insets top="5" left="6" bottom="6" right="7"/>
    </style>
    <bind style="textfield" type="region" key="TextField"/>
    </synth>
    
    Here's some code that loads the XML file into Synth and sets the current
    look and feel to Synth:
    
    SynthLookAndFeel laf = new SynthLookAndFeel();
    laf.load(Example1.class.getResourceAsStream("example1.xml"),
    Example1.class);
    UIManager.setLookAndFeel(laf);

  - a common yet hard-to-resolved problem for Java GUI size!The Java application GUI (setPreferSize to some hardcoded dimension)
    gets smaller when it comes to wide screen (Dell 16:9 laptop), and the
    users have to resize the GUI every time they are launched (so as to see
    the action buttons). This problem seems to happen only for 16:9 wide
    screen so far.
    
    Question:
    1. What are the factors deciding the swing (awt) GUI size, besides
    resolution and font? Is wide screen really an individual factor?
    
    2. How to formulate a universal good GUI size? Or any examples to
    define different sizes for different display-cases?
    
    Thought the following functions might be needed, although I heard that
    Toolkit.getScreenResolution() cannot really detect screen resolution.
    
    Toolkit.getScreenResolution(), Toolkit.getScreenSize(), getFontSize()
    
    Any example or information will be highly appreciated!

  - Component inside JList not painting; now resolvedI have set up a JList to work with its own ListModel and
    ListCellRenderer. The symptom, my component does not
    display any text. That is the list box is
    completely blank. From the debugging, I saw it displayed the desired
    text. And, we saw that the list box scrolled when there was more data
    than can be displayed.
    
    The problem turned out to be that I defined paint() rather than
    paintComponent(). What was strange was that I was able to use other
    classes extending Component that I wrote and return them
    from the ListCellRenderer. These had the same mistake
    of putting the display logic in paint() rather than paintComponent();
    Yet those Components worked fine and this error in the class notes from
    which
    I taught our GUI course since 2001.
    
    One of my students , Mr. Kevin Kraus,
    elucidated the solution to this problem -- Thanks!
    
    This was also discussed in this group in
    relation to a post from John Creighton on September 2 2001.
    
    Since, this is an easy error to make, it is worthwhile having the
    reminder, here.
    I did not see anything saying this in the FAQ but section 3.4
    told our users not to use Component.getGraphics(). They were told
    to override "paint()(AWT)" or "paintComponent()(Swing)"
    I am sending a suggestion to Mr. Weidenfeller
    of new wording to help people trouble shooting their
    programs.
    
    Here is my component definition:
    
    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.*;
    
    class NumberComponent extends JComponent {
    String FontName;
    String ToDisplay;
    int Size;
    boolean Selected;
    Font f;
    void setSelected (boolean S){
    Selected=S;
    }
    NumberComponent (String S) {
    ToDisplay = S;
    Size = 12;
    FontName="Arial";
    }
    NumberComponent (String S, String F, int size) {
    Size=size; FontName = F; ToDisplay = S;
    }
    public void paint (Graphics g) {
    System.out.println ("font Name " + FontName + " Size " + Size);
    if (!Selected) {
    f = new Font (FontName,Font.PLAIN,Size);
    }
    else {
    f = new Font (FontName,Font.BOLD,Size);
    }
    //g.setFont(f);
    g.setColor(Color.black);
    //g.fillRect(10,10,30,20);
    
    g.drawString (ToDisplay,0,0);
    System.out.println (" here " + ToDisplay + " hc " + hashCode());
    }
    
    public Dimension getMinimumSize() {
    if (!Selected) {
    f = new Font (FontName,Font.PLAIN,Size);
    }
    else {
    f = new Font (FontName,Font.BOLD,Size);
    }
    int Width = getFontMetrics(f).stringWidth(ToDisplay);
    int Height = getFontMetrics(f).getHeight();
    System.out.println (" Width " + Width + "Height " + Height);
    Dimension D = new Dimension (Width,Height);
    return D;
    }
    public Dimension getPreferredSize() {
    return getMinimumSize();
    }
    public Dimension getMaximumSize() {
    return getMinimumSize();
    }
    }
    
    Here is the output from the list box that is using it to display:

    rt.exec(s);
    
    This is commented by the interpreter as follows:

  - [ANN] Luxor XUL Standard Widget Toolkit (SWT) Layout Pack Now LiveHi,
    
    I've uploaded the Luxor *Standard* Widget Toolkit (SWT) Layout
    package that shows you how to turn SWT layout managers such as
    FillLayout, GridLayout and others into easy-to-use XUL tags that you
    can use in addition to the built-in XUL box layout system.
    
    This preview includes XUL tags for
    
    * FillLayout
    * RowLayout
    * GridLayout
    * SashForm
    
    Here are some examples to see what's it all about:
    
    FillLayout In Action
    --------------------
    
    The FillLayout is mapped to the <fillbox> tag and you can use it like
    any other XUL box. Example:
    
    <fillbox>
    <label value="Instructions:" />
    <label value="1. Fill in your name" />
    <label value="2. Fill in your age" />
    <label value="3. Fill in your gender" />
    <label value="4. Check the box for employment" />
    <label value="5. Click on OK" />
    </fillbox>
    
    GridLayout In Action
    --------------------
    
    The GridLayout is mapped to the <gridbag> tag and the GridData is
    mapped to the <griddata> tag. Example:
    
    <gridbag columns="3">
    <button label="B1" />
    <button label="Wide Button 2" />
    <griddata rowspan="2" fill="MAX">
    <button label="Button 3" />
    </griddata>
    <button label="B4" />
    <button label="Button 5" />
    </gridbag>
    
    SashForm In Action
    ------------------
    
    The SashForm is mapped to the <splitbox> tag. Example:
    
    <splitbox id="splitbox3">
    <button label="One" />
    <button label="Two" />
    <splitbox orient="vert">
    <button label="One" />
    <button label="Two" />
    <button label="Three" />
    </splitbox>
    </splitbox>
    
    and so on and so forth

java-programmer, Beware of disabled Action Hi !

just a note to warn you about some javax.swing.AbstractAction problem

My GUI dispays a JButton.
depending on the user's state, I do a setAction(AAction)
or a setAction(BAction).

AAction and BAction each extend AbstractAction and possess their own icon
(ImageIcon).

Here is a sample scenario :

1) button.setAction(AAction)
2) AAction.setEnabled(false)
3) button.setAction(BAction)
4) BAction.setEnabled(false)

the result of this is : the Action linked to the button is BAction as
expected, and the icon is...AAction's disabled icon (original icon greyed).

The only workaround I've found is to do button.setDisabledIcon(null) before
any new setAction()

It seems that an AbstractAction doesn't possess a disabled icon on its own,
and relies on the JComponent's one.
The first time, 1) and 2) have the consequence of creating a disabled icon
for my button , which doesn't have any at the beginning.
Then, 3) and 4) won't change this disabled icon, because the button now has
one

Regards,

Arnaud

  - What means %10.7f?Hi,
    
    My code has:
    
    System.out.printf("%10.7f", aDouble);
    
    My intention is to print out the value of a double variable following
    the rule: a)the maximum space is 10; b)have 7 digits after the decimal
    point.
    
    But there is a bug here, I found. If aDouble < 100, it is fine; If
    aDouble >= 100, it will take 11 spaces, instead of 10 spaces. So I have
    to manually change 10.7f to 10.6f. What a pain!
    
    Could you help me out? Thank you.

  - jtextarea and htmlHi,
    Is it possible for me to setup up jtextarea such that
    it renders html.
    Suppose I create a but "interpret html" which when clicked
    goes through the text in jtextarea and
    adds styles
    for example if I have something like
    <b>bold text here</b>
    
    then this should be bold. Furthermore, it should hide these html
    tags but not delete them, that way when i save the text, i save the html
    tags as well.
    
    thanks for any advice

  - ZoneView: does it work?I'm going to repeat a question that i've asked in javalobby to no
    avail.
    
    Did anyone ever got zoneview working for a JEditorPane and if so how?
    
    I'm using a custom stylededitorkit that implements view factory and my
    factory code looks like this:
    
    public View create(Element elem) {
    String name = elem.getName();
    
    if (name != null) {
    if (name.equals(AbstractDocument.ContentElementName)) {
    return new LabelView(elem);
    } else if (name.equals(AbstractDocument.ParagraphElementName)) {
    return new CountingParagraphView(elem,observer);
    } else if (name.equals(AbstractDocument.SectionElementName)) {
    return new ZoneView(elem, View.Y_AXIS);
    } else if (name.equals(StyleConstants.ComponentElementName)) {
    return new ComponentView(elem);
    }else if (name.equals(StyleConstants.IconElementName)) {
    return new IconView(elem);
    }
    }
    return new LabelView(elem);
    }
    
    Ignore the contngparagraph view, its just something i did to be able to
    tell the amount of text visible.
    
    Using zoneview here gives an nullpointerexception in the guts of swing,
    in AsyncBoxView i think.
    I'm just looking for a way not to load to the views the entire text at
    a time (That is sloooow). And getting an indicator of the index of
    text. I'm going to append my editor kit and textpaintobserver if you
    want to see how it works (to make it work, just replace zoneview with
    boxview in the method above).

  - Executing a jar fileI have the following code

    }
    }
    
    If I execute the class file from a cmd windown I get the start up
    screen from the cprog.exe, however as I would like to dispense with
    the dos window I packaged the class into a jar file
    
    First creating a text file called WinTest.txt containin the single
    line
    
    Main-Class: WinTest
    
    Then create the jar file
    
    jar cmf WinTest app.jar WinTest.class
    
    I associated the jar file with the java.exe in the SDK lib
    
    But when I double click to execute the jar file a dos window pops up
    disappears but no start screen from the cprog.exe is shown
    
    I'm sure it is a severe user error must I have to admit to being
    stumped and help would be nuch appreciated

    problem.
    
    Today, without having made any change to the code, I had the bad surprise to
    see the following exception in my logs :
    
    java.lang.ClassCastException
    at sun.nio.ch.OptionAdaptor.<init>(OptionAdaptor.java:27)
    at sun.nio.ch.SocketAdaptor.opts(SocketAdaptor.java:253)
    at sun.nio.ch.SocketAdaptor.setTcpNoDelay(SocketAdaptor.java:258)
    at aks.net.AKSAcceptDaemon.run(AKSAcceptDaemon.java:135)
    
    My code looks like : (file AKSAcceptDaemon.java)
    
    Selector m_acceptSelector ;
    
    ... // selector initialisation
    
    while (m_bRunning)
    {
    Set readyKeys ;
    Iterator it ;
    SelectionKey sk ;
    ServerSocketChannel ssc ;
    SocketChannel client;
    
    while ( m_acceptSelector.select() > 0)
    {
    readyKeys = m_acceptSelector.selectedKeys();
    it = readyKeys.iterator();
    
    // Walk through the ready keys collection and process
    date requests.
    while (it.hasNext())
    {
    sk = (SelectionKey)it.next();
    it.remove();
    
    if (sk.isAcceptable())
    {
    ssc = (ServerSocketChannel)sk.channel();
    client = ssc.accept();
    client.configureBlocking(false) ;
    // HERE IS THE GUILTY LINE
    client.socket().setTcpNoDelay(false);
    // HERE ENDS THE GUILTY LINE
    client.socket().setKeepAlive(false);
    m_engine.addNewClient(client) ;
    }
    }
    }
    }
    }
    
    Does someone see what can be the reason of this ?
    I made a search on newsgroups, but didnt' found any answer.
    
    Thanks in advance,
    
    Cam
    
    PS : sorry for my crap english : I'm french and frenchies have never been so
    good at foreign languages :p

  - JavaMail GNUMail, Knife, Classpath and gnu.inetOk, here is the deal. I am trying to install a ready to go NNTP
    provider for jmail. This lead me to the Knife project, which lead me to
    GNU mail which lead me to Project classpath which has led me to a huge
    patchwork of downloads.
    
    Has anyone else tried to get this all working? I know for sure that the
    code modules I downloaded are not compatible with eachother. One set of
    code, for example, is calling on constructors and methods with wrong
    method signatures.
    
    Does anyone have something to say on this? Am I missing something? Open
    Source is fairly good at avoiding this sort of thing, but then again...

  - database content as objectsI wonder what is so appealing in mapping of database content to
    predefined Java (or some other language) objects.
    
    There is a problem with joins in he first place. There is lot of coding
    and processing overhead.
    
    I found it more elgant to store data in HashMaps. If I need an object,
    I could always provide a class with a constructor that takes HashMap as
    parameter.
    
    Reporting can be much easier that way, too. I used it in a couple of
    projects, and find it very handy.

  - developing web browser and email clientHi people...
    
    I am planning to develop a webbrowser and e-mail client..but i haven't
    done this work before.
    
    Can you please tell me which language is the best to go ahead with it
    ? And what are the prerequisites that i need to learn ?
    
    I'll be thankful
    
    Regards
    Anupam
    
    I am planning to create a s/w package that'll install both of these..

    Type:
    
    set
    
    and press <ENTER>; you should find a number of items displayed:
    
    PATH=...
    CLASSPATH=...

    I find this a highly unusual situation. Ordinarily, you would have at least
    a couple of environment variables displayed.
    
    >
    > How do I change the settings like CLASSPATH
    >
    
    To create a CLASSPATH enviorment variable where none exists, do:
    
    set CLASSPATH=C:\XYZ;D:\ABC
    
    and press <ENTER>.
    
    To add information to an existing CLASSPATH [you can choose whether to place
    it before or after existing data] do:
    
    :: Before existing data
    set CLASSPATH=%classpath%;C:\XYZ;D:\ABC
    
    or:
    
    :: After existing data
    set CLASSPATH=C:\XYZ;D:\ABC;%classpath%
    
    and press <ENTER>.
    
    Note, though, this changes the settings for the current console window [i.e.
    DOS Window] only - the settings are lost once you close it. For a more
    permanent solution:
    
    * Edit 'autoexec.bat' file to include the above statements - this
    applies to older Windows versions
    
    * Use the System applet in the Control Panel to edit Enviromnent
    Variables [for W2K, and XP]
    
    I hope this helps.

  - Java localization on MacDear developers,
    
    I made a Java application. I packed it as an ".app" container using Jar
    Bundler, then I launched the ".app" and I saw that the standard menu
    (the one with About and Quit commands) is in English and not in my
    system's default language. How can I get it localized?
    
    Thank you :)

  - help with my first project on first job, how to read a strange file, thanks a lot!!!!!!!the OS is mainly windows. i doubt windows has powerful tool to do the
    job automatically.
    i need to open and close the file frequently because another process
    is writing to the file. then Java create a new object each time I open
    the file. in this case, can the program remeber the position I set
    last time?
    if yes, can i do the same thing with BufferedReader class instead of
    RandomAccessFile. i am not sure whether RandomAccessFile can easily
    allow me to keep the new line characters and white space among the
    valid text. i need these chars in the application. The length() can
    not help me a lot, since the file size does not change when new text
    is written into the file. the new text write over the whitespace but
    do not change the file size.
    thanks again!
