  - Design question about data conversion class.I'm looking for a name for my class that reflects what it does. Its a
    class with functions that converts data.
    
    For example, my current class is called ArticleValueObjectCreator. It
    has a method that converts resultsets to an article value object bean.
    
    I now need to create a method which converts an article related
    resultset to xml. In the future I may need one that converts a value
    object "bean" to xml.
    
    I'm thinking of refactoring the class now that I need to grow it.
    
    What is the best way of acomplishing good design here?
    
    Would renaming the class to something like ArticleDataCovertor, or
    ArticleAdaptor tie in with good programming practice, or would it be
    better to split these methods up into different classes ( thus making
    each class dependent on a fine range particular technologies ) eg, one
    which is xml and jdbc only, another that is xml only.
    
    Are there any design patterns like this that emphasise clean
    seperation between technologies. Or am I over-engineering?
    
    Thanks

  - calling java from DOTNET 2? how stable or painfull?hi.. (sorry but i posted this in a dotnet newsgroup as well becoue i
    don't know which would be better handling this question).
    
    i have a java application server whish uses RMI as a delivery transport
    for it's apis (it's gets the command in XML but the underlying protocol
    needs to be RMI)..
    
    so i need to write an RMI CLIENT to this thing, and expose it microsoft
    land.
    
    at first we thought to have it exposed as web service and consume this
    service via dotnet dll. the dll would be given to desktop application
    developers which canno parse XML.
    
    then i was told i could expose it as JNI and have the dll access it
    directly. then the dll in dot net 2.0 would either be given to desktop
    developers or exposed as a web service in biztalk if web services are
    needed.
    
    btw can i do all of this with express edition versions?

  - URL Class Loader & file deletionHello,
    
    The following code always displays "File cannot be deleted".
    Any idea on the way to allow a file to be deleted when it has been used
    by a URL class loader to load code ?
    
    public class ClassLoaderTester {
    public static void main( String[] args ) {
    try {
    String s = "c:\\zob.jar";
    URLClassLoader oCL = new URLClassLoader(
    new URL[] {
    new File(s).toURL()
    } );
    Class c = oCL.loadClass("com.mysql.jdbc.Driver");
    Object o = c.newInstance();
    o = null;
    c = null;
    oCL = null;
    
    System.gc();
    System.runFinalization();
    
    File oFile = new File(s);
    if ( !oFile.delete() ) {
    System.err.println("File cannot be deleted");
    }
    
    }
    catch ( Exception e ) {
    e.printStackTrace();
    }
    
    }
    }
    
    Thank's in advance.

  - Batch image compression problem. Help!I am using Java to develop a web application that lets user to upload images
    to the web server, and the server will automatically resize and compress the
    images. It lets users to upload maximum 5 images at one time. The system
    works fine. But sometimes a very strange problem occurs. When the users
    upload the image, the images are able to be uploaded to the system
    successfully, but the system is hanged on the image compression stage. The
    system message returns that the uploaded images are under compression, but
    never ended, even one hour.
    
    I have checked the system log and find there is nothing mentioned in the log
    file. This problem doesn't happen regularly, but it does happen sometimes.
    
    Please kindly advise me what mistake I have made.

  - Clipped image when g.drawImage(img, -3, -4, this)Hello,
    
    I've created a class (full source code at the bottom)
    which extends java.awt.Component and is supposed to
    represent a playing card. If the card is being dragged,
    I'd like to draw a shadow underneath it. And the card
    itself should be drawn a little bit displaced - to make
    the impression that it has been lifted:
    
    public void paint(Graphics g) {
    if (this == dragged) {
    g.drawImage(shadow, 0, 0, this);
    g.drawImage(cardImg, -3, -4, this);
    } else {
    g.drawImage(cardImg, 0, 0, this);
    }
    }
    
    My problem is however that the cardImg is being
    clipped. Does anybody please have an idea how
    to workaround this?
    
    Thank you
    Alex

  - pattern matching help on logical ORI'm using Java 1.4.2_05 and need some help getting a logical OR to work
    within my pattern matcher.
    
    I'm trying to get both string A and B to be recognized by one pattern?
    String strA = "04/14:03,blahblahblah\u007F";
    String strB = "04/14:03,blahblahblah";
    
    So I'm trying to match:
    Two numerals followed by slash followed by 2 numerals followed by a
    colon followed by 2 numerals followed by a comma followed by anything
    followed by a one or 0 delete character OR the end of the line/string.
    
    Here is the regex:
    Pattern.compile("[0-9]{2}[\u002F][0-9]{2}[\u003A][0-9]{2}[\u002C].+[\u007F?]|[$]",
    Pattern.DOTALL);
    
    The logical OR doesn't work though. And I've tried the OR a few other
    ways as well.
    ... [\u007F|$]
    ... [\u007F?|$]
    ... [\u007f]?|[$]
    These don't work either.
    
    I'd appreciate any suggestions.

    so that I don't have repeating lines in my loop. Any help is much
    appreciated.

  - JFrame to FrontHi,
    
    First of all sorry for my german posting before!
    
    Here is my question in english:
    
    By starting my application I construct a JFrame. By clicking onto a
    JButton on this JFrame, it construct a NON-MODAL JDialog, which gets as
    parentComponent the JFrame.
    Now, if I switch between the Frame and the Dialog, they are correctly
    activated, but the Frame does never come to foreground, i.e. it is ever
    ovelapped by the Dialog.
    
    I tryed with "Frame.setVisible(true)", "Frame.toFront()" and
    "Frame.show()", but unfortunately, it does not work.
    
    Is my desired behavior in this case even possible, or is there only the
    way of setting the parentComponent of the Dialog to null?
    
    Thanks!

  - how to combine paintComponent with add(component)?I have a Java application with several classes that extend JPanels and
    that, till now, didn't have any internal Swing components. They did
    display text that was antialiased and sometimes animated by overriding
    paintComponent in each of these custom classes. And this worked fine.
    
    But now on one of the panels I want to add in the northeast corner
    another customized JPanel extending object. When I just call
    basePanel.add(newPan) the newPan would show up when first displayed
    but then dissapear the next time repaint() is called on the basePanel.
    I imagine I have to do something in the basePanel's paintComponent
    method to make sure the new panel is repainted every time. But I'm not
    sure how that is handled. Anyone have some advice? Maybe a quick
    example?

  - gray boxes instead of the appletHi all,
    
    I'm a newbie, so if I should be posting this to a different group, please
    (gently) tell me which one.
    
    I have copied a very small Java applet source off the web and successfully
    compiled it. I have taken the resulting Java classes and put them on my
    website, using the <applet> html tag. The applet works great for me.
    
    However, most of the people I work with just get a gray box where the applet
    should be. (Others can see and use the applet just fine.) The gray box
    *does not* have a red X in it. I can detect no pattern whatsoever in the
    clients for whom the applet does/doesn't work.
    
    The most mysterious part to me is that even people who do not see the applet
    correctly on my website seem to be able to see and use the same applet just
    fine on the site I acquired it from. As far as I know, it's identically the
    same applet. (I just stole the source and compiled it.) This would tend to
    rule out a problem on the client side, but I can't be sure.
    
    I think I've been able to deduce that the problem is not with the location
    of the Java classes on my web page; otherwise, there would be a red X in the
    upper-left corner of the gray box, right? (And in that case it probably
    wouldn't work for anyone, including me.)
    
    Anyone have a clue what's going on? What other information can I provide?
    
    TIA,
    Gnome

  - [SWT] How to enable and disable windows correctly, if using dialogs?Hi,
    
    I am programming a configuration gui for a hardware simulator. There I
    wrote some gui elements, which enable the user to set up some
    parameters used by the simulator.
    
    For example it is possible to enter values in textfields. I do a check,
    if the entered value even is an int, and if not, I create a short error
    message. For example like this:
    
    textwidth.addModifyListener(new ModifyListener() {
    public void modifyText(ModifyEvent e) {
    try {
    width = Integer.parseInt(textwidth.getText());
    } catch (NumberFormatException nfe){
    if (!textwidth.getText().equals("")) {
    width = 0;
    ErrorHandling error = new ErrorHandling(
    "Please enter numbers only!\r\nWidth is
    reset to 0.",
    selscomposite.getShell());
    textwidth.setText("0");
    }
    }
    //modify the scale so it represents the entered value
    scalewidth.setSelection(scalewidth.getMaximum() - width
    + scalewidth.getMinimum());
    }
    });
    
    textwidth is the textfield, representing the value chosen through a
    scale and enabling the user to enter a value manually, and the
    scale-representation is updated if done so.
    
    ErrorHandling is the class I use throughout the project to display
    small error messages. It looks like this:
    
    public class ErrorHandling {
    
    Shell error;
    Shell parentshell;
    
    public ErrorHandling(String errormessage, Shell shell) {
    
    //shell displaying the errormessage
    error = new Shell(SWT.TITLE | SWT.BORDER);
    error.setText("User input error");
    //the layout for the error shell
    FillLayout filllayout = new FillLayout(SWT.VERTICAL);
    filllayout.marginHeight = 5;
    filllayout.marginWidth = 5;
    filllayout.spacing = 3;
    
    error.setLayout(filllayout);
    //disable the parent shell
    parentshell = shell;
    parentshell.setEnabled(false);
    
    //set the errormessage
    CLabel errorlabelmessage = new CLabel(error, SWT.CENTER |
    SWT.SHADOW_IN);
    errorlabelmessage.setText(errormessage);
    
    //a button to close the errormessage
    Button errorreceived = new Button(error, SWT.PUSH |
    SWT.CENTER);
    errorreceived.setText("Ok, i got it!");
    errorreceived.addSelectionListener(new SelectionAdapter() {
    public void widgetSelected(SelectionEvent e) {
    parentshell.setEnabled(true);
    error.close();
    }
    });
    
    //create the errorshell
    error.setActive();
    error.pack();
    error.open();
    }
    }
    
    parentshell is needed, so I can disable the shell, in which the error
    occured until the user hast closed the errormessage by using the "Ok, I
    got it!"-button. I don't even know if this is good style, but it's all
    I know to do so far. I need to have a new shell-variable (e.g.
    parentshell), because otherwise I could not use it in the inner class
    within the listener-context. This leads to the first question: Is there
    no better way to handle this, but the new Object "parentshell"?
    
    The second problem with this implementation is, that if I do not use
    the SWT.BORDER and SWT.TITLE constants within the initialization of the
    error-Shell-object, the small window displaying the error message looks
    real crappy. The title and a window border is needed, but if I have
    those, I also have a close-button on the upper right of the window.
    Because a disabled the parent shell:
    
    parentshell = shell;
    parentshell.setEnabled(false);
    
    I have to enable it, if the error message is closed. I am able to
    enable it, if the user choses the button, but if the user closes the
    window by the close-button of the window-manager, the parent-shell
    never ever gets accessible, because there never came a command to
    enable it again.
    
    A last few words: I tried several constants in the creation of the
    error-Shell-object, but most of them (like ON_TOP, or several modal
    state specifiers) only have the effect, that the error-message has no
    border and no title any more. I am using Linux and the X-Server, so I
    don't know what the behaviour of these constants would be on other
    window-architectures.
    
    Now this was a whole lot of information, but ask me, if you want to
    know something more specific. Any comments are welcome, even those,
    telling me what I have done is totally crap and I should do it like
    this or that.
    
    Thank you in advance!
    
    PS: Sorry for any errors and the bad english.

  - Question about binary release licenseHi,
    
    I hope I'm wrong, but does the license of binary jdk/jre
    released by FreeBSD Foundation prohibit redistribution
    of the package ? I think that Sun allows one to redistribute
    at least jre with application so why is this different ?

  - ligatures in Java 2DI've been trying to work out how to get Java to handle ligatures such
    as "fi" correctly, but without much success. Various online documents
    have suggested that I need to be intervening in the rendering process
    and laying out my own GlyphVectors based on information associated
    with Fonts, but I can't find out the details I need to actually do
    that systematically.
    
    I have discovered (<http://mindprod.com/jgloss/ligature.html>) that
    'fi' has its own code point (\ufb01) in Unicode - should I be manually
    checking whether my Font has specific glyphs for such ligatured
    characters and manually substituting them into my char[] to feed to
    layoutGlyphVector? Do Fonts come with lists of ligatures they
    support, and if so how do I get at them?
    
    And most of all, what is TFM that I am currently foolishly neglecting
    to R?

  - How to get the return value by a Sybase stored procedureSuppose I have the following dummy stored procedure on Sybase or MS
    SQL Server:
    
    create procedure foo
    as

    return 12345
    
    With jdbc driver, how can I get both "Hello World" and 12345 back? Or
    can I get the return code back at all? Do I have to use output

  - XAResource implementation besides of DB and JMSHi All,
    
    When I read article about JTA, the most commonly used XAResource
    implementation is for either DB or JMS. I'm wondering if there's any
    other type of XAResource is really meaningful or useful to be cretaed
    at all. If you have experience making any XAResource besides of DB and
    JMS, would you please share your knowledge. It would be great if you
    can tell what kind of XAResource you have created and where it is used(
    from both business and coding point of view ). It will be even better
    if you can share idea about how the new XAResource is implemented.
    Thanks!

    I want to release some free source code, but not all code is done by
    me. (ex: I use some code from others into my project... )
    
    I think it is too complicate to check every function/routine belongs to

    Thank you very much.

  - MouseEvent problem in JPopupMenuI'm having trouble getting a MouseEvent to get fired for mouseReleased
    to fire in any component added to a submenu of a JPopupMenu in Java 1.5.
    The same code works fine in 1.4.
    
    Here's some simple code to demonstrate the problem. When clicking the
    final button, it stays down and "released" is never printed by the
    listener. Under 1.4, the button is fully operational, and "released" is
    printed. The other two events (clicked and pressed) work fine in either
    version.
    
    Any ideas what's going on here? Any suggested work-arounds? The real
    application where I observed this has a rather complex custom component
    placed in a submenu of a JPopupMenu, and mouseReleased is needed for it
    to work properly.
    
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import java.awt.event.MouseEvent;
    import java.awt.event.MouseListener;
    
    import javax.swing.JButton;
    import javax.swing.JFrame;
    import javax.swing.JMenu;
    import javax.swing.JPopupMenu;
    
    public class BugTest extends JFrame
    {
    private MouseListener ml = new MouseListener() {
    public void mouseEntered(MouseEvent e) { }
    public void mouseExited(MouseEvent e) { }
    
    public void mouseClicked(MouseEvent e)
    {
    System.out.println("clicked");
    }
    
    public void mousePressed(MouseEvent e)
    {
    System.out.println("pressed");
    }
    
    public void mouseReleased(MouseEvent e)
    {
    System.out.println("released");
    }
    };
    
    public BugTest()
    {
    super("Test Popup mouseReleased");
    
    JButton startButton = new JButton("Start");
    
    startButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)
    {
    JPopupMenu popup = new JPopupMenu();
    JMenu middleMenu = new JMenu("Middle");
    JButton endButton = new JButton("End");
    
    endButton.addMouseListener(ml);
    
    middleMenu.add(endButton);
    popup.add(middleMenu);
    popup.show(BugTest.this, 20, 20);
    }
    });
    
    getContentPane().add(startButton);
    pack();
    setVisible(true);
    }
    
    public static void main(String[] args)
    {
    new BugTest();
    }
    }

  - Java code obfuscationHey all,
    I'm looking at using a tool to obfuscate some java code and have a 3
    part question:
    
    1. If price were not a factor, what obfuscator would you use?
    2. If price were a factor and you wanted a midrange cost product (say
    under $500) what obfuscator would you use?
    3. If you wanted a free obfuscator which one would you use?
    
    Something of note about my product is that there is a fair amount of
    reflection going on as I do a lot of dynamic class loading. I've played
    around with RetroGuard, and while it's nice, the script creation looks
    like it will be quite painful with the amount of reflection I'm going to
    have to work with. Anyway, I'd appreciate any thoughts you might have.
    
    Thanks.

  - Trouble with reading and appending to lines in a file...Hi there,
    
    Please bare with me on this, I'm a newbie :o). Ok, I'm trying to read a
    file (a bunch of 1 word lines), find the last line with the word "SKIP" at
    the end, and get the next line. After getting the desired line, I want to
    append the word "SKIP" to that line as well and save and close the file.
    
    I also want the class to have an input parameter (integer), which will be
    the same name of the file (example: input = 1234 --> filname = 1234.txt).
    
    Here is what I've got so far:
    
    import java.io.*;
    public class GetLine {
    int number; //let's say the lines in the file are all 5 digit
    numbers, with no spaces
    public boolean evaluate(String str) {
    //
    //I'm not sure how to evaluate if the end of the line
    has the word SKIP and the following doesn't work????
    //
    if ( StringBuffer.indexOf("SKIP\n") )
    return true;
    }
    
    public void get(int c) throws IOException, FileNotFoundException {
    String line;
    boolean b;
    FileReader fr=new FileReader(number + ".txt");
    BufferedReader br=new BufferedReader(fr);
    while((line=br.readLine())!=null )
    {
    b = evaluate(line);
    if (b==false)
    {
    //
    //not sure if I can just do a "return
    line" to get the first line found without SKIP???
    return line;
    //
    //not sure if I can do the following
    either???
    //
    line = line + "SKIP";
    
    }
    }
    }
    }
    
    Please, any suggestions are apprciated. Thanks for your help.
