  - Good JDO tutorial ?I'm trying to learn JDO and am having a tought time getting started.
    I'm using Eclipse and have downloaded the Triactive JDO. (It seemed
    rated pretty well and it's free)
    I'm using SQL Server
    I'd prefer not to use enhancement because it doesn't sound like the
    right approach, but I guess I could try it if the tutorial was good
    
    Can someone point me in the right direction? I don't mind trying a
    different JDO (as long as it is free). But I want to go against sql server.

  - Applet paint problem (only on IE)I've written an animated, double buffered graphical applet for JDK 1.1.8 (It
    has to run without the user having to download a new JRE) that is run in a
    table cell on a web page. It uses threads for the animation, with a delay
    based on the speed of the animation.
    
    The problem is that on IE, the image does not display until it regains
    focus, ie the page is scrolled down, then up, or a second window obscures it
    and is then removed. According to the Java console, it has started fine.
    
    It works as it should on FireFox and Opera, and works in IE when it is the
    only thing on the page. I have tried everything I can think of (removing the
    delay, extra repaints, trying every kind of embedding into the web page,
    etc, even trying to get keyboard focus) but to no avail.
    
    Does anyone know what the problem might be?
    
    Thanks,

  - <<Whats this? >>Help ButtonDear All
    
    In most windows based applications, we can find a button with icon like
    [Arrow and Question mark]
    It is always on the help menu
    When selected the Cursor is changed to that icon, and any thing clicked
    will pop-up a small yellow help tip
    
    How can this be done with java?

    the anecho/plugin directory was created by JamochaMUD.jar. do I need to

    leave the JamochaMUD.jar intact and simply work from TestPlugIn.java in
    ../anecho/plugin ?

  - Help building applicationHello,
    
    I am fairly new to Java. I recently switched from C++ to Java for a
    project I am working on. I was looking for a decent HTML parser when I came
    across the htmlparser 1.5 project on Sourceforge.net. I understand the
    logic, but I am having build problems with my own classes. If I put my class
    in the jar file along with all the other parser classes, everything works
    well, but I prefer not to do it that was. When I have a separate .class file
    and try to run it through the JVM I get the following error:
    "java.lang.NoClassDefFoundError: AdamParser (wrong name:
    org/htmlparser/AdamParser)". All I want to do is test my ideas the simplest
    way possible. I was hoping some more experienced Java programmer could help
    me.
    
    TIA,
    Adam

  - New technology, old idea.... why not?Good Morning/Evening,
    
    I'm young and foolish but love to create new ideas. The one I am
    currently pondering...... (a simple unoptermised version of it):
    
    public void wastefulSort()
    {
    //Using todays technology, of a lot of unused space
    int[] A = {5,4,3,2,9};
    int[] B = new int[1000];
    
    for(int i = 0; i < A.length; i++)
    {
    B[A[i]] = A[i];
    }
    
    }
    
    Assumptions:
    This is run on a turing machine.
    The input values do not repeat.
    Assume any B space unused, it is null (not 0).
    -------------------------------------------------
    
    Is this not the quickest way of sorting numerical data? aka takes n
    (or O(n))?
    
    Thanks,

  - it seems like my scene is empty :(I'm a beginner. I know nothing more than I read in some tutorials. So
    pelase be patient and forgiving ;-)
    
    So when I try to construct the scene, the only thing I see is black and
    probably empty area :( My code is similiar to what I've seen in those
    tutorials but it simply isn't working, while the examples I tried gave
    good results. This is code of my createScene function:
    meshX and meshY are constants. int intensity[][] keeps values of y
    coordinates. These values can generally be anything between 1 and 255.
    
    public BranchGroup createScene()
    {
    TransformGroup tg = new TransformGroup();
    BranchGroup objRoot = new BranchGroup();
    TriangleArray tri;
    
    for(i=0;i<meshX-1;i++)
    for(j=0;j<meshY-1;j++)
    {
    tri = new TriangleArray(3, TriangleArray.COORDINATES);
    Shape3D shape = new Shape3D();
    tri.setCoordinate(0, new Point3f(i+1, intensity[i+1][j], j));
    tri.setCoordinate(1, new Point3f(i, intensity[i][j], j));
    tri.setCoordinate(2, new Point3f(i, intensity[i][j+1], j+1));
    shape.setGeometry(tri);
    tg.addChild(shape);
    Shape3D shape2 = new Shape3D();
    tri = new TriangleArray(3, TriangleArray.COORDINATES);
    tri.setCoordinate(0, new Point3f(i+1, intensity[i+1][j+1],
    j+1));
    tri.setCoordinate(1, new Point3f(i+1, intensity[i+1][j], j));
    tri.setCoordinate(2, new Point3f(i, intensity[i][j+1], j+1));
    shape2.setGeometry(tri);
    tg.addChild(shape2);
    
    }
    
    Transform3D cc3d = new Transform3D();
    cc3d.setTranslation(new Vector3f (0f ,0f ,10f ));
    tg.setTransform(cc3d);
    objRoot.addChild(tg);
    
    return objRoot;
    }
    
    can you help me?

  - Finding file inside jar or zip fileIf I want to find whether a file test.java exists in my c:\ directory,
    I do
    File f = new File("c:\test.java");
    f.exists();
    
    But if I have that test.java inside a zip file or jar file, how do I
    find it's existance? I tried doing
    File f = new File("jar:c:/data.zip!/test.java");
    f.exists();
    
    It didn't work. It always return false.
    
    Does anyone have any idea on how to find the existance of a file inside
    a zip or jar file?
    
    Thanks,

  - Create own data structure from DOM?Hi again!
    
    I successfully parsed my XML file into a DOM and traversed it in level-
    order. I did that to gather information about component number and
    level of each component node in the tree, because I need to work with
    that information a little later.
    
    The original XML file looks a little like this (the attribute index
    letters represent the level-order "numbering"):
    
    <Component ind="A">
    <Component ind="B">
    <Component ind="D"/>
    <Component ind="E"/>
    </Component>
    <Component ind="C">
    <Component ind="F"/>
    </Component>
    </Component>
    
    What I'm trying to do now is to create instances of each component. I
    have a Component class carrying all information I need - except one:
    Who's my father component?
    
    What should I do to tell every component instance of it's father node
    without creating more than one instance of each component?
    
    I thought of two and a half possibilities yet, but I really hope you
    can help me here or give me some new ideas:
    
    a) put every component node (from DOM) onto a stack and pop one by one
    by creating component instances and create another component instance
    of node.getParent(). but then I have a lot of component instances
    doubled or tripled or even more... that ain't really efficient.
    
    Stack:
    F
    E
    D
    C
    B
    A
    
    b) create instances while traversing the DOM and add each instance to
    a array list. But then I have the problem of not knowing the array
    index of the father component.
    
    Array:
    A B C D E F
    
    c) create multiple lists with array[0] carrying the father node
    followed by it's child nodes (array[i])
    
    Array 1:
    A B C
    
    Array 2:
    B D E
    
    Array 3:
    C F
    
    Thank you in advance!

  - Simultaneous keypresses in Pong gameHi,
    i have created a Pong game Application where two players control their
    pads using the keyboard. the problem is that one player is using the
    action keys
    VK_UP and VK_DOWN in keyPressed() and the other, characters 'w' and
    's' in keyTyped(). when both players hit a key simultaneously and keep
    it pressed then only one of the two pads move. on the other hand if
    both hit their keys fast then everything works ok. i declared both
    keyPressed and keyTyped as "synchronized" but it doesn't seem to work.
    what can i do in order to process them simultaneously? there is a run
    method in my application as well.

  - Locator2 and SAX parsersHello:
    
    I'm using the org.xml.sax JAVA API to manage a XML file.
    
    I want to know if it exists a SAX parser ( SAX driver ) that supports
    Locator2 interface (in org.xml.sax.ext package ).
    
    My objetive is to get the encoding property of a XML file, and that
    interface has a getEncoding() method.
    
    Anyone SAX parsers that I've probed don't supports this interface (xerces,
    piccolo, oracle , aelfred, ... )
    
    I would like to know if somebody has used this JAVA interface (Locator2).

  - loop through all controls on a panel without hardcodingHello,
    
    In other environments (Delphi and .NET have things like ComponentCount
    and FindControl) I've used prior to Java, I could automatically find
    all the controls (or only the controls of a certain type, like
    checkboxes for example) on a form by passing that form off to some
    built in methods which know how to iterate through all the controls
    contained within that form.
    
    I haven't been able to find an equivalent feature in Java. In my Java
    app, if I have 5 checkboxes on a panel, I would prefer to pass just
    the panel to my method for processing (and have checkbox state
    determined there) rather than myMethod (cb1, cb2, cb3, cb4, cb5).
    
    How is this done in Java?
    
    Thanks!

  - Launching a browser -- help!I've found several good examples out there on how to launch a web
    browser
    from a Java application, using the Runtime exec() command. However,
    what
    I'd like to do is configure the browser that's launched, as one would
    in
    an html link with the javascript onclick="window.open(
    'http://www.mysite.com', 'mywindow',
    'width=500,height=500,scrollbars=no,resizable=no')"
    
    Is there any way to set, for example, the width and height on the
    browser
    I launch? There doesn't seem to be any command line parameters for
    the
    browser I'm launching, and besides, those would be platform-specific.
    I
    suspect it will require some javascript trickery -- but I only know
    how
    to specify those parameters on links, not on the page I'm am newly
    invoking...
    
    Please help!

    It's not exactly doing very much.

    How about generating the necessary C++ functions at build time, that all
    just delegate to their Java counterparts? Shouldn't be too hard with Ant
    and XDoclet, I reckon. Just tag the relevant methods and use a custom
    doclet.

  - Threading In Java BeansHello, I was trying to find some information regarding Concurrency in
    J2EE. In my application I simply put a lock on the session and the
    accessor/mutator methods inside the bean. Is this the proper way of
    ensuring data consistency in a large scale web site. Any opinions or
    links would be appreciated.
    thanks

  - [ANT] apply-task and relative attribute (gettext-like internationalisation/localisation)Hello,
    
    We are currently trying to internationalise Jmol with gettext. Therefor I
    wrote an ant-build-script to generate everything necessary to allow the
    typical use of gettext. You will find it here:
    
    http://cvs.sourceforge.net/viewcvs.py/jmol/Jmol/build-i18n.xml?rev=1.7&view=auto
    or http://pastebin.com/291187
    
    But I have a minor problem. At the moment xgettext gets all files relative
    to the src-directory (${basedir}/src), which leads to such .po(t)-file
    location-entries:
    
    #: org/jmol/applet/Jmol.java:118
    
    but I would like to have entries relative to the directory, where the .pot
    and .po files reside (${basedir}/src/org/jmol/translation/Jmol):
    
    #: ../../../jmol/applet/Jmol.java:118
    
    Is there anyone with an idea, how this can be realized (I wasn't
    successful in my last tries)? You can also reach me via IRC
    (irc.freenode.net, #cdk) or ICQ (#148295333) for a direct discussion
    and/or work on the file at pastebin.com. Of course, I will also send all
    discussion results to the group.
    
    BTW: Ant is version 1.6.2.
    
    Regards, Daniel

  - Design pattern for 1 Producer/multiple Consumers?I'm doing a simple Producer/Consumer thing based on the example in the Sun
    docs, where the Consumer does a wait until there is something to consume,
    then it consumes it and does a notify, and the Producer does a wait until
    there is nothing to consume and then adds it and does a notify. But now I
    need a bunch of Consumers. Is there a standard design pattern for this,
    or am I going to have to figure it out myself?

  - Media Framework presenceHello,
    
    Applications produced by my project, sometimes (not always) relys on
    the presence of the Media Framework on the machine of the final user.
    When an application created with my project uses Media framework, is
    launched on a machine where JMF is not installed, it crashes badly
    (hard reset necessary).
    So my question : is there a way to detect if the JMF is installed on
    the machine of the final user?
    
    Thanks for you input,
    
    Francois
