  - Hibernate on delete cascadeI use Hibernate and I am not able to do cascade delete.
    
    After I create a project I have:
    
    select * from project;
    uid | name | shortdescription
    -----+------+-----------------
    1 | nc | NC Web application
    (1 row)
    
    After I subscribe to the project I have:
    
    select * from subscription;
    uid | account | project | role
    -----+---------+---------+------
    1 | 1 | 1 | 1
    (1 row)
    
    When I delete the project with a simple session.delete
    
    try {
    session.delete(project);
    session.flush();
    } catch (HibernateException e) {...
    
    the row is deleted in the table "project"
    but the row stays in table "subscription". Only the column entry "project" is set to null.
    
    select * from subscription;
    uid | account | project | role
    -----+---------+---------+------
    1 | 1 | | 1
    (1 row)
    
    I want the row to be deleted, how do I do that?
    
    My two tables one for Projects and one for Subscriptions
    
    <hibernate-mapping>
    
    <class name="org.cobra.persistence.Project" table="project">
    
    <id name="id" column="uid" type="long">
    <generator class="increment"/>
    </id>
    
    <property name="name">
    <column name="name" sql-type="char(32)" not-null="true"/>
    </property>
    
    <property name="shortDescription">
    <column name="shortDescription" sql-type="char(256)" not-null="true"/>
    </property>
    
    <set name="subscriptions" table="subscription" cascade="all-delete-orphan">

  - Anyone using Studio 4 with MSAccess as DBMS?Is anyone using the Studio4 (Community version, Windows NT) IDE for
    building forms using an MS Access database to supply a JTable via
    net.beans palette components (nBCachedRowSet or nJcdbRowSet)? (Using
    the JDBC-ODCB bridge). I can succesfully connect and initialize
    components--can see the tables and columns in the Runtime explorer
    connection--but when I execute the form, all columns are blank.
    
    Also, when GUI editing, if I try to set the TableModel using the
    TableEditor tab and select the nBCachedRowSet component, I get the
    following error: "Unable to fetch columns; SQL-server rejected
    establishment of SQL-connection. PointBase." Why is it still looking
    at Pointbase?
    
    Here's how components are set:
    connectionSource1
    Database URL = jdbc:odbc:IM_EDITOR (this works with MSQuery, so ODBC
    is good)
    Driver = sun.jdbc.odbc.JdbcOdbcDriver (ok here)
    nBCachedRowSet1
    command = select * from IM (this also works in MSQuery)
    Database URL = jdbc:odbc:IM_EDITOR
    jTable1
    selection Model = nBCachedRowSet1
    
    Need more code?
    
    I give up! I really want to use Access for the DBM due to other
    issues, but I am running out of patience!
    TIA
    Frustrated...

  - servlet and threadi am connecting to a servlet. i am passing some values from JSP to
    servlet. the servlet gets those values from JSP by
    request.getParameter(). then the servlet creates Threads as much as
    values gives to it.
    
    if the servlet is given 3 values from the JSP, then it would create 3
    threads to calculate.
    
    if the servlet is given 10 values from the JSP, then it would create 10
    threads to calculate.
    
    each Thread would return results to the JSP.
    
    PROBLEM :
    =========
    
    how does my JSP would get the results from the threads. JSP would
    refresh in 5 secs interval and would display the latest threads result.

  - McDonalds/RoundTable, design&farm (was: I'm still waiting for ...)> From: email***@***.com (Michael Sullivan)
    > ... instead of looking for exactly and precisely the kind of work
    > that you have done in the distant past, ...
    
    You're displaying a serious misconception. I'm available for any legal
    work where I'd be doing something actually useful so that it would be
    worth paying me to do it. It's the employers who refuse to even
    consider people who haven't done exactly the same kind of work before.
    
    > Go work at McDonalds
    
    I tried that, when I had less than one year work experience. The
    manager at the McDonalds on El Monte near El Camino Real told me that
    because I have a college degree he won't consider me for employment
    because he'd waste two months training me and then I'd find a better
    job elsewhere and he'd be out the expense of training. Later that year
    I got a job at Round Table Pizza on University in Palo Alto, where a
    ditzy redhead Mrs. Masinter wasn't watching where she was going and
    collided with my car and then freaked out seeing the car parts strewn
    on the pavement, apologizing, exchanging insurance info, then she drove
    off before giving me a chance to inspect the damage and see that all
    the damage was to *her* car, not mine. Anyway, Round Table fired me
    because I suffer a learning disability, unable to memorize the prices
    on the menu. A year or two later I was sitting at a terminal at the
    A.I. lab doing my usual work for free, and occasionally running FINGER
    to see who else was around, when I saw Larry Masinter logged in, so I
    wwnt over and asked if he was in any way related to that ditzy driver,
    and indeed that was his former wife. He showed me Lisp for the first
    time, impressed me, and after Hans Moravec explained the REP loop to me
    I was forever going strong with Lisp.
    
    > or a factory
    
    That's not a good idea. I have very poor muscle coordination, can't
    write legibly, can't do sports at all, take ten times as long as anyone
    else to do a simple mechanical task in metal/wood shop in school and
    still the result is cruddy, need extra space on both sides of car when
    I'm driving because I can't judge distance between car and parket cars,
    break almost anything physical I try to work on, did I tell you about
    the disaster when I tried to do work on my car (tune-up, and lubricate
    the air-duct wire-in-sleeve control cables)?
    
    > a lot more brainpower goes into defining the problems that explicitly
    > than into the actual coding,
    
    Much of my work at Stanford was like that. Unfortunately there's no way
    to express that with buzzwords on a resume, so you're not aware of that
    from reading my resumes.
    
    > and once you've done that part -- Indians and Chinese can and will
    
    I'd be glad to design the software, farm it out to I&C, then check what
    comes back to make sure it does the job that was required. Do you know
    any such software-design jobs available now? I've never seen any such
    jobs advertised anywhere, ever in all the years since I started
    programming.

  - Returning value from deep recursionI have the following code
    
    ***********************************
    /**
    * Recurses through schema finding the first instance of the
    element name
    * @param schemaElement - current element being compared from
    schema
    * @param checkElement - element to be checked against i.e. the
    node selected in the gui
    * @return the element in schema which matches the checkElement
    */
    private Element findElementNameMatch(Element schemaElement, Element
    checkElement)
    {
    // Get list of children
    List listOfChildren = schemaElement.getChildren();
    
    // If element has children
    if(listOfChildren.size() != 0)
    {
    // Recurse through all elements under this one
    for(int x=0; x < listOfChildren.size(); x++)
    {
    // Get child element
    Element childElement = (Element) listOfChildren.get(x);
    
    if(childElement.getName() == checkElement.getName())
    {
    return(childElement);
    }
    findElementNameMatch(childElement,checkElement);
    }
    }
    
    return(null);
    }
    ***********************************
    
    The method is trying to find an element in an xml document that matches
    a given name.
    
    Can anyone give me tips on how to go about returning a value from deep
    recursion to the first recursion of that particular method, so it can
    return that value to the method that called it.
    
    And also quite importantly how to stop any recursions after a match has
    been found. EG a target element is found and returned, but how can i
    stop the recursion going on to check elements under this element.
    
    So far i have only achieved the two by creating a global variable and
    flag, the variable is initialised when the match is found, and flag is
    set to true so no more recursions are done afterwards.

  - Memory Leakage drawing Images from Stream - Minimum exampleOk folks
    
    I posted this a number of times ago,but never posted a minimum code
    example for people to look at.
    
    I was trying to load and draw images from a Mjpeg-Stream, reading from
    the stream in a different thread.
    
    This is the thread where the images are read by:
    
    public class Axis2420
    {
    
    private HttpURLConnection hurlconnection = null;
    private DataInputStream datainstream = null;
    private String serialNumber = null;
    private boolean connected = false;
    private Frame dummy = null;
    private Image image = null;
    private String MJpegStreamUrl = null;
    
    Runnable decodingThread = null;
    
    public void SetURL(String url)
    {
    MJpegStreamUrl = url;
    }
    
    public boolean Connect()
    {
    
    if(MJpegStreamUrl == null)
    {
    System.out.println("Error: Empty Camera URL String");
    return false;
    }
    
    try
    {
    
    URL streamurl = new URL(MJpegStreamUrl);
    hurlconnection = (HttpURLConnection)streamurl.openConnection();
    hurlconnection.setReadTimeout(10000);
    //hurlconnection.setUseCaches(false);
    
    InputStream instream = hurlconnection.getInputStream();
    
    connected = true;
    
    BufferedInputStream bis = new BufferedInputStream(instream);
    datainstream = new DataInputStream(bis);
    
    } catch(IOException e)
    {
    System.out.println("Fehler");
    
    try
    {
    hurlconnection.disconnect();
    Thread.sleep(60);
    }
    catch(InterruptedException ie)
    {
    hurlconnection.disconnect();
    Connect();
    }
    catch(Exception ex)
    {return false; }
    
    System.out.println(e.getMessage());
    
    return false;
    }
    
    return true;
    }
    
    //run method of the reading thread
    public void run()
    {
    //test if still connected
    if(!connected)
    return;
    
    try
    {
    //decode stream
    if(connected)
    {
    Image i = null;
    //ImageIO.setUseCache(false);
    long before,after;
    
    while(!Thread.currentThread().isInterrupted())
    {
    
    i = null;
    
    String header;
    int k = 0;
    
    do
    {
    header = datainstream.readLine();
    //System.out.println("Zeile: " +header);
    }
    while(++k < 3);
    
    int j = (new Integer(header.substring("Content-Length:
    ".length()))).intValue();
    
    datainstream.readByte();
    datainstream.readByte();
    // datainstream.readLine();
    imageJPG = new byte[j];
    datainstream.readFully(imageJPG, 0, j);
    byte tail[] = new byte[4];
    datainstream.readFully(tail,0,4);
    
    i =
    Toolkit.getDefaultToolkit().createImage(imageJPG,0,imageJPG.length);
    
    image = i;
    i = null;
    
    fireChange(); //calls the stateChanged() method in
    the class 'MainProgram' below
    
    image = null;
    i = null;
    
    Thread.currentThread().sleep(10);
    }
    }
    }
    catch(Exception ex)
    {
    ex.printStackTrace();
    }
    finally
    {
    
    try {
    datainstream.close();
    } catch(Exception ex)
    {
    ex.printStackTrace();
    }
    }
    }
    
    //for the listening objects so they can fetch the latest image
    public Image getLatestImage()
    {
    return image;
    }
    
    <....>
    
    }
    
    Once a new image has arrived, the fireChange() method calls this method
    on the MainProgram class:
    
    class MainProgram
    extends JFrame
    implements Runnable,ChangeListener
    {
    public static String WINDOW_TITLE = "BINO GESTENERKENNUNG";
    public static int WINDOW_WIDTH = 640;
    public static int WINDOW_HEIGHT = 480;
    
    public static final int CAMERA_LEFT = 0;
    public static final int CAMERA_RIGHT = 1;
    
    //public static final String leftCameraURL =
    "http://192.168.1.51/axis-cgi/mjpg/video.cgi?resolution=704x576&compression=25&clock=0&date=1&fps=10";
    
    //public static final String rightCameraURL =
    "http://192.168.1.51/axis-cgi/mjpg/video.cgi?resolution=704x576&compression=25&clock=0&date=1&fps=10";
    
    public static final String leftCameraURL =
    "http://192.168.1.51/axis-cgi/mjpg/video.cgi?resolution=352x288&compression=70&date=1&fps=5";
    
    public static final String rightCameraURL =
    "http://192.168.1.51/axis-cgi/mjpg/video.cgi?resolution=352x288&compression=100&date=1&fps=5";
    
    Image currentLeftImage;
    Image currentRightImage;
    
    Graphics leftImageGraphics;
    Graphics rightImageGraphics;
    Graphics leftCameraGraphics;
    Graphics rightCameraGraphics;
    byte[] currentLeftImageJPG;
    byte[] currentRightImageJPG;
    
    BufferedImage testImage;
    
    Axis2420 leftCamera = null;
    Axis2420 rightCamera = null;
    
    CameraCanvas leftCameraCanvas = null;
    CameraCanvas rightCameraCanvas = null;
    
    Runnable drawThread = null;
    boolean readyToDraw = false;
    boolean newImage = false;
    
    long frameRateLeft = 0,frameRateRight = 0;
    long frameTimesLeft[],frameTimesRight[];
    
    //vPointerDetector leftImagePointer;
    //vPointerDetector rightImagePointer;
    vPointerDetector imagePointer;
    
    boolean updateLeftImage,updateRightImage;
    
    <.....lots of meaningless stuff.......>
    
    public void stateChanged(ChangeEvent e)
    {
    
    currentRightImage = rightCamera.getLatestImage();
    
    rightCameraCanvas.SetUpdate(true); //otherwise paintComponent()
    of the JCanvas won't draw the image
    rightCameraCanvas.SetImage(currentRightImage);
    rightCameraCanvas.repaint();
    currentRightImage = null;
    currentRightImageJPG = null;
    }
    }
    
    }
    
    } //end of MainProgram class
    
    Basically, all the stateChange method does is getting the image from the
    image-reading thread ('rightCamera' of type Axis2420) after
    rightCamera called fireChange(). The image is passed to an object of the
    class CameraCanvas which derieves from JCanvas. After that, we cast
    repaint() on the CameraCanvas (rightCameraCanvas.repaint() ).
    
    This is the CameraCanvas that is responsible for drawing:
    
    public class CameraCanvas extends JPanel
    {
    
    private Image image = null;
    boolean drawNext = false;
    boolean readyForNext;
    
    public void paintComponent(Graphics g)
    {
    if(drawNext == true)
    {
    
    readyForNext =
    g.drawImage(image,0,0,getSize().width,getSize().height,this);
    //image.flush();
    image = null;
    //g.dispose();
    
    //imageBuffered.flush();
    drawNext = false;
    }
    
    }
    
    //indicates that there is a new image
    public void SetUpdate(boolean up)
    {
    drawNext = up;
    }
    
    //passes a new image to the Canvas
    public void SetImage(Image i)
    {
    image = i;
    }
    }
    
    The program draws the stream correctly and is smooth like butter.
    However, there is a HUGE memory leak somewhere that raises the memory
    usage by about 40MBytes per second. If I remove the call to
    
    readyForNext = g.drawImage(image,0,0,getSize().width,getSize().height,this);
    
    in the CameraCanvas thread, the leak will go down to about 40 kbyte /
    second. If I leave it in and post a System.gc() call afterwards, the
    leak will also go down.
    
    I think that I'm somewhat polling the AWTEvent thread which lots of
    copies of images waiting to be drawn. Also using
    Toolkit.getDefaultToolkit().createImage(imageJPG,0,imageJPG.length);
    
    spawns abouth 4 ImageFetcher threads which I think are the reason for
    the small memory leak.
    
    Now the question: What can I do about it?
    
    It seems that the garbage collection isn't called after drawing an image
    and casting it manually via System.gc() slows everything down a lot.
    Using ImageIO.read)() instead of the Toolkit seems to remove the small
    leak, but not the big one for drawing. And it tends to be slower since
    it's blocking and keeping the Axis2420 thread from reading from the stream.
    
    My thesis is due soon, so pleease have a look at it again.!!
    Thanks in advance!!!

java-programmer, API 1.5.0 Download Hi all,
I am new to the Mac and am looking for a download of the
jdk 1.5.0 api. I cannot find a tarball or zip file on the
Sun site that I can download so I can use the reference when
I am offline.

Suggestions?

Thanks,

A better idea would be to read the part where the OP said he's new to
the Mac. IE, that nastiest of all browsers, is long defunct on the Mac,
thankfully.

  - programming the JVMHi,
    
    I'm wanting to program the JVM independant of a compiler by
    emitting bytecodes directly and I have orderd the book by J Engel
    'Programming for the JVM'.
    The lead on this book from amazon is 4-6 weeks which (may?) turn
    into never. Does anyone here have recommendations for alternate
    texts (that are introductory/tutorial in nature, rather than
    reference texts) and websites that may help me with this - so
    I don't just sit kicking my heels while it possibly doesn't arrive?
    I've hunted in most of the obvious places but nothing seems to
    fit the need or cover the topics that the Engel book does
    sensibly.
    
    TIA

  - Is this a ZipInputStream Bug?
    I just got thru tracking down what was happening, but I still don't know
    WHY.
    Im using ZipInput & Output Stream classes to make a compressed file
    (actually it's an image). I create it via ZipOutputStream using a 1K
    buffer for writing i.e.:
    
    ...
    try { // Create the ZIP file
    zos = new ZipOutputStream(new FileOutputStream(zipfname)); }
    catch (IOException e) {
    System.out.println("ZipOutputStream error on open.");
    return null; }
    
    try { zos.putNextEntry(new ZipEntry(imgfname)); }
    catch (IOException e) {
    System.out.println("ZipOutputStream error on put-entry.");
    return null; }
    
    ...
    try { zos.write(bbuf, 0, bix); }
    catch(IOException e) {
    System.out.println("ZipOutputStream error on write.");
    error = true;
    break;
    }
    ...
    
    Here bbuf is 1K.
    
    All is ok - WinZip can extract it and the image is fine. Then I try to
    read it back via ZipInputStream - i.e.:
    
    ...
    try { zis = new ZipInputStream(new FileInputStream(filespec)); }
    catch (IOException e) {
    System.out.println("ZipInputStream error on open.");
    return pixels; }
    
    try { zent = zis.getNextEntry(); }
    catch (IOException e) {
    System.out.println("ZipInputStream error on get-entry.");
    return pixels; }
    
    ...
    while ( cnt > 0 ) {
    try { rcnt = zis.read(bbuf, rcnt, cnt); }
    catch(IOException ex) {
    System.out.println("ex: " +ex.getMessage());
    error = true; }
    cnt -= rcnt;
    }
    ...
    
    Here is where the problem occurs. If bbuf is 128 or 256 bytes the image
    returns just like it should. But if I increase it to 1K junk starts to
    show up within the picture at 4K the picture is barely viewable because
    of the junk and at 32K I get ArrayOutOfBounds exception during the read
    (NOT related to my code). I've verified that the "junk" is data that did
    not come out of the zip, the way it went in.
    
    I'm running JDK 1.3.1 on an NT4.0 platform.
    
    Have others seen this behavior ?
    Any ideas on why ?
    
    TIA

  - JGoodies JLabel with multiple linesHi
    
    I use JGoodies Forms to create a GUI application. I need to show a simple
    multiline description in the window. I use JLabel with html text like
    "<HTML> ... my description ... </HTML>".
    
    Because it's multiline, java never knows how much lines it contains and what
    is initial height of that component. When I add this do panel and show on
    the screen, my frame has to small height and hides some components. General
    problem is that I use different fonts (almst blind user can select bigger
    fonts).
    
    code:
    -------------------------------
    FormLayout layout = new FormLayout("fill:500px", // kolumny
    "p, 10px, p, 10px, p, 7px, p, 7px, p, 10px, p"); //
    wiersze
    
    PanelBuilder builder = new PanelBuilder(layout);
    builder.setDefaultDialogBorder();
    CellConstraints cc = new CellConstraints();
    
    ...........
    builder.add(textArea, cc.xy(1,3));
    ...........
    getContentPane().add(builder.getPanel());
    pack();
    
    Can anyone help me ?

  - static reference in a non-static methodI'm trying to run a simple program that read info from a file and
    displays it on the screen. However, I am constantly getting the
    following error.

    ==================================================================================
    
    I don't want to declare any variables static since I don't think I

    ================================================================
    File myFile = new File("Info.txt");
    Scanner tokenizer = new Scanner(myFile);

    I was getting a similar error when I was trying to read in standard
    input from the user i.e. using input stream reader and buffer

    Can anyone please help?

  - model to xmlHi,
    
    We have "Objects" that relate to each other in a parent-child
    relationship. Also these objects can have references to ther objects
    that is not a parent. Let me give you all an example.
    
    I have the following parent-child relationship between objects,
    
    Object A=1
    |
    -------------
    | |
    Object B=1 Object C=1
    |
    -------------
    | |
    Object D=1 Object D=2
    
    Note: The number is the identity when we have more than one object of
    the same type.
    
    "Object A=1" is parent to child "Object B=1".
    
    We have the same relationship for "Object D=1". "Object A=1" is parent
    to "Object B=1" which is parent to "Object D=1". The path to "Object
    D=1" is "Object A=1,Object C=1,Object D=1".
    
    Also "Object B=1" can have a reference to "Object D=2". The
    "reference"-attribute in "Object B=1" has the following path,
    
    "Object A=1,Object C=1,Object D=2"
    
    My question is if there is a tool where I can graphically create my
    model ( see my nice one !!!) and from that generate an xml file ( or
    xmi).
    
    Requirements:
    * It is important that when I create "Object B=1" it must be possible
    for "Object B=1" to know that it's parent is
    "Object A=1". When the hirarchy grows the child at the end should know
    the whole path to itself.
    
    * It is also important that a reference to an Object D=2 is created as
    "Object A=1,Object C=1,Object D=2"
    
    Has anyone done something similar? Any open-source tools for this? All
    ideas/questions are welcome.
    
    BR

  - starting a weblogic servlet?Hello,
    I have written a basic servlet of the form
    
    public final class MyServlet extends HttpServlet
    {
    public void init(ServletConfig config) throws ServletException
    {
    super.init(config)
    /* do other stuff */
    }
    
    }
    
    My question is, what do I need to do so that the "init" method is
    invoked upon servlet (i.e. Weblogic) startup? I'm using Weblogic 5.1
    sp 12 on Sun Solaris.

  - IndexOf for whitespaceWhat if you wanted the indexOf either a space or a \n whichever came
    first. Have you a slick way to code that?
    
    Pedestrian possibilities include:
    
    1. pair of indexOfs , take minimum ignoring <0s.
    
    2. Write a loop that uses charAt
    
    3. write a regex
    
    Is there a slick way to handle it?

  - java vs ircHi
    Im at a crossroad as to how to implement a webchat. I have the option of
    building a chat using a standard IRC server saving me the trouble of
    implementing it myself, OR i can write the server myself in Java giving me
    full customizability. I would tend to go with the latter approach however im
    rather concerned about performance. By performance im thinking bandwidth and
    server load. So my question is: is it possible to build a chat server in
    Java that is
    a) better or equal to an IRC server utilizing bandwidth, and
    b) better or equal to an IRC servers server load?
    Im thinking performance wise that IRC would be better, but im not sure
    whether this is true so im asking if anyone can give me some input as to why
    one solution would be better than the other.
    
    Thanx
    Mike
