  - Array List IssueI have been having this unique issue with Array List I am trying add
    say about 10 Objects in an Array List and conevr that to an Array.
    Later when I parse through the Array i am having an Array of length 10
    however i am only having the same element for all the 10 of them. can
    anyone out there throw some light onto what i am doing wrong here here
    is the peice of Code I am using
    
    Course course = null;
    
    for(int i=0;i<10;i++){
    course = new Course();
    course.setCourseName( "Course ".concat(Integer.toString(i)));
    
    aList.add(course);
    System.out.println(course.getCourseName());
    
    }
    
    Course[] courses = (Course[]) aList.toArray(new Course[0]);
    
    Thanks

  - GridBag Layout queriesIt might appear long, but I think the answers will be of
    just a few words describing the correct command/syntax.
    
    After the Jbutton part has run successfully, the following
    difficulties are coming in the next step.
    
    - Individual buttons are not coming as same width. Whichever
    button has more text or wider letters is coming wider, and
    others are coming less wider.
    
    - though left edge of a column of button is duly aligned,
    the right edge is becoming zigzag due to the above.
    
    - width of the largest button in a column is deciding the
    width of the the entire column.
    
    how to force all button to be of same width? If all buttons
    in a column are of same width, the above are automatically
    solved.
    
    I am also finding that the three characters I have to
    display are appearing in the centre, and there is huge space
    left at the left and right of my text in the button.
    
    Because of this, I have to unncessary keep my window wide so
    that characters remain visible, otherwise several characters
    are not becoming visible.
    
    When I put setmargin I got this compile error.
    setMargin(java.awt.Insets) in javax.swing.AbstractButton
    cannot be applied to (int,int,int,int)
    button[gridY1][gridX1].setMargin(0,0,0,0);
    
    The best method would have been if we could have just given
    a single width for all buttons, and it would have compressed
    whatever text within that width.
    
    - Even after giving gridwidth as 2 or 3, though the button
    is reserving the width of those many columns, its width is
    still that of a single button. the area next to it is coming
    blank.
    
    how to make it wider to fill the columns it is covering.
    
    - Even after giving gridheight as 2, though the button is
    reserving the height of those many rows, its height is still
    of a single button. the area below it is coming blank.
    
    how to make it taller to fill the rows it is covering.
    
    ipadx or ipadx are not working. while trying to use
    gridBagL.setConstraints(button, gridBagC);
    it is giving error
    setConstraints(java.awt.Component,java.awt.GridBagConstraints)
    in java.awt.GridBagLayout cannot be applied to
    (javax.swing.JButton[][],java.awt.GridBagConstraints)
    
    what is the default height and width of a button?
    
    in place of using an icon in setrolloverenabled(), can we
    have some way to make it display whatever text is there in
    the button, in a larger font size?
    
    to set the horizontal alignment, if I am giving
    button[gridY1][gridX1].setHorizontalAlignment(0);
    
    it is still appearing at the centre. what are the options
    for (int) are not shown in the tutorial.
    
    Thanks.

  - SendMailServlet example & server setup ?I tried this example :
    
    // import the JavaMail packages
    import javax.mail.*;
    import javax.mail.internet.*;
    
    // import the servlet packages
    import javax.servlet.*;
    import javax.servlet.http.*;
    
    // import misc classes that we need
    import java.util.*;
    import java.io.*;
    
    public class SendMailServlet extends HttpServlet {
    String smtpServer;
    
    public void init(ServletConfig config) throws ServletException
    {
    super.init(config);
    
    // get the SMTP server from the servlet properties
    smtpServer = config.getInitParameter("smtpServer");
    }
    
    public void doPost(HttpServletRequest req, HttpServletResponse res)
    throws ServletException, IOException
    {
    // get the message parameters from the HTML page
    String from = req.getParameter("from");
    String to = req.getParameter("to");
    String subject = req.getParameter("subject");
    String text = req.getParameter("text");
    
    PrintWriter out = res.getWriter();
    res.setContentType("text/html");
    
    try {
    // set the SMTP host property value
    Properties properties = System.getProperties();
    properties.put("smtp.mail.yahoo.com", smtpServer);
    
    // create a JavaMail session
    Session session = Session.getInstance(properties, null);
    
    // create a new MIME message
    MimeMessage message = new MimeMessage(session);
    
    // set the from address
    Address fromAddress = new InternetAddress(from);
    message.setFrom(fromAddress);
    
    // set the to address
    if (to != null) {
    Address[] toAddress = InternetAddress.parse(to);
    message.setRecipients(Message.RecipientType.TO, toAddress);
    }
    else
    throw new MessagingException("No \"To\" address specified");
    
    // set the subject
    message.setSubject(subject);
    
    // set the message body
    message.setText(text);
    
    // send the message
    Transport.send(message);
    
    out.println("Message sent successfully.");
    }
    catch (AddressException e) {

  - _scripting engines for java applications_Hi All,
    
    I've written java app with classes that strickly corresponds to user's
    business domain. Now I want to add scripting feature to my program to
    enable user to create own scenarios of processing objects of those
    business classes. Where to start? Is there any scripting languages
    implemented in java?

  - javax.mail truncated urlHi!
    
    I use javax.mail to send http mails that include urls. On some mail
    clients, including Lotus iNotes, urls contained in the mail are
    truncated. For example:
    
    http://www.crappysite.com/index.html?param1=foo¶m2=bar
    
    becomes
    
    http://www.crappysite.com/index.html?param1
    
    Encoding in the email is set to "quoted-printable". I tried to set it
    to "base64" but it didn't resolve the problem.
    
    Thanks!

  - A Pixel Matching Problemthis problem is like a miniature OCR problem.
    
    Let's say you have some images that contain text, or screen snapshots
    obtained by the Robot class. How can you extract the text from them?
    
    You have the advantage that you probably have access to the fonts used
    to create the text.
    
    How might you go about creating an OCR for images? I was thinking of
    writing this up as a student project.
    
    The advantage you have over true OCR is all matches will be exact.
    
    The complications are a variety of colours for foreground/background,
    antialiasing and painting over muticoloured backgrounds. For JPGs you
    may not have the fonts used. The edges of the text may be tweaked in
    various ways, e.g. 3D, blurred, warped.
    
    I thought you might proceed like this:
    
    1. find rectangular regions containing only two colours.
    
    2. draw an e in 10 font sizes for each font as your search templates.
    
    3. look for a hole the right shape. When you find one, check all the
    e's you have with that size/shape hole to see if you have a match on
    the entire letter, check the whole rectangle.
    
    4. if you have a match, calculate the baseline and starting point. now
    draw a template ea in that same font and compare. If it fails try eb
    etc. Work your way both left and right pulling that line.
    
    You might construct a hashMap indexed by a digest of the glyph so you
    can more rapidly check for matches. Your digest algorithm might trim
    the glyph top/bottom/left/right so you don't need the stringWidth
    information by actually drawing the character pair.
    
    5. You carve the rectangle out of the bigger one, and break the
    remaining into rectangles.
    
    6. repeat until there are no more rectangles.
    
    7. export the text each labelled with x.y where it was found.
    
    8. In another program allow the user to highlight text, e.g. a column
    or box to determine the linear order of the text desired.
    
    Potential uses for such software include:
    
    1. capturing filenames, error messages, crash locations that were
    displayed in a non-cut/pasteable way.
    
    2. by people trying to defeat my email munger. See
    http://mindprod.com/applets/masker.html
    
    3. by blind people extracting textual information from images.
    
    4. To allow you to copy from any Swing Component.
    
    5. to extract information from a screen snapshot without having to
    retype it.

  - record numbersMaybe my question is stupid and wrong but I hope that you will understand.
    So, image that you need to create web application which will used by many
    peoples in one LAN. They processing some documents and every person has the
    particular number of documents in particular order (1. person has documents
    from 1 to 100, second from 101 to 200 etc), which process with the
    particular number (first document -> number 1 in a database). If they all
    work in a same time, what is the easiest and the most safety way to manage
    that? Adding number manually is the logical solution but if 2 person put the
    same number, can they freeze the database or databases are imune on that ?

  - awt default toolkitThe following will not show the image nor will it throw any exceptions. Not
    throwing exceptions doesn't surprise me because the documentation show that
    it won't. That is a little surprising in itself. I am not using Swing
    components.
    
    public void paint(Graphics g){
    
    String fileName = "dir/a.gif";
    Toolkit toolkit = Toolkit.getDefaultToolkit();
    Image img = toolkit.getImage(fileName);
    
    // an awt panel's Graphics context doesnot show the image
    g.drawImage(img, 0,0, null);
    
    //this works fine
    g.drawString("aString",50,50);
    
    }

  - HTTP creepIf you look at the packet headers going back and forth to your HTTP
    server, you will discover a HECK of a lot of blather that really is
    not doing much.
    
    It is made worse by it all being human readable without abbreviations.
    
    Add this overhead up on all packet headers being transferred each day
    and you see a stupendous waste of bandwidth.
    
    HTTP should be put on a diet, with rigid defaults, bitfield headers,
    and compressed messages.
    
    The original protocol was designed for maximum flexibility. Now we
    have some experience, we can tighten it up.
    
    It matters now that you have tiny handhelds trying to surf the net
    over limited bandwidth.

  - Going to NMU jikes (C++ ABI update)
    I'm notice on <URL:http://people.debian.org/~mfurr/gxx/rebuild.html>
    that jikes need a rebuild due to the new C++ ABI. I asked on
    #debian-java if anyone is working on that, but got no reply. It is a
    build-dependency on 119 packages, so it is probably a good idea to do
    it quickly. I plan to do the NMU myself shortly, so this is just an
    warning email.
    
    I only change debian/changelog, adding this entry:
    
    jikes (1:1.22-2.1) unstable; urgency=low
    
    * Non-maintainer upload to get a rebuild with the new C++ ABI.

  - socket & JVMThis is a multi-part message in MIME format.
    
    Hi i'm trying to create a some sort of JAVA print server:
    I've a machine that accept (throught a socket) some spool file........
    Here's the JAVA code:
    
    ServerSocket TServer;
    
    int i = 0;
    
    try{
    
    TServer = new ServerSocket(TPort);
    
    while( true ){
    
    //frame.TModel.addElement("+++ WAITING REQUEST " + i );
    
    Lpd_request request = new Lpd_request(TServer.accept(),frame,PQ,NumQueue);
    
    request.start();
    
    i = i + 1;
    
    }
    
    }
    
    the problem is: every request launch another JVM for handle the print and create a pdf of the the spool data: for some reason if i create a batch that launch 5 spool file one after the other, the print server launch 5 thread, but some thread terminate not correctly.
    
    In particular the exit code are 1-0-1-0-0 so the first fail, the second is executed and so on.....
    
    Can I put a delay between thread execution for solve the problem???
    
    Any suggestion????

  - Java Printing API and Tobit FaxWareThis example for the Java Printing API
    
    http://java.sun.com/products/java-media/2D/forDevelopers/sdk12print.html#printable
    
    creates different output in Suns JRE 1.4 and 1.5 (tested with Windows
    2000). This can be easily checked using the 'print to file' option.
    
    The different behaviour of the new 1.5 JRE is causing problems with the
    Tobit FaxWare printer driver.
    
    Tobit FaxWare detects special command strings in the document, which
    start with @@, followed by a command name and optionally a space
    character ($20, #32) and a character, finally @@ again. For example, the
    receiver fax number is encoded as @@NUMMER +4996421@@. If a document is
    printed on the FaxWare printer driver using JRE 1.4, the document will
    be sent as a Fax to this number.
    
    In JRE 1.5 however, the printer output contains the character $a0 (#160)
    instead of space, this is causing an error message in Tobit FaxWare.
    
    I would like to find the reason for this change but could not find
    information in the JRE 1.5 releasenotes
    (http://java.sun.com/j2se/1.5.0/compatibility.html#incompatibilities),
    is there another place where i could find informations about the
    background of this change?
    
    Many thanks in advance,
    Michael

  - java script problems XP dpreview and other sitesMainly on the popular digital photo site dpreview.com but
    unfortunately not restricted to this site I sooner or later run into
    the problem that the site navigation and posting does not work any
    more: Normally a list of available sub items is displayed on the left
    side, when positioning the cursor on any a specific pull down pops up.
    But every other week or so the site is displayed with an empty
    background where the menu normaly is and therefore no further
    navigation ist possible. I Opera I get the menus but when I click the
    javascript enabled send button for posts nothing happens too.
    
    I am running Windos XP Home with all current updates with Norton
    Internet Security 2002 and Norton System Works 2002. Even after a
    clean reinstall of all apps with all updates I don't get a stable
    system. My only rescue so far is to load a system partion image of a
    good status some weeks ago. But as I said, this does not last for
    long.
    
    I tried reinstalling Windows Script 5.6, but it did not help.

  - jdbc commit issueHi,
    
    I'm facing some problems with the JDBC connection commit.
    I'm using an Oracle8i client and server.
    The jdbc library is classes12.jar
    
    My application uses eclipse3.1 as an IDE and the jdk version is
    jdk1.5.0_01
    
    The flow of logic is such that I acquire 2 to 3 connections to my
    database repository. On each of these connections some update/insert
    statements
    are executed (through jdbc PrepareStatement->executeUpdate())
    After the update statements I issue a connection.commit() on each of
    the connections where update statements are fired.
    
    I have noticed sometimes that although connection.commit has been
    issued, my DB does not have any data.
    
    If anyone has any clue to this please let me know.
    
    Thanks for your time.

java-programmer, Using wildcard character in web.xml in Tomcat 5 I am trying to achieve the following:

<url-pattern>/a*</urlpattern> then go into servlet A. This would
include /a, /aa, /abc/123 etc.

I notice that servlet 2.4 doesn't treat * as a wildcard character in
this case. Therefore, servlet A would only be called if the URL is
exactly /a*.

I need to create this pattern for all characters and numbers except
when the path starts with '/_'. Therefore, I can not use a '/*'
notation. Can anyone suggest a workaround to this issue?

Thanks,
TC

    p.s. just to be clear, I want to understand the state of ALL sockets,
    not just the ones opened by Java. for instance, "netstat -a" on a
    windows platform provides the status of all TCP and UDP sockets.

  - actionPerformed programmaticallyHi
    
    Is it good way to programmatically call actionPerformed?
    NewAction action = new NewAction();
    action.actionPerformed(null); //maybe instead null should be something
    else, but what?
    
    Best Regards

  - 360degree rotation in Java2DI have a bit of a problem rotating Shapes using the Graphics2D function
    rotate(theta).
    
    My high-school trig lessons indeed tell me that sine and cosine functions go
    between -90 degrees and +90 degrees (or 0 and 180, if you like), and I can
    see why this means that when I call the rotate(...) function, it will not
    rotate the object all the way round the whole 360 degrees.
    
    Currently, I have a duplicate Shape object which is flipped so that for one
    half of the rotation the original shape is drawn, and for the second half,
    the other...
    
    There must be a better way!
    
    Any ideas?
    
    Cheers :o)

  - CLASSPATH?WinXP Pro, JRE 1.4.2_03
    
    I've just discovered that according to my Environment Variables section of
    the System icon (Control Panel), I don't have a CLASSPATH variable. I used
    SET from a command prompt to confirm that this is the case. No such
    variable. So how come I can run basic (UI) Java programs OK? Shouldn't
    CLASSPATH be pointing to the jar file containing these basic classes I'm
    using? The problem is, JMF installation instructions seem to say I should
    add the path to the jar file to CLASSPATH, but how can I if I have no such
    variable? {:v)
    
    Am I missing something?

  - reading values from JTableI am looking for a working example of a JTable that is constructed
    with initial values in the cells, allows the user to change those values,
    and reads the values out.
    
    I've got three books on Swing, none of them show a write/read table.
    
    I have no problem creating tables with nothing in some cells, and
    reading the values out that the user entered.
    
    Here is how I construct the tables:
    
    DefaultTableModel model01= new DefaultTableModel(rowData,colNames);
    JTable table01= new JTable(model01);
    
    Any help greatly appreciated.

  - Basic Struts loggingI'm learning Struts and I've got a simple example app running. I wanted
    to get logging working, so in the perform() method of my Action I put
    the code:
    
    ActionServlet as = getServlet();
    as.log("hello world");
    
    This compiled with no errors and ran without any problem; but the string
    was not written to either of the log files catalina.out or
    localhost_log.2004-09-21.txt (this is on Tomcat).
    
    Any hints or clues about how to get simple logging working? I looked at
    log4j and commons-logging but I want to start simpler.

  - Tomcat4: Default Page Encoding UTF8Hi,
    
    I am using Tomcat 4.1.27 running servlets which worked
    perfectly under Tomcat 3. The problem is: (unfortunately)
    the special characters (like german umlaute) are not
    html encoded. Under tomcat 3 this was no problem, but with
    the new tomcat the page-encoding is wrong. When I manually
    change the page encoding in the browser to utf-8 everything
    is OK. I could now go through all servlets and change the
    content-type to charset utf-8, but I try to avoid this.
    (as there where not written by me).
    
    Is there any possiblilty the change the default page encoding
    to utf-8? (like in the server.xml or so)
    
    Thank you for any help!!!

  - Together J 5.5Hi,
    
    once there was a "community version" of TogetherJ. I have a 5.5 on CD
    from a Together Presentation long ago but I am missing the community
    "licence.tg". It was free (long time ago) but no longer available now.
    
    Anybody out there with one of theses files?
    
    Thx,
    
    Christian
