  - intersection model with threads problemX-No-Archive
    Hello,
    
    I am trying to learn java threads, and to attempt an exercise from my
    textbook, hwever I am not sure if any of my proposed solutions are in
    the right vein...
    
    The problem is to model an intersection with trafficlights and 2
    sensors at each trafficlight, one for arriving and entering, and one
    for exiting..., and cars as threads.
    
    the time the car stays in for, the length of time it takes the lights
    to switch colors, and the number of cars must all be definable and easy
    to change..
    
    I was consiering having each car as a thread, and sensors and
    trafficlights as a monitors, when a sensor detects a car arriving, it
    notifies the trafficlight to change, and trafficlight will block or
    allow the car thread to run, ie enter or leave...
    
    I'm not sure if I am even on the right track, and can not find any
    example solutions to this problem, so if anyone has any idea I would be
    very gratefull
    
    Thanks,
    Jason

  - 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!

  - Programming with JCo (SAP)Hi,
    
    I hope there is someone out there with programming experiences in SAP
    over Jco.
    
    Unfortunately I have no SAP System here to test my code with.
    In the documentation is written:
    
    ------
    JCO.Repository mRepository;
    
    mRepository = new JCO.Repository("ARAsoft", mConnection);
    
    We invoke the constructor for JCO.Repository with two parameters; the
    first one is an arbitrary name, the second one either a connection pool
    name or a JCO.Client object. In other words: Both connection pooling and
    direct connections are supported. In (web) server applications, we
    should always use a connection pool for the repository. The userid used
    for the repository has to have sufficient authorizations in SAP for the
    metadata access to be possible. Please read the Javadoc for class
    JCO.Repository to find out which specific authorizations are required.
    You can use one special userid for the repository access and one or more
    "normal" userids for the actual application.
    ------
    
    I have the following code I was able to test on a foreign system:
    
    public JCO.Function getFunction(String repositoryName, String
    functionName,
    JCO.Client connection) {
    
    IRepository repository =
    JCO.createRepository (repositoryName, connection);
    
    IFunctionTemplate ft = repository.getFunctionTemplate (functionName);
    
    return ft.getFunction ();
    }
    
    To create the Repository I pass an object of type JCO.Client. I have got
    this object from a pool before.
    
    When I understand the documentation corretly I can also pass the pool to
    create a Repository. Then there wouldn't be no need to handle with
    JCO.Client objects.
    But I can not test this and thus I want ask if someone can confirm that
    this works.
    
    And another question: Since I don't need any Client objects then, I can
    not release them to the pool. Is that ok and happens implicitely, or do
    I have to do something else?

  - jdk 1.5 on linuxHi.
    
    Anybody tried jdk 1.5 on linux ?
    
    I downloaded it, but I can't use any of new features.
    Example : Generics
    
    import java.util.*;
    class test {
    List<String> list = new ArrayList<String>();
    }
    
    this class compile fine on jdk 1.5 on Windows, but make on error on
    linux :
    
    > ./java -version
    java version "1.5.0-beta"
    Java(TM) 2 Runtime Environment, Standard Edition (build
    1.5.0-beta-b32c)
    Java HotSpot(TM) Client VM (build 1.5.0-beta-b32c, mixed mode)
    
    > ./javac test.java
    test.java:4: <identifier> expected
    List<String> list = new ArrayList<String>();
    ^
    1 error
    
    on windows, java -version returns
    C:\Documents and Settings\Mike>java -version
    java version "1.5.0-beta2"
    Java(TM) 2 Runtime Environment, Standard Edition (build
    1.5.0-beta2-b51)
    Java HotSpot(TM) Client VM (build 1.5.0-beta2-b51, mixed mode,
    sharing)
    
    I downloaded the 2 version (windows & linux) together.
    Sun says that linux version is also a beta2 version but that's not
    what "java -version" report.
    
    So, anybody having the same problem or an idea on what happened ?
    
    Thansk in advance.

  - 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

  - Font Faces and Styles Not SetI'd like to see if anyone can offer an explanation for some font
    issues before I report the issues as bugs to Sun and Apple. Please let
    me know if you can explain the following as correct behavior.
    
    It appears to me that a lot of fonts simply don't work under Java 1.4.
    The simple application below should show fonts with a normal face,
    bold, italic and underline. Underline seems to work on all systems,
    but on both Windows and OS/X, bold and italic fail on many fonts. The
    same fonts seem to have bold and italic faces in non-Java
    applications, so it appears to be a problem with the JVM. For example,
    STENCIL on the Mac and Century on Windows both have distinct bold and
    italic faces in Word, but not in Java.
    
    On OS/X, many fonts do not display the proper face; they seem to
    default to serif or sans serif. Most of the Lucida fonts show this
    problem.

  - Read data from CSV FileHi all. I am currently trying to develop a program that will read data
    from a CSV file which includes computer names that have been exported
    from Active Directory. I want my java program to read in the CSV file
    and get the data and place it into the JList.
    
    Is this possible.
    
    Any help in this matter would be highly appreciated.
    
    Thank you

  - ImageIO.read(url)Hi,
    
    I have an applet with this operation, from the Eclipse it is running without
    problem.
    
    When I upload to the web, I receive an "access denied".
    
    Then I find that i need a signed applet. I signed the applet in a jar file,
    and uploaded again.
    
    The communication between java & javascript is working, but I continue
    receiving the "access denied" error.
    
    How can I set the security permissions to allow the applet to load the image
    from an URL that is in another server ?
    
    I need to use another object to read the image ?
    
    Thanks to all.

  - Pipelining COM portsIs it possible to create a pipeline to virtual COM port (MS Windows)?
    
    I connect a mobile phone to PC over Bluetooth and
    [CommPortIdentifier.getPortIdentifiers();] does not enumerate any port,
    neither COM1 nor virtual port for mobile phone.
    
    If I use [new FileOutputStream("COM10");] then I can send data to
    mobile phone but I can't read the response.
    
    Basically, I need to open a pipeline to file. Where can I find more
    information on this topic?

  - 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...

  - 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).

    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 :)

  - nio sockets + SetTcpNoDelay Exception...Hi,
    
    I use Nio sockets in a production projet for a while, without a single
    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

  - Aspect oriented Everything?Hello,
    
    Aspect oriented Software development seems to be expanding in the
    popular vision of developers, with more and more IDE 'add-ons' and
    even more specialized tools,Jboss etc.
    I've seen more and more languages integrate AOP,AspectJ (Java),
    AspectR(Ruby)etc.Aspect oriented does seem to be the place to go from
    a developer standpoint.What I want to know is,if anybody on a
    commercial scale is using AOSD to develop commercial products? Is an
    Open Source development ever going to gain the trust of industry? It
    may be ok for personal projects and other Open Source material but
    will your bank ever accept it? Is it the fact that AOP is new and, for
    most,confusing or is it the fact that AOP has developed in the
    environment it has.i.e Open Source,that may dissuade commercial
    development shops from accepting AOP.
    
    What are the main features that may lead to AOSD adoption? Is AOP the
    next step on from OOP? Is it another chance for some of the lesser
    utilised languages to step up to Java and C++? Your opinions on the
    subject would be appreciated? Design features are one thing but
    widespread adoption is another, or is it?
    
    Anything you care to add on the subject would be appreciated on this
    short questionnaire.

    Thank you for your participation.

  - finding java difficultI know Visual Basic and few other commands in Oracle but I am having
    trouble learning high level Java. Should I just read over and worry
    about it later? I understand Arrays and If statements but found for
    example, " overiding and hiding methods" difficult. It states a
    superclass overides a superclass. I am confused!
    
    here is "overiding and hiding methods" from the sun.com site;
    
    An instance method in a subclass with the same signature and return
    type as an instance method in the superclass overrides the superclass's
    method. (Remember that a method's signature is its name and the number
    and the type of its arguments.) You can also override a method with the
    same signature that returns a subclass of the object returned by the
    original method. This facility (introduced in 5.0) is called covariant
    return type and you can see an example in Annotations (in the Learning
    the Java Language trail).

  - BigDecimal Builder and immutability...Our application uses BigDecimal, and BigDecimal is immutable. Immutability
    is certainly a good thing, but it also means that there are a lot more
    memory allocations (and collections). That's ok, we are all happy that
    Strings are immutable, but Java also gives us StringBuilder and
    StringBuffer. Is there anything similar for BigDecimal?
    
    BigDecimal operations are the hotspots in our application and the GC is also
    very busy collecting all the objects. Unfortunately double are not good
    enough for us. Ideally we would like something like C# Decimal: a 128bit
    decimal number (not floating point, but decimal), I have not actually used
    this, but from what I have heard it is what we would need..
    
    I googled the web for a fixed precision decimal class for Java, for an
    immutable version of BigDecimal, etc... I could not find anything. Do you
    know of anything that could help us?
    
    Thanks,

  - Beautify HTMLHi,
    
    I need to beautify HTML files from within my web application. These
    files come from an online editor that writes its output on a single line.
    
    JTidy might be a solution, but there is no documentation and so it's
    very hard to test it on the fly. After all, I don't need a complete
    parser: a simple formatter/beautifier would be great. Does anyone know
    of such a class? Arachnophilia does it, but it's not an API.
    
    Thanks

  - SetProperty per oggetti Complessi Salve a tutti,
    
    sto sviluppando un'applicazione web piuttosto complessa in java che utilizza il framework Bluprint della Sun.
    
    In particolare, la mia problematica è legata alla gestione degli oggetti di business nell'interfaccia con l'utilizzo, nelle jsp, dei metodi setProperty e getProperty java.
    
    Gli oggetti che utilizzo sono i seguenti:
    
    ‘public class Anagrafica implements java.io.Serializable {
    
    ...
    
    private Vector indirizzi;
    
    }
    
    ...
    
    public class Indirizzo implements java.io.Serializable {
    
    protected String tipo;
    
    protected String particella;
    
    protected String address;
    
    protected String houseNumber;
    
    protected String zipCode;
    
    ...
    
    }
    
    Ciò che voglio realizzare è la visualizzazione nella jsp dell'interfaccia di tanti ‘frame' quanti sono gli oggetti Indirizzo contenuti nel Vector di Anagrafica. Scrivendo, però, ciò che segue:
    
    <jsp:useBean id="..." class="..." scope="session">
    
    <jsp:setProperty name="indirizzo" property="*"/>,
    
    il metodo setProperty non setta le proprietà complesse dell' oggetto vector indirizzo.
    
    Spero di esser stata chiara.
    
    Attendo un vostro suggerimento...

    The example had no code. Only the question which I posted. The whole point

    As I said in my reply to Nigel, questions about programming (similar to
    programs about science and math) are very clear-cut. If every word of an
    answer isn't true, the answer is incorrect. At least that's how it is in my
    experience.

    No surprise. I just wanted to see if this was indeed one of those ambiguous
    questions. Apparently it is. If I saw this question on an actual test, I
    think I'd still answer it as I have here, because I haven't really heard a
    convincing explanation why not to. It seems that every response either
    explicitly or implicitly has something to do with "interpreting the answer"
    to mean something slightly different from what it says. I'm still going to
    have to stand by my original response to the question: you cannot
    synchronize access to a variable. Therefore a thread will never need an
    object's monitor in order to access a member variable of that object.
    Therefore, a thread will never be waiting on said monitor.

  - Looking for a gui class to pop up to let user choose directory and filenameHi,
    
    When I output something to a file, I hope something pop up that let the
    user to select the directory and input the file name. I don't know how
    to do it. I can hard-code the file name in my program and use
    PrintWriter class to do it, like:
    
    PrintWriter outputStream = new PrintWriter(new FileOutputStream("out.txt"));
    
    outputStream.println("hello world");
    outputStream.println("how are you?);

  - Manifest.mf Class-path troubleHi group!
    
    I'm deploying an application with this structure
    
    app
    app/app.bat
    app/lib/app.jar
    app/lib/another.jar
    app/plugins/other/
    
    where the (windows) batch file starts the application like so:
    java -jar lib\app.jar
    
    and the Manifest.mf with that jar puts another jar on the classpath
    like so:
    Class-Path: another.jar
    
    Now I also want to put any plugin classes that users put into
    app/plugins/other/ onto the classpath, roughly like so:
    Class-Path: another.jar "../plugins/other/*"
    
    So far I've tried a few variations, but the development cycle is quite
    tedious and it ain't workin yet.
    I'm wondering:
    
    * use quotes ?
    * forward slashes ok on windows or do I need separate versions for Win
    vs Unix ?
    * end the directory with / (or resp. \) or nothing (../plugins/other) ?
    * end the directory with "/*" or possibly "/*.class" ?
    
    Alternatively I could use the java -classpath arg in the batch file,
    but I've tried that and it's not working either, so I'm getting the
    impression that using the Class-path: line in the manifest somehow
    disables the -classpath arg of the java command. Is that so?

    The application counts rows number and columns number and import data
    into a bidimensional array of double type.
    I compile my code and i have this error
    
    Exception in thread "main" java.lang.NumberFormatException: For input

    How can i do?
    Please help me with code, i'm a new java user...
    Here is my code
    
    import java.util.*;
    import java.io.*;
    public class AddDb {
    private static String fileName="Dato.txt";
    private static int Ncolumns=0;
    private static int Nrows=0;
    
    public int ColumnsNumber(BufferedReader br)throws IOException {
    
    String line = br.readLine(); //legge una linea di testo terminata
    da /n o /r e la restituisce come stringa
    StringTokenizer st = new StringTokenizer(line);
    Ncolumns=st.countTokens();
    
    return Ncolumns;
    }
    
    public int RowsNumber(BufferedReader br)throws IOException {
    
    String line = br.readLine();
    while (line != null) {
    Nrows++;
    line = br.readLine();
    }
    return Nrows;
    }
    
    public double[][]ReadArray(int Nrows,int Ncolumns,BufferedReader
    br)throws IOException
    {
    double[][]x=new double[Nrows][Ncolumns];
    for(int i=0; i<Nrows; i++)
    {
    StringTokenizer tok=new StringTokenizer(br.readLine(),"");/
    for(int j=0; j<Ncolumns; j++)
    {
    
    x[i][j]=Double.parseDouble(tok.nextToken().trim()) }
    
    }
    
    for(int i=0; i<Nrows; i++)
    {
    for(int j=0; j<Ncolumns; j++)
    {
    System.out.println("L'array bidimensionale ?+x[i][j]);
    }
    }
    return x;
    }
    
    public static void main(String[] args)throws IOException {
    FileReader file = new FileReader(fileName); BufferedReader br =
    new BufferedReader(file);
    AddDb db=new AddDb();
    br.mark(99999);
    db.ColumnsNumber(br);
    System.out.println("Il numero di colonne e' :"+Ncolumns);
    br.reset();
    br.mark(99999);
    db.RowsNumber(br);

    corso.....");
    try
    {
    System.out.println(db.ReadArray(Nrows,Ncolumns,br));
    }
    catch(IOException e){
    System.out.println(e.getMessage());
    }
    br.close();
    
    }
    }

  - Webstart ignoring minor J2SE version numbersI'm trying to build my first WeStart aware application. I've JARed it
    and assembled my HTML and JNLP files, but am having a lot of trouble
    with the <j2se> tag.
    
    I would like my users to use Java 1.4.2 or later. (I have 1.4.2-b28
    myself). However, when I use the tag <j2se version="1.4.2+"/>, web
    start replys that a JVM of this version is not installed, and that it
    cannot find an appropriate JVM to download either. Changing that to
    "1.4.2" - the example given in the documentation - creates the same
    error. However, "1.4+" download and runs the application.
    
    My app relys on some bug fixes from versions post 1.4.0, and I'd like
    my users upgrade to the appropriate JVM. Is there a way to get this
    done?

  - Fast image scalingHi all,
    I'm writing a program which involves drawing several copies of the same
    image inside of a JPanel. I have a listener on the mouse wheel to
    "zoom in/out", so that every image scales up or down in size at the
    same time. I'm having many problems getting this to run smoothly.
    
    I first tried to scale the image just once (since it is drawn many
    times) by calling getScaledInstance, saving the resulting image, and
    then drawing that lots of times. However, even though I am using
    Image.SCALE_FAST, it sometimes takes a while to update the image when
    scaling to larger sizes. (Note, the image is 440x250, and I'm never
    scaling it larger than double its size.)
    
    The second thing I tried was to use an AffineTransform to scale the
    graphics object just prior to drawing the image. This gave slightly
    better results during the actual scaling, but it caused random hitches
    (half-second pauses where all movement in the program completely
    stops), even when I wasn't actively changing the scale. I finally
    deduced that the scaling causes some garbage to be created, and the
    hitches happened when the garbage collector ran. (I also tried without
    the AffineTransform, and just using the width/height arguments in
    drawImage to scale on-the-fly, but the results were the same.) Please
    also note that when I don't scale the image at all, the drawing is
    perfectly smooth and fast.
    
    What I'm doing doesn't seem to be nearly as intensive as what most
    people are capable of doing, so clearly I'm doing something wrong. If
    anyone could point me in the right direction, I'd be most appreciative!
    Thanks!
