  - directory questionI have a file named "main.ini" in the directory of jar (self-executable
    package)
    When I run jar from its directory all ok
    When I run jar from another directory it cannot found "main.ini"
    
    I open "main.ini" with
    InputStream is = new FileInputStream("main.ini");
    but I understand I must open it with
    InputStream is = new FileInputStream(getDirectoryOfJavaProgram() +
    "main.ini");
    
    can you implement
    getDirectoryOfJavaProgram()???
    
    thanks!

  - Timouts for RMIHi all,
    i know there are several posts, and a google search found lots of hits on this topic.
    My Problem is: Nothing works...
    
    My intension is very simple:
    Use Rmi to transmit data from a client to a server.
    In principle it works fine. My Problem are the RMI-timeouts. They are too long.
    
    I have to take into account that some "unclever Guy" pulled the network plug.
    My Client still wants to send data to the Server (call a servermethod via rmi).
    I call the method and this thread is blocked. Fine. Network is still broken.
    
    Depending on the OS of the client (windows, linux) the Timeouts vary.
    In Windows its about 20 Sec => Exception. In Linux? Years? It looks like the method never returns
    with an error.
    
    Is there a way to set the timeout for calling a method.
    (The time after the methodcall returns an error when the server isn't reachable)
    
    I tried:
    a) Setting the RMISocketFactory creating my own clientsockets having the SoTimeout set... didnt work.
    b) setting the Systems sun.rmi.transport.connectionTimeout ... didnt work
    
    Hope you can help me.

  - Setting namespaces in DOMHi all,
    
    I'm trying to construct an XML (SOAP) document, with a number of namespaces.
    
    DOM provides Document.createElementNS(), which can be used to add the
    namespace in the particular element. However, I often get the case where
    the namespace definition is repeated in multiple sibling elements, while
    it would be a lot simpler (cleaner?) to define the namespace only once
    at a higher level.
    
    I tried using
    
    document.getRootElement().setAttribute("xmlns:xsd", XSD_NS);
    
    but, even though the document.toString() shows the correct xmlns:xsd
    attribute in the root node, it is still repeated in the lower level
    elements.
    
    Does anyone have any idea of how the DOM decides when to "roll-up" a
    namespace definition to a higher level? Or how to tell it to?
    
    I'm talking about the difference between:
    
    <rootnode>
    <childnode xsi:type="xsd:int" xmlns:xsi="http://w3c.blah"/>
    <childnode xsi:type="xsd:int" xmlns:xsi="http://w3c.blah"/>
    <childnode xsi:type="xsd:int" xmlns:xsi="http://w3c.blah"/>
    </rootnode>
    
    and
    
    <rootnode xmlns:xsi="http://w3c.blah">
    <childnode xsi:type="xsd:int"/>
    <childnode xsi:type="xsd:int"/>
    <childnode xsi:type="xsd:int"/>
    </rootnode>
    
    Many thanks.

  - How to get files files which were last usedHi,
    
    is it possible to determine the files which were last used from
    different applications (e.g. "readme.txt was used in the last 2 hours")
    on MAC with Java by default System calls?
    
    Or is this only possible by writing a sort of "trigger" application?
    
    Thanks,

  - another design question, abstract static methods...so here is another general question about java...
    
    why can't you declare an abstract static method.
    
    i can envision the case (indeed i have experienced the case) where one
    would want an abstracct superclass, with an abstract method such that all
    subclasses that implement this method make that method static.
    
    basically, the abstract class declares an abstract method that should be
    static for all implementations (for example a factory method).
    
    this isn't allowed in java, and in the language specification, there is no
    reason given as to why. it is just simply stated in a single sentence
    that an abstract method cannot be static. (or it turns out even the
    implemented method).
    
    can anyone explain why this isn't allowed? (i.e. give an example that
    shows the flaws that can arise from such a situation).
    
    thanks much!

  - Question concerning jh_manifestHi Matthew,
    
    I have further researched this problem. To me it seems a (not too
    trivial) bug in jh_manifest. See
    http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=489214. Maybe better to
    discuss the topic there to keep this list clean...
    
    Cheers,

    Turing completeness is only one measure of power. And not a very
    good one for measuring different systems of templates. If you use
    templates for any sort of computational programming beyond some
    very simple things you are stretching the rubber band beyond its

  - ASP.NET vs J2EE - Scalability and SpeedRegarding this pieces of information:
    65% of the Fortune 500 companies
    80% of the top US healthcare companies
    75% of commercial banks worldwide
    90% of the top commercial banks in the US
    67% of the world's largest banks use IBM messaging servers
    15 of the top Wall Street brokerage firms
    7 of the 8 largest US telecommunications companies
    
    That's true. But what I can understand about that figure was -
    Those businesses started using Internet and Computer Networking
    technologies times ago. It happens before Microsoft started to get
    strong. I am working in a pharmaceutical company in US and we are using
    lots of IBM products. We are trying very hard to stop using them and
    turn our techology to Microsoft. Off course, personnally - I hate
    microsoft - I dont' feel fun when I use any one of micrsoft product.
    But in the business term - Microsoft products are qualified. Cheap to
    support and run - some tools are never over kill such as SQL server. We
    are using Oracle but I found only SQL server that just more than enough
    and a lot cheaper to run (cost of DBA and Programmer, etc).
    
    Webspere? Naaa .... we have been using Webspere when we started having
    our own Web site and Intranet sites. Then we changed to Coldfusion in
    the last 5 years. I found those suck! Cost too much money - when
    Microsoft IIS5 or 6 are free also .NET - so, why not!!!!
    
    Sure - a lot of Banks use J2EE - same reason! They rally want to stop
    using it but they cannot because everybody started with J2EE and know
    J2EE better than anything else!!!
    
    Sad but true!

  - Two column list with JOptionPaneYes, this is a homework question. My assignment is:
    Modify the mortgage program using a graphical user interface to allow the
    user to input the amount of a mortgage and then select from a menu of
    mortgage loans: 7 year at 5.35%, 15 year at 5.5 %, and 30 year at 5.75%.
    Use an array for the different loans. Display the mortgage payment amount.
    Then, list the loan balance and interest paid for each payment over the term
    of the loan. Allow the user to loop back and enter a new amount and make a
    new selection, or quit. Insert comments in the program to document the
    program.
    
    I have been able to complete all of it except the part about list the loan
    balance and interest paid. I used JOptionPane to do all the graphical user
    interface and the menu of mortgages (see code below), but can't seem to come
    up with a way to display the information in JOptionPane. If there is
    another way that will work please point me in the right direction.
    
    private static double option(double inputAmount)
    {
    // declares variables
    double amount = inputAmount;
    double monthlyPayment = 0.0;
    boolean done = false;
    
    // loop while not done
    while (!done)
    {
    // declare and set size of/initializes array
    double loanInfo[][] = new double [][] {{5.35, 5.5, 5.75},{7,15,30}};
    
    // creates an array to hold the options
    String smallList[] = {"7 year at 5.35%","15 year at 5.5%","30 year at
    5.75%"};
    String option = (String)JOptionPane.showInputDialog(null,"Which loan
    option?","Options",JOptionPane.QUESTION_MESSAGE,null,smallList,smallList[smallList.length-1]);
    
    for(int count = 0; count < smallList.length; count++)
    {
    // checks answers for match and sends info to calculate payment
    if(option == smallList[count])
    {
    // calls method to calculate the monthly payment
    monthlyPayment = calculationsPayment(amount, loanInfo[0][count],
    loanInfo[1][count]);
    done = true;
    }
    }
    }
    return monthlyPayment;
    }

  - Technique for loading user defined modulesDear all,
    
    I am writing a program to do data analysis. I want the user to be able to
    extend the functionality of the software by adding their own "analysis
    modules" but am unsure how to go about this. From the user perspective, I
    would like the application to look in a particular directory (or along some
    user defined search path) for modules (classes) with the appropriate
    behaviour and make these modules (classes) available through the program's
    user interface.
    
    It must be possible to complile these modules without access to the source
    code for the entire data analysis program.
    
    Can anyone give me some hints on which direction I should go in to handle
    this issue?
    
    Thanks in advance,
    Per

You have to learn to be specific. Otherwise you'll either get silly answers or
none at all. "Word ate my document" just won't do.

Yes, you could edit the config files yourself, or you could create a new
web project and copy the files into it (NOT using eclipse).

  - JNI , shared stubs, CFunction (not CFunc) ?Hi,
    
    I've been reading about JNI and shared stubs at
    
    http://java.sun.com/docs/books/jni/html/jniTOC.html
    
    However, when i try to use the class "CFunction" (see 9.4.3 @ url) , my
    compiler (IntelliJ) says it cannot find the class.
    I did find a jnistb10.zip , containing CFunc, CMalloc, CPtr, and the C
    code for "disp.dll". However, this zip contains "CFunc" instead of
    "CFunction" ! This is fine for wrapping a simple C calling convention
    function like "atol" (this example works with CFunc) , but i want to
    wrap some "stdcall" win api functions. With CFunc i get an access
    violation, probally due to the fact its not a C but a stdcall function.
    So i've been searching for the new and improved classes, namely
    CFunction , but unfortunally i cannot find it anywhere. Strange how it
    seems to be part of the JVM since 1.2 , but just doesnt seem to be there.
    
    Anyone who can help me ?
    
    Thanks,

  - JAI - Reduce memory requirements for TIF --> JPEG translationHi,
    
    I'm using the following code, copied off the internet, to translate a
    TIF file to JPEG format. It works, but runs out of memory on one of my
    machines. I can "solve" that by giving Java more memory at launch, but
    this is running in a context where I don't have easy access to those
    parameters, so I would prefer to reduce the memory requirements for the
    function. I'm still reading up on JAI and it's a lot to take in at one
    time; I'd appreciate any pointers to more memory-efficient ways to go
    about this. Thanks!

  - ploting 2D graph and able to change at run time..(JFrame)
    Hi everybody,
    
    Sorry for not clear question in my last post.. and more thanks
    for your reply..
    
    The exact requirements in graph are..
    
    1. The graph should have all feature of X & Y scale, grid, X
    and Y label and multicurve.
    
    2. The graph X & Y scale range should calculated at run time
    (max and min)from X and Y array and display.
    
    I hope these above requirements are understandable for little
    while... I am not new for java but i am new for graph application.
    
    So..can any one of you tell me where i get this kind of graph
    packages or APIs for free?

  - Detaching Applet to a Frame: the Frame is iconizedHi,
    
    thank you all for your replies, I've used the BorderLayout
    and GridBagLayout to get the exactly layout I wanted.
    
    I have another, probably simple question: now I'd like
    to be able to detach my applet from the browser on a
    button click, so I've created a big panel to keep all
    the components and a frame serving as external window:
    
    void detach() {
    but[1].setActionCommand("Attach");
    but[1].setLabel("Attach");
    frame.add(bigPanel);
    frame.pack();
    frame.setSize(Math.max(frame.getSize().width,
    (int) (1.2 * getSize().width)),
    Math.max(frame.getSize().height,
    (int) (1.2 * getSize().height)));
    frame.show();
    frame.toFront();
    }
    
    void attach() {
    but[1].setActionCommand("Detach");
    but[1].setLabel("Detach");
    add("Center", bigPanel);
    validate();
    frame.setVisible(false);
    }
    
    This seems to work quite well (I hope I don't leak memory)
    with one small problem: after I click the "Detach" button
    several times, the external frame always appears iconized
    (at least in the KDE window manager that I use).
    
    The frame.show() and frame.toFront() commands don't help.
    
    The applet + source code are at http://pref.dyndns.org/grid/grid2.html
    
    Any suggestions please?

    Recently I'm using the Sun NetBean IDE 5.5.1 in Windows, and I found
    it'll become very slowing when long time no operation then open it.
    In task manager if long time no use then use the NetBean, the memory will
    become low;
    then open NetBean it increase the memory and diffucult to use the editor.
    Fianlly it up to near 150M, then operation is smooth, would you tell me
    what happend and how to avoid the memory decreasing ?
    
    Regards. Ahan Hsieh

  - Mono, Java and the patentsThere's a new website for the so-called Mono-Project.
    http://www.mono-project.com
    
    <cite>
    "
    Mono is positioned to become the leading choice for development of Linux
    applications as well as cross platform applications.
    "
    
    Translation:
    "we consider Mono as the major Linux-development-platform"
    "don't take Java for crossplatform-development, take Mono".
    
    <cite>
    "
    However, the Java runtime systems commonly available on Linux
    lack the performance that customers demand, and Java applications
    do not conform to the Linux GUI look and feel.
    "
    
    Never heard of SWT or Swing-Synth-Look?
    And Java is slow and Mono is fast? What's about a detailed benchmark?
    Oh wait ... Mono is BETA and not optimized and whatever.
    So we have no benchmarks but we pretend that Java is slow and sucks.
    
    But more interesting is the following excipe from the Mono-FAQ:
    
    http://www.mono-project.com/about/licensing.html
    "
    The core of the .NET Framework, and what has been patented
    by Microsoft falls under the ECMA/ISO submission.
    Jim Miller at Microsoft has made a statement on the patents
    covering ISO/ECMA, (he is one of the inventors listed in the patent):
    https://mailserver.di.unipi.it/pipermail/dotnet-sscli/msg00218.html
    "
    
    Once upon the time an unimportant and unknown Microsoft-employee
    has made an unimportant statement on an unimportant mailing-list ...
    and that makes Mono a safe project?
    
    And Mono should be the major Linux-development-platform?
    Based on such a statement?
    Unbelievable.

  - BUG in jre that work fine in jview - mouseEventAnyone come up with an answer to this?
    I'm having the same problem, I've created
    a "skin" slider control in J++, when I use
    Microsoft it returns coordinates relative to
    the slider control, when I use Sun it's relative
    to the applet, the listener class and handler is
    within the slider control class.
    
    I've found LOTS of examples online that are setup
    just like my code, and they all, including Sun's
    documentation (as well as Microsoft's) say it should
    be relative to the control.
    
    Thanks,
    EdisonCPP
