  - An intranet questionAnybody know how to obtain the information of all the hosts that are in
    the same local network as mine? For example, on Windows, how can I get
    a list of computers' information in the same workgroup?
    
    Computers in the same intranet has the same IP address prefix (such as
    192.168.0.1 through 192.168.0.255). Especially I want to get the list
    of those hosts' IP addresses.
    
    Is any class in package java.net able to do this job? Hope I clearly
    express my problem. Thanks!

  - setting keys in xmlspyI would like to assign custom key combinations for xml functions. Some
    of the combinations are handled by the menu key, such as alt-w will
    open the windows menu. I would like to set that to file/save. I would
    also like to set alt-x to quit but it opens the XML menu.
    
    so is there any way to change this behaviour? Other development
    environments automatically handle these customizations.
    thanks for the help

  - Java3D and NVidia RIVA TNT graphics cardI'm using a Dell Dimension PC with Win98 and a NVidia RIVA TNT graphics
    card. After loading Java3D 1.3 and attempting to load
    HelloUniverse.html, I get:
    
    "No compatible device found, please switch to other display mode and
    try again."
    
    The bottom bar of the IE window displays:
    
    "exception:java.lang.NullPointerException: Canvas 3D: null
    GraphicConfiguration"
    
    I tried different combinations of 32 bit color vs. 16 bit color, and
    Java3D DirectX vs. Java3D OpenGL.
    
    Any clues?

  - Database and java.sql.SQLException QuestionsHello everyone!! I am back for some more much need advice and assistance! I
    am creating a database for the first time. I am changing some programs I
    recently wrote to work with this database that have to do with Salesmen. I
    am getting the below error when I compile CreateDatabase.java. In that I am
    creating the database SalesDatabase and then creating 5 tables (Users, SType,
    Salesman, Sales, Product). The first thing I do is create those tables and
    then insert informtion into the SType table and Product table. SType is the
    SalesType of a salesman, meaning Entry, Junior or Senior that also has the
    bonus in there as another field (.05, .10, .15) and then product has product
    1, 2, 3, 4, and 5 with the corresponding price of each. After I do this I
    need to read in a text file (SalesInformation.txt) and calculate the sales
    based on the information in the database. So here are my questions:
    
    (1) What is the below error telling me, have I not set the database up
    correctly?
    (2) Am I on the right track with what I have below, should I be reading the
    text file as I am or should I change it to be its own method (anything you
    tell me would be apprecaited!!)?
    (3) Also, other than it not compiling...lol...I am unsure of the salestype
    part with element 6 on line 124. I read in ENTRY, JUNIOR or SENIOR from the
    salesinformation.txt file so how do I relate that with retrieving the bonus
    number from the database?
    
    Ok, I think that is enough questions for now. If anyone needs any additional
    information as to what I am trying to do, just let me know and I would be
    happy to fill you in!! I appreciate any hints or tips you may be able to
    give and I look forward to getting this thing working :)!! Thanks everyone!

    But you should. Nobody cares if they suck or not. This is about you
    selling yourself to an employer.

    But why do *you* complain about *them*? If they can't get you a job,
    it's *your* job to do so! Manna doesn't fall from the sky.

    That tells me that you should have made more noise. Maybe you find it
    irritating. Maybe you despise that kind of people. But nobody cares.
    They got a job, and you didn't. It's about priorities.
    
    > Even now my interactions with them are non-complaining, merely sending
    > my tailored resume in response to their job ad, and waiting patiently
    
    These are claims you make, but I'd like to question how well these
    resumes are tailored, and how well they're presented. Since you don't
    have a graphical browser, maybe your word processors aren't too modern,
    either. (just assuming, maybe I'm wrong here)

    Sure, .doc isn't cool, but if it's what everybody wants, you should get
    used to it. It's your choice to stay out in the rain, but you're
    complaining about that, so start playing by *their* rules.
    
    It's a problem with several dependencies. If you need a PC with
    MS-Word, get one *before* tackling the job application problem. Good
    ones are on ebay for cheap.
    
    You pay $20 every month for a shell account. What does it do? Some
    file storage, a C compiler, ...? Great, I bet everybody in this ng and
    every single CS student has all that on their home computer, running
    Linux, BSD or whatever. And it even runs a graphical browser.
    
    For word processing you can get OpenOffice for free, if they don't
    accept resumes in TeX.
    
    If you need to, live without web access for a year, save the $20 a
    month, and go buy a decent machine then. It seems that sitting at your
    shell account, writing news articles here doesn't buy you anything, so
    save those $20.

  - What does this mean? (The type xxxx.yyyy cannot be resolved. It is indirectly referenced from required .class files)The class in question is being used just fine a few lines above where
    this error is being generated. The only difference is that the
    reference generating the error is on a static member function.
    Non-static references are working just fine. I am using Eclipse
    3.0.1. The static function is showing up in the package explorer, but
    does not show up in the editor quick complete window when I type the
    class name followed by the member operator. Only the non-static
    member functions show up. Any idea what is going on here? The rest
    of the project (very large, hundreds of source files!) seems to
    compile just fine.

  - How to display a "double" in all its precision???Hello,
    
    Here is a code fragment that is very simple... but I can't get it to
    work!
    
    public static void main(String[] args)
    {
    for (int i = 1; i <= 30 ; i++)
    {
    double x = Math.pow(2, i);
    x = 1 + 1 / x;
    System.out.printf("For i = %d: %.40f%n", i, x);
    System.out.println(
    Long.toBinaryString(Double.doubleToLongBits(x)) );
    System.out.println();
    }
    }
    
    All this code is supposed to do is print out the fractions 1+1/2,
    1+1/4, 1+1/8, etc. When one prints out the raw bits (see
    doubleToLongBits), the code is clearly working.
    
    But on the regular printf("For i...etc"), at i=17 and above, the
    numbers get frozen at 16 digits displayed after the decimal point (the
    precision). But it's not really the precision, because the bits ARE
    changing correctly. What gives???
    
    Help!

  - which VM ?Hi,
    I'm a teacher and I wrote some applets for my students. To be compatible
    with most browsers they could use I wrote these applets in Java 1.1.
    It works fine on IE of Windows 95, 98, 2000, but not on some versions of
    Windows XP which require the JVM download.
    Some of my students get a very slow modem and I can't ask them for
    downloading large amounts of MBytes.
    Since I only use the java 1.1 version, where I can find the most little JVM
    for this ?
    Is there a zip, or autoextractible version of it ?
    Thanks a lot.

java-programmer, Action selected state in JDK 1.5 Hello all!

Does anyone know of or have a solution of how to have automatic
updates for buttons and menu items created from Action's FOR JDK 1.5?
I know that automatic support for it was added in JDK (1.)6.0, however
the requirements for the software I'm developing is Java 5...

When calling new JMenuItem(Action) or JButton(Action), basically any
radio button or checkbox AbstractButton component, calling setEnabled
an the action turns the button AND menu items to gray. I would simply
like to achieve that for the selected state as well: Whenever the user
clicks on a toolbar button OR menu item, the selected state shall be
reflected in the other GUI component, too. As stated above, a solution
is inside the "too new" JDK6.

So, has anybody implemented a solution for this? Maybe some
AbstractAction subclass?

Any help on this appreciated! (directions etc.)

TIA
Karsten

  - j2ee request resource is not available hello1Hi all,
    I have found a solution to a problem that I would like to share.
    
    I am running WindowsXP and J2EE sdk 1.3.1.
    I was trying to run the Hello1 servlet example from the J2EE examples
    from sun. I found this error message: j2ee request resource is not
    available
    
    Then I solved this problem by opening the application in deploytool:
    Filling in the following fields:
    Hello1App: WebContext-> WAR File = Hello1WAR; ContextRoot = hello1
    GreetingServlet -> aliases = /greeting
    ResponseServlet -> aliases = /response
    
    This solved the problem and it was running fine.
    
    Hope it helps,

  - Can't locate JavaxHi,
    
    I am using DrJava, and I am writing a program that has the following
    statement:
    
    import javax.swing;
    
    It gives me this error when compiled:
    
    File: C:\Program Files\DrJava\CustomJFrame.java [line: 1]
    Error: package javax does not exist
    
    I did set my classpath variable to:
    
    c:\j2sdk1.4.2\lib\tools.jar;C:\j2sdk1.4.2_01\src\javax
    
    where C:\j2sdk1.4.2_01\src\javax is where javax is located.
    
    What am I doing wrong?

  - Can't avoid "References to generic type List<E> should be parameterized" warning here can I ?Hi,
    I'm writing some kind of gateway between 2 packages, whose a
    few classes have the same name (I need to bind these classes).
    
    So I'm retrieving the attributes of my source class1 and set my
    equivalent class2 in the other pkg with these attributes when
    methods names -and attributes- match.
    
    Excerpt from my method:
    1 public my.persistent.Pst mapFromProtocol(my.protocol.Pst src)
    2 {
    3 my.persistent.Pst target = new my.persistent.Pst();
    4 for (Iterator<my.protocol.Remark> it =
    src.getRemark().iterator(); it.hasNext(); )
    5 target.getRemark().add(it.next());
    6
    7 ... //many other attributes/objects to set too
    8
    9 return target;
    10 }
    
    In RAD the line 5 is underlined in yellow and it says "Type safety:
    The method add(Object) belongs to the raw type List. References
    to generic type List<E> should be parameterized".
    
    Is there a way to avoid this warning in my case, as I can't
    instantiate
    a List<Remark> lr = new ArrayList() of course... (because I have no
    method setRemark() in target)
    
    Thanks.
    Regards,
    Seb

  - hasNext?What is hasNext? I know you use it when you are reading from a file
    and it will stop when it has nothing more to read, but how would you
    use it? I have seen a couple of different examples of it, but all
    they do is make me more confused. I just can't seem to understand
    it...can anyone help?

    This is handled by the JSP container, i.e. on the server side.
    
    The path is hence relative to the JSP application.

    css is not JSP includes, but is part of the plain webbrowsing, i.e. handled
    from the *client* side.
    
    css is "requested for" by the the browser, i.e. the path is relative to the
    visible url.

  - Why do JARs made with JBuilder 2006 Enterprise not work outside IDE???Hi all,
    
    I have written a program in JBuilder 2006 Enterprise (Win NT, JRE 1.5)
    which works perfectly within the IDE.
    
    However, when I use JBuilder to create a JAR of my project and then try
    to run in from the command line it throws the run-time exception
    below...
    
    Exception in thread "main" java.lang.SecurityException: class
    "Com.package.MyPackage.MyExcpetion"'s signer information does not match
    signer information of other classes in the same package
    
    I have used JARs before but never come across this sort of error, maybe
    worth adding that the program uses JavaMail to send emails.
    
    More confusing, why does it work in JBuilder, but not outside?!?
    
    Any help would be greatly appreciated, i am stumped!

  - What is a "dirty read" ?Hi group,
    
    I am new to JDBC but have idea about Oracle transaction management. I
    am confused about JDBC documentation saying "dirty read"s allow
    changes made by a trasaction visible to another before it is
    committed. What does this mean ? Does it mean that the concurrent
    transaction can be from different connections ? If so how is it
    possible ? I believe read dirty reads are reads from dirty blocks
    which is accessible only by this session.
    
    TIA

  - AGLOCO- this worries GoogleHi,
    
    AGLOCO- this worries Google
    Bill Gates thinks Google should be worried!
    -------------------------------------------
    You must have heard by now about Agloco and how many people think it
    is going to be bigger than Google... Now Bill Gates is on record
    saying they have a great business model and that Google should be
    worried.
    
    Google search result produce - 1,400,000 web pages for Agloco.
    
    Google makes billions of $$$ and keeps it all for itself... Agloco
    one
    day is going to also make billions of $$$ except it will be completely
    shared out to its members!
    
    You make money with Agloco by using your computer as you would
    normally!
    
    Plus Agloco has a great referral pakage!
    So start building your network!

    It's all over the blogosphere and Bill Gates has been quoted as
    saying he believes it "will be the next big thing to hit the
    internet", so
    what is Agloco and will they really pay you for surfing the net?
    
    I too was sceptical when I heard about it but after spending a few
    hours googling and reading about it, I have not only come round to the
    idea but am now thinking it could really work and could really make
    us (that's me and all of you who are reading this) some money.

    Yeah, I think the policy should be consolidated, since java 1.1 is (for all I
    know) not packaged or availiable in Debian. Java-package supports nonfree
    runtimes starting from 1.3 and above. I assume that most of the software
    packaged in Debian these days will require a pretty modern runtime anyway.
    
    So, I'd suggest that the java(X)-runtime virtuals are removed in favour of a
    general "j-word-runtime" virtual to be provided by all runtimes capable of
    running programms written in the Java programming language.
    
    I propose using "j-word" instead of "java", because that is a time-honoured way
    of abbreviating four letter words that can not be said freely in English.[1]
    
    cheers,
    dalibor topic
    
    [1] As Sun Microsystems holds and and actively defends their Java(TM) trade
    mark, I would not recommend calling Kaffe a Java(TM) runtime, because, frankly,
    according to Sun Microsystem's rules for the usage of the trade mark, it is not
    a Java(TM) runtime.
    
    And that's fine by me, I don't feel that trying to rub off Sun's trade mark
    investment is a fair thing to do.[2] You can see on the kaffe.org web site how
    the Kaffe project tries to draw a clear line between Kaffe and Sun Microsystem's
    implementation. In order to avoid confusing people who dearly want the "Java(TM)
    Desktop System" GNU/Linux distribution, for example, rather than a free software
    runtime environment for programms written in the Java programming language (that
    is a safe use of the term "Java", btw. ;).
    
    [2] Just like I don't feel that Sun Microsystems attempts to market some of
    their clearly proprietary software as Open Source are a fine thing to do, like
    they tried to do with Java3D or JAI. See my comment at
    http://weblogs.java.net/blog/editors/archives/2005/02/working_with_th.html for a
    reference.
