    Only for enums.
    
    You can, of course, create your own Collection (Set, List, Map) of instances
    of any non-enum class. There is a more-or-less standard idiom for that,
    called a "registry".
    
    public class RegisteredInstance
    {
    private static final Map <String, RegisteredInstance> registry =
    new ConcurrentHashMap <String, RegisteredInstance> ();
    
    private final String name;
    
    public RegisteredInstance( String n )
    {
    if ( n == null )
    {
    throw new IllegalArgumentException( new NullPointerException(
    "name is null" ));
    }
    name = n;
    registry.put( name, this );
    }
    
    // add @Overrides for equals(), hashCode()
    // add other logic, including registry access
    }
    
    If you don't need associative lookup of the instances, you could use a Set or
    a List for the registry instead, and iterate at need.

  - Calendar get methodHello,
    
    I know there are a lot of issues with the Calendar class in Java (from
    my searches anyway), but I can't seem to find one for my simple
    question. When using the get methods of the calendar class, which
    timezone is it using? I've changed the default time zone using
    TimeZone.setDefault and have set the timezone of the Calendar object
    itself, but it seems to keep returning values for a GMT timezone. Where
    can I set it so the get methods of the Calendar class return the
    correct values for a timezone I specify?

  - tomcat - web service in a warHello I have the following problem. Normally when creating a JSP
    application I put all files in a web archive (.war file) which makes it
    possible to transfer the app to the webapps dir of another server and
    the app is deployed directly by the application manager.
    
    Also in the folder /axis/WEB-INF/classes I already have some
    precompiled web services, which are running perfectly.
    
    My question is, is there also a default way for creating .war file of a
    web service (and related files) in such a way that I can put the .war
    file in the axis dir on another server, and everything is going to work
    directly (auto-deployment in axis dir?)

  - Applet Security (File Transfer) QuestionsI've looked through a few books and various web sites. I'm still not clear
    on this and would like to make sure I have this right.
    
    I would like to use an applet in a web page. When the user presses an
    "UPLOAD" button, a file chooser would appear, the user could select a file,
    then the applet would read the file in and (instead of a regular upload),
    e-mail it to a specific address (a program will be reading the emailed
    files and processing them).
    
    I think I read that as long as the user specified a specific filename (like
    with a file chooser) and I converted the filename to a URL, I could read
    that file without having a signed applet. Is this true? Can I read in a
    specific file from an applet and e-mail it somewhere?
    
    And, if I can't, it looks like it is really easy to sign an applet. Is it
    as easy to create a signed class as it looks? If I upgrade the applet, do
    I have to have it re-signed or done over so the new version is recognized
    too?
    
    Thanks!

  - In Search Of: Abstract Algebra system.I'd like to use an abstract algebra engine of some sort to define 3d
    shapes and their intersections.
    
    For example, I would like to create a structure for a Sphere that is
    represented by (P - P0) dot (P - P0) <= R0*R0
    where R0 and P0 are constants.
    
    And the intersections of two Spheres, is represented by a system of
    inequalities:
    
    [(P - P0) dot (P - P0) <= R0*R0,
    (P - P1) dot (P - P1) <= R1*R1]
    
    I'd also like to be able to determine the intersection points of the
    surface of this system with a Ray.
    
    The actual goal is to create a Beam Casting project in Java. Beam
    Casting is like Ray Casting, but you start with a pyramid instead of a ray.
    
    I've found a library called Java Algebra System 2.0, but I'm confused on
    how to apply it toward my goal. If there is anything more specifically
    tailored to my problem, or someone can help me understand JAS, I'd
    greatly appreciate the info.
    
    Thanks,
    Daniel.

  - How to deprecated a method in a class?I would like to deprecated some methods in my
    class. So next time when people use those methods,
    they will get the warning messages during compiling.
    
    If you know how, please let me know.
    Thank Q very much in advance!

  - ATI or NVidia - best for Java3d?I'm contemplating purchasing a new graphics
    card, and would like to purchase one that
    performs well with Java3D.
    
    Which begs two questions:
    
    1. Which moderately high end card is
    better: ATI, or Nvidia? Given the current
    controversy relating to Half Life 2 and these two
    cards, I'm frankly a tad unsure!
    
    2. Is there a well-known benchmark written in Java3d
    to make the card choice a little easier?
    
    Many thanks in advance!

  - log4j as a static class ?Hello all,
    every example I found for log4j tells you to declare a final static
    variable to hold the reference to log4j Logger for each of your classes
    -by means of Logger.getLogger(Myclass.class)
    
    What about my approach?
    
    package mypackage;
    
    import org.apache.log4j.Logger;
    
    public final class Log {
    public static org.apache.log4j.Logger log =
    Logger.getLogger(Log.class);
    
    private Log(){
    }
    }
    
    Then, from within any class I need to log something, I simply call
    Log.log.myloglevel("something");
    
    Is this wrong?
    
    Thanks,
    regards

    My statement was true. That you can extend it to absurd lengths by pretending
    it is a mathematical claim and then find it lacking because it is not is a
    problem for you, not for me.

  - [signed applet] certification authorityHi,
    I have a signed applet (signed myself with jarsigner.exe).
    It works fine but the users get a warning message before accepting the
    applet to execute.
    Next step, is to have my certificate trusted by Verisign or other
    third party.
    Do you know any link to a site that would explain the procedure to
    follow in details ?
    Which certification authority would you recommend ? the cheapest ?
    
    thanks

  - Client Code for Axis - Newbie QuestionHi,
    
    I'm a first time Axis 1.1 user and trying to figure out how to write
    web services client code. I used WSDL2JAVA to create java source from
    the wsdl. I ended up with the following files...
    
    xxxx_Port.java
    xxxx_Service.java
    xxxx_ServiceLocator.java
    xxxxBindingStub.java
    xxxxRequest.java
    xxxxResponse.java
    
    Does anyone have some sample code they can share with me that shows
    the basics of how to set up the request and response parameters and
    then actually make the call to the web service. Not sure which
    classes or methods to use.
    
    Thanks

  - Add a computer language to NetbeansHello
    
    This may be a simple question. I searched in Google but I think I am
    using inapropiate words for the query and I don't get what I want.
    
    How can I add a syntax highlight for a new language, in my case X3D,
    to Netbeans?
    
    Any general tutorial?
    
    Thanks
    
    Jordi
    
    Note: Does someone already have done this with VRML or X3D?

  - Tools To Tackle New Code Base?Hi,
    
    I'm looking for advice on how to quickly come to grips with
    a large ( ~5000 files), undocumented codebase that's mostly Java
    ( compiles with Sun's command line compiler under Windows XP ).
    
    Here are some considerations.
    
    1) I'm new to Java, coming from a C++ background
    2) I need to get a handle on this quickly but also cheaply.
    3) I have no access to the original programmer.
    
    What tools are availble that might help me analyze and
    visualize the relationship between various modules and classes
    in this project? In the past, with large C++ codebases I've
    looked at Doxygen but the learning curve seemed very steep
    and I never did figure out the graphical tools.
    
    Appreciate any advice, the more concrete the better.
    If there's a different forum I should be posting this in please let
    me know.
    
    TIA,

  - Transparency in Java ImagingHi all!
    
    When I have multiple images in Java (I'm using JAI, but I thing this has
    to do with ColorModel, which is present in AWT) which I want to stack
    above each other, is there any possibility to define white as
    "transparent", i.e. whenever an image contains white pixels they should
    not be drawn... any ideas?
    If this is impossible, how else do I use transparency when drawing
    images? (i.e. how can I stack them, without each overwriting the image
    below it)?
    
    thanks in advance and kind regards,

  - Networked version of Swing (X windows style)?Hello,
    
    I was wondering if something like that exists or if someone has ever
    thought about it:
    
    Instead of Swing updating the local screen and obtaining events from
    the local mouse & keyboard, it may be useful in some cases to have a
    networked version of Swing, just like XWindows.
    
    Imagine a workstation connecting to a remote JVM that starts a typical
    swing application. But this JVM/Classpath/etc is configured so that all
    Swing calls are serialized to the remote workstation, where all the
    screen updates are made. And viceversa for the mouse and keyboard.
    
    Probably Swing is not well designed for this kind of "pluggability"...
    in any case it would be an interesting thing to have.
    
    The key requirement here is that preexisting AWT/Swing applications can
    be remotely executed without modification.
    
    Is there any project or product that does this?
    If not, any ideas on how to implement it?
    
    Thanks,
    
    Luis.

  - Bypassing Struts validator - why doesn't bCancel=true work?Hi there,
    
    I'm trying to bypass the Struts validator sometimes on my page. I'm
    using JSP and Struts 1.1.
    
    Basically I have a submit button that submits a form. The Struts
    validator component is working great for client-side validation of the
    contents of this form.
    
    However, now I've been asked to implement a drop down on the page that
    repopulates another drop down box when it is changed. Because of the
    size of the data, I'm doing this server side, not client side. That
    is, I want the page to refresh and then repopulate these fields.
    
    This means I have to bypass the validator to ignore anything the user
    might have already entered in the fields. I've read all over the
    newsgroups how putting "bCancel=true" in your onclick or onchange
    method should do the trick, but it doesn't work for me. When I create
    my select box like this
    
    <html:select property="countyId" tabindex="1"
    onchange="bCancel=true;document.forms[0].method.value='changeCounty';document.forms[0].target
    = '_self';document.forms[0].onsubmit();document.forms[0].submit();">
    
    and then change the drop down box, nothing happens. Control never
    gets to my changeCounty action. I've checked that. But I also don't
    get any validation messages from the validator, despite there being
    validation errors on the page when I change the drop down box. So
    it's like the validator function doesn't execute either. (The method
    value is there because I'm using a DispatchAction class.)
    
    Is the validation function running or not? How can I bypass the
    validation and still submit the form?
    
    Thanks for the help!

  - Log4j - dealing with multithreaded invocations?Hi,
    
    I have a class with 4 methods. I want to use Log4j to log messages for
    each of these methods to a common log file.
    
    Ideally I would like the log messages for each method to be seperated
    from the others. But if multiple users were to invoke the methods at
    the same time, then the messages in my log file would be jumbled up
    with the others.
    
    I can probably try making the methods synchronized so i dont get into
    this sort of trouble, but logging by itself doesn't seem to be a good
    enough reason to be making methods synchronized.
    
    What approach can I use to deal with this?
    
    Thank you,
    Rohit.

  - -Xms setting makes IE exitFolks,
    
    My company uses a Java based server application, and Internet Explorer
    on our client machines. Recently our server application was upgraded,
    and instead of needing Microsoft's JVM on the client machines we are
    now using Sun Java version 1.4.2_08.
    
    Performance around applet caching was poor, and the recommended cure
    for that was to set "-Xms128m -Xmx256m" in the Java Runtime
    Parameters from the Java control panel. On machines that have never had
    the Microsoft JVM installed this fixed the problem.
    
    However, on machines that have had the JVM installed, this causes the
    browser to exit whenever an applet is started. From doing some research
    it seems this problem is usually caused by a conflict between the Sun
    and Microsoft Java components. So the JVM was uninstalled using the
    process detailed here: -
    http://www.java.com/en/download/help/uninstall_msvm.xml#cli
    (That is identical to the steps found on Microsoft's knowledgebase)
    
    After a lot of experimentation I have found that setting only the
    starting memory setting "-Xms64m" does not cause any problems.
    However this is clearly far from ideal and I am looking for a better
    solution. Does anybody have any suggestions?

  - Switching GTK theme on Java 1.6 (i.e., mustang)I'm at a loss on how to change on-the-fly the theme (i.e., resource) for the
    GTK look and feel on Java 1.6 (Mustang). On 1.5 it was a simple matter of
    setting a system property (i.e., "swing.gtkthemefile") like this:
    System.setProperty ("swing.gtkthemefile", fGTKThemeFile);
    
    But on Mustang it has been completely changed.
    
    It is probably just as easy but I'm missing something?
    
    Thanks.

    Quality First Software (QFS) is pleased to announce the release of
    version 1.4 of qftestJUI - The test tool for Java User Interfaces.
    
    The is the second medium upgrade for qftestJUI since the release of
    version 1.0 in October 2002. Along with a greatly improved and
    extended tutorial, the highlights of this upgrade are support for Java
    WebStart, extended support for distributed development through an
    include mechanism and dependency tracking across multiple test-suites.
    
    An evaluation version is freely available for download at
    
    http://www.qfs.de/en/qftestJUI/download.html
    
    where you'll also find a link to the latest release notes.
    
    What is it?
    ===========
    
    Based on capture/replay, but extending far beyond, qftestJUI manages
    the creation and execution of automated tests for Java/Swing
    applications with a graphical user interface. It runs on Windows and
    all major Unix systems with JDKs from 1.1.8 to 1.4.2.
    
    The key feature of qftestJUI is an exceptionally high test
    reusability, minimizing the effort necessary for regression testing.
    Intuitive graphical design of tests reduces the cost of introducing
    qftestJUI into the QA process. Additionally, qftestJUI sports a set of
    features for the advanced user such as variables, procedures and
    scripting. Extensive documentation, including a tutorial, is available
    for users approaching the product with different background and skill
    levels.

  - XApool +multiple replicated nodesHi All,
    
    I am creating a small research system for testing various fall over
    algorithms in a distributed database situation and and have been looking at
    using XApool as a possible JDBC XA proxying and load balancing solution. I
    am just wondering if anyone else has had any luck getting the XApool system
    to talk to different oracle hosts ? I plan to use the development/personal
    edition of oracle and their thin jdbc driver, which is also XA compatible.
    Anyway, if someone could point me in the right direction I would be much
    appreciated :) I've had a look at the docs but cannot see where I add the
    different nodes into the pool ???
