  - Kodak v Sun; patent law gone all wrong?If in 1995 Sun Microsystems, Inc. changed the name of OAK to Java and
    modified the code for the Internet, how did Sun infringe the patents
    Kodak acquired from 'Wang' in 1997? What damning evidence did Kodak have
    that in 1995, Sun incorporated the 'Khoyi' method, thereby infringed the
    patents?
    
    The "Khoyi patents", named after Dana Khoyi - an ex-Wang engineer,
    "covered a method by which a program can get help from another computer
    application to complete a task", which they claim is the way Java
    operates and that Sun has therefore infringed the Khoyi patents..
    
    Whose intellectual property is Java? Surely Java was patented in 1995,
    just after the change? Were the Wang 'Khoyi' patents and Sun 'Java'
    patents identical? I take it Wang patented their software years before
    Sun did? Does anyone know what year?
    If the two were identical or similar, isn't it possible that in a world
    of 6,395,379,218 people, it is more than likely that two or more people
    might have the same ideas? I find it difficult to believe that Sun
    infringed Kodak's patents, but rather that Kodak got a little too
    desperate given it's not doing so well in this 'digital' age and had to
    lay off some 15,000 jobs worldwide a month ago "because of declining
    demand for consumer film and colour photographic paper"..
    
    How on earth can an eight member jury of lay people understand "patent
    law" to deliberate and find in favour of Kodak? I don't understand how a
    jury could possibly fathom the complexities of patent law, without any
    background or education in the legal arena, and find in Kodak's favour?
    
    There are a lot of questions that I have to things that don't add up,
    like; Java is freely downloadable, so how can any jury find in favour of
    Kodak who wanted damages of $1.06 billion in past royalties??
    How did Kodak prove that Sun had access to its patents?
    If Kodak is so sure that Sun infringed patents, why did it bother to
    agree to the $92 million settlement? Surely they believed they would be
    awarded $1.06 billion or even more..? accepting such a small amount (for
    them) is silly, it sounds to me like they thought they wouldn't win..
    
    This case is a perfect example why juries should NOT be involved in
    patent suits.
    
    Sun should not have settled the case, it should have seen the case
    through and appealed the prospective travesty of justice..
    
    Does anyone agree with me here? I'd be interested in other people's
    opinions on this issue. A public debate, anyone?

  - struts or expresso or turbine?hi..
    
    i've been reading the struts developer and it mentions that i want to
    create a web application from scratch i should use either turbine or
    expresso..
    
    i'm looking for a free, main stream web framework, that can be used
    with eclipse.
    
    can anyone tell me about any of these and how they compare?

  - ClassDefNotFoundI'm having a lot of trouble trying to run small applications that have compiled
    fine. No matter what I try attempting to execute any class file gives me this
    message:
    java -classpath "." TryWindow.class
    Exception in thread "main" java.lang.NoClassDefFoundError: TryWindow/class
    
    I've tried setting my class path the the current working directory in my
    environment, specifying the current directory with the -classpath switch,
    specifying "" with the class path switch, running it as an unprivileged
    user, running it as root, and manipulating the permissions and the result
    has been the same. I also rebooted to Windows and tried it with the
    NetBeans ide. What am I doing wrong? According to what I have read
    java should be able to find classes in the current working directory.
    
    Here is the code for the example I tried:
    
    import javax.swing.*;
    
    public class TryWindow{
    static JFrame aWindow = new JFrame("This is the Window Title.");
    public static void main()
    {
    aWindow.setBounds(50, 100, 400, 150);
    aWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    aWindow.setVisible(true);
    }
    }
    
    Thanks in advance.

  - problem with methods on a bound classHi,
    
    I've been fiddling around with JavaScript.pm, which is very cool, I have to
    say, I've bound a class, and sucessfully bound an object, and i can read
    from the object's properties, and execute it's getter/setter functions, but
    for some reason i cannot get the object's methods to work..
    
    here's a cleaned up version of what i've been testing with:
    
    $js->bind_class(
    name=>'Foo',
    methods=>{
    test => \&Foo::test
    },
    properties=>{
    testy =>{
    flags => JS_PROP_READONLY | JS_PROP_ACCESSOR,
    getter => \&Foo::test_getter,
    }
    }
    );
    my $obj = new Foo();
    $js->bind_object('obj', $obj)
    
    (where package Foo has a 'test' method)
    
    ....
    
    now in js: 'obj.testy' (the property) works fine, but 'obj.test()' (method)
    just doesn't.. there seems to be no indication that it's successfully bound
    (everything just says it's not defined).. getters and setters work, but
    methods just don't seem to..
    
    Any clues as to what's going on?

  - OOM detectionHi,
    
    I'm looking for a way to detect that the JVM is reaching an out of
    memory situation. But, I don't want to do this by means of catching
    an OutOfMemoryError, because by that time the ship is already
    sinking. I came up with a solution that uses the Reference Objects
    API, but I don't know if it will do the job correctly.
    Below is a demo. Please give me some feedback on this.
    I also tried it out using a SoftReference, but then it gives an
    OutOfMemoryError eventually. Is this behavior JVM dependent?
    
    CC me,
    Frank.
    
    /*
    * Run with: java -verbose:gc Test
    */
    import java.lang.ref.*;
    import java.util.*;
    
    public class Test extends Thread {
    
    private ReferenceQueue queue = new ReferenceQueue();
    private Reference pr;
    
    private static Stack stack;
    
    public void run() {
    while(true) {
    Object o = new Object(); // dummy object
    pr = new WeakReference(o, queue);
    o = null;
    try {
    queue.remove(); // when our dummy object gets finalised we continue here...
    }
    catch(InterruptedException e) { }
    System.out.println("OOM");
    stack.clear(); // prevent OutOfMemoryError here...
    }
    }
    
    public static void main(String [] args) {
    stack = new Stack();
    new Test().start();
    while (true) {
    stack.push(new Object());
    }
    }
    
    }

  - Loading jdbc jars and classes in the application default classloader dynamically..In our application, the JDBC jar files are stored in pre configured
    location. say c:\server\libs\1.jar, 2.jar
    
    We don't want to include these jars file in the class path. However,
    whenever, we receive a jdbc request, we want to be able to load all the
    jars located in this location and then do the basic jdbc call
    sequence...
    
    e.g. Class.forname("com.mydriver.SQLServerDriver");
    Connection conn = DriverManager.getConnection(
    "jdbc:mydriver:sqlserver://sqlserver1:1433;DatabaseName=Mydb;User=****t;Password=*****"
    );
    
    How ca i do this?
    
    I tried the following code but doesn't help... I keep getting the
    java.sql.SQLException: No suitable driver error. After somedebugging, I
    found that the Drivermanager uses some getCallerClassLoader and that
    doesn't match the class loader of com.mydriver.SQLServerDriver.
    
    How do i make the loading using the default class loader at the same
    time including those jar files?
    
    String x = "kjds";
    File f = new File("D:/server/libs");
    File[] jarFiles = f.listFiles(new ExtentionFilter("jar"));
    
    URL[] urls = new URL[jarFiles.length+1];
    int i=0;
    for(;i< jarFiles.length;i++){
    try{
    urls[i] = jarFiles [i].toURL();
    }catch(Exception ex){}
    }
    
    ClassLoader z = new URLClassLoader(urls,
    x.getClass().getClassLoader());
    
    try
    {
    //Class DriverClass =
    z.loadClass("com.mydriver.SQLServerDriver");
    //Driver dd = (Driver)DriverClass.newInstance();
    // DriverManager.registerDriver(dd);
    Driver x =
    (Driver)Class.forName("com.actuate.actuatedd.jdbc.sqlserver.SQLServerDriver",
    true, z);
    String cnstr =
    "jdbc:mydriver:sqlserver://sqlserver1:1433;DatabaseName=Mydb;User=****t;Password=*****"
    
    Connection conn = DriverManager.getConnection( cnstr );

  - question concerning downcasthello guys,
    
    Curiosity made me take a look at the tomcat 's implementation of the servlet
    API.
    
    The HttpServlet class, which can be subclassed by http servlets, contains
    the "service" method that is invoked by the servlet container in order to
    pass a web request to a particular servlet. The method accepts a
    ServletRequest and ServletResponse object as arguments, and downcasts them
    to HttpServletRequest and HttpServletResponse respectively and then calls a
    "service" method implemented by the same class:
    public void service(ServletRequest req, ServletResponse res) throws
    ServletException, IOException
    {
    HttpServletRequest request;
    HttpServletResponse response;
    try {
    request = (HttpServletRequest) req;
    response = (HttpServletResponse) res;
    } catch (ClassCastException e) { throw new ServletException("non-HTTP
    request or response"); }
    service(request, response);
    }
    }
    
    How is it possible to do so, as the ServletRequest interface is more generic
    than the HttpServletRequest (they have a hereditary relationship
    HttpServletRequest== extends ServletRequest)?
    
    TIA

  - Writing a generic InputBoxHi,
    
    I wont tell my old way but I have rewritten my InputBox class as having
    the following important snippets:
    
    public class InputBox extends JDialog {
    private ActionListener okAction;
    
    public InputBox(ActionListener a, JFrame f, String label, String
    title, String defaultText) {
    okAction = a;
    getMyOkButton().addActionListener( new ActionListener() {
    public void actionPerformed(ActionEvent e) {
    okAction.actionPerformed(e);
    dispose();
    }
    });
    public String inputText() {
    return control.getText();
    }
    }
    
    Code uses it as follows
    
    ActionListener okAction = new ActionListener() {
    public void actionPerformed(ActionEvent e) {
    try {
    myObject.setURLName(hyperlinkInputBox.getInputText());
    } catch (Exception ex) {
    Debug.LogException(this, ex);
    }
    }
    };
    hyperlinkInputBox = new UIInputBox(okAction, "Insert
    Hyperlink",parentFrame,"URL:",null,300);
    hyperlinkInputBox.setVisible(true);
    
    I dislike having to make hyperlinkInputBox a private variable in the
    calling class in order to reference it within the okAction
    ActionListener. Same goes for myObject.
    
    I guess it is not *too* shabby but can anyone improve my architecture?
    
    thanks

  - Signed code runs using WebStart in 1.4 but not 1.5I have a signed application that runs flawlessly under WebStart in 1.4
    JDKs/JREs (on WinXP/2K, Linux and MacOS X) that refuses to run under
    WebStart in 1.5 JDKs (on both Windows and Linux; haven't tried on MacOS).
    
    The error occurs when the certificate is validated (this is from 1.5.0_03):
    
    java.security.cert.CeritificateException: Check leaf key usage failed in
    certificate
    at
    com.sun.deploy.security.CertUtils.checkUsageForCodeSigning(CertUtils.java:102)
    ...
    
    I've tried 1.5.0 (Windows & Linux) and 1.5.0_03 (Linux), with the same
    error each time. I know of several others who have also been unable to
    run my application under 1.5.0; I don't know of anyone who has been able
    to run it under 1.5.0.
    
    I'm using a code-signing certificate bought from Thawte. I've tried
    using jarsigner from both 1.4 and 1.5, but get the same results each
    time. From the exception, it seems likely that 1.5.0 doesn't believe
    that the certificate used to sign the code can be used for code-signing,
    but I don't know why it would come to this conclusion.
    
    I've successfully run this app using WebStart under 1.4.2_01, 1.4.2_03
    and 1.4.2_06, on Linux and WinXP/2K (ie these JDKs all successfully
    validate the certificate used to sign the app and prompt the user as
    expected), plus various Apple 1.4 JVMs.
    
    Google hasn't been of any assistance, so any help would be greatly
    appreciated.
    
    Cheers,

  - [JSF] How to determine the WEB-INF path of the current web application?Hello everybody,
    
    I'm new to the Java world writing my first Java web application with JSF 1.1
    and Tomcat 5.5. I have the following problem:
    
    I've created a Properties file and placed it in the WEB-INF directory of the
    web application. The file contains several configuration options like
    database parameters. I want to open this file within my web application
    with a FileInputStream which I pass to the load() method of a Properties
    object. Unfortunately I was unable to determine the path of the WEB-INF
    directory of the current web application. I don't want to write the path
    hard coded into the source code.
    
    Maybe my way is not the correct "Java way" of solving this kind of problem
    so I'm not only interested in an answer to my question but also in
    suggestions how to solve this problem in a better way.
    
    Thank you!

So what precisely is the problem you're having? Can you connect to the
database? Is it running an insert query or an update query? We aren't
telepathic, people are happy to help with a specific problem but
expecting someone to second guess what you are doing won't get results.

  - Eclipse + Tomcat plugin: problem with automatic class reloadingHi all,
    I am having a problem using the DevLoader that comes with the eclipse
    plugin for Tomcat from sysdeo.
    It is loading classes okay from locations.
    But it is not reloading them when they change.
    The reloading works okay for a class that is WEB-INF/classes.
    
    Here are the details:
    Versions:
    eclipse version 2.1.1
    eclipse Tomcat plugin V 2.2.1
    Tomcat version 4.1.29
    JDK 1.3.1_04
    
    I have extracted the DevLoader zip into [Tomcat Home]/server/classes
    directory.
    The tomcat server is using this DevLoader to load the classes.
    I set the debug level in my web-app Context in conf/server.xml for the
    loader to 4.
    (<Loader className="org.apache.catalina.loader.DevLoader"
    reloadable="true" debug="4"/> )
    Logging is redirected to the console.
    
    I can see output in the console that shows that it added my classes
    location:
    [DevLoader] added file:/C:/dev/workspace/Test/classes/
    
    This is the location to find a class ims.test.TestServlet.
    And it is able to find this class:
    
    WebappClassLoader: loadClass(ims.test.TestServlet, false)
    WebappClassLoader: Searching local repositories
    WebappClassLoader: findClass(ims.test.TestServlet)
    WebappClassLoader: findClassInternal(ims.test.TestServlet)
    WebappClassLoader: loadClass(javax.servlet.http.HttpServlet, false)
    WebappClassLoader: Delegating to parent classloader
    WebappClassLoader: Loading class from parent
    WebappClassLoader: Returning class class ims.test.TestServlet
    WebappClassLoader: Loaded by WebappClassLoader
    available:
    delegate: false
    repositories:
    /WEB-INF/classes/
    required:
    
    I find it strange that my location
    (file:/C:/dev/workspace/Test/classes/) is under the repositories.
    
    If change the code (recompile) ims.test.TestServlet it is NOT
    reloaded.
    However, if I have a class that is to be found in WEB-INF/classes
    e.g. I have a different class ims.TestServlet that is in
    WEB-INF/classes/
    
    WebappClassLoader: loadClass(ims.TestServlet, false)
    WebappClassLoader: Searching local repositories
    WebappClassLoader: findClass(ims.TestServlet)
    WebappClassLoader: findClassInternal(ims.TestServlet)
    WebappClassLoader: Returning class class ims.TestServlet
    WebappClassLoader: Loaded by WebappClassLoader
    available:
    delegate: false
    repositories:
    /WEB-INF/classes/
    required:
    
    Then if I change ims.TestServlet it IS reloaded.
    
    WebappClassLoader: Resource '/WEB-INF/classes/ims/TestServlet.class'

  - Open File componentThe usual file open component on a form consists of a label describing
    the file, a text field that accepts a file name and a command button
    that brings up a file chooser.
    
    Is there a "standard" component that does this preferably a bean that
    can be added to NetBeans?

  - About JEditorPaneI wrote a plugin to NetBeans 5.0 which displays html pages in a
    JEditorPane, when i clicked a file in explorer.
    JEditorPane is in the topcomponent class.Also JTree(Explorer) in a
    other topcomponent class.
    I use setPage(URL url) method. But its not working properly.That means
    the editor pane displays the html code of the file
    But i wrote it as standalone application, it displays correctly.
    Explain what is the problem here.

    Now this I didn't realize.
    
    I had no idea you had experience in teaching children? I have been
    looking for ideas to teach and stimulate desire to learn logic and
    mathmatics in younger children. It is my belief that subjects which are
    typically reserved for higher education such as trig, calculus, discrete
    math, deductive logic could all be started before children ever leave
    elementary. The trick would only be to interest the children, and present
    the material in a way that it could be absorbed.
    
    Can you offer any insight into this matter? Into teaching children how to
    make games? What engine did you use (I suppose you were using Java).

  - Tomcat & SSL & a certificate generated by VerisignAttempting to SSL enable tomcat 4.04. Have implemented JSSE and SSL
    works fine when I create a keystore with a self generated certificate.
    
    keytool -genkey -alias tomcat -keyalg RSA -keystore .keystore
    
    We now want to cutover using a production certificate. We create a
    .cer file by accessing our production web site and export the
    certificate to a .cer file.
    
    then using the keytool we import the .cer file
    
    keytool -v -import -file prod.cer -keystore .keystore
    
    When we inspect the .keystore file using the -list switch we see the
    certificate.
    
    Now when we implement the .keystore in tomcat, only the original self
    generated certificate is presented.
    
    So, using the keytool we delete the original self generated
    certificate so we are only left with the newly imported production
    certificate.
    
    When we implement this .keystore file with only the production cert,
    the browser and tomcat fail to negotiate. Tomcat binds to port 8843
    but the ssl negotiation is hosed.
    
    Has anybody ever gottent tomcat & ssl to work with a non self
    generated certificate? Can you please help?
    
    Thanks,

  - Switch on StringsHello, I have code that looks like this:
    
    switch(myColor){
    case "blue":
    {
    this.setForeground(Color.blue);
    break;
    }
    case "red":
    {
    this.setForeground(Color.red);
    break;
    }
    case "green":
    {
    this.setForeground(Color.green);
    break;
    }
    default:
    {
    this.setForeground(Color.blue);
    }
    }
    
    myColor is a String being read in from an HTML file PARAM line.
    The above code doesn't work, because switch doesn't work with strings.
    So I was wondering how else I can do this...

  - why "synchronized" with wait/notify ?I know the language requires it and what exaclty happens with
    wait/notify.
    
    BUT it appears that the whole wait notify protocol should work just as
    well without acquiring a monitor lock on the target object...
    
    I've read something about why we need to have a thread own a monitor on
    the object (key) that is waiting on, something about race condition.
    but icant wrap my head around it, could someone care to walk me through
    it please using a scenario where it would not work as expected.
    
    So why would this not work (logic- forget the illegal monitor state
    execption)
    ThreadA
    |
    |
    key.wait() //suspend threadA and add to waitset of key
    
    ThreadB
    |
    |
    key.notifyAlll; //Wake up one of the threads in the waitset of key
    
    Thanks
